Google Professional Cloud Network Engineer Question 132
Select 3Google Cloud PlatformYour company has a critical workload running in Google Cloud and needs to ensure high availability and disaster recovery for connectivity between your on-premises data center and Google Cloud. The solution must provide fault tolerance for regional outages and maintain connectivity during failover events with minimal manual intervention. Which of the following connectivity strategies should you implement?
- A
Use Dedicated Interconnect connections in two different Google Cloud regions and configure Border Gateway Protocol (BGP) for automatic failover.
- B
Use a single Partner Interconnect connection in one Google Cloud region and configure static routes for failover.
- C
Deploy HA VPN tunnels in two separate Google Cloud regions and configure dynamic routing with Cloud Router.
- D
Rely on a single Dedicated Interconnect connection and implement manual failover using BGP route priorities.
- E
Use multiple Partner Interconnect connections in different Google Cloud regions and configure dynamic routing with Cloud Router.
Show answer and explanation
Correct answers: A, C, E
Explanation
To design a high-availability and disaster recovery connectivity strategy, it is essential to eliminate single points of failure and ensure fault tolerance for regional outages. Using multiple connections (either Dedicated Interconnect or Partner Interconnect) across regions or HA VPN tunnels provides redundancy. Configuring dynamic routing with BGP or Cloud Router ensures that failover happens automatically without manual intervention. This aligns with the requirement for high availability and minimal manual effort during failover events.
- A. Correct.
This option is correct because having Dedicated Interconnect connections in two different regions provides fault tolerance for regional outages. BGP enables automatic failover, ensuring high availability.
- B. Incorrect.
This option is incorrect because using a single Partner Interconnect connection in one region introduces a single point of failure and does not provide regional fault tolerance.
- C. Correct.
This option is correct because deploying HA VPN tunnels in two regions ensures fault tolerance for regional outages, and dynamic routing with Cloud Router ensures automatic failover.
- D. Incorrect.
This option is incorrect because relying on a single Dedicated Interconnect connection creates a single point of failure and requires manual intervention for failover, which does not meet the requirement for minimal manual intervention.
- E. Correct.
This option is correct because using multiple Partner Interconnect connections across regions ensures regional fault tolerance, and dynamic routing with Cloud Router provides automatic failover.
