What should you do?

A. Set up a high availability VPN between the app-dev and db-dev VPCs. Connect the application directly to AlloyDB.
B. Connect by using the private IP address of the AlloyDB cluster directly from the application.

Selected Answer: B

Private Service Access (PSA) establishes a private connection between your VPC and the Google-managed service network where AlloyDB resides. This allows resources in your VPC (such as GKE pods) to communicate with AlloyDB using its private IP, without needing public IPs or VPNs

To be fair, i think this question is incorrectly described here - You have 1st VPC with GKE and you have Managed Database visible in 2nd VPC with its private IP because of PSA. As you mentioned these two VPCs are not connected at all and communication won't be possible between them. I think i have to admit, option C might be the answer here.
