Google Cloud Professional Cloud Network Engineer — Question 74

One instance in your VPC is configured to run with a private IP address only. You want to ensure that even if this instance is deleted, its current private IP address will not be automatically assigned to a different instance.
In the GCP Console, what should you do?

Answer options

• A. Assign a public IP address to the instance.
• B. Assign a new reserved internal IP address to the instance.
• C. Change the instance's current internal IP address to static.
• D. Add custom metadata to the instance with key internal-address and value reserved.

Correct answer: C

Explanation

The correct answer is C because changing the internal IP address to static ensures it remains assigned to the instance until you explicitly release it. Options A and B do not address the requirement of retaining the private IP address, while option D does not guarantee that the IP address will not be reassigned.
