Google Cloud Professional Cloud Network Engineer — Question 164

You are designing a new network infrastructure for your customer in Google Cloud. Your customer requires a connection between two Google Cloud VPCs that must include a VPN tunnel. You want to follow Google-recommended practices while ensuring maximum availability of the connection. Which VPN configuration should you choose?

Answer options

• A. Policy-based VPN using Classic VPN between the two Google Cloud VPCs
• B. Border Gateway Protocol (BGP)-based VPN using Classic VPN between the two Google Cloud VPCs
• C. Route-based VPN using Classic VPN between the two Google Cloud VPCs
• D. Border Gateway Protocol (BGP)-based VPN using HA VPN between the two Google Cloud VPCs

Correct answer: D

Explanation

The correct answer is D because using BGP with HA VPN provides better redundancy and failover capabilities, which aligns with Google's recommendations for high availability. Options A, B, and C do not offer the same level of availability and resilience as option D, making them less suitable for the customer's requirements.
