Google Professional Cloud Network Engineer Question 140
Single answerGoogle Cloud PlatformYour organization has a hybrid cloud setup where multiple on-premises data centers connect to your Google Cloud environment via Cloud VPN. You have deployed a few Compute Engine instances across three regions: us-central1, europe-west1, and asia-east1. These instances need to communicate with each other and with the on-premises systems. To ensure optimal routing and reduced latency, what dynamic routing mode should you select for your Cloud Router configuration?
- A
Regional dynamic routing
- B
Global dynamic routing
- C
Static routing
- D
Custom dynamic routing
Show answer and explanation
Correct answer: B
Explanation
In this scenario, the organization needs seamless communication between instances in different regions and with on-premises systems. Global dynamic routing allows Cloud Routers to share routes across all regions in Google Cloud, ensuring optimal connectivity and simplicity in managing the network. Therefore, global dynamic routing is the best choice.
- A. Incorrect.
Regional dynamic routing limits route advertisements to only the specific region where the Cloud Router is deployed. This would not allow cross-region communication without additional configurations, making it unsuitable for this scenario.
- B. Correct.
Global dynamic routing allows route advertisements across all regions in Google Cloud, enabling seamless cross-region communication. This is the ideal choice for the given hybrid cloud setup.
- C. Incorrect.
Static routing does not use a Cloud Router and would require manual configuration for all possible routes. This is not scalable or efficient for the described environment.
- D. Incorrect.
Custom dynamic routing is not a valid Google Cloud feature. The correct options are limited to regional or global dynamic routing modes.
