Google Professional Cloud Network Engineer Question 652
Select 3Google Cloud PlatformYou are tasked with configuring a highly available hybrid connectivity solution between your on-premises network and Google Cloud. The design requires using HA VPN over a Cloud Interconnect connection to ensure redundancy and low latency. Which of the following steps are required to properly configure this setup?
- A
Create two HA VPN gateways in different Google Cloud regions.
- B
Attach two VLAN attachments to the Cloud Interconnect, one for each HA VPN tunnel.
- C
Configure dynamic routing with Cloud Router for each VLAN attachment.
- D
Create exactly one tunnel per HA VPN gateway for redundancy.
- E
Ensure that the on-premises VPN gateway supports BGP for dynamic route exchange.
Show answer and explanation
Correct answers: B, C, E
Explanation
To configure HA VPN over Cloud Interconnect, you must establish redundancy at multiple levels. This includes using two VLAN attachments for the Cloud Interconnect, configuring dynamic routing with Cloud Router, and ensuring the on-premises VPN gateway supports BGP for dynamic route exchange. Creating two tunnels per HA VPN gateway is necessary for redundancy, but the question does not ask for tunnel configuration specifics.
- A. Incorrect.
Incorrect: HA VPN gateways in different regions are not required. A single HA VPN gateway with two interfaces in the same region is sufficient for redundancy.
- B. Correct.
Correct: Two VLAN attachments are required to connect the Cloud Interconnect to the HA VPN tunnels, ensuring redundancy.
- C. Correct.
Correct: Configuring dynamic routing with Cloud Router for each VLAN attachment is necessary to exchange routes between the on-premises network and Google Cloud.
- D. Incorrect.
Incorrect: Each HA VPN gateway must have two tunnels for redundancy, not just one. This ensures high availability.
- E. Correct.
Correct: The on-premises VPN gateway must support BGP to enable dynamic routing and ensure proper route exchange with Cloud Router.
