Google Professional Cloud Network Engineer Question 233
Select 3Google Cloud PlatformYour company’s Google Cloud environment includes a VPC with a subnet in the 'us-central1' region using the CIDR range 10.0.0.0/24. Due to increased demand, the subnet is running out of available IP addresses. You have been tasked with expanding the subnet range to accommodate more resources. Which of the following steps are required to successfully expand the subnet range?
- A
Edit the existing subnet to expand the CIDR range, ensuring the new range does not overlap with any existing subnets in the VPC.
- B
Delete the existing subnet and recreate it with a larger CIDR range to ensure compatibility.
- C
Verify that no resources are actively using the existing subnet before expanding the range.
- D
Ensure that the new CIDR range falls within the VPC’s IP address range.
- E
Update firewall rules and routes if needed to account for the new IP range.
Show answer and explanation
Correct answers: A, D, E
Explanation
In Google Cloud, expanding a VPC subnet range is a straightforward process that involves editing the existing subnet to include the new CIDR range. The new range must not overlap with other subnets in the VPC and must fall within the VPC’s overall IP range. It is not necessary to delete and recreate the subnet or verify resource usage beforehand. After expanding the range, you should review and update any dependent configurations, such as firewall rules and routes, to ensure continued functionality.
- A. Correct.
Correct. You can edit an existing subnet in a VPC to expand its CIDR range, provided the new range does not overlap with other subnets in the same VPC.
- B. Incorrect.
Incorrect. It is not necessary to delete and recreate the subnet. Google Cloud allows you to expand the CIDR range of an existing subnet without disruption.
- C. Incorrect.
Incorrect. It is not required to verify resource usage before expanding the subnet range. Expanding the range is a non-disruptive operation.
- D. Correct.
Correct. The new subnet range must fall within the overall IP address range of the VPC.
- E. Correct.
Correct. Firewall rules and routes might need to be updated to account for the expanded range, depending on your network configuration.
