Google Professional Cloud Network Engineer Question 136
Single answerGoogle Cloud PlatformYour organization has multiple VPC networks spanning different Google Cloud regions. These VPCs are interconnected using Cloud VPN gateways. You want to dynamically exchange route information between regions and ensure that route propagation works across all regions without additional manual configuration. Which dynamic routing mode should you select for your Cloud Router configuration?
- A
Regional dynamic routing
- B
Global dynamic routing
- C
Static routing
- D
Custom route advertisements
Show answer and explanation
Correct answer: B
Explanation
To exchange route information dynamically across multiple regions, the global dynamic routing mode is required. This mode allows Cloud Routers to propagate routes between regions automatically, meeting the organization's requirement for seamless route exchange without manual configuration.
- A. Incorrect.
Regional dynamic routing allows route propagation only within the same region as the Cloud Router. This does not meet the requirement to exchange route information across multiple regions.
- B. Correct.
Global dynamic routing enables route propagation between VPC networks across different regions. This is the correct choice to allow dynamic exchange of routes across all regions.
- C. Incorrect.
Static routing is a manual process and does not involve dynamic propagation of routes, which is essential in this scenario.
- D. Incorrect.
Custom route advertisements allow you to manually configure which routes are advertised by a Cloud Router, but this does not enable dynamic exchange of route information across regions.
