Question 570

A Duo SSO integration logs a successful sign-in but users are assigned incorrect access due to a stale group mapping. Which Cisco security control or operational response BEST addresses the stated need?

  1. Combine device profiling evidence with authentication and posture to make appropriate Cisco ISE authorization decisions while acknowledging unknown device types.
  2. Enforce appropriate Cisco Duo MFA and device trust checks for protected applications, considering user role and device security status.
  3. Use RADIUS Change of Authorization to trigger reauthentication or update access on an active network session when identity or posture changes.
  4. Use Cisco Duo SSO and Adaptive Access to apply policy based on user group, application sensitivity, location or risk, and device health where supported.

Explanation

Correct Answer

D:

Use Cisco Duo SSO and Adaptive Access to apply policy based on user group, application sensitivity, location or risk, and device health where supported. This control addresses the failure mechanism and narrows the enforcement boundary. Single sign-on simplifies authentication flow but does not mean every connected application should share identical authorization and risk policy. Confirm pre-change conditions using: Inspect SSO federation setup, conditional access rules, authenticator strength, location signals, and Duo activity logs. Situation: A Duo SSO integration logs a successful sign-in but users are assigned incorrect access due to a stale group mapping.

Incorrect Answers

A:

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: Use Cisco Duo SSO and Adaptive Access to apply policy based on user group, application sensitivity, location or risk, and device health where supported. Situation: A Duo SSO integration logs a successful sign-in but users are assigned incorrect access due to a stale group mapping.

B:

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: Use Cisco Duo SSO and Adaptive Access to apply policy based on user group, application sensitivity, location or risk, and device health where supported. Situation: A Duo SSO integration logs a successful sign-in but users are assigned incorrect access due to a stale group mapping.

C:

Use RADIUS Change of Authorization to trigger reauthentication or update access on an active network session when identity or posture changes. This response applies to CoA session reauthorization by Cisco ISE, not the controlling requirement in this case. CoA allows an AAA policy server to request changes to an existing access session; it requires compatible network device settings and correct session matching. For this scenario, the targeted action is: Use Cisco Duo SSO and Adaptive Access to apply policy based on user group, application sensitivity, location or risk, and device health where supported. Situation: A Duo SSO integration logs a successful sign-in but users are assigned incorrect access due to a stale group mapping.

Question 571

A failed automation run repeats creation of a network object and inserts three redundant firewall rules. Which TWO complementary steps provide the most defensible remediation and its supporting assessment? Select TWO.

  1. Inspect browser rendering contexts, state-changing HTTP endpoints, session cookie attributes, and request verification tokens.
  2. Call security appliance APIs with scoped tokens, supported methods, validated payloads, and explicit handling of HTTP failures.
  3. Inspect existing policy objects, API conflict or retry responses, object identifiers, approvals, and rollback artifacts.
  4. An authenticated unmanaged laptop is denied restricted data despite being on the corporate Wi-Fi, while approved sessions stay scoped.
  5. Implement safe automation with pre-change state capture, idempotent desired configuration, audit records, and validation after deployment.

Explanation

Correct Answers

C:

Inspect existing policy objects, API conflict or retry responses, object identifiers, approvals, and rollback artifacts. This checks the relevant condition before an engineer modifies production access or detection behavior. Blind retries of security policy POST requests can create duplicate or contradictory rules; idempotency and change tracking protect consistency. The controlled response would be: Implement safe automation with pre-change state capture, idempotent desired configuration, audit records, and validation after deployment. This supplies the diagnostic evidence needed for the complementary action. Situation: A failed automation run repeats creation of a network object and inserts three redundant firewall rules.

E:

Implement safe automation with pre-change state capture, idempotent desired configuration, audit records, and validation after deployment. This control addresses the failure mechanism and narrows the enforcement boundary. Blind retries of security policy POST requests can create duplicate or contradictory rules; idempotency and change tracking protect consistency. Confirm pre-change conditions using: Inspect existing policy objects, API conflict or retry responses, object identifiers, approvals, and rollback artifacts. This is the implementation portion of the complementary pair. Situation: A failed automation run repeats creation of a network object and inserts three redundant firewall rules.

Incorrect Answers

A:

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: Implement safe automation with pre-change state capture, idempotent desired configuration, audit records, and validation after deployment. and Inspect existing policy objects, API conflict or retry responses, object identifiers, approvals, and rollback artifacts. Situation: A failed automation run repeats creation of a network object and inserts three redundant firewall rules.

B:

Call security appliance APIs with scoped tokens, supported methods, validated payloads, and explicit handling of HTTP failures. This step could matter for Authenticated security API requests but is not part of the required complementary pair for this case. The paired steps are: Implement safe automation with pre-change state capture, idempotent desired configuration, audit records, and validation after deployment. and Inspect existing policy objects, API conflict or retry responses, object identifiers, approvals, and rollback artifacts. Situation: A failed automation run repeats creation of a network object and inserts three redundant firewall rules.

D:

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: Implement safe automation with pre-change state capture, idempotent desired configuration, audit records, and validation after deployment. and Inspect existing policy objects, API conflict or retry responses, object identifiers, approvals, and rollback artifacts. Situation: A failed automation run repeats creation of a network object and inserts three redundant firewall rules.

Question 572

A cloud team changes encryption settings manually after apply and later code runs restore the insecure configuration. Which TWO complementary steps provide the most defensible remediation and its supporting assessment? Select TWO.

  1. Inspect Terraform or similar plan diff, policy-as-code results, source review, sensitive variable handling, and approver identity.
  2. Inspect supported kernel/runtime versions, telemetry capture points, performance overhead, event schemas, and control ownership.
  3. Require IaC templates to pass secrets, policy, and network exposure scanning before deployment and document authorized exceptions.
  4. Combine dependency, container, and code security checks with change approval and deployment rollback across a DevSecOps pipeline.
  5. A compromised workload identity cannot delete unrelated assets and changes are attributable to an approved actor.

Explanation

Correct Answers

A:

Inspect Terraform or similar plan diff, policy-as-code results, source review, sensitive variable handling, and approver identity. This checks the relevant condition before an engineer modifies production access or detection behavior. Infrastructure as Code makes misconfiguration reproducible; peer review and predeployment policy gates reduce repeated risky settings. The controlled response would be: Require IaC templates to pass secrets, policy, and network exposure scanning before deployment and document authorized exceptions. This supplies the diagnostic evidence needed for the complementary action. Situation: A cloud team changes encryption settings manually after apply and later code runs restore the insecure configuration.

C:

Require IaC templates to pass secrets, policy, and network exposure scanning before deployment and document authorized exceptions. This control addresses the failure mechanism and narrows the enforcement boundary. Infrastructure as Code makes misconfiguration reproducible; peer review and predeployment policy gates reduce repeated risky settings. Confirm pre-change conditions using: Inspect Terraform or similar plan diff, policy-as-code results, source review, sensitive variable handling, and approver identity. This is the implementation portion of the complementary pair. Situation: A cloud team changes encryption settings manually after apply and later code runs restore the insecure configuration.

Incorrect Answers

B:

Inspect supported kernel/runtime versions, telemetry capture points, performance overhead, event schemas, and control ownership. This step could matter for eBPF security telemetry scope but is not part of the required complementary pair for this case. The paired steps are: Require IaC templates to pass secrets, policy, and network exposure scanning before deployment and document authorized exceptions. and Inspect Terraform or similar plan diff, policy-as-code results, source review, sensitive variable handling, and approver identity. Situation: A cloud team changes encryption settings manually after apply and later code runs restore the insecure configuration.

D:

Combine dependency, container, and code security checks with change approval and deployment rollback across a DevSecOps pipeline. This step could matter for CI CD container and application security lifecycle but is not part of the required complementary pair for this case. The paired steps are: Require IaC templates to pass secrets, policy, and network exposure scanning before deployment and document authorized exceptions. and Inspect Terraform or similar plan diff, policy-as-code results, source review, sensitive variable handling, and approver identity. Situation: A cloud team changes encryption settings manually after apply and later code runs restore the insecure configuration.

E:

A compromised workload identity cannot delete unrelated assets and changes are attributable to an approved actor. This step could matter for Cloud IAM least privilege and logging but is not part of the required complementary pair for this case. The paired steps are: Require IaC templates to pass secrets, policy, and network exposure scanning before deployment and document authorized exceptions. and Inspect Terraform or similar plan diff, policy-as-code results, source review, sensitive variable handling, and approver identity. Situation: A cloud team changes encryption settings manually after apply and later code runs restore the insecure configuration.

Question 573

A container investigation needs to tie outbound connections to the Linux process that created them. Which observed result BEST confirms that the security requirement is met?

  1. Workload process-to-network events are attributable without destabilizing the monitored host or overstating enforcement abilities.
  2. A test cloud privilege escalation is detected with linked sign-in and API activity rather than isolated low-context alerts.
  3. A changed unsigned image or privileged unexpected workload is blocked from the approved deployment process.
  4. Required cloud audit events are searchable with accurate timestamps and identifiable source fields after ingestion.

Explanation

Correct Answer

A:

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: A container investigation needs to tie outbound connections to the Linux process that created them.

Incorrect Answers

B:

A test cloud privilege escalation is detected with linked sign-in and API activity rather than isolated low-context alerts. This outcome tests Splunk detection correlation across cloud feeds 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: A container investigation needs to tie outbound connections to the Linux process that created them.

C:

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: A container investigation needs to tie outbound connections to the Linux process that created them.

D:

Required cloud audit events are searchable with accurate timestamps and identifiable source fields after ingestion. This outcome tests Splunk cloud source onboarding 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: A container investigation needs to tie outbound connections to the Linux process that created them.

Question 574

Dynamic ARP inspection fails to validate an otherwise legitimate host because its snooping binding is missing. Which Cisco security control or operational response BEST addresses the stated need?

  1. Enable DHCP snooping on the supported switch VLANs and trust only intended DHCP-server-facing interfaces.
  2. Diagnose VPN setup failures in phase order by comparing peer reachability, authentication identities, and mutually supported IKE and IPsec proposals.
  3. Use Dynamic ARP Inspection with reliable IP-to-MAC bindings to reject forged ARP claims on untrusted access interfaces.
  4. Forward security event logs over approved protected transport and synchronize clocks for reliable multi-device incident reconstruction.

Explanation

Correct Answer

A:

Enable DHCP snooping on the supported switch VLANs and trust only intended DHCP-server-facing interfaces. This control addresses the failure mechanism and narrows the enforcement boundary. DHCP snooping distinguishes trusted DHCP infrastructure from untrusted access ports and creates bindings useful for other Layer 2 controls. Confirm pre-change conditions using: Inspect VLAN enablement, trusted port design, binding table entries, DHCP offer sources, and port limits. Situation: Dynamic ARP inspection fails to validate an otherwise legitimate host because its snooping binding is missing.

Incorrect Answers

B:

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. For this scenario, the targeted action is: Enable DHCP snooping on the supported switch VLANs and trust only intended DHCP-server-facing interfaces. Situation: Dynamic ARP inspection fails to validate an otherwise legitimate host because its snooping binding is missing.

C:

Use Dynamic ARP Inspection with reliable IP-to-MAC bindings to reject forged ARP claims on untrusted access interfaces. This response applies to Dynamic ARP inspection and spoofed gateway, not the controlling requirement in this case. DAI relies on trustworthy binding information; enabling inspection without handling static addressing can interrupt legitimate users. For this scenario, the targeted action is: Enable DHCP snooping on the supported switch VLANs and trust only intended DHCP-server-facing interfaces. Situation: Dynamic ARP inspection fails to validate an otherwise legitimate host because its snooping binding is missing.

D:

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: Enable DHCP snooping on the supported switch VLANs and trust only intended DHCP-server-facing interfaces. Situation: Dynamic ARP inspection fails to validate an otherwise legitimate host because its snooping binding is missing.

Question 575

A security team introduces multicloud traffic enforcement but forgets to verify return routing for a production application. 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. Correlate normalized cloud identity, network, and workload events in Splunk with scoped detections and validated false-positive behavior.
  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

C:

Use Cisco Multicloud Defense concepts to define controlled ingress, egress, and workload traffic inspection across supported cloud networks. This control addresses the failure mechanism and narrows the enforcement boundary. A cloud traffic security service can provide coordinated policy, but routes and supported cloud connectivity determine which packets it actually sees. Confirm pre-change conditions using: Inspect cloud route tables, network attachment paths, traffic direction, security policy, and supported deployment scope. Situation: A security team introduces multicloud traffic enforcement but forgets to verify return routing for a production application.

Incorrect Answers

A:

Secure cloud workloads and data with appropriate encryption, managed key access, and explicit ownership of secret rotation and runtime use. This response applies to Cloud application encryption and key responsibility, not the controlling requirement in this case. Encryption protects data against unauthorized reading but does not substitute for IAM; key lifecycle management and backups require explicit ownership. For this scenario, the targeted action is: Use Cisco Multicloud Defense concepts to define controlled ingress, egress, and workload traffic inspection across supported cloud networks. Situation: A security team introduces multicloud traffic enforcement but forgets to verify return routing for a production application.

B:

Correlate normalized cloud identity, network, and workload events in Splunk with scoped detections and validated false-positive behavior. This response applies to Splunk detection correlation across cloud feeds, not the controlling requirement in this case. A SIEM correlation rule depends on reliable field extraction and shared identity context; large event counts alone do not equal threat detection. For this scenario, the targeted action is: Use Cisco Multicloud Defense concepts to define controlled ingress, egress, and workload traffic inspection across supported cloud networks. Situation: A security team introduces multicloud traffic enforcement but forgets to verify return routing for a production application.

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: Use Cisco Multicloud Defense concepts to define controlled ingress, egress, and workload traffic inspection across supported cloud networks. Situation: A security team introduces multicloud traffic enforcement but forgets to verify return routing for a production application.

Question 576

A malware sample is allowed after an overly broad path exclusion was created for a trusted application. Which observed result BEST confirms that the security requirement is met?

  1. A controlled malicious test file is detected or blocked under the intended endpoint policy while approved software remains functional.
  2. High-impact active behavior receives response ahead of low-context historical detections, with reasons recorded.
  3. A confirmed legitimate application resumes operation while unrelated malicious activity remains detectable.
  4. A suspicious attachment receives a documented risk verdict supported by observed behavior without executing it on a production endpoint.

Explanation

Correct Answer

A:

A controlled malicious test file is detected or blocked under the intended endpoint policy while approved software remains functional. This is an observable acceptance condition, rather than an assumption that enabling a feature alone proves security. Endpoint policy efficacy depends on correct host enrollment, file disposition, behavior detection, and controlled exclusions. Situation: A malware sample is allowed after an overly broad path exclusion was created for a trusted application.

Incorrect Answers

B:

High-impact active behavior receives response ahead of low-context historical detections, with reasons recorded. This outcome tests Endpoint malware event prioritization and is not sufficient proof of the stated requirement. Here the relevant validation is: A controlled malicious test file is detected or blocked under the intended endpoint policy while approved software remains functional. Situation: A malware sample is allowed after an overly broad path exclusion was created for a trusted application.

C:

A confirmed legitimate application resumes operation while unrelated malicious activity remains detectable. This outcome tests Secure Endpoint response exclusions and policy safety and is not sufficient proof of the stated requirement. Here the relevant validation is: A controlled malicious test file is detected or blocked under the intended endpoint policy while approved software remains functional. Situation: A malware sample is allowed after an overly broad path exclusion was created for a trusted application.

D:

A suspicious attachment receives a documented risk verdict supported by observed behavior without executing it on a production endpoint. This outcome tests Cisco Secure Malware Analytics detonation evidence and is not sufficient proof of the stated requirement. Here the relevant validation is: A controlled malicious test file is detected or blocked under the intended endpoint policy while approved software remains functional. Situation: A malware sample is allowed after an overly broad path exclusion was created for a trusted application.

Question 577

A remote user passes MFA but has no business role requiring access to production database backups. Before changing security policy, what evidence should the engineer examine FIRST?

  1. Inspect site prefix growth, routing requirements, traffic selectors, tunnel-interface support, and failover paths.
  2. Inspect sign-in strength, device compliance, resource policy, segmentation, session risk, and reevaluation triggers.
  3. Review asset versions, affected component evidence, external reachability, exploit preconditions, compensating controls, and vendor advisories.
  4. Inspect IKE proposal mismatches, pre-shared or certificate identity, UDP 500 or 4500 reachability, NAT detection, and phase negotiation logs.

Explanation

Correct Answer

B:

Inspect sign-in strength, device compliance, resource policy, segmentation, session risk, and reevaluation triggers. This checks the relevant condition before an engineer modifies production access or detection behavior. Zero trust uses explicit verification and least-privilege access; being inside a perimeter is not sufficient proof of permission. The controlled response would be: Evaluate identity, device posture, resource context, and least privilege per session rather than granting broad trust by physical network location. Situation: A remote user passes MFA but has no business role requiring access to production database backups.

Incorrect Answers

A:

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 sign-in strength, device compliance, resource policy, segmentation, session risk, and reevaluation triggers. Situation: A remote user passes MFA but has no business role requiring access to production database backups.

C:

Review asset versions, affected component evidence, external reachability, exploit preconditions, compensating controls, and vendor advisories. This evidence addresses CVE and CVSS vulnerability prioritization; it would not establish the primary issue here. The diagnostic evidence needed for this scenario is: Inspect sign-in strength, device compliance, resource policy, segmentation, session risk, and reevaluation triggers. Situation: A remote user passes MFA but has no business role requiring access to production database backups.

D:

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 sign-in strength, device compliance, resource policy, segmentation, session risk, and reevaluation triggers. Situation: A remote user passes MFA but has no business role requiring access to production database backups.

Question 578

A branch user reports malware popups but the application is slow only during a major inbound traffic spike at the firewall. Before changing security policy, what evidence should the engineer examine FIRST?

  1. Inspect browser rendering contexts, state-changing HTTP endpoints, session cookie attributes, and request verification tokens.
  2. Inspect sender and destination mismatch, sign-in geography, authentication strength, new device enrollment, and user-reported prompts.
  3. Inspect IKE proposal mismatches, pre-shared or certificate identity, UDP 500 or 4500 reachability, NAT detection, and phase negotiation logs.
  4. Examine flow spikes, source distributions, server resource graphs, load-balancer logs, and endpoint execution telemetry.

Explanation

Correct Answer

D:

Examine flow spikes, source distributions, server resource graphs, load-balancer logs, and endpoint execution telemetry. This checks the relevant condition before an engineer modifies production access or detection behavior. A volumetric DDoS overwhelms service capacity whereas a Trojan executes on a host; discriminating evidence is required for targeted controls. The controlled response would be: Differentiate traffic-exhaustion attacks from host malware by inspecting network utilization, service saturation, and endpoint behavior before choosing containment. Situation: A branch user reports malware popups but the application is slow only during a major inbound traffic spike at the firewall.

Incorrect Answers

A:

Inspect browser rendering contexts, state-changing HTTP endpoints, session cookie attributes, and request verification tokens. This evidence addresses Web injection and request forgery; it would not establish the primary issue here. The diagnostic evidence needed for this scenario is: Examine flow spikes, source distributions, server resource graphs, load-balancer logs, and endpoint execution telemetry. Situation: A branch user reports malware popups but the application is slow only during a major inbound traffic spike at the firewall.

B:

Inspect sender and destination mismatch, sign-in geography, authentication strength, new device enrollment, and user-reported prompts. This evidence addresses Credential phishing and account takeover; it would not establish the primary issue here. The diagnostic evidence needed for this scenario is: Examine flow spikes, source distributions, server resource graphs, load-balancer logs, and endpoint execution telemetry. Situation: A branch user reports malware popups but the application is slow only during a major inbound traffic spike at the firewall.

C:

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: Examine flow spikes, source distributions, server resource graphs, load-balancer logs, and endpoint execution telemetry. Situation: A branch user reports malware popups but the application is slow only during a major inbound traffic spike at the firewall.

Question 579

A help desk restores endpoint compliance and wants Cisco ISE to reauthorize the current session automatically. Which observed result BEST confirms that the security requirement is met?

  1. Users with acceptable identities and devices reach protected apps while stolen passwords or untrusted device states fail authorization.
  2. A device that fails posture moves to remediation or disconnects under the updated policy without requiring a full network restart.
  3. An enrolled printer communicates only with approved print services while an unknown MAC does not gain employee privileges.
  4. A controlled policy change reaches the correct active session and either reauthenticates or terminates it as intended.

Explanation

Correct Answer

B:

A device that fails posture moves to remediation or disconnects under the updated policy without requiring a full network restart. This is an observable acceptance condition, rather than an assumption that enabling a feature alone proves security. CoA allows an AAA policy server to request changes to an existing access session; it requires compatible network device settings and correct session matching. Situation: A help desk restores endpoint compliance and wants Cisco ISE to reauthorize the current session automatically.

Incorrect Answers

A:

Users with acceptable identities and devices reach protected apps while stolen passwords or untrusted device states fail authorization. This outcome tests Cisco Duo multifactor and device trust policy and is not sufficient proof of the stated requirement. Here the relevant validation is: A device that fails posture moves to remediation or disconnects under the updated policy without requiring a full network restart. Situation: A help desk restores endpoint compliance and wants Cisco ISE to reauthorize the current session automatically.

C:

An enrolled printer communicates only with approved print services while an unknown MAC does not gain employee privileges. This outcome tests MAB fallback and printer restriction and is not sufficient proof of the stated requirement. Here the relevant validation is: A device that fails posture moves to remediation or disconnects under the updated policy without requiring a full network restart. Situation: A help desk restores endpoint compliance and wants Cisco ISE to reauthorize the current session automatically.

D:

A controlled policy change reaches the correct active session and either reauthenticates or terminates it as intended. This outcome tests CoA failure and authorization policy debugging and is not sufficient proof of the stated requirement. Here the relevant validation is: A device that fails posture moves to remediation or disconnects under the updated policy without requiring a full network restart. Situation: A help desk restores endpoint compliance and wants Cisco ISE to reauthorize the current session automatically.

Question 580

A switch discards CoA messages after its dynamic-author client shared secret is rotated incorrectly. Which Cisco security control or operational response BEST addresses the stated need?

  1. Correlate Cisco XDR observables, endpoint detections, email, and network events to establish incident scope and response before automating containment.
  2. Use Cisco Duo SSO and Adaptive Access to apply policy based on user group, application sensitivity, location or risk, and device health where supported.
  3. Use RADIUS Change of Authorization to trigger reauthentication or update access on an active network session when identity or posture changes.
  4. Trace failed Cisco ISE CoA requests through dynamic authorization configuration, source identity, shared secret, session selection, and device support.

Explanation

Correct Answer

D:

Trace failed Cisco ISE CoA requests through dynamic authorization configuration, source identity, shared secret, session selection, and device support. This control addresses the failure mechanism and narrows the enforcement boundary. A policy rule update does not retroactively rewrite an existing session without a supported reauthorization mechanism and a successful CoA exchange. Confirm pre-change conditions using: Inspect CoA NAK or timeout records, UDP transport, session identifiers, network device shared secret, and switch logs. Situation: A switch discards CoA messages after its dynamic-author client shared secret is rotated incorrectly.

Incorrect Answers

A:

Correlate Cisco XDR observables, endpoint detections, email, and network events to establish incident scope and response before automating containment. This response applies to Cisco XDR cross-source incident correlation, not the controlling requirement in this case. XDR brings signals across integrated controls; cross-product visibility depends on healthy connectors and source coverage. For this scenario, the targeted action is: Trace failed Cisco ISE CoA requests through dynamic authorization configuration, source identity, shared secret, session selection, and device support. Situation: A switch discards CoA messages after its dynamic-author client shared secret is rotated incorrectly.

B:

Use Cisco Duo SSO and Adaptive Access to apply policy based on user group, application sensitivity, location or risk, and device health where supported. This response applies to Duo Adaptive Access and SSO context, not the controlling requirement in this case. Single sign-on simplifies authentication flow but does not mean every connected application should share identical authorization and risk policy. For this scenario, the targeted action is: Trace failed Cisco ISE CoA requests through dynamic authorization configuration, source identity, shared secret, session selection, and device support. Situation: A switch discards CoA messages after its dynamic-author client shared secret is rotated incorrectly.

C:

Use RADIUS Change of Authorization to trigger reauthentication or update access on an active network session when identity or posture changes. This response applies to CoA session reauthorization by Cisco ISE, not the controlling requirement in this case. CoA allows an AAA policy server to request changes to an existing access session; it requires compatible network device settings and correct session matching. For this scenario, the targeted action is: Trace failed Cisco ISE CoA requests through dynamic authorization configuration, source identity, shared secret, session selection, and device support. Situation: A switch discards CoA messages after its dynamic-author client shared secret is rotated incorrectly.
