Question 440

A help desk sees repeated login attempts against a dormant account followed by a successful password-only sign-in. Which TWO complementary steps provide the most defensible remediation and its supporting assessment? Select TWO.

  1. Inspect embedding source sets, package provenance, vector index tenant filters, model artifacts, and integrity-check history.
  2. Protected traffic crosses the tunnel with authenticated peers and encrypted data even behind the intended NAT device.
  3. Require phishing-resistant multifactor sign-in for sensitive accounts and investigate unusual authentication patterns before accepting credentials as trusted.
  4. Differentiate traffic-exhaustion attacks from host malware by inspecting network utilization, service saturation, and endpoint behavior before choosing containment.
  5. Inspect sender and destination mismatch, sign-in geography, authentication strength, new device enrollment, and user-reported prompts.

Explanation

Correct Answers

C:

Require phishing-resistant multifactor sign-in for sensitive accounts and investigate unusual authentication patterns before accepting credentials as trusted. This control addresses the failure mechanism and narrows the enforcement boundary. Phishing harvests authentication material; contextual verification and phishing-resistant authenticators reduce credential replay risk without proving all messages are safe. Confirm pre-change conditions using: Inspect sender and destination mismatch, sign-in geography, authentication strength, new device enrollment, and user-reported prompts. This is the implementation portion of the complementary pair. Situation: A help desk sees repeated login attempts against a dormant account followed by a successful password-only sign-in.

E:

Inspect sender and destination mismatch, sign-in geography, authentication strength, new device enrollment, and user-reported prompts. This checks the relevant condition before an engineer modifies production access or detection behavior. Phishing harvests authentication material; contextual verification and phishing-resistant authenticators reduce credential replay risk without proving all messages are safe. The controlled response would be: Require phishing-resistant multifactor sign-in for sensitive accounts and investigate unusual authentication patterns before accepting credentials as trusted. This supplies the diagnostic evidence needed for the complementary action. Situation: A help desk sees repeated login attempts against a dormant account followed by a successful password-only sign-in.

Incorrect Answers

A:

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: Require phishing-resistant multifactor sign-in for sensitive accounts and investigate unusual authentication patterns before accepting credentials as trusted. and Inspect sender and destination mismatch, sign-in geography, authentication strength, new device enrollment, and user-reported prompts. Situation: A help desk sees repeated login attempts against a dormant account followed by a successful password-only sign-in.

B:

Protected traffic crosses the tunnel with authenticated peers and encrypted data even behind the intended NAT device. This step could matter for IPsec IKE and NAT traversal but is not part of the required complementary pair for this case. The paired steps are: Require phishing-resistant multifactor sign-in for sensitive accounts and investigate unusual authentication patterns before accepting credentials as trusted. and Inspect sender and destination mismatch, sign-in geography, authentication strength, new device enrollment, and user-reported prompts. Situation: A help desk sees repeated login attempts against a dormant account followed by a successful password-only sign-in.

D:

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: Require phishing-resistant multifactor sign-in for sensitive accounts and investigate unusual authentication patterns before accepting credentials as trusted. and Inspect sender and destination mismatch, sign-in geography, authentication strength, new device enrollment, and user-reported prompts. Situation: A help desk sees repeated login attempts against a dormant account followed by a successful password-only sign-in.

Question 441

A project moves a workload to another region but its customer-managed key policy permits only the original service identity. Which Cisco security control or operational response BEST addresses the stated need?

  1. Secure cloud workloads and data with appropriate encryption, managed key access, and explicit ownership of secret rotation and runtime use.
  2. Document which security tasks belong to the provider versus the customer at each IaaS, PaaS, and SaaS layer and assign accountable owners.
  3. Use Cisco Multicloud Defense concepts to define controlled ingress, egress, and workload traffic inspection across supported cloud networks.
  4. Combine dependency, container, and code security checks with change approval and deployment rollback across a DevSecOps pipeline.

Explanation

Correct Answer

A:

Secure cloud workloads and data with appropriate encryption, managed key access, and explicit ownership of secret rotation and runtime use. This control addresses the failure mechanism and narrows the enforcement boundary. Encryption protects data against unauthorized reading but does not substitute for IAM; key lifecycle management and backups require explicit ownership. Confirm pre-change conditions using: Inspect storage encryption policy, customer-managed key dependencies, rotation schedule, secret locations, and access logs. Situation: A project moves a workload to another region but its customer-managed key policy permits only the original service identity.

Incorrect Answers

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: Secure cloud workloads and data with appropriate encryption, managed key access, and explicit ownership of secret rotation and runtime use. Situation: A project moves a workload to another region but its customer-managed key policy permits only the original service identity.

C:

Use Cisco Multicloud Defense concepts to define controlled ingress, egress, and workload traffic inspection across supported cloud networks. This response applies to Cisco Multicloud Defense traffic policy, not the controlling requirement in this case. A cloud traffic security service can provide coordinated policy, but routes and supported cloud connectivity determine which packets it actually sees. For this scenario, the targeted action is: Secure cloud workloads and data with appropriate encryption, managed key access, and explicit ownership of secret rotation and runtime use. Situation: A project moves a workload to another region but its customer-managed key policy permits only the original service identity.

D:

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: Secure cloud workloads and data with appropriate encryption, managed key access, and explicit ownership of secret rotation and runtime use. Situation: A project moves a workload to another region but its customer-managed key policy permits only the original service identity.

Question 442

An internal host transmits unusually high byte volumes to an unfamiliar external address but IDS signatures remain silent. Which Cisco security control or operational response BEST addresses the stated need?

  1. Use TACACS+ to centralize device administrator identity and command authorization with accountable audit trails.
  2. Collect and analyze flow-level metadata to identify communication patterns and suspicious volume while acknowledging payload visibility limits.
  3. Forward security event logs over approved protected transport and synchronize clocks for reliable multi-device incident reconstruction.
  4. Enable DHCP snooping on the supported switch VLANs and trust only intended DHCP-server-facing interfaces.

Explanation

Correct Answer

B:

Collect and analyze flow-level metadata to identify communication patterns and suspicious volume while acknowledging payload visibility limits. This control addresses the failure mechanism and narrows the enforcement boundary. Flow telemetry summarizes communicating endpoints and counters; packet payload inspection requires different data sources. Confirm pre-change conditions using: Inspect source/destination tuples, flow duration, byte counts, exporters, collector receipt, and sampling configuration. Situation: An internal host transmits unusually high byte volumes to an unfamiliar external address but IDS signatures remain silent.

Incorrect Answers

A:

Use TACACS+ to centralize device administrator identity and command authorization with accountable audit trails. This response applies to TACACS+ administration authorization, not the controlling requirement in this case. TACACS+ commonly separates authentication, authorization, and accounting for network device administration; user authentication alone does not grant every command. For this scenario, the targeted action is: Collect and analyze flow-level metadata to identify communication patterns and suspicious volume while acknowledging payload visibility limits. Situation: An internal host transmits unusually high byte volumes to an unfamiliar external address but IDS signatures remain silent.

C:

Forward security event logs over approved protected transport and synchronize clocks for reliable multi-device incident reconstruction. This response applies to Secure syslog and timestamp correlation, not the controlling requirement in this case. Central logging loses forensic value when clocks disagree or records are dropped; authenticated time and secure logging improve evidence quality. For this scenario, the targeted action is: Collect and analyze flow-level metadata to identify communication patterns and suspicious volume while acknowledging payload visibility limits. Situation: An internal host transmits unusually high byte volumes to an unfamiliar external address but IDS signatures remain silent.

D:

Enable DHCP snooping on the supported switch VLANs and trust only intended DHCP-server-facing interfaces. This response applies to DHCP snooping trust and rogue server control, not the controlling requirement in this case. DHCP snooping distinguishes trusted DHCP infrastructure from untrusted access ports and creates bindings useful for other Layer 2 controls. For this scenario, the targeted action is: Collect and analyze flow-level metadata to identify communication patterns and suspicious volume while acknowledging payload visibility limits. Situation: An internal host transmits unusually high byte volumes to an unfamiliar external address but IDS signatures remain silent.

Question 443

A regional network grows from two static subnets to dozens and wants dynamic route convergence over encrypted links. Which Cisco security control or operational response BEST addresses the stated need?

  1. Choose route-based IPsec tunnels when dynamic routed topologies need predictable overlay interfaces and matched security policies.
  2. Require phishing-resistant multifactor sign-in for sensitive accounts and investigate unusual authentication patterns before accepting credentials as trusted.
  3. Protect remote workers with supported Cisco Secure Client VPN authentication, endpoint posture, split-routing policy, and controlled profile distribution.
  4. Triage software vulnerabilities using version applicability, exploit exposure, available remediation, and business impact alongside published CVE and CVSS data.

Explanation

Correct Answer

A:

Choose route-based IPsec tunnels when dynamic routed topologies need predictable overlay interfaces and matched security policies. This control addresses the failure mechanism and narrows the enforcement boundary. Route-based VPN separates routing decisions from the cryptographic tunnel interface whereas policy-based VPN relies on matching crypto traffic definitions. Confirm pre-change conditions using: Inspect site prefix growth, routing requirements, traffic selectors, tunnel-interface support, and failover paths. Situation: A regional network grows from two static subnets to dozens and wants dynamic route convergence over encrypted links.

Incorrect Answers

B:

Require phishing-resistant multifactor sign-in for sensitive accounts and investigate unusual authentication patterns before accepting credentials as trusted. This response applies to Credential phishing and account takeover, not the controlling requirement in this case. Phishing harvests authentication material; contextual verification and phishing-resistant authenticators reduce credential replay risk without proving all messages are safe. For this scenario, the targeted action is: Choose route-based IPsec tunnels when dynamic routed topologies need predictable overlay interfaces and matched security policies. Situation: A regional network grows from two static subnets to dozens and wants dynamic route convergence over encrypted links.

C:

Protect remote workers with supported Cisco Secure Client VPN authentication, endpoint posture, split-routing policy, and controlled profile distribution. This response applies to Remote access VPN client controls, not the controlling requirement in this case. Remote access VPN authenticates a user or device and creates protected transport; reachability still depends on routes, authorizations, and posture. For this scenario, the targeted action is: Choose route-based IPsec tunnels when dynamic routed topologies need predictable overlay interfaces and matched security policies. Situation: A regional network grows from two static subnets to dozens and wants dynamic route convergence over encrypted links.

D:

Triage software vulnerabilities using version applicability, exploit exposure, available remediation, and business impact alongside published CVE and CVSS data. This response applies to CVE and CVSS vulnerability prioritization, not the controlling requirement in this case. A CVE identifies a disclosed issue and CVSS summarizes severity characteristics; neither alone proves exposure or exploitation of a particular asset. For this scenario, the targeted action is: Choose route-based IPsec tunnels when dynamic routed topologies need predictable overlay interfaces and matched security policies. Situation: A regional network grows from two static subnets to dozens and wants dynamic route convergence over encrypted links.

Question 444

A finance clerk receives an email impersonating a director with a no-attachment request to update bank details. Which TWO complementary steps provide the most defensible remediation and its supporting assessment? Select TWO.

  1. A noncompliant device receives remediation access but cannot reach restricted corporate services until reevaluated.
  2. Inspect prevention rules, process telemetry, behavioral detection coverage, isolation actions, and response history.
  3. Inspect sender authentication, impersonation indications, inbound/outbound message direction, detection verdict, and remediation authorization.
  4. Choose supported Email Threat Defense supplementary mailbox visibility or inline gateway enforcement according to platform and pre-delivery requirements.
  5. Configure Cisco Secure Email Threat Defense to detect or remediate phishing and business email compromise using appropriate supported integration and policy.

Explanation

Correct Answers

C:

Inspect sender authentication, impersonation indications, inbound/outbound message direction, detection verdict, and remediation authorization. This checks the relevant condition before an engineer modifies production access or detection behavior. Email Threat Defense uses message and behavioral context; an authenticated sender domain or clean attachment does not prove a message is safe. The controlled response would be: Configure Cisco Secure Email Threat Defense to detect or remediate phishing and business email compromise using appropriate supported integration and policy. This supplies the diagnostic evidence needed for the complementary action. Situation: A finance clerk receives an email impersonating a director with a no-attachment request to update bank details.

E:

Configure Cisco Secure Email Threat Defense to detect or remediate phishing and business email compromise using appropriate supported integration and policy. This control addresses the failure mechanism and narrows the enforcement boundary. Email Threat Defense uses message and behavioral context; an authenticated sender domain or clean attachment does not prove a message is safe. Confirm pre-change conditions using: Inspect sender authentication, impersonation indications, inbound/outbound message direction, detection verdict, and remediation authorization. This is the implementation portion of the complementary pair. Situation: A finance clerk receives an email impersonating a director with a no-attachment request to update bank details.

Incorrect Answers

A:

A noncompliant device receives remediation access but cannot reach restricted corporate services until reevaluated. This step could matter for Posture check before network access but is not part of the required complementary pair for this case. The paired steps are: Configure Cisco Secure Email Threat Defense to detect or remediate phishing and business email compromise using appropriate supported integration and policy. and Inspect sender authentication, impersonation indications, inbound/outbound message direction, detection verdict, and remediation authorization. Situation: A finance clerk receives an email impersonating a director with a no-attachment request to update bank details.

B:

Inspect prevention rules, process telemetry, behavioral detection coverage, isolation actions, and response history. This step could matter for Endpoint protection versus detection response but is not part of the required complementary pair for this case. The paired steps are: Configure Cisco Secure Email Threat Defense to detect or remediate phishing and business email compromise using appropriate supported integration and policy. and Inspect sender authentication, impersonation indications, inbound/outbound message direction, detection verdict, and remediation authorization. Situation: A finance clerk receives an email impersonating a director with a no-attachment request to update bank details.

D:

Choose supported Email Threat Defense supplementary mailbox visibility or inline gateway enforcement according to platform and pre-delivery requirements. This step could matter for Email Threat Defense deployment mode selection but is not part of the required complementary pair for this case. The paired steps are: Configure Cisco Secure Email Threat Defense to detect or remediate phishing and business email compromise using appropriate supported integration and policy. and Inspect sender authentication, impersonation indications, inbound/outbound message direction, detection verdict, and remediation authorization. Situation: A finance clerk receives an email impersonating a director with a no-attachment request to update bank details.

Question 445

A cloud firewall dashboard shows a successful rule draft but deployment state on one offline appliance remains unverified. Which TWO complementary steps provide the most defensible remediation and its supporting assessment? Select TWO.

  1. Choose centralized multi-device policy management for fleets while preserving appropriate emergency access and approval workflows.
  2. Assess Cisco Security Cloud Control against on-prem management requirements, identity controls, connectivity, and approved cloud operations.
  3. Inspect supported device inventory, tenant enrollment, API roles, internet management path, change evidence, and local fallback.
  4. Inspect peer public addresses, IKE/IPsec proposals, NAT treatment, interesting traffic, and security association counters.
  5. An unauthorized small switch cannot flood excessive MAC identities or form an unintended Layer 2 loop without detection.

Explanation

Correct Answers

B:

Assess Cisco Security Cloud Control against on-prem management requirements, identity controls, connectivity, and approved cloud operations. This control addresses the failure mechanism and narrows the enforcement boundary. Cloud-managed network policy still requires per-device compatibility, secure enrollment, change governance, and management connectivity. Confirm pre-change conditions using: Inspect supported device inventory, tenant enrollment, API roles, internet management path, change evidence, and local fallback. This is the implementation portion of the complementary pair. Situation: A cloud firewall dashboard shows a successful rule draft but deployment state on one offline appliance remains unverified.

C:

Question 446

A finance laptop uploads gigabytes of customer reports to a personal cloud drive after hours. Which TWO complementary steps provide the most defensible remediation and its supporting assessment? Select TWO.

  1. Correlated suspicious activity creates a reviewable incident and only authorized containment actions execute under tested automation.
  2. Identify suspicious DNS-based data movement using query entropy, length, volume, domain ownership, and endpoint context before containment.
  3. Inspect flow byte asymmetry, SaaS tenant, DLP events, process initiator, upload time, and user job role.
  4. Inspect detection search logic, sourcetype fields, incident assignment, playbook permissions, and result audit trail.
  5. Correlate unusual encrypted uploads and sanctioned cloud-service use with identity, DLP, destination, and endpoint telemetry.

Explanation

Correct Answers

C:

Inspect flow byte asymmetry, SaaS tenant, DLP events, process initiator, upload time, and user job role. This checks the relevant condition before an engineer modifies production access or detection behavior. HTTPS encryption does not prove the destination or data transfer is authorized; flow, SaaS policy, and endpoint context can reveal risk without blindly decrypting all traffic. The controlled response would be: Correlate unusual encrypted uploads and sanctioned cloud-service use with identity, DLP, destination, and endpoint telemetry. This supplies the diagnostic evidence needed for the complementary action. Situation: A finance laptop uploads gigabytes of customer reports to a personal cloud drive after hours.

E:

Correlate unusual encrypted uploads and sanctioned cloud-service use with identity, DLP, destination, and endpoint telemetry. This control addresses the failure mechanism and narrows the enforcement boundary. HTTPS encryption does not prove the destination or data transfer is authorized; flow, SaaS policy, and endpoint context can reveal risk without blindly decrypting all traffic. Confirm pre-change conditions using: Inspect flow byte asymmetry, SaaS tenant, DLP events, process initiator, upload time, and user job role. This is the implementation portion of the complementary pair. Situation: A finance laptop uploads gigabytes of customer reports to a personal cloud drive after hours.

Incorrect Answers

A:

Correlated suspicious activity creates a reviewable incident and only authorized containment actions execute under tested automation. This step could matter for SIEM and SOAR workflow distinction but is not part of the required complementary pair for this case. The paired steps are: Correlate unusual encrypted uploads and sanctioned cloud-service use with identity, DLP, destination, and endpoint telemetry. and Inspect flow byte asymmetry, SaaS tenant, DLP events, process initiator, upload time, and user job role. Situation: A finance laptop uploads gigabytes of customer reports to a personal cloud drive after hours.

B:

Identify suspicious DNS-based data movement using query entropy, length, volume, domain ownership, and endpoint context before containment. This step could matter for DNS tunneling exfiltration detection but is not part of the required complementary pair for this case. The paired steps are: Correlate unusual encrypted uploads and sanctioned cloud-service use with identity, DLP, destination, and endpoint telemetry. and Inspect flow byte asymmetry, SaaS tenant, DLP events, process initiator, upload time, and user job role. Situation: A finance laptop uploads gigabytes of customer reports to a personal cloud drive after hours.

D:

Inspect detection search logic, sourcetype fields, incident assignment, playbook permissions, and result audit trail. This step could matter for Splunk event orchestration and response workflows but is not part of the required complementary pair for this case. The paired steps are: Correlate unusual encrypted uploads and sanctioned cloud-service use with identity, DLP, destination, and endpoint telemetry. and Inspect flow byte asymmetry, SaaS tenant, DLP events, process initiator, upload time, and user job role. Situation: A finance laptop uploads gigabytes of customer reports to a personal cloud drive after hours.

Question 447

A campus uses Security Group Tags but a trunk path drops tags, causing inconsistent access policy results. Before changing security policy, what evidence should the engineer examine FIRST?

  1. Inspect endpoint identity assignments, VLAN membership, SGT propagation, trustsec matrix rules, and routed reachability.
  2. Review syslog destinations, transport security, facility and severity filters, log loss, NTP synchronization, and collector permissions.
  3. Inspect DHCP snooping bindings or static ARP ACLs, trusted links, validation drops, and legitimate static IP exceptions.
  4. Review fail-open or fail-closed expectations, high-availability topology, interface mode, IPS rule state, and packet counters.

Explanation

Correct Answer

A:

Inspect endpoint identity assignments, VLAN membership, SGT propagation, trustsec matrix rules, and routed reachability. This checks the relevant condition before an engineer modifies production access or detection behavior. VLANs group Layer 2 broadcast domains; SGT-based policies can follow endpoint identity across supported network paths independent of a particular subnet. The controlled response would be: Separate groups with VLAN boundaries and apply identity or context-based SGT policy where infrastructure supports scalable group enforcement. Situation: A campus uses Security Group Tags but a trunk path drops tags, causing inconsistent access policy results.

Incorrect Answers

B:

Review syslog destinations, transport security, facility and severity filters, log loss, NTP synchronization, and collector permissions. This evidence addresses Secure syslog and timestamp correlation; it would not establish the primary issue here. The diagnostic evidence needed for this scenario is: Inspect endpoint identity assignments, VLAN membership, SGT propagation, trustsec matrix rules, and routed reachability. Situation: A campus uses Security Group Tags but a trunk path drops tags, causing inconsistent access policy results.

C:

Inspect DHCP snooping bindings or static ARP ACLs, trusted links, validation drops, and legitimate static IP exceptions. This evidence addresses Dynamic ARP inspection and spoofed gateway; it would not establish the primary issue here. The diagnostic evidence needed for this scenario is: Inspect endpoint identity assignments, VLAN membership, SGT propagation, trustsec matrix rules, and routed reachability. Situation: A campus uses Security Group Tags but a trunk path drops tags, causing inconsistent access policy results.

D:

Review fail-open or fail-closed expectations, high-availability topology, interface mode, IPS rule state, and packet counters. This evidence addresses Inline IPS availability and bypass behavior; it would not establish the primary issue here. The diagnostic evidence needed for this scenario is: Inspect endpoint identity assignments, VLAN membership, SGT propagation, trustsec matrix rules, and routed reachability. Situation: A campus uses Security Group Tags but a trunk path drops tags, causing inconsistent access policy results.

Question 448

A malware sample is allowed after an overly broad path exclusion was created for a trusted application. Before changing security policy, what evidence should the engineer examine FIRST?

  1. Inspect endpoint groups, policy assignment, connector state, disposition settings, exclusions, and event history.
  2. Inspect last posture evaluation time, policy change triggers, endpoint alert status, session authorization, and remediation evidence.
  3. Inspect original file hash, current cloud disposition, execution history, file trajectory, and response capability.
  4. Inspect email platform, API permissions, journaling architecture, allowed mail-flow changes, product entitlement, and required remediation actions.

Explanation

Correct Answer

A:

Inspect endpoint groups, policy assignment, connector state, disposition settings, exclusions, and event history. This checks the relevant condition before an engineer modifies production access or detection behavior. Endpoint policy efficacy depends on correct host enrollment, file disposition, behavior detection, and controlled exclusions. The controlled response would be: Configure Cisco Secure Endpoint policy groups, detection and blocking settings, and connector deployment aligned to host risk. Situation: A malware sample is allowed after an overly broad path exclusion was created for a trusted application.

Incorrect Answers

B:

Inspect last posture evaluation time, policy change triggers, endpoint alert status, session authorization, and remediation evidence. This evidence addresses Continuous endpoint trust and posture drift; it would not establish the primary issue here. The diagnostic evidence needed for this scenario is: Inspect endpoint groups, policy assignment, connector state, disposition settings, exclusions, and event history. Situation: A malware sample is allowed after an overly broad path exclusion was created for a trusted application.

C:

Inspect original file hash, current cloud disposition, execution history, file trajectory, and response capability. This evidence addresses Malware retrospective disposition response; it would not establish the primary issue here. The diagnostic evidence needed for this scenario is: Inspect endpoint groups, policy assignment, connector state, disposition settings, exclusions, and event history. Situation: A malware sample is allowed after an overly broad path exclusion was created for a trusted application.

D:

Inspect email platform, API permissions, journaling architecture, allowed mail-flow changes, product entitlement, and required remediation actions. This evidence addresses Email Threat Defense deployment mode selection; it would not establish the primary issue here. The diagnostic evidence needed for this scenario is: Inspect endpoint groups, policy assignment, connector state, disposition settings, exclusions, and event history. Situation: A malware sample is allowed after an overly broad path exclusion was created for a trusted application.

Question 449

A remote client encrypts traffic to a server but ignores an untrusted intermediate certificate warning. Which Cisco security control or operational response BEST addresses the stated need?

  1. Prevent SQL injection by separating untrusted field values from query structure using parameter binding and constrained database privileges.
  2. Validate peer identity with a trusted certificate chain, correct hostname, certificate validity, and appropriate TLS policy before exchanging sensitive data.
  3. Apply context-aware output encoding, anti-CSRF protections, and correct cookie controls at the relevant trust boundary.
  4. Use negotiated IKE/IPsec proposals with matching identities and selectors, and enable appropriate UDP encapsulation when NAT disrupts ESP carriage.

Explanation

Correct Answer

B:

Validate peer identity with a trusted certificate chain, correct hostname, certificate validity, and appropriate TLS policy before exchanging sensitive data. This control addresses the failure mechanism and narrows the enforcement boundary. Encryption without authenticated identity does not rule out interception; certificates bind a public key to a verified name under a trust chain. Confirm pre-change conditions using: Inspect server certificate SAN, chain trust, expiry and revocation status, negotiated protocol, and handshake errors. Situation: A remote client encrypts traffic to a server but ignores an untrusted intermediate certificate warning.

Incorrect Answers

A:

Prevent SQL injection by separating untrusted field values from query structure using parameter binding and constrained database privileges. This response applies to SQL injection and parameterized queries, not the controlling requirement in this case. SQL injection exploits code/data confusion; input sanitization alone is weaker than parameterization plus least privilege. For this scenario, the targeted action is: Validate peer identity with a trusted certificate chain, correct hostname, certificate validity, and appropriate TLS policy before exchanging sensitive data. Situation: A remote client encrypts traffic to a server but ignores an untrusted intermediate certificate warning.

C:

Apply context-aware output encoding, anti-CSRF protections, and correct cookie controls at the relevant trust boundary. This response applies to Web injection and request forgery, not the controlling requirement in this case. XSS executes attacker-controlled browser code, while CSRF tricks an authenticated browser into submitting unintended operations; their mitigations differ. For this scenario, the targeted action is: Validate peer identity with a trusted certificate chain, correct hostname, certificate validity, and appropriate TLS policy before exchanging sensitive data. Situation: A remote client encrypts traffic to a server but ignores an untrusted intermediate certificate warning.

D:

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: Validate peer identity with a trusted certificate chain, correct hostname, certificate validity, and appropriate TLS policy before exchanging sensitive data. Situation: A remote client encrypts traffic to a server but ignores an untrusted intermediate certificate warning.

Question 450

An application compares file digests to detect changed images but assumes the digest itself hides the underlying content. Before changing security policy, what evidence should the engineer examine FIRST?

  1. Inspect protected data lifetimes, protocol suites, key sizes, certificate dependencies, crypto inventory, and approved algorithm policies.
  2. Inspect IKE proposal mismatches, pre-shared or certificate identity, UDP 500 or 4500 reachability, NAT detection, and phase negotiation logs.
  3. Inspect dynamic SQL construction, query logs, supplied payloads, database role privileges, and application input paths.
  4. Inspect site prefix growth, routing requirements, traffic selectors, tunnel-interface support, and failover paths.

Explanation

Correct Answer

A:

Inspect protected data lifetimes, protocol suites, key sizes, certificate dependencies, crypto inventory, and approved algorithm policies. This checks the relevant condition before an engineer modifies production access or detection behavior. A bare hash does not provide secrecy; post-quantum preparation requires crypto-agility planning rather than claiming traditional algorithms are already future-proof. The controlled response would be: Use cryptographic hashes for integrity, authenticated key exchange for confidentiality, and maintain a migration inventory for post-quantum risks. Situation: An application compares file digests to detect changed images but assumes the digest itself hides the underlying content.

Incorrect Answers

B:

Inspect IKE proposal mismatches, pre-shared or certificate identity, UDP 500 or 4500 reachability, NAT detection, and phase negotiation logs. This evidence addresses IPsec IKE and NAT traversal; it would not establish the primary issue here. The diagnostic evidence needed for this scenario is: Inspect protected data lifetimes, protocol suites, key sizes, certificate dependencies, crypto inventory, and approved algorithm policies. Situation: An application compares file digests to detect changed images but assumes the digest itself hides the underlying content.

C:

Inspect dynamic SQL construction, query logs, supplied payloads, database role privileges, and application input paths. This evidence addresses SQL injection and parameterized queries; it would not establish the primary issue here. The diagnostic evidence needed for this scenario is: Inspect protected data lifetimes, protocol suites, key sizes, certificate dependencies, crypto inventory, and approved algorithm policies. Situation: An application compares file digests to detect changed images but assumes the digest itself hides the underlying content.

D:

Inspect site prefix growth, routing requirements, traffic selectors, tunnel-interface support, and failover paths. This evidence addresses Route-based versus policy-based VPN design; it would not establish the primary issue here. The diagnostic evidence needed for this scenario is: Inspect protected data lifetimes, protocol suites, key sizes, certificate dependencies, crypto inventory, and approved algorithm policies. Situation: An application compares file digests to detect changed images but assumes the digest itself hides the underlying content.
