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?

A. B. C. D. E.B.
In this scenario, the company is experiencing latency issues and packet loss while replicating their production MySQL database from their private data center to their GCP project using a Google Cloud VPN connection. This issue is disrupting the replication process, and the company needs to find a solution to overcome it. The possible solutions are:
A. Configure their replication to use UDP: UDP (User Datagram Protocol) is a connectionless protocol that does not provide reliability or error correction. Using UDP can reduce latency, but it can also result in data loss, which can be catastrophic for a production database. Therefore, using UDP is not a recommended solution in this scenario.
B. Configure a Google Cloud Dedicated Interconnect: A Dedicated Interconnect provides a direct physical connection between the company's private data center and the GCP project, bypassing the public internet. This solution can reduce latency and eliminate packet loss, providing a more reliable and secure connection. However, Dedicated Interconnect can be costly and may take some time to set up.
C. Restore their database daily using Google Cloud SQL: Cloud SQL is a fully managed database service that can replicate data to a secondary location for disaster recovery purposes. By using Cloud SQL, the company can avoid the complexity of managing their own database replication while also benefiting from automatic failover and high availability. However, restoring the database daily may not meet the company's recovery time objective (RTO) if a disaster occurs.
D. Add additional VPN connections and load balance them: Adding more VPN connections and load balancing them can distribute the traffic and provide redundancy, which can improve availability and reduce latency. However, this solution may not be effective in eliminating packet loss, and it can be difficult to manage multiple VPN connections.
E. Send the replicated transaction to Google Cloud Pub/Sub: Cloud Pub/Sub is a messaging service that can decouple the production and replication systems, allowing them to operate independently. By sending the replicated transaction to Pub/Sub, the company can ensure that the data is transmitted reliably without being affected by latency or packet loss. However, this solution may require significant changes to the company's existing replication architecture.
In conclusion, the best solution for the company depends on their specific requirements, budget, and tolerance for risk. However, in general, using a Dedicated Interconnect or Cloud SQL can provide a more reliable and secure solution than using VPN connections or UDP. Sending the replicated transaction to Pub/Sub can also be a viable solution if the company is willing to make significant changes to their existing replication architecture.
