Google Professional Cloud Network Engineer Question 709
Select 3Google Cloud PlatformYour organization is setting up a high-availability hybrid cloud deployment and needs to create Router Appliances (RAs) on Google Cloud to handle dynamic routing between the on-premises network and Google Cloud VPCs. Which of the following steps are required to configure and deploy Router Appliances correctly?
- A
Configure a Cloud Router in the VPC to establish a BGP session with the on-premises router.
- B
Assign a public IP address to the Router Appliance for external connectivity.
- C
Deploy a virtual machine-based Router Appliance from a supported third-party vendor in the appropriate subnet.
- D
Ensure that the Router Appliance is located in the same region as the Cloud Interconnect or VPN Tunnel.
- E
Enable VPC Network Peering to allow the Router Appliance to communicate with other VPCs.
Show answer and explanation
Correct answers: A, C, D
Explanation
To set up Router Appliances (RAs) for a hybrid cloud deployment, you need to configure a Cloud Router for BGP sessions, deploy the Router Appliance as a virtual machine, and ensure it is in the correct region to align with any Cloud Interconnect or VPN Tunnels. Public IP addresses and VPC Network Peering are not necessary in this specific context, making the correct answers 1, 3, and 4.
- A. Correct.
Correct. A Cloud Router is required to establish a BGP session and enable dynamic routing between the on-premises network and Google Cloud.
- B. Incorrect.
Incorrect. Router Appliances do not require a public IP address unless explicitly needed for scenarios like internet routing, which is not mentioned in this case.
- C. Correct.
Correct. Router Appliances are typically deployed as virtual machines using vendor-provided images, and they should be placed in the appropriate subnet.
- D. Correct.
Correct. Router Appliances need to be deployed in the same region as the Cloud Interconnect or VPN Tunnel to ensure proper routing and minimal latency.
- E. Incorrect.
Incorrect. While VPC Network Peering is useful for inter-VPC communication, it is not a requirement for configuring Router Appliances in this hybrid cloud scenario.
