Practice Test 2 | Google Cloud Certified Professional Cloud Network Engineer | Dumps | Mock Test
A company would like to retain the current internal IP address on its GCE instance to meet certain security obligations of having a static IP address for certain application.
Which of the following is the least disruptive actions to achieve this?
A. Stop and restart the instances with a new static internal IP addresses.
B. Terminate the instances and recreate the instances with static IP addresses.
C. Change the current ephemeral IP to a static IP using the console or cli
D. Assign the instance a new static IP and remove the current static internal IP.
Answer: C
Option A is incorrect because stopping and restarting an instance doesn’t change the internal IP address neither does it change an ephemeral IP to a static one.
Option B is incorrect as this is disruptive to the availability of the application.
Option C is correct, this is the least disruptive action to achieve the task.
Option D is incorrect. This action is impossible
