Google Professional Cloud Network Engineer Question 135
Select 3Google Cloud PlatformYour organization needs to ensure high availability and disaster recovery for a hybrid cloud environment. You are tasked with designing a network architecture that connects your on-premises data center to Google Cloud while minimizing downtime and ensuring automatic failover in case of a link failure. Which of the following strategies would best meet these requirements?
- A
Use Cloud VPN with multiple tunnels across different regions and configure dynamic routing with BGP.
- B
Use a single Dedicated Interconnect connection to Google Cloud for high throughput and reliability.
- C
Deploy two Partner Interconnect connections in different metro locations and configure BGP for failover.
- D
Set up a single Cloud VPN tunnel with static routing for simplicity.
- E
Implement multiple Dedicated Interconnect connections in separate edge availability domains and enable dynamic routing with BGP.
Show answer and explanation
Correct answers: A, C, E
Explanation
High availability and disaster recovery connectivity strategies require redundancy, geographic diversity, and automatic failover capabilities. Using multiple Cloud VPN tunnels with BGP, Partner Interconnect connections in different metro locations, or multiple Dedicated Interconnect connections in separate edge availability domains with BGP are all effective approaches. These strategies ensure minimal downtime and seamless failover in case of a network link failure.
- A. Correct.
This option ensures high availability by leveraging multiple Cloud VPN tunnels across regions and dynamic routing with BGP, which allows automatic failover. This is a suitable solution for disaster recovery in a hybrid environment.
- B. Incorrect.
A single Dedicated Interconnect connection does not provide redundancy or automatic failover, making it unsuitable for high availability and disaster recovery scenarios.
- C. Correct.
Using two Partner Interconnect connections in different metro locations ensures geographic redundancy and high availability. Configuring BGP allows for automatic failover in case of a connection failure.
- D. Incorrect.
A single Cloud VPN tunnel with static routing lacks redundancy and does not support automatic failover, making it unsuitable for high availability and disaster recovery.
- E. Correct.
Multiple Dedicated Interconnect connections in separate edge availability domains provide high throughput and redundancy. Dynamic routing with BGP ensures automatic failover, meeting high availability and disaster recovery requirements.
