CompTIA Network+ (N10-008) — Question 666

When a user makes a VoIP phone call and finishes speaking, the user experiences a delay in hearing a response. Which of the following should the network engineer check?

Answer options

• A. Jitter
• B. Latency
• C. Bandwidth
• D. CRC errors

Correct answer: B

Explanation

The correct answer is B, as latency refers to the time it takes for data to travel from the sender to the receiver. High latency can cause delays in communication, making it difficult for users to hear responses promptly. Jitter affects the variability of packet arrival times, bandwidth relates to data transfer capacity, and CRC errors indicate data corruption, but they do not directly address the delay issue in hearing responses.
