Google Professional Cloud Network Engineer Question 131
Select 4Google Cloud PlatformYour organization is designing a hybrid network to connect two on-premises data centers to Google Cloud. The connectivity must be highly available and resilient to potential failures. Which combination of strategies should you implement to achieve this goal?
- A
Set up redundant Cloud VPN tunnels from each data center to Google Cloud using different regions and zones.
- B
Use Dedicated Interconnect with redundant circuits and configure them in different edge availability domains.
- C
Set up a single Cloud VPN tunnel and use a failover policy to redirect traffic to it in case of a failure.
- D
Implement Partner Interconnect with multiple VLAN attachments spread across diverse Google edge locations.
- E
Use a hybrid approach combining Dedicated Interconnect and Cloud VPN for backup.
Show answer and explanation
Correct answers: A, B, D, E
Explanation
To achieve high availability and disaster recovery for hybrid connectivity, it is essential to implement redundancy at every layer. Using redundant Cloud VPN tunnels, Dedicated Interconnect with redundant circuits, and Partner Interconnect with diverse VLAN attachments ensures that there are no single points of failure. Additionally, combining Dedicated Interconnect for primary connectivity and Cloud VPN as a backup provides a hybrid strategy that enhances resiliency.
- A. Correct.
This is correct. Redundant Cloud VPN tunnels across different regions and zones help ensure high availability and disaster recovery by mitigating the risks of individual region or zone failures.
- B. Correct.
This is correct. Dedicated Interconnect with redundant circuits in different edge availability domains provides high availability and resilience for critical workloads.
- C. Incorrect.
This is incorrect. A single Cloud VPN tunnel is a single point of failure, which does not meet high-availability requirements.
- D. Correct.
This is correct. Partner Interconnect with multiple VLAN attachments across diverse edge locations ensures high availability and disaster recovery by avoiding reliance on a single connection or location.
- E. Correct.
This is correct. Combining Dedicated Interconnect for primary connectivity and Cloud VPN for backup provides a hybrid and resilient connectivity strategy for disaster recovery.
