Google Professional Cloud Network Engineer Question 705
Select 2Google Cloud PlatformYou are designing a network topology in Google Cloud and need to deploy Router Appliances (RAs) to handle dynamic routing between your on-premises network and multiple VPCs in Google Cloud. Which of the following steps are necessary to correctly configure and deploy the Router Appliances?
- A
Create a Cloud Router for each VPC that will connect to the Router Appliance.
- B
Deploy the Router Appliance as a Compute Engine instance in a shared VPC subnet.
- C
Configure BGP sessions between the Router Appliance and the on-premises router.
- D
Enable Private Google Access on the subnet where the Router Appliance is deployed.
- E
Set up IAM permissions to allow the Router Appliance to manage routes in the VPC.
Show answer and explanation
Correct answers: A, C
Explanation
To deploy Router Appliances in Google Cloud for dynamic routing, you must create a Cloud Router for each VPC that will exchange routes dynamically with the Router Appliance. Additionally, BGP sessions must be configured between the Router Appliance and the on-premises router to enable dynamic routing. Other steps, such as enabling Private Google Access or setting up specific IAM permissions for route management, are not directly related to the deployment and configuration of Router Appliances.
- A. Correct.
Correct: A Cloud Router is required for each VPC to enable dynamic route exchange via BGP with the Router Appliance.
- B. Incorrect.
Incorrect: Router Appliances are typically deployed in a specific VPC, not necessarily in a shared VPC subnet unless explicitly required by the architecture.
- C. Correct.
Correct: BGP is essential for dynamic route exchange between the Router Appliance and the on-premises router.
- D. Incorrect.
Incorrect: Enabling Private Google Access is not mandatory for deploying Router Appliances. It is used for accessing Google APIs and services privately.
- E. Incorrect.
Incorrect: IAM permissions are not directly set up for Router Appliances to manage routes. Route management is handled by Cloud Router and attached BGP sessions.
