Question 270

A project wants to deploy application updates automatically but must retain evidence of developer and security approval. Which observed result BEST confirms that the security requirement is met?

  1. Misconfigured public resources are detected and controlled while approved exceptions remain documented and reviewed.
  2. A deliberately public data service or embedded secret is rejected in CI before a production resource is created.
  3. A critical vulnerable dependency blocks promotion and approved remediation produces an auditable releasable artifact.
  4. Required cloud audit events are searchable with accurate timestamps and identifiable source fields after ingestion.

Explanation

Correct Answer

C:

A critical vulnerable dependency blocks promotion and approved remediation produces an auditable releasable artifact. This is an observable acceptance condition, rather than an assumption that enabling a feature alone proves security. DevSecOps embeds security early in delivery while preserving trusted runtime controls; scanning after production is not an adequate release gate. Situation: A project wants to deploy application updates automatically but must retain evidence of developer and security approval.

Incorrect Answers

A:

Misconfigured public resources are detected and controlled while approved exceptions remain documented and reviewed. This outcome tests Cloud security posture policy selection and is not sufficient proof of the stated requirement. Here the relevant validation is: A critical vulnerable dependency blocks promotion and approved remediation produces an auditable releasable artifact. Situation: A project wants to deploy application updates automatically but must retain evidence of developer and security approval.

B:

A deliberately public data service or embedded secret is rejected in CI before a production resource is created. This outcome tests Infrastructure as Code security gate and is not sufficient proof of the stated requirement. Here the relevant validation is: A critical vulnerable dependency blocks promotion and approved remediation produces an auditable releasable artifact. Situation: A project wants to deploy application updates automatically but must retain evidence of developer and security approval.

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: A critical vulnerable dependency blocks promotion and approved remediation produces an auditable releasable artifact. Situation: A project wants to deploy application updates automatically but must retain evidence of developer and security approval.

Question 271

Remote staff can sign in to Secure Access but the private finance app fails after its internal address changes. Which observed result BEST confirms that the security requirement is met?

  1. A failover test maintains authorized access and a broken backend is diagnosed without broadly opening the private network.
  2. An approved web app remains reachable while a test prohibited destination produces an attributable deny event.
  3. A contractor reaches one approved HR web app without gaining routed reachability to unrelated production subnets.
  4. A suspicious destination is associated with affected users and a tested response without sweeping unrelated shared cloud infrastructure.

Explanation

Correct Answer

A:

A failover test maintains authorized access and a broken backend is diagnosed without broadly opening the private network. This is an observable acceptance condition, rather than an assumption that enabling a feature alone proves security. A successful user login proves authentication, not connector reachability or correct backend application mapping. Situation: Remote staff can sign in to Secure Access but the private finance app fails after its internal address changes.

Incorrect Answers

B:

An approved web app remains reachable while a test prohibited destination produces an attributable deny event. This outcome tests Cisco Secure Access internet use policy and is not sufficient proof of the stated requirement. Here the relevant validation is: A failover test maintains authorized access and a broken backend is diagnosed without broadly opening the private network. Situation: Remote staff can sign in to Secure Access but the private finance app fails after its internal address changes.

C:

A contractor reaches one approved HR web app without gaining routed reachability to unrelated production subnets. This outcome tests Cisco Secure Access private app access and is not sufficient proof of the stated requirement. Here the relevant validation is: A failover test maintains authorized access and a broken backend is diagnosed without broadly opening the private network. Situation: Remote staff can sign in to Secure Access but the private finance app fails after its internal address changes.

D:

A suspicious destination is associated with affected users and a tested response without sweeping unrelated shared cloud infrastructure. This outcome tests Investigate infrastructure attribution and false positives and is not sufficient proof of the stated requirement. Here the relevant validation is: A failover test maintains authorized access and a broken backend is diagnosed without broadly opening the private network. Situation: Remote staff can sign in to Secure Access but the private finance app fails after its internal address changes.

Question 272

An edge device suffers CPU spikes from unwanted control-plane traffic while transit forwarding remains otherwise normal. Which Cisco security control or operational response BEST addresses the stated need?

  1. Correlate encrypted flow characteristics with endpoint, DNS, and identity context rather than assuming encrypted payloads are visible to ordinary sensors.
  2. Apply access-port security, storm thresholds, and BPDU safeguards according to host role to limit CAM abuse and accidental switching loops.
  3. Limit administrative exposure, authenticate routing and management where supported, and protect control-plane resources against abuse.
  4. Compare running Cisco IOS XE or Secure Firewall settings to an applicable CIS benchmark, document justified exceptions, and remediate deviations.

Explanation

Correct Answer

C:

Limit administrative exposure, authenticate routing and management where supported, and protect control-plane resources against abuse. This control addresses the failure mechanism and narrows the enforcement boundary. A network device has distinct control, data, and management planes; each requires separate scoped protection. Confirm pre-change conditions using: Review VTY/SSH configuration, management VRFs or ACLs, CoPP policy, routing adjacencies, and logging paths. Situation: An edge device suffers CPU spikes from unwanted control-plane traffic while transit forwarding remains otherwise normal.

Incorrect Answers

A:

Correlate encrypted flow characteristics with endpoint, DNS, and identity context rather than assuming encrypted payloads are visible to ordinary sensors. This response applies to Encrypted network telemetry and correlated detection, not the controlling requirement in this case. Encrypted traffic analytics can leverage metadata and behavior; encryption reduces payload visibility and does not make a flow automatically benign. For this scenario, the targeted action is: Limit administrative exposure, authenticate routing and management where supported, and protect control-plane resources against abuse. Situation: An edge device suffers CPU spikes from unwanted control-plane traffic while transit forwarding remains otherwise normal.

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: Limit administrative exposure, authenticate routing and management where supported, and protect control-plane resources against abuse. Situation: An edge device suffers CPU spikes from unwanted control-plane traffic while transit forwarding remains otherwise normal.

D:

Compare running Cisco IOS XE or Secure Firewall settings to an applicable CIS benchmark, document justified exceptions, and remediate deviations. This response applies to CIS device configuration baseline assessment, not the controlling requirement in this case. Security benchmarks are version-specific prescriptive baselines; blindly applying all recommendations without operational review can disrupt required services. For this scenario, the targeted action is: Limit administrative exposure, authenticate routing and management where supported, and protect control-plane resources against abuse. Situation: An edge device suffers CPU spikes from unwanted control-plane traffic while transit forwarding remains otherwise normal.

Question 273

A public booking API receives millions of near-identical requests while the web nodes show no suspicious new executables. Which Cisco security control or operational response BEST addresses the stated need?

  1. Constrain compromised API credentials through scoped permissions, rotation, behavior alerts, and incident review rather than assuming encrypted transport prevents misuse.
  2. Differentiate traffic-exhaustion attacks from host malware by inspecting network utilization, service saturation, and endpoint behavior before choosing containment.
  3. Choose route-based IPsec tunnels when dynamic routed topologies need predictable overlay interfaces and matched security policies.
  4. Treat retrieved pages, documents, and tool responses as untrusted data and enforce tool authorization outside model-generated instructions.

Explanation

Correct Answer

B:

Differentiate traffic-exhaustion attacks from host malware by inspecting network utilization, service saturation, and endpoint behavior before choosing containment. This control addresses the failure mechanism and narrows the enforcement boundary. A volumetric DDoS overwhelms service capacity whereas a Trojan executes on a host; discriminating evidence is required for targeted controls. Confirm pre-change conditions using: Examine flow spikes, source distributions, server resource graphs, load-balancer logs, and endpoint execution telemetry. Situation: A public booking API receives millions of near-identical requests while the web nodes show no suspicious new executables.

Incorrect Answers

A:

Constrain compromised API credentials through scoped permissions, rotation, behavior alerts, and incident review rather than assuming encrypted transport prevents misuse. This response applies to Cloud API breach and lateral movement, not the controlling requirement in this case. Encryption in transit protects a channel but does not limit an authorized-looking API request carrying a stolen bearer token. For this scenario, the targeted action is: Differentiate traffic-exhaustion attacks from host malware by inspecting network utilization, service saturation, and endpoint behavior before choosing containment. Situation: A public booking API receives millions of near-identical requests while the web nodes show no suspicious new executables.

C:

Choose route-based IPsec tunnels when dynamic routed topologies need predictable overlay interfaces and matched security policies. This response applies to Route-based versus policy-based VPN design, not the controlling requirement in this case. Route-based VPN separates routing decisions from the cryptographic tunnel interface whereas policy-based VPN relies on matching crypto traffic definitions. For this scenario, the targeted action is: Differentiate traffic-exhaustion attacks from host malware by inspecting network utilization, service saturation, and endpoint behavior before choosing containment. Situation: A public booking API receives millions of near-identical requests while the web nodes show no suspicious new executables.

D:

Treat retrieved pages, documents, and tool responses as untrusted data and enforce tool authorization outside model-generated instructions. This response applies to Prompt injection trust boundary, not the controlling requirement in this case. Prompt injection occurs when lower-trust content is promoted to instruction authority; blocking unsafe tool effects requires enforcement beyond prompt wording. For this scenario, the targeted action is: Differentiate traffic-exhaustion attacks from host malware by inspecting network utilization, service saturation, and endpoint behavior before choosing containment. Situation: A public booking API receives millions of near-identical requests while the web nodes show no suspicious new executables.

Question 274

A SOC has duplicate firewall and endpoint alerts that create separate tickets instead of one prioritized incident. Which TWO complementary steps provide the most defensible remediation and its supporting assessment? Select TWO.

  1. Use Splunk detection, field normalization, incident enrichment, and approved SOAR actions to organize security-event handling at scale.
  2. A device that fails posture moves to remediation or disconnects under the updated policy without requiring a full network restart.
  3. Inspect detection search logic, sourcetype fields, incident assignment, playbook permissions, and result audit trail.
  4. Inspect issuing CA trust, certificate subject and EKU, expiry, device records, policy match, and failed EAP logs.
  5. Enforce appropriate Cisco Duo MFA and device trust checks for protected applications, considering user role and device security status.

Explanation

Correct Answers

A:

Use Splunk detection, field normalization, incident enrichment, and approved SOAR actions to organize security-event handling at scale. This control addresses the failure mechanism and narrows the enforcement boundary. Orchestration connects event evidence to repeatable response, but logs and playbook execution require separation of detection confidence and authorization. Confirm pre-change conditions using: Inspect detection search logic, sourcetype fields, incident assignment, playbook permissions, and result audit trail. This is the implementation portion of the complementary pair. Situation: A SOC has duplicate firewall and endpoint alerts that create separate tickets instead of one prioritized incident.

C:

Inspect detection search logic, sourcetype fields, incident assignment, playbook permissions, and result audit trail. This checks the relevant condition before an engineer modifies production access or detection behavior. Orchestration connects event evidence to repeatable response, but logs and playbook execution require separation of detection confidence and authorization. The controlled response would be: Use Splunk detection, field normalization, incident enrichment, and approved SOAR actions to organize security-event handling at scale. This supplies the diagnostic evidence needed for the complementary action. Situation: A SOC has duplicate firewall and endpoint alerts that create separate tickets instead of one prioritized incident.

Incorrect Answers

B:

A device that fails posture moves to remediation or disconnects under the updated policy without requiring a full network restart. This step could matter for CoA session reauthorization by Cisco ISE but is not part of the required complementary pair for this case. The paired steps are: Use Splunk detection, field normalization, incident enrichment, and approved SOAR actions to organize security-event handling at scale. and Inspect detection search logic, sourcetype fields, incident assignment, playbook permissions, and result audit trail. Situation: A SOC has duplicate firewall and endpoint alerts that create separate tickets instead of one prioritized incident.

D:

Inspect issuing CA trust, certificate subject and EKU, expiry, device records, policy match, and failed EAP logs. This step could matter for Certificate identity and noncompliant access segregation but is not part of the required complementary pair for this case. The paired steps are: Use Splunk detection, field normalization, incident enrichment, and approved SOAR actions to organize security-event handling at scale. and Inspect detection search logic, sourcetype fields, incident assignment, playbook permissions, and result audit trail. Situation: A SOC has duplicate firewall and endpoint alerts that create separate tickets instead of one prioritized incident.

E:

Enforce appropriate Cisco Duo MFA and device trust checks for protected applications, considering user role and device security status. This step could matter for Cisco Duo multifactor and device trust policy but is not part of the required complementary pair for this case. The paired steps are: Use Splunk detection, field normalization, incident enrichment, and approved SOAR actions to organize security-event handling at scale. and Inspect detection search logic, sourcetype fields, incident assignment, playbook permissions, and result audit trail. Situation: A SOC has duplicate firewall and endpoint alerts that create separate tickets instead of one prioritized incident.

Question 275

An access port unexpectedly receives spanning-tree BPDUs from a new device connected under a desk. Which Cisco security control or operational response BEST addresses the stated need?

  1. Apply access-port security, storm thresholds, and BPDU safeguards according to host role to limit CAM abuse and accidental switching loops.
  2. Place appropriate firewall or distributed policy enforcement around both internet-facing flows and lateral workload communications.
  3. Assess Cisco Security Cloud Control against on-prem management requirements, identity controls, connectivity, and approved cloud operations.
  4. Enable DHCP snooping on the supported switch VLANs and trust only intended DHCP-server-facing interfaces.

Explanation

Correct Answer

A:

Apply access-port security, storm thresholds, and BPDU safeguards according to host role to limit CAM abuse and accidental switching loops. This control addresses the failure mechanism and narrows the enforcement boundary. Port security limits learned MAC identities and BPDU guard helps protect intended edge ports; storm control limits damaging broadcast or multicast spikes. Confirm pre-change conditions using: 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.

Incorrect Answers

B:

Place appropriate firewall or distributed policy enforcement around both internet-facing flows and lateral workload communications. This response applies to North south versus east west segmentation, not the controlling requirement in this case. Perimeter inspection focuses north-south traffic; internal segmentation contains east-west lateral movement when workloads share a network. For this scenario, the targeted action is: 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.

C:

Assess Cisco Security Cloud Control against on-prem management requirements, identity controls, connectivity, and approved cloud operations. This response applies to Cisco Security Cloud Control management boundary, not the controlling requirement in this case. Cloud-managed network policy still requires per-device compatibility, secure enrollment, change governance, and management connectivity. For this scenario, the targeted action is: 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.

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: 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.

Question 276

An organization allows one enterprise AI tenant but employee browsers can still open consumer AI services without policy. Which TWO complementary steps provide the most defensible remediation and its supporting assessment? Select TWO.

  1. Inspect private app connector reachability, application FQDN or IP definitions, identity group, posture, and access decisions.
  2. Create data loss prevention policies for defined sensitive patterns and approved destinations, with detection tuning and response actions.
  3. Apply AI service visibility and policy to protect sensitive inputs, approved destinations, and user identity when staff use external generative AI tools.
  4. High-risk destinations receive contextual response while low-risk but confirmed malicious domains are not automatically ignored.
  5. Inspect AI application usage records, policy category, sensitive text classification, prompt upload paths, and employee roles.

Explanation

Correct Answers

C:

Apply AI service visibility and policy to protect sensitive inputs, approved destinations, and user identity when staff use external generative AI tools. This control addresses the failure mechanism and narrows the enforcement boundary. A corporate AI policy requires enforceable data handling and approved services; blocking a few keywords does not alone control all exfiltration paths. Confirm pre-change conditions using: Inspect AI application usage records, policy category, sensitive text classification, prompt upload paths, and employee roles. This is the implementation portion of the complementary pair. Situation: An organization allows one enterprise AI tenant but employee browsers can still open consumer AI services without policy.

E:

Inspect AI application usage records, policy category, sensitive text classification, prompt upload paths, and employee roles. This checks the relevant condition before an engineer modifies production access or detection behavior. A corporate AI policy requires enforceable data handling and approved services; blocking a few keywords does not alone control all exfiltration paths. The controlled response would be: Apply AI service visibility and policy to protect sensitive inputs, approved destinations, and user identity when staff use external generative AI tools. This supplies the diagnostic evidence needed for the complementary action. Situation: An organization allows one enterprise AI tenant but employee browsers can still open consumer AI services without policy.

Incorrect Answers

A:

Inspect private app connector reachability, application FQDN or IP definitions, identity group, posture, and access decisions. This step could matter for Cisco Secure Access private app access but is not part of the required complementary pair for this case. The paired steps are: Apply AI service visibility and policy to protect sensitive inputs, approved destinations, and user identity when staff use external generative AI tools. and Inspect AI application usage records, policy category, sensitive text classification, prompt upload paths, and employee roles. Situation: An organization allows one enterprise AI tenant but employee browsers can still open consumer AI services without policy.

B:

Create data loss prevention policies for defined sensitive patterns and approved destinations, with detection tuning and response actions. This step could matter for Cloud DLP sensitive upload policy but is not part of the required complementary pair for this case. The paired steps are: Apply AI service visibility and policy to protect sensitive inputs, approved destinations, and user identity when staff use external generative AI tools. and Inspect AI application usage records, policy category, sensitive text classification, prompt upload paths, and employee roles. Situation: An organization allows one enterprise AI tenant but employee browsers can still open consumer AI services without policy.

D:

High-risk destinations receive contextual response while low-risk but confirmed malicious domains are not automatically ignored. This step could matter for Investigate domain risk score interpretation but is not part of the required complementary pair for this case. The paired steps are: Apply AI service visibility and policy to protect sensitive inputs, approved destinations, and user identity when staff use external generative AI tools. and Inspect AI application usage records, policy category, sensitive text classification, prompt upload paths, and employee roles. Situation: An organization allows one enterprise AI tenant but employee browsers can still open consumer AI services without policy.

Question 277

An Azure audit feed arrives in Splunk but all events have the ingestion timestamp instead of event time. Which observed result BEST confirms that the security requirement is met?

  1. Equivalent approved network and identity restrictions work on each target cloud without assuming policy formats are interchangeable.
  2. A test cloud privilege escalation is detected with linked sign-in and API activity rather than isolated low-context alerts.
  3. Users reach authorized cloud services while prohibited sharing patterns and unsanctioned SaaS activity are identified.
  4. Required cloud audit events are searchable with accurate timestamps and identifiable source fields after ingestion.

Explanation

Correct Answer

D:

Required cloud audit events are searchable with accurate timestamps and identifiable source fields after ingestion. This is an observable acceptance condition, rather than an assumption that enabling a feature alone proves security. Ingesting a log feed is not equivalent to normalizing it for investigations; sourcetype, event time, and parser correctness matter. Situation: An Azure audit feed arrives in Splunk but all events have the ingestion timestamp instead of event time.

Incorrect Answers

A:

Equivalent approved network and identity restrictions work on each target cloud without assuming policy formats are interchangeable. This outcome tests Multicloud identity and centralized policy governance and is not sufficient proof of the stated requirement. Here the relevant validation is: Required cloud audit events are searchable with accurate timestamps and identifiable source fields after ingestion. Situation: An Azure audit feed arrives in Splunk but all events have the ingestion timestamp instead of event time.

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: Required cloud audit events are searchable with accurate timestamps and identifiable source fields after ingestion. Situation: An Azure audit feed arrives in Splunk but all events have the ingestion timestamp instead of event time.

C:

Users reach authorized cloud services while prohibited sharing patterns and unsanctioned SaaS activity are identified. This outcome tests Cloud deployment and CASB suitability and is not sufficient proof of the stated requirement. Here the relevant validation is: Required cloud audit events are searchable with accurate timestamps and identifiable source fields after ingestion. Situation: An Azure audit feed arrives in Splunk but all events have the ingestion timestamp instead of event time.

Question 278

A cloud developer publishes a service token in a public repository and unexpected database exports appear overnight. Before changing security policy, what evidence should the engineer examine FIRST?

  1. Inspect sender and destination mismatch, sign-in geography, authentication strength, new device enrollment, and user-reported prompts.
  2. Review API audit calls, token audience and lifetime, privilege scope, abnormal exports, and linked cloud-resource access.
  3. Inspect embedding source sets, package provenance, vector index tenant filters, model artifacts, and integrity-check history.
  4. Review message authentication results, sender/domain similarities, original contact directory, transaction changes, and escalation records.

Explanation

Correct Answer

B:

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

Incorrect Answers

A:

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: Review API audit calls, token audience and lifetime, privilege scope, abnormal exports, and linked cloud-resource access. Situation: A cloud developer publishes a service token in a public repository and unexpected database exports appear overnight.

C:

Inspect embedding source sets, package provenance, vector index tenant filters, model artifacts, and integrity-check history. This evidence addresses Embedding and model supply chain risk; it would not establish the primary issue here. The diagnostic evidence needed for this scenario is: Review API audit calls, token audience and lifetime, privilege scope, abnormal exports, and linked cloud-resource access. Situation: A cloud developer publishes a service token in a public repository and unexpected database exports appear overnight.

D:

Review message authentication results, sender/domain similarities, original contact directory, transaction changes, and escalation records. This evidence addresses Business email compromise verification; it would not establish the primary issue here. The diagnostic evidence needed for this scenario is: Review API audit calls, token audience and lifetime, privilege scope, abnormal exports, and linked cloud-resource access. Situation: A cloud developer publishes a service token in a public repository and unexpected database exports appear overnight.

Question 279

An account has repeated denied Duo prompts from an unfamiliar location before a user reports attempted password theft. Which observed result BEST confirms that the security requirement is met?

  1. A riskier session receives a stronger verification or denial decision without blocking routine authorized access unnecessarily.
  2. Users with acceptable identities and devices reach protected apps while stolen passwords or untrusted device states fail authorization.
  3. A device that fails posture moves to remediation or disconnects under the updated policy without requiring a full network restart.
  4. An unauthorized sensitive export is detected and blocked or escalated while approved business uploads remain permitted.

Explanation

Correct Answer

B:

Users with acceptable identities and devices reach protected apps while stolen passwords or untrusted device states fail authorization. This is an observable acceptance condition, rather than an assumption that enabling a feature alone proves security. Multifactor authentication strengthens login assurance, while device trust and adaptive controls independently evaluate session risk. Situation: An account has repeated denied Duo prompts from an unfamiliar location before a user reports attempted password theft.

Incorrect Answers

A:

A riskier session receives a stronger verification or denial decision without blocking routine authorized access unnecessarily. This outcome tests Duo Adaptive Access and SSO context and is not sufficient proof of the stated requirement. Here the relevant validation is: Users with acceptable identities and devices reach protected apps while stolen passwords or untrusted device states fail authorization. Situation: An account has repeated denied Duo prompts from an unfamiliar location before a user reports attempted password theft.

C:

A device that fails posture moves to remediation or disconnects under the updated policy without requiring a full network restart. This outcome tests CoA session reauthorization by Cisco ISE and is not sufficient proof of the stated requirement. Here the relevant validation is: Users with acceptable identities and devices reach protected apps while stolen passwords or untrusted device states fail authorization. Situation: An account has repeated denied Duo prompts from an unfamiliar location before a user reports attempted password theft.

D:

An unauthorized sensitive export is detected and blocked or escalated while approved business uploads remain permitted. This outcome tests HTTPS and cloud-storage exfiltration containment and is not sufficient proof of the stated requirement. Here the relevant validation is: Users with acceptable identities and devices reach protected apps while stolen passwords or untrusted device states fail authorization. Situation: An account has repeated denied Duo prompts from an unfamiliar location before a user reports attempted password theft.

Question 280

A campus protects internet entry but leaves sensitive research servers open to every internal department. 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. Review fail-open or fail-closed expectations, high-availability topology, interface mode, IPS rule state, and packet counters.
  3. Inspect application detectors, URL category verdicts, rule conditions, encrypted-session visibility, and identity matches.
  4. Inspect ingress and internal traffic paths, application dependencies, firewall capabilities, and current east-west allow rules.

Explanation

Correct Answer

D:

Inspect ingress and internal traffic paths, application dependencies, firewall capabilities, and current east-west allow rules. This checks the relevant condition before an engineer modifies production access or detection behavior. Perimeter inspection focuses north-south traffic; internal segmentation contains east-west lateral movement when workloads share a network. The controlled response would be: Place appropriate firewall or distributed policy enforcement around both internet-facing flows and lateral workload communications. Situation: A campus protects internet entry but leaves sensitive research servers open to every internal department.

Incorrect Answers

A:

Inspect VPN event traces, IKE negotiation state, certificate or PSK errors, UDP 500/4500, and proposal mismatches. This evidence addresses FTD IKE negotiation failure isolation; it would not establish the primary issue here. The diagnostic evidence needed for this scenario is: Inspect ingress and internal traffic paths, application dependencies, firewall capabilities, and current east-west allow rules. Situation: A campus protects internet entry but leaves sensitive research servers open to every internal department.

B:

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 ingress and internal traffic paths, application dependencies, firewall capabilities, and current east-west allow rules. Situation: A campus protects internet entry but leaves sensitive research servers open to every internal department.

C:

Inspect application detectors, URL category verdicts, rule conditions, encrypted-session visibility, and identity matches. This evidence addresses Application visibility control and URL filtering; it would not establish the primary issue here. The diagnostic evidence needed for this scenario is: Inspect ingress and internal traffic paths, application dependencies, firewall capabilities, and current east-west allow rules.
