Google Professional Cloud Network Engineer Question 248
Single answerGoogle Cloud PlatformYou are designing a multi-region deployment in Google Cloud and need to configure dynamic routing for your Virtual Private Cloud (VPC). Your application requires that all routes from a newly created region are automatically propagated across all other regions in the VPC. What setting should you configure to meet this requirement?
- A
Enable global dynamic routing on the VPC network.
- B
Enable regional dynamic routing on the VPC network.
- C
Configure a Cloud Router in each region to propagate routes manually.
- D
Use static routes for inter-region communication instead of dynamic routing.
Show answer and explanation
Correct answer: A
Explanation
Global dynamic routing allows route propagation across all regions within a VPC, meeting the requirement for automatic propagation of routes from a newly created region to all other regions. Regional dynamic routing, on the other hand, restricts route propagation to a single region, and static routes or manual configurations are not scalable or efficient for this scenario.
- A. Correct.
This is correct. Enabling global dynamic routing ensures that routes learned in one region are automatically propagated to all other regions in the VPC.
- B. Incorrect.
This is incorrect. Regional dynamic routing limits route propagation to within the same region, which does not meet the requirement of propagating routes across all regions.
- C. Incorrect.
This is incorrect. Manually configuring Cloud Routers in each region is unnecessary when global dynamic routing can automate route propagation across regions.
- D. Incorrect.
This is incorrect. Static routes do not meet the requirement of automatically propagating routes and would require manual configuration for every change.
