CompTIA Network+ (N10-009) — Question 221

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?

Answer options

• A. Latency
• B. Packet loss
• C. Bottlenecking
• D. Jitter

Correct answer: B

Explanation

The correct answer is B, Packet loss, as it refers to the failure of data packets to reach their destination, which can cause connectivity issues and lag. Latency (A) refers to delays in transmission time, while Bottlenecking (C) describes a point of congestion, and Jitter (D) refers to variability in packet arrival times; none of these directly explain the retransmissions observed.
