CompTIA Network+ (N10-008) — Question 101

A user is having difficulty with video conferencing and is looking for assistance. Which of the following would BEST improve performance?

Answer options

• A. Packet shaping
• B. Quality of service
• C. Port mirroring
• D. Load balancing

Correct answer: B

Explanation

Quality of service (QoS) prioritizes network traffic, ensuring that video conferencing data gets the bandwidth it needs to function effectively. Packet shaping, port mirroring, and load balancing do not specifically target the enhancement of video conferencing performance as directly as QoS does.
