Google Professional Cloud Network Engineer Question 232
Select 3Google Cloud PlatformYou are managing a Virtual Private Cloud (VPC) in Google Cloud and need to expand the IP range of an existing subnet to accommodate additional workloads. Which of the following steps or considerations are correct when performing this task?
- A
The new IP range must not overlap with any existing subnets in the same VPC.
- B
The subnet expansion cannot be performed if there are active VM instances using the subnet.
- C
You can only expand the subnet range by adding secondary IP ranges, not by increasing the primary range.
- D
Updating the subnet's primary IP range will not disrupt existing resources using IPs within the original range.
- E
The expanded IP range must fall within the VPC network’s overall CIDR block.
Show answer and explanation
Correct answers: A, D, E
Explanation
When expanding a subnet's IP range in Google Cloud, you must ensure that the new range does not overlap with existing subnets in the same VPC. The change is non-disruptive to existing resources, and you can expand the primary range as long as it adheres to the VPC's CIDR block. These constraints ensure proper routing and address allocation within the VPC.
- A. Correct.
Correct: The new IP range must not overlap with any other subnet in the same VPC, as overlapping IP ranges can cause routing conflicts.
- B. Incorrect.
Incorrect: Subnet expansion can be performed even if there are active VM instances using the subnet. The change is applied without disrupting existing resources.
- C. Incorrect.
Incorrect: You can expand both the primary IP range and add secondary IP ranges. Expanding the primary range is allowed as long as it follows the VPC's constraints.
- D. Correct.
Correct: Updating the subnet's primary IP range does not disrupt existing resources using IPs within the original range, as the original range remains valid.
- E. Correct.
Correct: The expanded IP range must fall within the overall CIDR block of the VPC. This ensures consistency within the network's address space.
