Several users in an organization report connectivity issues and lag during a video meeting. The network administrator performs a tcpdump and observes increased retransmissions for other non-video applications on the network. Which of the following symptoms describes the users' reported issues?
Suggested Answer: B Vote an answer
Packet loss occurs when network packets fail to reach their destination, leading to disruptions in connectivity and performance issues. In this scenario:
* Users report connectivity issues and lag during video meetings.
* The administrator detects increased retransmissions in tcpdump, which is a strong indicator of lost packets that must be resent.
* Video meetings are particularly sensitive to packet loss, leading to buffering, frozen screens, and dropped calls.
Latency (Option A) refers to delayed data transmission but does not necessarily cause retransmissions.
Bottlenecking (Option C) happens when a network component (e.g., router, switch) cannot handle the traffic load, but packet retransmissions are more directly related to packet loss.
Jitter (Option D) affects the consistency of packet arrival times, but the symptoms described here are more aligned with packet loss rather than timing variations.
