Google Professional Cloud Network Engineer Question 121
Single answerGoogle Cloud PlatformYour organization has multiple branch offices that need to securely connect to a centralized application running in Google Cloud. The branch offices have different internet service providers and require reliable, encrypted connectivity. You want a solution that minimizes configuration overhead and supports dynamic routing. Which option should you choose?
- A
Set up a Cloud VPN with dynamic routing using BGP
- B
Implement a Cloud Interconnect for each branch office
- C
Use SD-WAN appliances at each branch to connect to Google Cloud
- D
Configure multiple static VPN tunnels with manual routing
Show answer and explanation
Correct answer: A
Explanation
Cloud VPN with dynamic routing using BGP is the best option for securely connecting branch offices to Google Cloud. It provides encrypted connections over public internet and supports dynamic routing, reducing manual configuration and ensuring reliable connectivity even as network routes change.
- A. Correct.
This is the correct answer. Cloud VPN with dynamic routing using BGP allows for secure, encrypted connections and supports dynamic routing, which reduces the need for manual configuration when routes change.
- B. Incorrect.
Cloud Interconnect is designed for high-bandwidth, low-latency private connectivity between on-premises data centers and Google Cloud. It is not cost-effective or suitable for branch office connectivity over public internet.
- C. Incorrect.
While SD-WAN appliances can provide branch office connectivity, they typically require additional hardware and management complexity. They are not natively integrated with Google Cloud services.
- D. Incorrect.
Static VPN tunnels with manual routing require significant configuration overhead and do not adapt easily to network changes, making them less suitable for branch office connectivity with dynamic needs.
