Google Professional-Cloud-Network-Engineer Question Answer

After a network change window one of your company’s applications stops working. The application uses an on-premises database server that no longer receives any traffic from the application. The database server IP address is 10.2.1.25. You examine the change request, and the only change is that 3 additional VPC subnets were created. The new VPC subnets created are 10.1.0.0/16, 10.2.0.0/16, and 10.3.1.0/24/ The on-premises router is advertising 10.0.0.0/8.

What is the most likely cause of this problem?

The less specific VPC subnet route is taking priority.

The more specific VPC subnet route is taking priority.

The on-premises router is not advertising a route for the database server.

A cloud firewall rule that blocks traffic to the on-premises database server was created during the change.
