Question 150
At the Hillcrest research lab, device administrators authenticate successfully and use permitted commands, but the security team cannot reconstruct who ran a sensitive configuration command. Which operational change most directly addresses the fault described?
Explanation
Correct Answer
The fault at the Hillcrest research lab has a specific cause. Authentication and authorization are active, but command-level accounting records are not being collected. Enable and verify AAA command accounting with a reachable, trusted logging/accounting destination. Confirm success against this result: The test command produces an attributable record with identity, action and time at the accounting service.
Incorrect Answers
This is appropriate for a different routing or network-control issue: A rogue DHCPv6 responder can influence hosts even when router advertisements are controlled separately. The stated evidence at the Hillcrest research lab instead concerns aaa accounting gaps.
This could help where copp protocol classification error is the issue, but not for the evidence reported at the Hillcrest research lab. Authentication and authorization are active, but command-level accounting records are not being collected.
That change targets copp control-plane bgp drops, not the reported aaa accounting gaps fault at the Hillcrest research lab. Authentication and authorization are active, but command-level accounting records are not being collected.
