Question 630

A network controller reaches NETCONF over SSH but uses a shared administrative credential for all developers. Which TWO complementary steps provide the most defensible remediation and its supporting assessment? Select TWO.

  1. Inspect device version, benchmark applicability, privileged account policies, enabled services, management exposure, and exception approvals.
  2. The corrected handshake establishes valid security associations without weakening approved encryption or authentication standards.
  3. Use SNMPv3 with authentication and privacy where appropriate and restrict agents to approved management sources and read views.
  4. Protect programmable device management with authenticated endpoints, transport encryption, role authorization, and change transaction logging.
  5. Inspect SSH/HTTPS management services, NETCONF or RESTCONF configuration, model schema, access roles, and operation results.

Explanation

Correct Answers

D:

Protect programmable device management with authenticated endpoints, transport encryption, role authorization, and change transaction logging. This control addresses the failure mechanism and narrows the enforcement boundary. Programmable interfaces are management planes with security obligations comparable to CLI access; enabling RESTCONF does not itself validate an automation request. Confirm pre-change conditions using: Inspect SSH/HTTPS management services, NETCONF or RESTCONF configuration, model schema, access roles, and operation results. This is the implementation portion of the complementary pair. Situation: A network controller reaches NETCONF over SSH but uses a shared administrative credential for all developers.

E:

Inspect SSH/HTTPS management services, NETCONF or RESTCONF configuration, model schema, access roles, and operation results. This checks the relevant condition before an engineer modifies production access or detection behavior. Programmable interfaces are management planes with security obligations comparable to CLI access; enabling RESTCONF does not itself validate an automation request. The controlled response would be: Protect programmable device management with authenticated endpoints, transport encryption, role authorization, and change transaction logging. This supplies the diagnostic evidence needed for the complementary action. Situation: A network controller reaches NETCONF over SSH but uses a shared administrative credential for all developers.

Incorrect Answers

A:

Inspect device version, benchmark applicability, privileged account policies, enabled services, management exposure, and exception approvals. This step could matter for CIS device configuration baseline assessment but is not part of the required complementary pair for this case. The paired steps are: Protect programmable device management with authenticated endpoints, transport encryption, role authorization, and change transaction logging. and Inspect SSH/HTTPS management services, NETCONF or RESTCONF configuration, model schema, access roles, and operation results. Situation: A network controller reaches NETCONF over SSH but uses a shared administrative credential for all developers.

B:

The corrected handshake establishes valid security associations without weakening approved encryption or authentication standards. This step could matter for FTD IKE negotiation failure isolation but is not part of the required complementary pair for this case. The paired steps are: Protect programmable device management with authenticated endpoints, transport encryption, role authorization, and change transaction logging. and Inspect SSH/HTTPS management services, NETCONF or RESTCONF configuration, model schema, access roles, and operation results. Situation: A network controller reaches NETCONF over SSH but uses a shared administrative credential for all developers.

C:

Use SNMPv3 with authentication and privacy where appropriate and restrict agents to approved management sources and read views. This step could matter for SNMPv3 authenticated encrypted polling but is not part of the required complementary pair for this case. The paired steps are: Protect programmable device management with authenticated endpoints, transport encryption, role authorization, and change transaction logging. and Inspect SSH/HTTPS management services, NETCONF or RESTCONF configuration, model schema, access roles, and operation results. Situation: A network controller reaches NETCONF over SSH but uses a shared administrative credential for all developers.

Question 631

An engineer installs a kernel telemetry probe on mixed Linux versions and sees gaps on unsupported nodes. Which observed result BEST confirms that the security requirement is met?

  1. A critical vulnerable dependency blocks promotion and approved remediation produces an auditable releasable artifact.
  2. External guests cannot read restricted resources and an integration token cannot access unrelated customer tenants.
  3. Workload process-to-network events are attributable without destabilizing the monitored host or overstating enforcement abilities.
  4. A changed unsigned image or privileged unexpected workload is blocked from the approved deployment process.

Explanation

Correct Answer

C:

Workload process-to-network events are attributable without destabilizing the monitored host or overstating enforcement abilities. This is an observable acceptance condition, rather than an assumption that enabling a feature alone proves security. eBPF enables efficient programmable Linux kernel instrumentation, but security capabilities depend on the actual sensor and deployment configuration. Situation: An engineer installs a kernel telemetry probe on mixed Linux versions and sees gaps on unsupported nodes.

Incorrect Answers

A:

A critical vulnerable dependency blocks promotion and approved remediation produces an auditable releasable artifact. This outcome tests CI CD container and application security lifecycle and is not sufficient proof of the stated requirement. Here the relevant validation is: Workload process-to-network events are attributable without destabilizing the monitored host or overstating enforcement abilities. Situation: An engineer installs a kernel telemetry probe on mixed Linux versions and sees gaps on unsupported nodes.

B:

External guests cannot read restricted resources and an integration token cannot access unrelated customer tenants. This outcome tests SaaS configuration and tenant boundary protection and is not sufficient proof of the stated requirement. Here the relevant validation is: Workload process-to-network events are attributable without destabilizing the monitored host or overstating enforcement abilities. Situation: An engineer installs a kernel telemetry probe on mixed Linux versions and sees gaps on unsupported nodes.

D:

A changed unsigned image or privileged unexpected workload is blocked from the approved deployment process. This outcome tests Container workload identity and image governance and is not sufficient proof of the stated requirement. Here the relevant validation is: Workload process-to-network events are attributable without destabilizing the monitored host or overstating enforcement abilities. Situation: An engineer installs a kernel telemetry probe on mixed Linux versions and sees gaps on unsupported nodes.

Question 632

Remote staff can sign in to Secure Access but the private finance app fails after its internal address changes. Which Cisco security control or operational response BEST addresses the stated need?

  1. Validate private application connector capacity and connectivity alongside identity decisions and policy enforcement before relaxing restrictions.
  2. Select SSE for cloud-delivered security functions and account for SD-WAN or network connectivity when describing a complete SASE deployment.
  3. Publish approved private applications through Secure Private Access with least-privilege identity and device conditions rather than broad network tunnels.
  4. Apply AI service visibility and policy to protect sensitive inputs, approved destinations, and user identity when staff use external generative AI tools.

Explanation

Correct Answer

A:

Validate private application connector capacity and connectivity alongside identity decisions and policy enforcement before relaxing restrictions. This control addresses the failure mechanism and narrows the enforcement boundary. A successful user login proves authentication, not connector reachability or correct backend application mapping. Confirm pre-change conditions using: Inspect connector registration, reachability to application backends, DNS resolution, user session logs, and connector redundancy. Situation: Remote staff can sign in to Secure Access but the private finance app fails after its internal address changes.

Incorrect Answers

B:

Select SSE for cloud-delivered security functions and account for SD-WAN or network connectivity when describing a complete SASE deployment. This response applies to SSE compared with SASE architecture, not the controlling requirement in this case. Security Service Edge focuses security functions; Secure Access Service Edge combines networking or WAN capabilities with cloud-delivered security in an integrated architecture. For this scenario, the targeted action is: Validate private application connector capacity and connectivity alongside identity decisions and policy enforcement before relaxing restrictions. Situation: Remote staff can sign in to Secure Access but the private finance app fails after its internal address changes.

C:

Publish approved private applications through Secure Private Access with least-privilege identity and device conditions rather than broad network tunnels. This response applies to Cisco Secure Access private app access, not the controlling requirement in this case. Zero-trust private access grants application-scoped connectivity; being authenticated to the cloud portal does not imply authorization to every private network. For this scenario, the targeted action is: Validate private application connector capacity and connectivity alongside identity decisions and policy enforcement before relaxing restrictions. Situation: Remote staff can sign in to Secure Access but the private finance app fails after its internal address changes.

D:

Apply AI service visibility and policy to protect sensitive inputs, approved destinations, and user identity when staff use external generative AI tools. This response applies to AI application guardrails and shadow AI, not the controlling requirement in this case. A corporate AI policy requires enforceable data handling and approved services; blocking a few keywords does not alone control all exfiltration paths. For this scenario, the targeted action is: Validate private application connector capacity and connectivity alongside identity decisions and policy enforcement before relaxing restrictions. Situation: Remote staff can sign in to Secure Access but the private finance app fails after its internal address changes.

Question 633

A suspected ransomware sample sleeps during a short sandbox window and returns an inconclusive initial verdict. Which Cisco security control or operational response BEST addresses the stated need?

  1. Interpret Cisco Secure Endpoint detection events using file, process, device, event time, and connected-host context before declaring an infection scope.
  2. Deploy appropriate Cisco Secure Client modules for supported connectivity and endpoint posture requirements and verify the component state.
  3. Use supported Cisco Secure Malware Analytics sandbox assessment to investigate suspicious files while distinguishing dynamic analysis from known-good reputation.
  4. Prioritize Secure Endpoint alerts by severity, current host risk, file action, correlated detections, and business criticality.

Explanation

Correct Answer

C:

Use supported Cisco Secure Malware Analytics sandbox assessment to investigate suspicious files while distinguishing dynamic analysis from known-good reputation. This control addresses the failure mechanism and narrows the enforcement boundary. Sandbox dynamic analysis records execution behavior in a controlled environment; a clean result cannot prove every variant is harmless. Confirm pre-change conditions using: Inspect sample provenance, sandbox verdict, observed process/file/network behavior, detonation environment, and indicator confidence. Situation: A suspected ransomware sample sleeps during a short sandbox window and returns an inconclusive initial verdict.

Incorrect Answers

A:

Interpret Cisco Secure Endpoint detection events using file, process, device, event time, and connected-host context before declaring an infection scope. This response applies to Secure Endpoint detection event trajectory, not the controlling requirement in this case. An endpoint detection event records what the connector observed and did; a block, quarantine, detection, and retrospective verdict are distinct states. For this scenario, the targeted action is: Use supported Cisco Secure Malware Analytics sandbox assessment to investigate suspicious files while distinguishing dynamic analysis from known-good reputation. Situation: A suspected ransomware sample sleeps during a short sandbox window and returns an inconclusive initial verdict.

B:

Deploy appropriate Cisco Secure Client modules for supported connectivity and endpoint posture requirements and verify the component state. This response applies to Cisco Secure Client module and posture visibility, not the controlling requirement in this case. Secure Client is a modular endpoint platform; enabling a VPN tunnel does not automatically mean all security modules or postures are active. For this scenario, the targeted action is: Use supported Cisco Secure Malware Analytics sandbox assessment to investigate suspicious files while distinguishing dynamic analysis from known-good reputation. Situation: A suspected ransomware sample sleeps during a short sandbox window and returns an inconclusive initial verdict.

D:

Prioritize Secure Endpoint alerts by severity, current host risk, file action, correlated detections, and business criticality. This response applies to Endpoint malware event prioritization, not the controlling requirement in this case. Alert counts alone do not establish incident severity; containment status and evidence of active execution change urgency. For this scenario, the targeted action is: Use supported Cisco Secure Malware Analytics sandbox assessment to investigate suspicious files while distinguishing dynamic analysis from known-good reputation. Situation: A suspected ransomware sample sleeps during a short sandbox window and returns an inconclusive initial verdict.

Question 634

A contractor registers a personal tablet and receives the same internal access as a managed payroll workstation. Which Cisco security control or operational response BEST addresses the stated need?

  1. Enforce appropriate Cisco Duo MFA and device trust checks for protected applications, considering user role and device security status.
  2. Combine device profiling evidence with authentication and posture to make appropriate Cisco ISE authorization decisions while acknowledging unknown device types.
  3. Configure network access device 802.1X to use Cisco ISE RADIUS decisions and verify supplicant, authenticator, and server roles.
  4. Separate employee, guest, and personally owned device onboarding through Cisco ISE identity and authorization policies matched to legitimate use.

Explanation

Correct Answer

D:

Separate employee, guest, and personally owned device onboarding through Cisco ISE identity and authorization policies matched to legitimate use. This control addresses the failure mechanism and narrows the enforcement boundary. Guest access and BYOD onboarding are authorization workflows, not a grant of permanent trusted access merely because a device connects to Wi-Fi. Confirm pre-change conditions using: Inspect identity source, portal flow, guest sponsor rules, endpoint registration, and assigned authorization profile. Situation: A contractor registers a personal tablet and receives the same internal access as a managed payroll workstation.

Incorrect Answers

A:

Enforce appropriate Cisco Duo MFA and device trust checks for protected applications, considering user role and device security status. This response applies to Cisco Duo multifactor and device trust policy, not the controlling requirement in this case. Multifactor authentication strengthens login assurance, while device trust and adaptive controls independently evaluate session risk. For this scenario, the targeted action is: Separate employee, guest, and personally owned device onboarding through Cisco ISE identity and authorization policies matched to legitimate use. Situation: A contractor registers a personal tablet and receives the same internal access as a managed payroll workstation.

B:

Combine device profiling evidence with authentication and posture to make appropriate Cisco ISE authorization decisions while acknowledging unknown device types. This response applies to Cisco ISE profiling and endpoint identity certainty, not the controlling requirement in this case. Network device profiling infers endpoint type from evidence; a recognized device category is not independent proof of user authorization or security posture. For this scenario, the targeted action is: Separate employee, guest, and personally owned device onboarding through Cisco ISE identity and authorization policies matched to legitimate use. Situation: A contractor registers a personal tablet and receives the same internal access as a managed payroll workstation.

C:

Configure network access device 802.1X to use Cisco ISE RADIUS decisions and verify supplicant, authenticator, and server roles. This response applies to 802.1X port-based access with Cisco ISE, not the controlling requirement in this case. In 802.1X the endpoint supplicant communicates through an authenticator to a back-end authentication server; access policy follows AAA results. For this scenario, the targeted action is: Separate employee, guest, and personally owned device onboarding through Cisco ISE identity and authorization policies matched to legitimate use. Situation: A contractor registers a personal tablet and receives the same internal access as a managed payroll workstation.

Question 635

A public booking API receives millions of near-identical requests while the web nodes show no suspicious new executables. Which observed result BEST confirms that the security requirement is met?

  1. New approved networks traverse the intended secured virtual tunnel without proliferating inconsistent policy selectors.
  2. A stolen integration token cannot read unrelated records and anomalous access triggers containment and credential replacement.
  3. The response mitigates the documented attack mechanism without mistaking a network flood for a local infected binary.
  4. One failed perimeter control does not provide unmonitored unrestricted access to sensitive workloads.

Explanation

Correct Answer

C:

The response mitigates the documented attack mechanism without mistaking a network flood for a local infected binary. This is an observable acceptance condition, rather than an assumption that enabling a feature alone proves security. A volumetric DDoS overwhelms service capacity whereas a Trojan executes on a host; discriminating evidence is required for targeted controls. Situation: A public booking API receives millions of near-identical requests while the web nodes show no suspicious new executables.

Incorrect Answers

A:

New approved networks traverse the intended secured virtual tunnel without proliferating inconsistent policy selectors. This outcome tests Route-based versus policy-based VPN design and is not sufficient proof of the stated requirement. Here the relevant validation is: The response mitigates the documented attack mechanism without mistaking a network flood for a local infected binary. Situation: A public booking API receives millions of near-identical requests while the web nodes show no suspicious new executables.

B:

A stolen integration token cannot read unrelated records and anomalous access triggers containment and credential replacement. This outcome tests Cloud API breach and lateral movement and is not sufficient proof of the stated requirement. Here the relevant validation is: The response mitigates the documented attack mechanism without mistaking a network flood for a local infected binary. Situation: A public booking API receives millions of near-identical requests while the web nodes show no suspicious new executables.

D:

One failed perimeter control does not provide unmonitored unrestricted access to sensitive workloads. This outcome tests Defense in depth and Cisco SAFE and is not sufficient proof of the stated requirement. Here the relevant validation is: The response mitigates the documented attack mechanism without mistaking a network flood for a local infected binary. Situation: A public booking API receives millions of near-identical requests while the web nodes show no suspicious new executables.

Question 636

A cloud developer publishes a service token in a public repository and unexpected database exports appear overnight. Which TWO complementary steps provide the most defensible remediation and its supporting assessment? Select TWO.

  1. Differentiate traffic-exhaustion attacks from host malware by inspecting network utilization, service saturation, and endpoint behavior before choosing containment.
  2. Inspect embedding source sets, package provenance, vector index tenant filters, model artifacts, and integrity-check history.
  3. Constrain compromised API credentials through scoped permissions, rotation, behavior alerts, and incident review rather than assuming encrypted transport prevents misuse.
  4. Known malicious destinations are contained and exposed identities are investigated rather than relying only on awareness posters.
  5. Review API audit calls, token audience and lifetime, privilege scope, abnormal exports, and linked cloud-resource access.

Explanation

Correct Answers

C:

Constrain compromised API credentials through scoped permissions, rotation, behavior alerts, and incident review rather than assuming encrypted transport prevents misuse. This control addresses the failure mechanism and narrows the enforcement boundary. Encryption in transit protects a channel but does not limit an authorized-looking API request carrying a stolen bearer token. Confirm pre-change conditions using: Review API audit calls, token audience and lifetime, privilege scope, abnormal exports, and linked cloud-resource access. This is the implementation portion of the complementary pair. Situation: A cloud developer publishes a service token in a public repository and unexpected database exports appear overnight.

E:

Review API audit calls, token audience and lifetime, privilege scope, abnormal exports, and linked cloud-resource access. This checks the relevant condition before an engineer modifies production access or detection behavior. Encryption in transit protects a channel but does not limit an authorized-looking API request carrying a stolen bearer token. The controlled response would be: Constrain compromised API credentials through scoped permissions, rotation, behavior alerts, and incident review rather than assuming encrypted transport prevents misuse. This supplies the diagnostic evidence needed for the complementary action. Situation: A cloud developer publishes a service token in a public repository and unexpected database exports appear overnight.

Incorrect Answers

A:

Differentiate traffic-exhaustion attacks from host malware by inspecting network utilization, service saturation, and endpoint behavior before choosing containment. This step could matter for DDoS versus endpoint malware diagnosis but is not part of the required complementary pair for this case. The paired steps are: Constrain compromised API credentials through scoped permissions, rotation, behavior alerts, and incident review rather than assuming encrypted transport prevents misuse. and Review API audit calls, token audience and lifetime, privilege scope, abnormal exports, and linked cloud-resource access. Situation: A cloud developer publishes a service token in a public repository and unexpected database exports appear overnight.

B:

Inspect embedding source sets, package provenance, vector index tenant filters, model artifacts, and integrity-check history. This step could matter for Embedding and model supply chain risk but is not part of the required complementary pair for this case. The paired steps are: Constrain compromised API credentials through scoped permissions, rotation, behavior alerts, and incident review rather than assuming encrypted transport prevents misuse. and Review API audit calls, token audience and lifetime, privilege scope, abnormal exports, and linked cloud-resource access. Situation: A cloud developer publishes a service token in a public repository and unexpected database exports appear overnight.

D:

Known malicious destinations are contained and exposed identities are investigated rather than relying only on awareness posters. This step could matter for Phishing containment and domain verification but is not part of the required complementary pair for this case. The paired steps are: Constrain compromised API credentials through scoped permissions, rotation, behavior alerts, and incident review rather than assuming encrypted transport prevents misuse. and Review API audit calls, token audience and lifetime, privilege scope, abnormal exports, and linked cloud-resource access. Situation: A cloud developer publishes a service token in a public repository and unexpected database exports appear overnight.

Question 637

An AI incident assistant reads a wiki paragraph that orders it to upload secret firewall configuration to a public endpoint. Which Cisco security control or operational response BEST addresses the stated need?

  1. Verify payment or access-change requests through an independently established channel and enforce dual approval for high-impact changes.
  2. Treat retrieved pages, documents, and tool responses as untrusted data and enforce tool authorization outside model-generated instructions.
  3. Use negotiated IKE/IPsec proposals with matching identities and selectors, and enable appropriate UDP encapsulation when NAT disrupts ESP carriage.
  4. Protect AI retrieval and model dependencies with integrity checks, source approval, access-filtered indexing, and controlled artifact promotion.

Explanation

Correct Answer

B:

Treat retrieved pages, documents, and tool responses as untrusted data and enforce tool authorization outside model-generated instructions. This control addresses the failure mechanism and narrows the enforcement boundary. Prompt injection occurs when lower-trust content is promoted to instruction authority; blocking unsafe tool effects requires enforcement beyond prompt wording. Confirm pre-change conditions using: Inspect source provenance, attempted instruction overrides, allowed tool verbs, prompt isolation, and server-side authorization results. Situation: An AI incident assistant reads a wiki paragraph that orders it to upload secret firewall configuration to a public endpoint.

Incorrect Answers

A:

Verify payment or access-change requests through an independently established channel and enforce dual approval for high-impact changes. This response applies to Business email compromise verification, not the controlling requirement in this case. A convincing display name or reply chain does not prove a sender can authorize sensitive financial and access changes. For this scenario, the targeted action is: Treat retrieved pages, documents, and tool responses as untrusted data and enforce tool authorization outside model-generated instructions. Situation: An AI incident assistant reads a wiki paragraph that orders it to upload secret firewall configuration to a public endpoint.

C:

Use negotiated IKE/IPsec proposals with matching identities and selectors, and enable appropriate UDP encapsulation when NAT disrupts ESP carriage. This response applies to IPsec IKE and NAT traversal, not the controlling requirement in this case. NAT traversal commonly encapsulates ESP over UDP 4500; a successful IKE handshake alone does not prove data-plane IPsec traffic passes. For this scenario, the targeted action is: Treat retrieved pages, documents, and tool responses as untrusted data and enforce tool authorization outside model-generated instructions. Situation: An AI incident assistant reads a wiki paragraph that orders it to upload secret firewall configuration to a public endpoint.

D:

Protect AI retrieval and model dependencies with integrity checks, source approval, access-filtered indexing, and controlled artifact promotion. This response applies to Embedding and model supply chain risk, not the controlling requirement in this case. A vector store can surface semantically similar but unauthorized or poisoned content; relevance scores are not authorization proof. For this scenario, the targeted action is: Treat retrieved pages, documents, and tool responses as untrusted data and enforce tool authorization outside model-generated instructions. Situation: An AI incident assistant reads a wiki paragraph that orders it to upload secret firewall configuration to a public endpoint.

Question 638

A remote laptop connects through a VPN profile that unintentionally routes sensitive management traffic outside enterprise inspection. Which TWO complementary steps provide the most defensible remediation and its supporting assessment? Select TWO.

  1. An authenticated unmanaged laptop is denied restricted data despite being on the corporate Wi-Fi, while approved sessions stay scoped.
  2. Protect remote workers with supported Cisco Secure Client VPN authentication, endpoint posture, split-routing policy, and controlled profile distribution.
  3. Inspect client connection logs, authentication flow, posture result, assigned routes, certificate policy, and headend access control.
  4. Choose route-based IPsec tunnels when dynamic routed topologies need predictable overlay interfaces and matched security policies.
  5. Inspect browser rendering contexts, state-changing HTTP endpoints, session cookie attributes, and request verification tokens.

Explanation

Correct Answers

B:

Protect remote workers with supported Cisco Secure Client VPN authentication, endpoint posture, split-routing policy, and controlled profile distribution. This control addresses the failure mechanism and narrows the enforcement boundary. Remote access VPN authenticates a user or device and creates protected transport; reachability still depends on routes, authorizations, and posture. Confirm pre-change conditions using: Inspect client connection logs, authentication flow, posture result, assigned routes, certificate policy, and headend access control. This is the implementation portion of the complementary pair. Situation: A remote laptop connects through a VPN profile that unintentionally routes sensitive management traffic outside enterprise inspection.

C:

Inspect client connection logs, authentication flow, posture result, assigned routes, certificate policy, and headend access control. This checks the relevant condition before an engineer modifies production access or detection behavior. Remote access VPN authenticates a user or device and creates protected transport; reachability still depends on routes, authorizations, and posture. The controlled response would be: Protect remote workers with supported Cisco Secure Client VPN authentication, endpoint posture, split-routing policy, and controlled profile distribution. This supplies the diagnostic evidence needed for the complementary action. Situation: A remote laptop connects through a VPN profile that unintentionally routes sensitive management traffic outside enterprise inspection.

Incorrect Answers

A:

An authenticated unmanaged laptop is denied restricted data despite being on the corporate Wi-Fi, while approved sessions stay scoped. This step could matter for Zero trust continuous authorization but is not part of the required complementary pair for this case. The paired steps are: Protect remote workers with supported Cisco Secure Client VPN authentication, endpoint posture, split-routing policy, and controlled profile distribution. and Inspect client connection logs, authentication flow, posture result, assigned routes, certificate policy, and headend access control. Situation: A remote laptop connects through a VPN profile that unintentionally routes sensitive management traffic outside enterprise inspection.

D:

Choose route-based IPsec tunnels when dynamic routed topologies need predictable overlay interfaces and matched security policies. This step could matter for Route-based versus policy-based VPN design but is not part of the required complementary pair for this case. The paired steps are: Protect remote workers with supported Cisco Secure Client VPN authentication, endpoint posture, split-routing policy, and controlled profile distribution. and Inspect client connection logs, authentication flow, posture result, assigned routes, certificate policy, and headend access control. Situation: A remote laptop connects through a VPN profile that unintentionally routes sensitive management traffic outside enterprise inspection.

E:

Inspect browser rendering contexts, state-changing HTTP endpoints, session cookie attributes, and request verification tokens. This step could matter for Web injection and request forgery but is not part of the required complementary pair for this case. The paired steps are: Protect remote workers with supported Cisco Secure Client VPN authentication, endpoint posture, split-routing policy, and controlled profile distribution. and Inspect client connection logs, authentication flow, posture result, assigned routes, certificate policy, and headend access control. Situation: A remote laptop connects through a VPN profile that unintentionally routes sensitive management traffic outside enterprise inspection.

Question 639

A security investigation finds that a service principal created new access keys but no audit trail links the change to its identity. Which Cisco security control or operational response BEST addresses the stated need?

  1. Combine dependency, container, and code security checks with change approval and deployment rollback across a DevSecOps pipeline.
  2. Document which security tasks belong to the provider versus the customer at each IaaS, PaaS, and SaaS layer and assign accountable owners.
  3. Restrict cloud roles to necessary actions and resources, require strong identity controls, and log administrative changes independent of workload configuration.
  4. Model workload dependencies and use policy-based application segmentation for least-privilege east-west communication with Cisco Secure Workload.

Explanation

Correct Answer

C:

Restrict cloud roles to necessary actions and resources, require strong identity controls, and log administrative changes independent of workload configuration. This control addresses the failure mechanism and narrows the enforcement boundary. Cloud privilege is an enforceable API control; encrypting data at rest does not prevent an overprivileged identity from invoking destructive actions. Confirm pre-change conditions using: Inspect IAM bindings, service identity usage, key rotation records, cross-account trust, and cloud audit event delivery. Situation: A security investigation finds that a service principal created new access keys but no audit trail links the change to its identity.

Incorrect Answers

A:

Combine dependency, container, and code security checks with change approval and deployment rollback across a DevSecOps pipeline. This response applies to CI CD container and application security lifecycle, not the controlling requirement in this case. DevSecOps embeds security early in delivery while preserving trusted runtime controls; scanning after production is not an adequate release gate. For this scenario, the targeted action is: Restrict cloud roles to necessary actions and resources, require strong identity controls, and log administrative changes independent of workload configuration. Situation: A security investigation finds that a service principal created new access keys but no audit trail links the change to its identity.

B:

Document which security tasks belong to the provider versus the customer at each IaaS, PaaS, and SaaS layer and assign accountable owners. This response applies to Cloud provider customer responsibility map, not the controlling requirement in this case. Cloud providers secure their portion of the stack, but moving an application to SaaS does not eliminate the customer's identity and data obligations. For this scenario, the targeted action is: Restrict cloud roles to necessary actions and resources, require strong identity controls, and log administrative changes independent of workload configuration. Situation: A security investigation finds that a service principal created new access keys but no audit trail links the change to its identity.

D:

Model workload dependencies and use policy-based application segmentation for least-privilege east-west communication with Cisco Secure Workload. This response applies to Cisco Secure Workload microsegmentation, not the controlling requirement in this case. Workload microsegmentation controls internal communications based on application context; it complements rather than replaces internet-facing perimeter security. For this scenario, the targeted action is: Restrict cloud roles to necessary actions and resources, require strong identity controls, and log administrative changes independent of workload configuration. Situation: A security investigation finds that a service principal created new access keys but no audit trail links the change to its identity.

Question 640

A tunnel dashboard shows connected but encrypt counters rise while decrypt counters remain zero. Which Cisco security control or operational response BEST addresses the stated need?

  1. Trace FTD VPN encryption/decryption counters, routes, NAT exemptions, and ACL matching when IKE is up but applications fail.
  2. Trace RADIUS network-access request and decision paths to isolate credential, shared secret, policy, or reachability failures.
  3. Configure FTD site-to-site VPN using compatible peer parameters, network selectors, identities, and routing/access rules, then verify both tunnel phases.
  4. Diagnose VPN setup failures in phase order by comparing peer reachability, authentication identities, and mutually supported IKE and IPsec proposals.

Explanation

Correct Answer

A:

Trace FTD VPN encryption/decryption counters, routes, NAT exemptions, and ACL matching when IKE is up but applications fail. This control addresses the failure mechanism and narrows the enforcement boundary. IKE-up status validates part of the control plane; the protected data plane requires matching routes, selectors, and NAT behavior. Confirm pre-change conditions using: Inspect bidirectional security association counters, packet traces, NAT policy, route selection, and remote selectors. Situation: A tunnel dashboard shows connected but encrypt counters rise while decrypt counters remain zero.

Incorrect Answers

B:

Trace RADIUS network-access request and decision paths to isolate credential, shared secret, policy, or reachability failures. This response applies to RADIUS network access troubleshooting, not the controlling requirement in this case. RADIUS typically supports network access control and policy attributes; network reachability, policy, and EAP trust must be checked independently. For this scenario, the targeted action is: Trace FTD VPN encryption/decryption counters, routes, NAT exemptions, and ACL matching when IKE is up but applications fail. Situation: A tunnel dashboard shows connected but encrypt counters rise while decrypt counters remain zero.

C:

Configure FTD site-to-site VPN using compatible peer parameters, network selectors, identities, and routing/access rules, then verify both tunnel phases. This response applies to FTD site-to-site VPN crypto policy, not the controlling requirement in this case. Successful VPN peer authentication does not prove application forwarding; selectors, route tables, NAT, and access policies also govern data traffic. For this scenario, the targeted action is: Trace FTD VPN encryption/decryption counters, routes, NAT exemptions, and ACL matching when IKE is up but applications fail. Situation: A tunnel dashboard shows connected but encrypt counters rise while decrypt counters remain zero.

D:

Diagnose VPN setup failures in phase order by comparing peer reachability, authentication identities, and mutually supported IKE and IPsec proposals. This response applies to FTD IKE negotiation failure isolation, not the controlling requirement in this case. Tunnel establishment progresses through distinct authentication and negotiation stages; changing unrelated firewall rules cannot fix mismatched proposals.
