Question 290
A network access incident review reveals: A regional administrator tries to write new policy when the Primary Administration Node has failed, assuming the secondary administration node automatically accepts writes without role promotion. Which maintenance practice most directly limits the same risk?
Explanation
Correct Answer
This safeguard directly addresses ise secondary administration failover procedure: Exercise promotion and restoration procedures, document node status, and avoid simultaneous competing administrative primaries. The risk being prevented is: The secondary administration persona is a standby policy management node until the appropriate supported promotion or administrative failover workflow makes it primary. A safeguard aimed at another fault would not control this issue.
Incorrect Answers
Policy authoring and configuration management are functions of the Policy Administration Node persona, not the policy service persona that handles endpoint requests. “Document persona ownership, restrict administrative access to the PAN, and verify configuration replication after every policy change” would remedy that alternative situation, but it would not correct the present issue: the secondary administration persona is a standby policy management node until the appropriate supported promotion or administrative failover workflow makes it primary.
“Validate PSN latency, certificate trust, and per-site RADIUS server ordering before wide access-control rollout” is the supported response when policy Service Nodes process RADIUS authentication and authorization near access devices; a distant request path increases dependency on WAN delay and reachability. Here the decisive response is “Exercise promotion and restoration procedures, document node status, and avoid simultaneous competing administrative primaries”, so that different intervention does not meet the stated requirement.
Cisco ISE virtual sizing and supported resource reservations affect processing capacity, so merely booting an undersized VM is not proof of a supported design. “Review expected endpoints, authentication bursts, personas, and virtualization overcommitment before choosing a hardware or VM profile” applies to that other condition. The reported evidence is a regional administrator tries to write new policy when the Primary Administration Node has failed, assuming the secondary administration node automatically accepts writes without role promotion; this alternative would address the wrong dependency.
