Google Cloud Professional Cloud Architect — Question 60

As part of implementing their disaster recovery plan, your company is trying to replicate their production MySQL database from their private data center to their
GCP project using a Google Cloud VPN connection. They are experiencing latency issues and a small amount of packet loss that is disrupting the replication.
What should they do?

Answer options

• A. Configure their replication to use UDP.
• B. Configure a Google Cloud Dedicated Interconnect.
• C. Restore their database daily using Google Cloud SQL.
• D. Add additional VPN connections and load balance them.
• E. Send the replicated transaction to Google Cloud Pub/Sub.

Correct answer: B

Explanation

The correct answer is B because a Google Cloud Dedicated Interconnect provides a direct physical connection to Google’s network, reducing latency and mitigating packet loss issues. The other options do not address the underlying network performance problems effectively; for instance, using UDP (A) may worsen reliability issues, while daily restores (C) do not facilitate real-time replication. Adding VPN connections (D) may not resolve the latency issue, and sending transactions to Pub/Sub (E) is not a suitable approach for database replication.
