• Chose B1

  Adding VPN connections may improve bandwidth but does not resolve latency or packet loss issues caused by public internet routing... though not mentioned, we must 'think' beyond the scope of the question and ask 'what is causing the latency'... Answer B.

• Chose B3

  1. Dedicated Interconnect for high performance: Dedicated Interconnect provides a direct physical connection between your on-premises network and Google Cloud. This offers significantly lower latency, higher bandwidth, and greater reliability compared to a VPN. It's ideal for demanding workloads like database replication. 2. Reduced latency and packet loss: By bypassing the public internet, Dedicated Interconnect minimizes latency and packet loss, ensuring consistent and efficient data transfer for your MySQL replication. 3. Enhanced reliability: Dedicated Interconnect provides a more stable and predictable connection compared to a VPN, which can be affected by internet traffic fluctuations. Why D is not correct: Add additional VPN connections and load balance them: This might improve bandwidth slightly but won't address the fundamental latency and packet loss issues inherent with VPNs over the public internet.

• Chose B2

  It's B, Interconnect. D is wrong in this case: While this might help distribute traffic, it won't solve the underlying issue of latency and packet loss caused by the inherent limitations of VPNs.
