Question 340

The initial implementation fails or does not meet the expected behavior. A security automation needs to quarantine a suspicious endpoint, but the engineer considers deleting all switch port configurations manually. Which investigation should be prioritized to diagnose the problem?

  1. Inspect endpoint path, auth token exchange, pagination and device response fields.
  2. Inspect site ID, device UUID, assignment task status and resulting inventory record.
  3. Inspect endpoint identifier, ISE authorization profile and network device enforcement logs.
  4. Compare sample dependencies, API docs version and actual request/response traces.

Explanation

Correct Answer

C:

Inspect endpoint identifier, ISE authorization profile and network device enforcement logs. These are the relevant initial evidence checks for ISE endpoint policy and posture use. Intended action: Use supported Cisco ISE policy and endpoint APIs or integration to apply the intended authorization response. Expected success condition: The identified endpoint receives the expected restricted access without affecting unrelated clients.

Incorrect Answers

A:

Inspect endpoint path, auth token exchange, pagination and device response fields. This investigation primarily applies to Get device inventory from Catalyst Center, not the current ISE endpoint policy and posture use problem. Prioritize: Inspect endpoint identifier, ISE authorization profile and network device enforcement logs.

B:

Inspect site ID, device UUID, assignment task status and resulting inventory record. This investigation primarily applies to Catalyst Center site hierarchy assignment, not the current ISE endpoint policy and posture use problem. Prioritize: Inspect endpoint identifier, ISE authorization profile and network device enforcement logs.

D:

Compare sample dependencies, API docs version and actual request/response traces. This investigation primarily applies to Choose API documentation over Code Exchange sample, not the current ISE endpoint policy and posture use problem. Prioritize: Inspect endpoint identifier, ISE authorization profile and network device enforcement logs.

Question 341

A Cisco network automation team has this requirement: A SOC tool wants correlated incident information from Cisco XDR, while the current script separately scrapes individual product web pages. Which design or implementation action best addresses it?

  1. Use documented XDR incident APIs with approved scopes to retrieve correlated security context.
  2. Use the documented Catalyst Center site assignment workflow with the site and device identifiers.
  3. Use an Accept header for the documented YANG data media type and an authenticated model resource.
  4. Represent the application policy through ACI endpoint groups and an appropriate contract in APIC.

Explanation

Correct Answer

A:

Use documented XDR incident APIs with approved scopes to retrieve correlated security context. Technical reason: Security orchestration platforms expose normalized incident resources through supported APIs. Verify by: A sample incident includes expected identifiers and linked evidence without HTML scraping. Deployment qualification: Available telemetry depends on connected products and tenant entitlements.

Incorrect Answers

B:

Use the documented Catalyst Center site assignment workflow with the site and device identifiers. This instead targets the different case Catalyst Center site hierarchy assignment. The described Cisco XDR incident context API requirement specifically calls for Use documented XDR incident APIs with approved scopes to retrieve correlated security context.

C:
