Google Professional Cloud Network Engineer Question 249
Single answerGoogle Cloud PlatformYou are designing a hybrid network for your company, which has multiple on-premises locations and Google Cloud resources distributed across different regions. You want to ensure that dynamic routes learned from your Cloud VPN gateways and interconnects are available globally within your Virtual Private Cloud (VPC) network. What should you do to achieve this?
- A
Enable global dynamic routing on the VPC network.
- B
Enable regional dynamic routing on the VPC network.
- C
Create separate VPCs for each region and configure peering to share routes.
- D
Use static routes instead of dynamic routing for global route distribution.
Show answer and explanation
Correct answer: A
Explanation
To enable global propagation of dynamic routes learned via Cloud VPN or interconnects across all regions in a VPC, you must configure the VPC to use global dynamic routing. This is critical for hybrid network setups that span multiple regions and require seamless connectivity between on-premises resources and cloud resources in different regions.
- A. Correct.
Correct. Enabling global dynamic routing ensures that dynamic routes learned from VPN gateways and interconnects are propagated across all regions within the VPC network.
- B. Incorrect.
Incorrect. Regional dynamic routing restricts the learned dynamic routes to the same region where the router is located, and does not support global route propagation.
- C. Incorrect.
Incorrect. Creating separate VPCs and using peering does not provide global route distribution for dynamic routes. Peering does not support the propagation of dynamic routes.
- D. Incorrect.
Incorrect. Static routes are not scalable or efficient for dynamic route distribution, especially in a globally distributed network.
