CompTIA Network+ (N10-008) — Question 753

A network technician is troubleshooting VoIP calls that have jumbled and distorted audio. The network technician analyzes the voice VLAN traffic and determines packets on the voice VLAN are being received out of order. Which of the following network metrics are causing the VoIP issues?

Answer options

• A. Jitter
• B. Bandwidth
• C. Latency
• D. Delay

Correct answer: A

Explanation

Jitter refers to the variability in packet arrival times, which can lead to packets being received out of order, causing audio distortion in VoIP calls. While bandwidth, latency, and delay are important metrics for network performance, they do not specifically address the issue of packets arriving in the wrong sequence.
