Question 1 of 30

In a network troubleshooting scenario, you are tasked with analyzing packet captures from a data center environment where both Wireshark and tcpdump have been utilized. You notice that a significant number of TCP packets are being retransmitted. Given that the capture shows a high number of SYN packets followed by SYN-ACK packets, but no corresponding ACK packets, what could be the most likely cause of this issue, and how would you approach diagnosing it using the tools at your disposal?

A firewall is blocking the ACK packets from reaching the sender.

The sender's TCP stack is misconfigured, causing it to drop ACK packets.

The network interface card (NIC) is malfunctioning, leading to packet loss.

The server is overwhelmed and unable to process incoming connections.
