Google Professional Cloud Network Engineer Question 138
Single answerGoogle Cloud PlatformYou are designing a hybrid environment where your on-premises data center connects to multiple Virtual Private Cloud (VPC) networks in Google Cloud using Cloud VPN. Your organization has offices in both Europe and North America, and you want the on-premises data center to be able to dynamically access resources in both regions. The North American region hosts a critical application that must have minimal latency. How should you configure dynamic routing to meet these requirements?
- A
Use regional dynamic routing mode for both VPC networks.
- B
Use global dynamic routing mode for both VPC networks.
- C
Use global dynamic routing mode for the North American VPC and regional dynamic routing mode for the European VPC.
- D
Use regional dynamic routing mode for the North American VPC and global dynamic routing mode for the European VPC.
Show answer and explanation
Correct answer: B
Explanation
To enable dynamic routing of on-premises resources across multiple regions, you must use global dynamic routing mode. This ensures that routes learned through Cloud VPN or interconnect connections are shared across all regions. Regional dynamic routing restricts route propagation to a single region, which would not meet the requirement to access resources in both Europe and North America.
- A. Incorrect.
Using regional dynamic routing limits the scope of dynamic routes to the region where the VPN gateway is located. This would not allow the on-premises data center to dynamically access resources across regions.
- B. Correct.
Global dynamic routing mode allows dynamic routes to be propagated across all regions, ensuring that the on-premises data center can dynamically access resources in both North America and Europe. This minimizes latency and meets connectivity requirements.
- C. Incorrect.
Using a mix of global and regional dynamic routing modes is not supported. All VPC networks must use the same dynamic routing mode (either regional or global).
- D. Incorrect.
Using a mix of global and regional dynamic routing modes is not supported. All VPC networks must use the same dynamic routing mode (either regional or global).
