Google Professional Cloud Network Engineer Question 80
Select 3Google Cloud PlatformYou are designing a hybrid cloud network for a company that operates in multiple regions and requires low-latency access to on-premises resources. The company plans to migrate some workloads to Google Cloud and uses a mix of IPv4 and IPv6 addresses. They also want to bring their own IP (BYOIP) for certain public-facing workloads to maintain consistency with their existing DNS. Which considerations should you include in your IP address management strategy for this architecture?
- A
Ensure that subnets in each VPC do not overlap and align with the company's existing IP address plan.
- B
Use Shared VPC to centrally manage IP address allocation across all projects.
- C
Enable IPv6 for all subnets in Google Cloud to support dual-stack networking.
- D
Reserve public IP ranges for BYOIP in the Google Cloud project and configure routes for these ranges.
- E
Configure private Google Access to enable communication between on-premises systems and Google Cloud services.
- F
Use Cloud NAT to provide outbound internet access for private instances in the VPC.

Correct answers: A, B, D
Explanation
Designing an IP address management strategy for a hybrid cloud network involves avoiding IP conflicts, centralizing management for scalability, and accommodating special requirements like BYOIP. Ensuring non-overlapping subnets, leveraging Shared VPC for centralized management, and reserving public IP ranges for BYOIP are critical steps in meeting the company's needs. While options like enabling IPv6, Private Google Access, and Cloud NAT are useful in specific contexts, they do not directly address the scenario's requirements.
- A. Correct.
Correct: Ensuring that subnets do not overlap and align with the company's existing IP address plan is critical for avoiding routing conflicts in a hybrid network.
- B. Correct.
Correct: Using Shared VPC allows centralized management of IP address allocation and networking, which is especially useful for multi-project environments.
- C. Incorrect.
Incorrect: While enabling IPv6 may be beneficial, it is not strictly necessary for the given requirements. The scenario specifies a mix of IPv4 and IPv6, so dual-stack networking is optional.
- D. Correct.
Correct: Reserving public IP ranges for BYOIP and configuring routes ensures that the company can use their existing IP addresses for public-facing workloads.
- E. Incorrect.
Incorrect: Private Google Access is used for private instances to access Google services, but it is unrelated to the BYOIP requirement or subnet planning in this scenario.
- F. Incorrect.
Incorrect: Cloud NAT provides outbound internet access for private instances, but it is not relevant to the IP address management strategy in this scenario.
