Google Professional Cloud Network Engineer Question 133
Select 2Google Cloud PlatformYour company is deploying a critical application hosted in Google Cloud that requires high availability and disaster recovery. The application is designed to handle traffic from multiple regions. You need to establish a connectivity strategy between your on-premises data center and Google Cloud that ensures minimal downtime during a regional failure while maintaining low latency. Which combination of strategies should you choose?
- A
Set up Dedicated Interconnect with redundant connections in two separate Google Cloud regions.
- B
Use a single VPN tunnel connecting your on-premises data center to the nearest Google Cloud region.
- C
Leverage Partner Interconnect with dual connections in a single Google Cloud region.
- D
Implement Cloud VPN with multiple tunnels to different Google Cloud regions.
- E
Configure Dedicated Interconnect with multiple circuits in one Google Cloud region for higher bandwidth.
Show answer and explanation
Correct answers: A, D
Explanation
To ensure high availability and disaster recovery, you need to avoid single points of failure at both the network and regional levels. Dedicated Interconnect offers high-speed, low-latency connectivity, and deploying it in multiple regions ensures resilience in case of a regional failure. Cloud VPN with multiple tunnels to different regions provides a cost-effective alternative for redundancy and disaster recovery. Combining these strategies ensures minimal downtime and low latency for the application.
- A. Correct.
Setting up Dedicated Interconnect with redundant connections in two separate regions ensures high availability and disaster recovery by avoiding a single point of failure at the regional level.
- B. Incorrect.
Using a single VPN tunnel provides basic connectivity but lacks redundancy and would result in downtime if the regional connection fails.
- C. Incorrect.
Using Partner Interconnect with dual connections in a single region provides some redundancy but cannot protect against a regional failure, which is required for disaster recovery.
- D. Correct.
Implementing Cloud VPN with multiple tunnels to different regions provides redundancy and ensures connectivity during a regional failure, making it a suitable choice for disaster recovery.
- E. Incorrect.
Configuring Dedicated Interconnect with multiple circuits in one region increases bandwidth but does not address high availability or disaster recovery if the region becomes unavailable.
