Question 710

An administrator receives a push notification she did not initiate after a supplier email requests account verification. Which observed result BEST confirms that the security requirement is met?

  1. Repeated authorized execution preserves the intended single rule and failed updates can be reverted without unintended duplicate objects.
  2. A stolen integration token cannot read unrelated records and anomalous access triggers containment and credential replacement.
  3. A forged login page cannot grant privileged access using only a stolen password and abnormal sign-ins generate reviewable alerts.
  4. One failed perimeter control does not provide unmonitored unrestricted access to sensitive workloads.

Explanation

Correct Answer

C:

A forged login page cannot grant privileged access using only a stolen password and abnormal sign-ins generate reviewable alerts. This is an observable acceptance condition, rather than an assumption that enabling a feature alone proves security. Phishing harvests authentication material; contextual verification and phishing-resistant authenticators reduce credential replay risk without proving all messages are safe. Situation: An administrator receives a push notification she did not initiate after a supplier email requests account verification.

Incorrect Answers

A:

Repeated authorized execution preserves the intended single rule and failed updates can be reverted without unintended duplicate objects. This outcome tests Idempotent policy automation and rollback and is not sufficient proof of the stated requirement. Here the relevant validation is: A forged login page cannot grant privileged access using only a stolen password and abnormal sign-ins generate reviewable alerts. Situation: An administrator receives a push notification she did not initiate after a supplier email requests account verification.

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: A forged login page cannot grant privileged access using only a stolen password and abnormal sign-ins generate reviewable alerts. Situation: An administrator receives a push notification she did not initiate after a supplier email requests account verification.

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: A forged login page cannot grant privileged access using only a stolen password and abnormal sign-ins generate reviewable alerts. Situation: An administrator receives a push notification she did not initiate after a supplier email requests account verification.

Question 711

A bank requires stricter verification for administrator actions than for opening a non-sensitive team calendar. Which Cisco security control or operational response BEST addresses the stated need?

  1. Use Cisco Duo SSO and Adaptive Access to apply policy based on user group, application sensitivity, location or risk, and device health where supported.
  2. Enforce appropriate Cisco Duo MFA and device trust checks for protected applications, considering user role and device security status.
  3. Identify suspicious DNS-based data movement using query entropy, length, volume, domain ownership, and endpoint context before containment.
  4. Separate employee, guest, and personally owned device onboarding through Cisco ISE identity and authorization policies matched to legitimate use.

Explanation

Correct Answer

A:

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 bank requires stricter verification for administrator actions than for opening a non-sensitive team calendar.

Incorrect Answers

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 bank requires stricter verification for administrator actions than for opening a non-sensitive team calendar.

C:

Identify suspicious DNS-based data movement using query entropy, length, volume, domain ownership, and endpoint context before containment. This response applies to DNS tunneling exfiltration detection, not the controlling requirement in this case. DNS is a name-resolution protocol but can carry encoded data in labels or answers; unusual queries require contextual analysis to avoid false positives. 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 bank requires stricter verification for administrator actions than for opening a non-sensitive team calendar.

D:

Separate employee, guest, and personally owned device onboarding through Cisco ISE identity and authorization policies matched to legitimate use. This response applies to Cisco ISE guest and BYOD identity policies, not the controlling requirement in this case. Guest access and BYOD onboarding are authorization workflows, not a grant of permanent trusted access merely because a device connects to Wi-Fi. 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 bank requires stricter verification for administrator actions than for opening a non-sensitive team calendar.

Question 712

A previously quarantined malware file appears in an old weekly report but no new execution or connection is observed. Before changing security policy, what evidence should the engineer examine FIRST?

  1. Inspect disposition change, prevalence, isolation status, affected host roles, event sequence, and unresolved detections.
  2. Inspect exclusion path or hash, triggering detection, business impact, owner approval, and endpoint policy revision.
  3. Inspect file trajectory, device trajectory, hash reputation, user identity, process parentage, and action taken.
  4. Inspect prevention rules, process telemetry, behavioral detection coverage, isolation actions, and response history.

Explanation

Correct Answer

A:

Inspect disposition change, prevalence, isolation status, affected host roles, event sequence, and unresolved detections. This checks the relevant condition before an engineer modifies production access or detection behavior. Alert counts alone do not establish incident severity; containment status and evidence of active execution change urgency. The controlled response would be: Prioritize Secure Endpoint alerts by severity, current host risk, file action, correlated detections, and business criticality. Situation: A previously quarantined malware file appears in an old weekly report but no new execution or connection is observed.

Incorrect Answers

B:

Inspect exclusion path or hash, triggering detection, business impact, owner approval, and endpoint policy revision. This evidence addresses Secure Endpoint response exclusions and policy safety; it would not establish the primary issue here. The diagnostic evidence needed for this scenario is: Inspect disposition change, prevalence, isolation status, affected host roles, event sequence, and unresolved detections. Situation: A previously quarantined malware file appears in an old weekly report but no new execution or connection is observed.

C:

Inspect file trajectory, device trajectory, hash reputation, user identity, process parentage, and action taken. This evidence addresses Secure Endpoint detection event trajectory; it would not establish the primary issue here. The diagnostic evidence needed for this scenario is: Inspect disposition change, prevalence, isolation status, affected host roles, event sequence, and unresolved detections. Situation: A previously quarantined malware file appears in an old weekly report but no new execution or connection is observed.

D:

Inspect prevention rules, process telemetry, behavioral detection coverage, isolation actions, and response history. This evidence addresses Endpoint protection versus detection response; it would not establish the primary issue here. The diagnostic evidence needed for this scenario is: Inspect disposition change, prevalence, isolation status, affected host roles, event sequence, and unresolved detections. Situation: A previously quarantined malware file appears in an old weekly report but no new execution or connection is observed.

Question 713

A compromised web server scans database servers on the same flat subnet without traversing perimeter controls. Which Cisco security control or operational response BEST addresses the stated need?

  1. Deploy stateful inspection at defined trust boundaries and enable intrusion inspection on traffic paths where attack detection and blocking are required.
  2. Apply access-port security, storm thresholds, and BPDU safeguards according to host role to limit CAM abuse and accidental switching loops.
  3. Place appropriate firewall or distributed policy enforcement around both internet-facing flows and lateral workload communications.
  4. Use SNMPv3 with authentication and privacy where appropriate and restrict agents to approved management sources and read views.

Explanation

Correct Answer

C:

Place appropriate firewall or distributed policy enforcement around both internet-facing flows and lateral workload communications. This control addresses the failure mechanism and narrows the enforcement boundary. Perimeter inspection focuses north-south traffic; internal segmentation contains east-west lateral movement when workloads share a network. Confirm pre-change conditions using: Inspect ingress and internal traffic paths, application dependencies, firewall capabilities, and current east-west allow rules. Situation: A compromised web server scans database servers on the same flat subnet without traversing perimeter controls.

Incorrect Answers

A:

Deploy stateful inspection at defined trust boundaries and enable intrusion inspection on traffic paths where attack detection and blocking are required. This response applies to Stateful firewall and IPS placement, not the controlling requirement in this case. A stateful firewall tracks sessions and permitted flows; an IPS examines suspicious content and requires traffic visibility and appropriate inline enforcement. For this scenario, the targeted action is: Place appropriate firewall or distributed policy enforcement around both internet-facing flows and lateral workload communications. Situation: A compromised web server scans database servers on the same flat subnet without traversing perimeter controls.

B:

Apply access-port security, storm thresholds, and BPDU safeguards according to host role to limit CAM abuse and accidental switching loops. This response applies to Layer 2 port hardening and storm control, not the controlling requirement in this case. Port security limits learned MAC identities and BPDU guard helps protect intended edge ports; storm control limits damaging broadcast or multicast spikes. For this scenario, the targeted action is: Place appropriate firewall or distributed policy enforcement around both internet-facing flows and lateral workload communications. Situation: A compromised web server scans database servers on the same flat subnet without traversing perimeter controls.

D:

Use SNMPv3 with authentication and privacy where appropriate and restrict agents to approved management sources and read views. This response applies to SNMPv3 authenticated encrypted polling, not the controlling requirement in this case. SNMPv3 supports integrity and encryption for management queries when authPriv is configured; SNMPv1 community strings do not provide equivalent protection. For this scenario, the targeted action is: Place appropriate firewall or distributed policy enforcement around both internet-facing flows and lateral workload communications. Situation: A compromised web server scans database servers on the same flat subnet without traversing perimeter controls.

Question 714

A workstation announces itself as the default router and redirects neighboring users through its network card. Which Cisco security control or operational response BEST addresses the stated need?

  1. Protect programmable device management with authenticated endpoints, transport encryption, role authorization, and change transaction logging.
  2. Use Dynamic ARP Inspection with reliable IP-to-MAC bindings to reject forged ARP claims on untrusted access interfaces.
  3. Trace FTD VPN encryption/decryption counters, routes, NAT exemptions, and ACL matching when IKE is up but applications fail.
  4. Apply access-port security, storm thresholds, and BPDU safeguards according to host role to limit CAM abuse and accidental switching loops.

Explanation

Correct Answer

B:

Use Dynamic ARP Inspection with reliable IP-to-MAC bindings to reject forged ARP claims on untrusted access interfaces. This control addresses the failure mechanism and narrows the enforcement boundary. DAI relies on trustworthy binding information; enabling inspection without handling static addressing can interrupt legitimate users. Confirm pre-change conditions using: Inspect DHCP snooping bindings or static ARP ACLs, trusted links, validation drops, and legitimate static IP exceptions. Situation: A workstation announces itself as the default router and redirects neighboring users through its network card.

Incorrect Answers

A:

Protect programmable device management with authenticated endpoints, transport encryption, role authorization, and change transaction logging. This response applies to NETCONF RESTCONF and API management security, not the controlling requirement in this case. Programmable interfaces are management planes with security obligations comparable to CLI access; enabling RESTCONF does not itself validate an automation request. For this scenario, the targeted action is: Use Dynamic ARP Inspection with reliable IP-to-MAC bindings to reject forged ARP claims on untrusted access interfaces. Situation: A workstation announces itself as the default router and redirects neighboring users through its network card.

C:

Trace FTD VPN encryption/decryption counters, routes, NAT exemptions, and ACL matching when IKE is up but applications fail. This response applies to FTD VPN up but no protected data, not the controlling requirement in this case. IKE-up status validates part of the control plane; the protected data plane requires matching routes, selectors, and NAT behavior. For this scenario, the targeted action is: Use Dynamic ARP Inspection with reliable IP-to-MAC bindings to reject forged ARP claims on untrusted access interfaces. Situation: A workstation announces itself as the default router and redirects neighboring users through its network card.

D:

Apply access-port security, storm thresholds, and BPDU safeguards according to host role to limit CAM abuse and accidental switching loops. This response applies to Layer 2 port hardening and storm control, not the controlling requirement in this case. Port security limits learned MAC identities and BPDU guard helps protect intended edge ports; storm control limits damaging broadcast or multicast spikes. For this scenario, the targeted action is: Use Dynamic ARP Inspection with reliable IP-to-MAC bindings to reject forged ARP claims on untrusted access interfaces. Situation: A workstation announces itself as the default router and redirects neighboring users through its network card.

Question 715

An access port unexpectedly receives spanning-tree BPDUs from a new device connected under a desk. Before changing security policy, what evidence should the engineer examine FIRST?

  1. Inspect learned MAC counts, access versus trunk state, BPDU reception, storm-control counters, and port error events.
  2. Inspect VLAN enablement, trusted port design, binding table entries, DHCP offer sources, and port limits.
  3. Inspect Access-Request/Accept/Reject behavior, NAS identity, network path, policy rule match, certificates for EAP, and session logs.
  4. Review syslog destinations, transport security, facility and severity filters, log loss, NTP synchronization, and collector permissions.

Explanation

Correct Answer

A:

Inspect learned MAC counts, access versus trunk state, BPDU reception, storm-control counters, and port error events. This checks the relevant condition before an engineer modifies production access or detection behavior. Port security limits learned MAC identities and BPDU guard helps protect intended edge ports; storm control limits damaging broadcast or multicast spikes. The controlled response would be: Apply access-port security, storm thresholds, and BPDU safeguards according to host role to limit CAM abuse and accidental switching loops. Situation: An access port unexpectedly receives spanning-tree BPDUs from a new device connected under a desk.

Incorrect Answers

B:

Inspect VLAN enablement, trusted port design, binding table entries, DHCP offer sources, and port limits. This evidence addresses DHCP snooping trust and rogue server control; it would not establish the primary issue here. The diagnostic evidence needed for this scenario is: Inspect learned MAC counts, access versus trunk state, BPDU reception, storm-control counters, and port error events. Situation: An access port unexpectedly receives spanning-tree BPDUs from a new device connected under a desk.

C:

Inspect Access-Request/Accept/Reject behavior, NAS identity, network path, policy rule match, certificates for EAP, and session logs. This evidence addresses RADIUS network access troubleshooting; it would not establish the primary issue here. The diagnostic evidence needed for this scenario is: Inspect learned MAC counts, access versus trunk state, BPDU reception, storm-control counters, and port error events. Situation: An access port unexpectedly receives spanning-tree BPDUs from a new device connected under a desk.

D:

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 learned MAC counts, access versus trunk state, BPDU reception, storm-control counters, and port error events. Situation: An access port unexpectedly receives spanning-tree BPDUs from a new device connected under a desk.

Question 716

Several staff receive a fake device-enrollment portal link hosted on a recently created domain. Which TWO complementary steps provide the most defensible remediation and its supporting assessment? Select TWO.

  1. Combine suspicious message reporting, web destination inspection, reputation controls, and user training with enforceable authentication policies.
  2. Injected script is displayed inertly and forged cross-site requests cannot perform authorized state changes without valid defenses.
  3. Verify payment or access-change requests through an independently established channel and enforce dual approval for high-impact changes.
  4. Inspect site prefix growth, routing requirements, traffic selectors, tunnel-interface support, and failover paths.
  5. Inspect phishing URL redirects, domain registration context, email authentication outcomes, clicked-user telemetry, and current block rules.

Explanation

Correct Answers

A:

Combine suspicious message reporting, web destination inspection, reputation controls, and user training with enforceable authentication policies. This control addresses the failure mechanism and narrows the enforcement boundary. A secure email channel and DNS/web controls reduce exposure but cannot certify that every newly registered domain is benign. Confirm pre-change conditions using: Inspect phishing URL redirects, domain registration context, email authentication outcomes, clicked-user telemetry, and current block rules. This is the implementation portion of the complementary pair. Situation: Several staff receive a fake device-enrollment portal link hosted on a recently created domain.

E:

Inspect phishing URL redirects, domain registration context, email authentication outcomes, clicked-user telemetry, and current block rules. This checks the relevant condition before an engineer modifies production access or detection behavior. A secure email channel and DNS/web controls reduce exposure but cannot certify that every newly registered domain is benign. The controlled response would be: Combine suspicious message reporting, web destination inspection, reputation controls, and user training with enforceable authentication policies. This supplies the diagnostic evidence needed for the complementary action. Situation: Several staff receive a fake device-enrollment portal link hosted on a recently created domain.

Incorrect Answers

B:

Injected script is displayed inertly and forged cross-site requests cannot perform authorized state changes without valid defenses. 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: Combine suspicious message reporting, web destination inspection, reputation controls, and user training with enforceable authentication policies. and Inspect phishing URL redirects, domain registration context, email authentication outcomes, clicked-user telemetry, and current block rules. Situation: Several staff receive a fake device-enrollment portal link hosted on a recently created domain.

C:

Verify payment or access-change requests through an independently established channel and enforce dual approval for high-impact changes. This step could matter for Business email compromise verification but is not part of the required complementary pair for this case. The paired steps are: Combine suspicious message reporting, web destination inspection, reputation controls, and user training with enforceable authentication policies. and Inspect phishing URL redirects, domain registration context, email authentication outcomes, clicked-user telemetry, and current block rules. Situation: Several staff receive a fake device-enrollment portal link hosted on a recently created domain.

D:

Inspect site prefix growth, routing requirements, traffic selectors, tunnel-interface support, and failover paths. 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: Combine suspicious message reporting, web destination inspection, reputation controls, and user training with enforceable authentication policies. and Inspect phishing URL redirects, domain registration context, email authentication outcomes, clicked-user telemetry, and current block rules. Situation: Several staff receive a fake device-enrollment portal link hosted on a recently created domain.

Question 717

A development workstation is added to Secure Endpoint but inherits a monitor-only test policy instead of production protection. Before changing security policy, what evidence should the engineer examine FIRST?

  1. Inspect original file hash, current cloud disposition, execution history, file trajectory, and response capability.
  2. Inspect MDM enrollment status, device serial identifiers, operating system version, policy compliance, and assigned owner.
  3. Inspect installed modules, version compatibility, connector status, management profile, and identity mapping.
  4. Inspect endpoint groups, policy assignment, connector state, disposition settings, exclusions, and event history.

Explanation

Correct Answer

D:

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 development workstation is added to Secure Endpoint but inherits a monitor-only test policy instead of production protection.

Incorrect Answers

A:

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 development workstation is added to Secure Endpoint but inherits a monitor-only test policy instead of production protection.

B:

Inspect MDM enrollment status, device serial identifiers, operating system version, policy compliance, and assigned owner.

Question 718

A pipeline deploys a public image by mutable latest tag with no digest pinning or vulnerability assessment. Which TWO complementary steps provide the most defensible remediation and its supporting assessment? Select TWO.

  1. Inspect dependency scan outputs, container registry status, build provenance, release gates, and remediation ownership.
  2. Inspect image signatures or digests, container service accounts, secrets mounts, node permissions, and east-west traffic.
  3. Use appropriately supported eBPF-based observation to understand process and network activity without assuming kernel hooks enforce every application policy.
  4. Users reach authorized cloud services while prohibited sharing patterns and unsanctioned SaaS activity are identified.
  5. Protect container workloads with approved image provenance, minimal privileges, network boundaries, and runtime monitoring.

Explanation

Correct Answers

B:

Inspect image signatures or digests, container service accounts, secrets mounts, node permissions, and east-west traffic. This checks the relevant condition before an engineer modifies production access or detection behavior. A container isolates processes but is not a complete trust boundary; host privileges, image supply chain, and runtime identity remain material. The controlled response would be: Protect container workloads with approved image provenance, minimal privileges, network boundaries, and runtime monitoring. This supplies the diagnostic evidence needed for the complementary action. Situation: A pipeline deploys a public image by mutable latest tag with no digest pinning or vulnerability assessment.

E:

Protect container workloads with approved image provenance, minimal privileges, network boundaries, and runtime monitoring. This control addresses the failure mechanism and narrows the enforcement boundary. A container isolates processes but is not a complete trust boundary; host privileges, image supply chain, and runtime identity remain material. Confirm pre-change conditions using: Inspect image signatures or digests, container service accounts, secrets mounts, node permissions, and east-west traffic. This is the implementation portion of the complementary pair. Situation: A pipeline deploys a public image by mutable latest tag with no digest pinning or vulnerability assessment.

Incorrect Answers

A:

Inspect dependency scan outputs, container registry status, build provenance, release gates, and remediation ownership. 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: Protect container workloads with approved image provenance, minimal privileges, network boundaries, and runtime monitoring. and Inspect image signatures or digests, container service accounts, secrets mounts, node permissions, and east-west traffic. Situation: A pipeline deploys a public image by mutable latest tag with no digest pinning or vulnerability assessment.

C:

Use appropriately supported eBPF-based observation to understand process and network activity without assuming kernel hooks enforce every application policy. 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: Protect container workloads with approved image provenance, minimal privileges, network boundaries, and runtime monitoring. and Inspect image signatures or digests, container service accounts, secrets mounts, node permissions, and east-west traffic. Situation: A pipeline deploys a public image by mutable latest tag with no digest pinning or vulnerability assessment.

D:

Question 719

An ISE dashboard shows CoA requests with no effect because the switch rejects dynamic authorization packets. Which Cisco security control or operational response BEST addresses the stated need?

  1. Separate employee, guest, and personally owned device onboarding through Cisco ISE identity and authorization policies matched to legitimate use.
  2. Trace failed Cisco ISE CoA requests through dynamic authorization configuration, source identity, shared secret, session selection, and device support.
  3. Use RADIUS Change of Authorization to trigger reauthentication or update access on an active network session when identity or posture changes.
  4. Enforce network access requirements for device OS, required security controls, and application compliance, with remediation for failures.

Explanation

Correct Answer

C:

Use RADIUS Change of Authorization to trigger reauthentication or update access on an active network session when identity or posture changes. This control addresses the failure mechanism and narrows the enforcement boundary. CoA allows an AAA policy server to request changes to an existing access session; it requires compatible network device settings and correct session matching. Confirm pre-change conditions using: Inspect current session identity, NAD CoA support and shared secret, ISE authorization change, and RADIUS live logs. Situation: An ISE dashboard shows CoA requests with no effect because the switch rejects dynamic authorization packets.

Incorrect Answers

A:

Separate employee, guest, and personally owned device onboarding through Cisco ISE identity and authorization policies matched to legitimate use. This response applies to Cisco ISE guest and BYOD identity policies, not the controlling requirement in this case. Guest access and BYOD onboarding are authorization workflows, not a grant of permanent trusted access merely because a device connects to Wi-Fi. For this scenario, the targeted action is: Use RADIUS Change of Authorization to trigger reauthentication or update access on an active network session when identity or posture changes. Situation: An ISE dashboard shows CoA requests with no effect because the switch rejects dynamic authorization packets.

B:

Trace failed Cisco ISE CoA requests through dynamic authorization configuration, source identity, shared secret, session selection, and device support. This response applies to CoA failure and authorization policy debugging, not the controlling requirement in this case. A policy rule update does not retroactively rewrite an existing session without a supported reauthorization mechanism and a successful CoA exchange. For this scenario, the targeted action is: Use RADIUS Change of Authorization to trigger reauthentication or update access on an active network session when identity or posture changes. Situation: An ISE dashboard shows CoA requests with no effect because the switch rejects dynamic authorization packets.

D:

Enforce network access requirements for device OS, required security controls, and application compliance, with remediation for failures. This response applies to Endpoint application compliance and risk-based access, not the controlling requirement in this case. Device compliance is an ongoing assessment, not a once-per-device trust label; application control and identity must be combined for effective access. For this scenario, the targeted action is: Use RADIUS Change of Authorization to trigger reauthentication or update access on an active network session when identity or posture changes. Situation: An ISE dashboard shows CoA requests with no effect because the switch rejects dynamic authorization packets.

Question 720

After a firmware upgrade, one FTD peer offers only a different IKE encryption suite and IKE negotiation stops. Before changing security policy, what evidence should the engineer examine FIRST?

  1. Inspect VPN event traces, IKE negotiation state, certificate or PSK errors, UDP 500/4500, and proposal mismatches.
  2. Inspect bidirectional security association counters, packet traces, NAT policy, route selection, and remote selectors.
  3. Inspect SSH/HTTPS management services, NETCONF or RESTCONF configuration, model schema, access roles, and operation results.
  4. Inspect source/destination tuples, flow duration, byte counts, exporters, collector receipt, and sampling configuration.

Explanation

Correct Answer

A:

Inspect VPN event traces, IKE negotiation state, certificate or PSK errors, UDP 500/4500, and proposal mismatches. This checks the relevant condition before an engineer modifies production access or detection behavior. Tunnel establishment progresses through distinct authentication and negotiation stages; changing unrelated firewall rules cannot fix mismatched proposals. The controlled response would be: Diagnose VPN setup failures in phase order by comparing peer reachability, authentication identities, and mutually supported IKE and IPsec proposals. Situation: After a firmware upgrade, one FTD peer offers only a different IKE encryption suite and IKE negotiation stops.

Incorrect Answers

B:

Inspect bidirectional security association counters, packet traces, NAT policy, route selection, and remote selectors. This evidence addresses FTD VPN up but no protected data; it would not establish the primary issue here. The diagnostic evidence needed for this scenario is: Inspect VPN event traces, IKE negotiation state, certificate or PSK errors, UDP 500/4500, and proposal mismatches. Situation: After a firmware upgrade, one FTD peer offers only a different IKE encryption suite and IKE negotiation stops.

C:

Inspect SSH/HTTPS management services, NETCONF or RESTCONF configuration, model schema, access roles, and operation results. This evidence addresses NETCONF RESTCONF and API management security; it would not establish the primary issue here. The diagnostic evidence needed for this scenario is: Inspect VPN event traces, IKE negotiation state, certificate or PSK errors, UDP 500/4500, and proposal mismatches. Situation: After a firmware upgrade, one FTD peer offers only a different IKE encryption suite and IKE negotiation stops.

D:

Inspect source/destination tuples, flow duration, byte counts, exporters, collector receipt, and sampling configuration. This evidence addresses NetFlow and telemetry flow analysis; it would not establish the primary issue here. The diagnostic evidence needed for this scenario is: Inspect VPN event traces, IKE negotiation state, certificate or PSK errors, UDP 500/4500, and proposal mismatches. Situation: After a firmware upgrade, one FTD peer offers only a different IKE encryption suite and IKE negotiation stops.
