Google Professional Cloud Network Engineer Question 240
Single answerGoogle Cloud PlatformYou are tasked with setting up network connectivity between two Virtual Private Cloud (VPC) networks: VPC-A and VPC-B. VPC-A hosts a custom application that requires low-latency connectivity to a database in VPC-B. Both VPCs use non-overlapping IP ranges. You decide to use Cloud VPN to establish the connection. Which routing method should you configure to ensure scalability and minimal manual updates for future network changes?
- A
Static routing with custom route entries
- B
Dynamic routing using Cloud Router
- C
Static routing using Google Cloud Console
- D
Dynamic routing using manually defined BGP configurations
Show answer and explanation
Correct answer: B
Explanation
Dynamic routing using Cloud Router is the most suitable option for connecting VPCs using Cloud VPN. Cloud Router automates the exchange of routes between VPCs, ensuring scalability and reducing the need for manual updates when subnets or IP ranges change. This approach is ideal for scenarios where future network growth is anticipated, as it minimizes administrative overhead.
- A. Incorrect.
Static routing with custom route entries requires manual configuration for each route, which is not scalable for future changes or additional subnets.
- B. Correct.
Dynamic routing using Cloud Router allows automatic route exchange between VPCs, making it a scalable and efficient solution for future network modifications.
- C. Incorrect.
Static routing using Google Cloud Console faces the same limitations as other static routing methods, requiring manual updates to routes.
- D. Incorrect.
Dynamic routing using manually defined BGP configurations is not applicable in this scenario because Cloud Router simplifies BGP configuration, and manual BGP setup is not required in Google Cloud.
