Google Professional Cloud Network Engineer Question 158
Single answerGoogle Cloud PlatformYour organization is setting up a hybrid cloud architecture on Google Cloud. The on-premises environment uses the IP range 10.0.0.0/16. You are tasked with designing the IP address space for a new VPC on Google Cloud to ensure no IP address conflicts occur between the two environments. Which IP address range should you assign to the Google Cloud VPC?
- A
10.0.0.0/16
- B
192.168.1.0/24
- C
172.16.0.0/16
- D
10.1.0.0/16
Show answer and explanation
Correct answer: D
Explanation
When designing IP address spaces in a hybrid cloud setup, it is crucial to avoid IP address conflicts between on-premises and cloud environments. The on-premises environment uses 10.0.0.0/16, so the Google Cloud VPC must use a non-overlapping range. 10.1.0.0/16 is a suitable choice because it avoids conflict, uses a private IP range, and provides sufficient address space for the VPC.
- A. Incorrect.
This option conflicts directly with the on-premises IP range (10.0.0.0/16). Using this range would lead to IP overlap issues.
- B. Incorrect.
This option is valid in terms of avoiding overlap with the on-premises environment, but the range (192.168.1.0/24) is too small for most VPCs in hybrid setups, which typically require larger address spaces.
- C. Incorrect.
Although this option avoids overlap with the on-premises IP range, it uses a private IP range that might also conflict with other networks in the organization. It is not the best choice without further context.
- D. Correct.
This option avoids IP conflicts with the on-premises IP range and provides a sufficient and commonly used private IP range for the Google Cloud VPC.
