CompTIA Network+ (N10-008) — Question 143

A network engineer is investigating reports of poor network performance. Upon reviewing a report, the engineer finds that jitter at the office is greater than 10ms on the only WAN connection available. Which of the following would be MOST affected by this statistic?

Answer options

• A. A VoIP sales call with a customer
• B. An in-office video call with a coworker
• C. Routing table from the ISP
• D. Firewall CPU processing time

Correct answer: A

Explanation

Jitter affects the quality of real-time communications, such as VoIP calls, making option A the most impacted. In contrast, an in-office video call (option B) may be less sensitive to jitter due to lower latency requirements. Options C and D are not significantly affected by jitter since they do not rely on real-time transmission of voice or video data.
