Question 1190

A campus protects internet entry but leaves sensitive research servers open to every internal department. Which observed result BEST confirms that the security requirement is met?

  1. Unauthorized connections are denied while known hostile payloads are detected by the intended inline intrusion policy without unrelated outages.
  2. Tested exploit traffic is detected or blocked by the configured policy while legitimate services remain available.
  3. Compromising one application tier does not grant unrestricted lateral access to adjacent protected workloads.
  4. Firewall and switch events share consistent time ordering and protected transport to the authorized log collector.

Explanation

Correct Answer

C:

Compromising one application tier does not grant unrestricted lateral access to adjacent protected workloads. This is an observable acceptance condition, rather than an assumption that enabling a feature alone proves security. Perimeter inspection focuses north-south traffic; internal segmentation contains east-west lateral movement when workloads share a network. Situation: A campus protects internet entry but leaves sensitive research servers open to every internal department.

Incorrect Answers

A:

Unauthorized connections are denied while known hostile payloads are detected by the intended inline intrusion policy without unrelated outages. This outcome tests Stateful firewall and IPS placement and is not sufficient proof of the stated requirement. Here the relevant validation is: Compromising one application tier does not grant unrestricted lateral access to adjacent protected workloads. Situation: A campus protects internet entry but leaves sensitive research servers open to every internal department.

B:

Tested exploit traffic is detected or blocked by the configured policy while legitimate services remain available. This outcome tests FTD intrusion policy and malware detection and is not sufficient proof of the stated requirement. Here the relevant validation is: Compromising one application tier does not grant unrestricted lateral access to adjacent protected workloads. Situation: A campus protects internet entry but leaves sensitive research servers open to every internal department.

D:

Firewall and switch events share consistent time ordering and protected transport to the authorized log collector. This outcome tests Secure syslog and timestamp correlation and is not sufficient proof of the stated requirement. Here the relevant validation is: Compromising one application tier does not grant unrestricted lateral access to adjacent protected workloads. Situation: A campus protects internet entry but leaves sensitive research servers open to every internal department.

Question 1191

An analyst finds a malware alert for a file already deleted and needs to determine which other hosts executed it. Which Cisco security control or operational response BEST addresses the stated need?

  1. Maintain managed device inventory with ownership, encryption, update, and enrollment policies before granting enterprise application access.
  2. Respond to changing file disposition by tracing historical file activity and isolating or remediating affected endpoints where warranted.
  3. Scope endpoint detection exclusions narrowly and verify business application behavior after updates without disabling broad antimalware protections.
  4. Isolate high-risk endpoints using approved EDR response while preserving evidence and controlled paths for incident handling.

Explanation

Correct Answer

B:

Respond to changing file disposition by tracing historical file activity and isolating or remediating affected endpoints where warranted. This control addresses the failure mechanism and narrows the enforcement boundary. Cloud malware intelligence can change a file verdict after initial observation; earlier clean classification should not prevent retrospective investigation. Confirm pre-change conditions using: Inspect original file hash, current cloud disposition, execution history, file trajectory, and response capability. Situation: An analyst finds a malware alert for a file already deleted and needs to determine which other hosts executed it.

Incorrect Answers

A:

Maintain managed device inventory with ownership, encryption, update, and enrollment policies before granting enterprise application access. This response applies to MDM device enrollment and inventory, not the controlling requirement in this case. A managed device inventory links technical posture to accountability; simply knowing an IP address does not establish device trust. For this scenario, the targeted action is: Respond to changing file disposition by tracing historical file activity and isolating or remediating affected endpoints where warranted. Situation: An analyst finds a malware alert for a file already deleted and needs to determine which other hosts executed it.

C:

Scope endpoint detection exclusions narrowly and verify business application behavior after updates without disabling broad antimalware protections. This response applies to Secure Endpoint response exclusions and policy safety, not the controlling requirement in this case. Broad folder or process exclusions can create lasting blind spots; false-positive tuning requires evidence and defined review dates. For this scenario, the targeted action is: Respond to changing file disposition by tracing historical file activity and isolating or remediating affected endpoints where warranted. Situation: An analyst finds a malware alert for a file already deleted and needs to determine which other hosts executed it.

D:

Isolate high-risk endpoints using approved EDR response while preserving evidence and controlled paths for incident handling. This response applies to Endpoint incident isolation and forensics, not the controlling requirement in this case. Endpoint isolation contains spread but can interrupt critical operations; response must balance urgency, containment scope, and evidence preservation. For this scenario, the targeted action is: Respond to changing file disposition by tracing historical file activity and isolating or remediating affected endpoints where warranted. Situation: An analyst finds a malware alert for a file already deleted and needs to determine which other hosts executed it.

Question 1192

An incident-response team revokes a compromised key but discovers that no application rotation procedure was tested. Which TWO complementary steps provide the most defensible remediation and its supporting assessment? Select TWO.

  1. Inspect vendor resource types, identity federation, policy inheritance, enforcement integration, and drift reports.
  2. Inspect storage encryption policy, customer-managed key dependencies, rotation schedule, secret locations, and access logs.
  3. Use Cisco Multicloud Defense concepts to define controlled ingress, egress, and workload traffic inspection across supported cloud networks.
  4. Secure cloud workloads and data with appropriate encryption, managed key access, and explicit ownership of secret rotation and runtime use.
  5. A critical vulnerable dependency blocks promotion and approved remediation produces an auditable releasable artifact.

Explanation

Correct Answers

B:

Inspect storage encryption policy, customer-managed key dependencies, rotation schedule, secret locations, and access logs. This checks the relevant condition before an engineer modifies production access or detection behavior. Encryption protects data against unauthorized reading but does not substitute for IAM; key lifecycle management and backups require explicit ownership. The controlled response would be: Secure cloud workloads and data with appropriate encryption, managed key access, and explicit ownership of secret rotation and runtime use. This supplies the diagnostic evidence needed for the complementary action. Situation: An incident-response team revokes a compromised key but discovers that no application rotation procedure was tested.

D:

Secure cloud workloads and data with appropriate encryption, managed key access, and explicit ownership of secret rotation and runtime use. This control addresses the failure mechanism and narrows the enforcement boundary. Encryption protects data against unauthorized reading but does not substitute for IAM; key lifecycle management and backups require explicit ownership. Confirm pre-change conditions using: Inspect storage encryption policy, customer-managed key dependencies, rotation schedule, secret locations, and access logs. This is the implementation portion of the complementary pair. Situation: An incident-response team revokes a compromised key but discovers that no application rotation procedure was tested.

Incorrect Answers

A:

Inspect vendor resource types, identity federation, policy inheritance, enforcement integration, and drift reports. This step could matter for Multicloud identity and centralized policy governance but is not part of the required complementary pair for this case. The paired steps are: Secure cloud workloads and data with appropriate encryption, managed key access, and explicit ownership of secret rotation and runtime use. and Inspect storage encryption policy, customer-managed key dependencies, rotation schedule, secret locations, and access logs. Situation: An incident-response team revokes a compromised key but discovers that no application rotation procedure was tested.

C:

Use Cisco Multicloud Defense concepts to define controlled ingress, egress, and workload traffic inspection across supported cloud networks. This step could matter for Cisco Multicloud Defense traffic policy but is not part of the required complementary pair for this case. The paired steps are: Secure cloud workloads and data with appropriate encryption, managed key access, and explicit ownership of secret rotation and runtime use. and Inspect storage encryption policy, customer-managed key dependencies, rotation schedule, secret locations, and access logs. Situation: An incident-response team revokes a compromised key but discovers that no application rotation procedure was tested.

E:

A critical vulnerable dependency blocks promotion and approved remediation produces an auditable releasable artifact. 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: Secure cloud workloads and data with appropriate encryption, managed key access, and explicit ownership of secret rotation and runtime use. and Inspect storage encryption policy, customer-managed key dependencies, rotation schedule, secret locations, and access logs. Situation: An incident-response team revokes a compromised key but discovers that no application rotation procedure was tested.

Question 1193

A remote security appliance sends detailed authentication logs over an unprotected management network. Before changing security policy, what evidence should the engineer examine FIRST?

  1. Inspect endpoint identity assignments, VLAN membership, SGT propagation, trustsec matrix rules, and routed reachability.
  2. Review syslog destinations, transport security, facility and severity filters, log loss, NTP synchronization, and collector permissions.
  3. Inspect TLS handshake metadata permitted by policy, flow statistics, DNS logs, endpoint process telemetry, and detection confidence.
  4. Inspect SSH/HTTPS management services, NETCONF or RESTCONF configuration, model schema, access roles, and operation results.

Explanation

Correct Answer

B:

Review syslog destinations, transport security, facility and severity filters, log loss, NTP synchronization, and collector permissions. This checks the relevant condition before an engineer modifies production access or detection behavior. Central logging loses forensic value when clocks disagree or records are dropped; authenticated time and secure logging improve evidence quality. The controlled response would be: Forward security event logs over approved protected transport and synchronize clocks for reliable multi-device incident reconstruction. Situation: A remote security appliance sends detailed authentication logs over an unprotected management network.

Incorrect Answers

A:

Inspect endpoint identity assignments, VLAN membership, SGT propagation, trustsec matrix rules, and routed reachability. This evidence addresses VLAN segmentation and SGT policy; it would not establish the primary issue here. The diagnostic evidence needed for this scenario is: Review syslog destinations, transport security, facility and severity filters, log loss, NTP synchronization, and collector permissions. Situation: A remote security appliance sends detailed authentication logs over an unprotected management network.

C:

Inspect TLS handshake metadata permitted by policy, flow statistics, DNS logs, endpoint process telemetry, and detection confidence. This evidence addresses Encrypted network telemetry and correlated detection; it would not establish the primary issue here. The diagnostic evidence needed for this scenario is: Review syslog destinations, transport security, facility and severity filters, log loss, NTP synchronization, and collector permissions. Situation: A remote security appliance sends detailed authentication logs over an unprotected management network.

D:

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: Review syslog destinations, transport security, facility and severity filters, log loss, NTP synchronization, and collector permissions. Situation: A remote security appliance sends detailed authentication logs over an unprotected management network.

Question 1194

A newly deployed SNMPv3 user can authenticate but privacy negotiation fails after the device cipher settings change. Before changing security policy, what evidence should the engineer examine FIRST?

  1. Inspect SSH/HTTPS management services, NETCONF or RESTCONF configuration, model schema, access roles, and operation results.
  2. Inspect SNMP user groups, auth/priv settings, engine IDs, management ACLs, and failed polling logs.
  3. Inspect peer public addresses, IKE/IPsec proposals, NAT treatment, interesting traffic, and security association counters.
  4. Inspect authentication attempts, command-set policies, server reachability, shared secrets, and accounting records.

Explanation

Correct Answer

B:

Inspect SNMP user groups, auth/priv settings, engine IDs, management ACLs, and failed polling logs. This checks the relevant condition before an engineer modifies production access or detection behavior. SNMPv3 supports integrity and encryption for management queries when authPriv is configured; SNMPv1 community strings do not provide equivalent protection. The controlled response would be: Use SNMPv3 with authentication and privacy where appropriate and restrict agents to approved management sources and read views. Situation: A newly deployed SNMPv3 user can authenticate but privacy negotiation fails after the device cipher settings change.

Incorrect Answers

A:

Inspect SSH/HTTPS management services, NETCONF or RESTCONF configuration, model schema, access roles, and operation results.

D:

Inspect authentication attempts, command-set policies, server reachability, shared secrets, and accounting records. This evidence addresses TACACS+ administration authorization; it would not establish the primary issue here. The diagnostic evidence needed for this scenario is: Inspect SNMP user groups, auth/priv settings, engine IDs, management ACLs, and failed polling logs. Situation: A newly deployed SNMPv3 user can authenticate but privacy negotiation fails after the device cipher settings change.

Question 1195

A microservice copies a long-lived cloud administrator key into every replica for convenience. Which TWO complementary steps provide the most defensible remediation and its supporting assessment? Select TWO.

  1. Inspect OAuth app grants, external collaboration settings, admin roles, account lifecycle, and cloud sharing audit logs.
  2. Inspect image signatures or digests, container service accounts, secrets mounts, node permissions, and east-west traffic.
  3. Protect container workloads with approved image provenance, minimal privileges, network boundaries, and runtime monitoring.
  4. Misconfigured public resources are detected and controlled while approved exceptions remain documented and reviewed.
  5. Use appropriately supported eBPF-based observation to understand process and network activity without assuming kernel hooks enforce every application policy.

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 microservice copies a long-lived cloud administrator key into every replica for convenience.

Question 1196

A finance laptop uploads gigabytes of customer reports to a personal cloud drive after hours. Which observed result BEST confirms that the security requirement is met?

  1. A staged exfiltration simulation is distinguished from legitimate DNS traffic and the responsible endpoint is investigated.
  2. A test high-confidence threat generates one attributable case and a documented approved response without duplicate unsafe playbook actions.
  3. An unauthorized sensitive export is detected and blocked or escalated while approved business uploads remain permitted.
  4. An unknown IoT printer receives a restrictive authorization pending verification rather than unconditional internal access.

Explanation

Correct Answer

C:

An unauthorized sensitive export is detected and blocked or escalated while approved business uploads remain permitted. This is an observable acceptance condition, rather than an assumption that enabling a feature alone proves security. HTTPS encryption does not prove the destination or data transfer is authorized; flow, SaaS policy, and endpoint context can reveal risk without blindly decrypting all traffic. Situation: A finance laptop uploads gigabytes of customer reports to a personal cloud drive after hours.

Incorrect Answers

A:

A staged exfiltration simulation is distinguished from legitimate DNS traffic and the responsible endpoint is investigated. This outcome tests DNS tunneling exfiltration detection and is not sufficient proof of the stated requirement. Here the relevant validation is: An unauthorized sensitive export is detected and blocked or escalated while approved business uploads remain permitted. Situation: A finance laptop uploads gigabytes of customer reports to a personal cloud drive after hours.

B:

A test high-confidence threat generates one attributable case and a documented approved response without duplicate unsafe playbook actions. This outcome tests Splunk event orchestration and response workflows and is not sufficient proof of the stated requirement.

Situation: A finance laptop uploads gigabytes of customer reports to a personal cloud drive after hours.

D:

An unknown IoT printer receives a restrictive authorization pending verification rather than unconditional internal access. This outcome tests Cisco ISE profiling and endpoint identity certainty and is not sufficient proof of the stated requirement. Here the relevant validation is: An unauthorized sensitive export is detected and blocked or escalated while approved business uploads remain permitted. Situation: A finance laptop uploads gigabytes of customer reports to a personal cloud drive after hours.

Question 1197

A remote employee's laptop stops reporting compliance after weeks offline yet retains privileged SaaS access. Before changing security policy, what evidence should the engineer examine FIRST?

  1. Inspect email platform, API permissions, journaling architecture, allowed mail-flow changes, product entitlement, and required remediation actions.
  2. Inspect last posture evaluation time, policy change triggers, endpoint alert status, session authorization, and remediation evidence.
  3. Inspect OS patch level, installed applications, configuration baselines, exception evidence, and last check-in.
  4. Inspect MDM enrollment status, device serial identifiers, operating system version, policy compliance, and assigned owner.

Explanation

Correct Answer

C:

Inspect OS patch level, installed applications, configuration baselines, exception evidence, and last check-in. This checks the relevant condition before an engineer modifies production access or detection behavior. Device management can deploy settings and collect compliance status; a successful enrollment alone does not prove ongoing patch health. The controlled response would be: Use supported device management controls to enforce software update, application inventory, and secure configuration requirements for endpoints. Situation: A remote employee's laptop stops reporting compliance after weeks offline yet retains privileged SaaS access.

Incorrect Answers

A:

Inspect email platform, API permissions, journaling architecture, allowed mail-flow changes, product entitlement, and required remediation actions.

This evidence addresses MDM device enrollment and inventory; it would not establish the primary issue here. The diagnostic evidence needed for this scenario is: Inspect OS patch level, installed applications, configuration baselines, exception evidence, and last check-in. Situation: A remote employee's laptop stops reporting compliance after weeks offline yet retains privileged SaaS access.

Question 1198

A rogue laptop imports an unrelated public certificate and expects it to grant campus network admission. Which TWO complementary steps provide the most defensible remediation and its supporting assessment? Select TWO.

  1. Guests obtain only appropriate internet access while enrolled employees reach approved internal applications under auditable policy.
  2. Enforce network access requirements for device OS, required security controls, and application compliance, with remediation for failures.
  3. Inspect current session identity, NAD CoA support and shared secret, ISE authorization change, and RADIUS live logs.
  4. Inspect issuing CA trust, certificate subject and EKU, expiry, device records, policy match, and failed EAP logs.
  5. Use certificates and role-aware policy to distinguish approved managed devices from unknown or noncompliant devices during network onboarding.

Explanation

Correct Answers

D:

Inspect issuing CA trust, certificate subject and EKU, expiry, device records, policy match, and failed EAP logs. This checks the relevant condition before an engineer modifies production access or detection behavior. Device certificate authentication verifies a credential but does not on its own guarantee security software or configuration compliance. The controlled response would be: Use certificates and role-aware policy to distinguish approved managed devices from unknown or noncompliant devices during network onboarding. This supplies the diagnostic evidence needed for the complementary action. Situation: A rogue laptop imports an unrelated public certificate and expects it to grant campus network admission.

E:

Use certificates and role-aware policy to distinguish approved managed devices from unknown or noncompliant devices during network onboarding.

  2. Inspect protected data lifetimes, protocol suites, key sizes, certificate dependencies, crypto inventory, and approved algorithm policies.
  3. Examine flow spikes, source distributions, server resource graphs, load-balancer logs, and endpoint execution telemetry.
  4. Inspect server certificate SAN, chain trust, expiry and revocation status, negotiated protocol, and handshake errors.

Explanation

Correct Answer

D:

Inspect server certificate SAN, chain trust, expiry and revocation status, negotiated protocol, and handshake errors. This checks the relevant condition before an engineer modifies production access or detection behavior. Encryption without authenticated identity does not rule out interception; certificates bind a public key to a verified name under a trust chain. The controlled response would be: Validate peer identity with a trusted certificate chain, correct hostname, certificate validity, and appropriate TLS policy before exchanging sensitive data. Situation: A security gateway's TLS inspection fails because the enterprise trust anchor was not deployed to managed clients.
