Google Professional Cloud Network Engineer Question 139
Single answerGoogle Cloud PlatformYour organization has a multi-region architecture in Google Cloud and uses Cloud VPN to connect on-premises networks to the cloud. You want to share dynamic routes learned from one region's VPN to another region's VPN without manually configuring static routes. Which dynamic routing mode should you select to meet this requirement?
- A
Regional dynamic routing
- B
Global dynamic routing
- C
Static routing
- D
Custom dynamic routing
Show answer and explanation
Correct answer: B
Explanation
Global dynamic routing is specifically designed to propagate dynamic routes across multiple Google Cloud regions. This capability is essential for multi-region architectures where you want to share routes learned from one region's Cloud VPN to another without manual intervention. Regional dynamic routing, on the other hand, restricts route sharing to a single region, making it unsuitable for this scenario.
- A. Incorrect.
Regional dynamic routing limits the propagation of dynamic routes to resources within the same region. It cannot share routes between regions, which does not meet the multi-region requirement in this scenario.
- B. Correct.
Global dynamic routing allows dynamic routes to be shared across regions, making it the correct choice for multi-region architecture.
- C. Incorrect.
Static routing requires manual configuration and does not support the automatic propagation of dynamic routes between regions. This does not satisfy the requirement.
- D. Incorrect.
Custom dynamic routing is not a valid configuration option in Google Cloud. This is an incorrect choice.
