Your company is utilizing a multi-cloud architecture with applications running on both OCI and AWS. You have established a Site-to-Site VPN connection between OCI and AWS for secure communication. Over time, you observe that the VPN tunnel becomes unstable and frequently disconnects, particularly during peak hours. You suspect this is due to increased network latency and packet loss. Which action is least likely to improve the stability and reliability of your OCI-AWS Site-to-Site VPN connection in this scenario?
Actually, changing the MTU (C) often makes things worse, not better, unless every hop supports the larger size. If either end or a device in between can't handle it, you'll see more fragmentation and packet loss. Seen similar trick questions on network exams. Pretty sure C is the least likely to help here-unless both sides specifically allow higher MTUs, which isn’t stated.
Yeah, C is the one that won't really help. Increasing MTU without ensuring both sides match just increases the chance for packet fragmentation, especially over VPNs where path MTU discovery isn't always reliable. A and B actually tackle performance and prioritization, D is a bigger investment but improves stability. Unless I'm missing something, C is least likely to solve the issue here. Agree?
