Question 70
At a distributed Cisco ISE deployment, a security review finds: A technician wants to use zero-touch provisioning to modify every already-running ISE node's authorization policies, bypassing PAN change control. Which ongoing practice is most appropriate for this failure mode?
Explanation
Correct Answer
Separate initial-node bootstrap rights from production policy-administration privileges. This control addresses recurrence of the observed failure. The governing behavior is: Provisioning bootstrap and steady-state distributed policy management solve different lifecycle tasks. The ongoing acceptance check remains: The new node is bootstrapped with its intended system settings while existing authorization policies change only through approved PAN operations.
Incorrect Answers
Separate initial-node bootstrap rights from production policy-administration privileges. The offered choice instead concerns a different principle: Add DNS and NTP acceptance tests to the automated provisioning pipeline. Those technical conditions are not interchangeable.
Separate initial-node bootstrap rights from production policy-administration privileges. The offered choice instead concerns a different principle: Protect provisioning files, rotate temporary secrets, and audit bootstrap access after onboarding. Those technical conditions are not interchangeable.
Separate initial-node bootstrap rights from production policy-administration privileges. The offered choice instead concerns a different principle: one laboratory node manages policy, answers test RADIUS requests, and records corresponding live logs. Those technical conditions are not interchangeable.
