Question 60
An enterprise access-control incident describes: A factory staging team distributes one zero-touch provisioning file containing the same administrative credentials to several unrelated ISE appliances. What is the key technical principle in this situation?
Explanation
Correct Answer
Reusing bootstrap secrets across appliances increases credential exposure and can bind a node to the wrong identity. This behavior directly governs the stated requirement. The recommended action is: Use per-device approved bootstrap data and protect sensitive configuration material throughout zero-touch provisioning. The acceptance result is: Each staged appliance receives its distinct approved identity and no shared plaintext credentials remain in the delivery workflow.
Incorrect Answers
Add DNS and NTP acceptance tests to the automated provisioning pipeline. The repeat risk here is different: Validate bootstrap DNS, access, and device identity against a clean installation before rollout. A directly relevant preventive control is: Reusing bootstrap secrets across appliances increases credential exposure and can bind a node to the wrong identity.
Protect provisioning files, rotate temporary secrets, and audit bootstrap access after onboarding. The repeat risk here is different: Validate bootstrap DNS, access, and device identity against a clean installation before rollout. A directly relevant preventive control is: Reusing bootstrap secrets across appliances increases credential exposure and can bind a node to the wrong identity.
Monitoring node retains the defined reporting period without disk threshold alerts under a realistic log-rate trial. The repeat risk here is different: Validate bootstrap DNS, access, and device identity against a clean installation before rollout. A directly relevant preventive control is: Reusing bootstrap secrets across appliances increases credential exposure and can bind a node to the wrong identity.
