Google Professional Cloud Network Engineer Question 707
Select 3Google Cloud PlatformYour organization is deploying a hybrid cloud architecture and requires a highly available router appliance (RA) to facilitate communication between your on-premises environment and Google Cloud. You need to ensure redundancy and scalability for your router appliance deployment. Which of the following steps should you take to achieve this?
- A
Deploy two router appliances in separate regions and configure active-active failover.
- B
Deploy two router appliances in the same region and configure them with active-passive failover.
- C
Use Google Cloud Load Balancer to route traffic across multiple router appliances.
- D
Ensure that each router appliance is connected to a unique Cloud Router in the same VPC.
- E
Configure Border Gateway Protocol (BGP) sessions between your on-premises routers and each Cloud Router.
Show answer and explanation
Correct answers: B, D, E
Explanation
To create a highly available router appliance (RA) deployment in Google Cloud, you should deploy multiple RAs in the same region using active-passive failover to ensure redundancy. Each RA must connect to a unique Cloud Router in the same VPC to avoid single points of failure. Additionally, configuring BGP sessions ensures robust and dynamic routing for seamless failover and scalability. Deploying RAs in separate regions is not necessary for high availability within a single region, and Google Cloud Load Balancer is not suitable for routing traffic to RAs.
- A. Incorrect.
Deploying router appliances in separate regions can provide disaster recovery, but it does not directly improve high availability within a single region. Active-active failover also requires additional configuration to handle split-brain scenarios, which can complicate the setup.
- B. Correct.
Deploying two router appliances in the same region with active-passive failover ensures redundancy and high availability. If one appliance fails, the other takes over seamlessly.
- C. Incorrect.
Google Cloud Load Balancer is not designed to manage traffic routing for router appliances. It is primarily used for balancing traffic to backend services.
- D. Correct.
Ensuring that each router appliance is connected to a unique Cloud Router in the same VPC allows redundancy and prevents a single point of failure in the routing setup.
- E. Correct.
Configuring BGP sessions between your on-premises routers and each Cloud Router ensures dynamic routing and the ability to handle failover scenarios effectively.
