CompTIA Network+ (N10-008) — Question 47

Branch users are experiencing issues with videoconferencing. Which of the following will the company MOST likely configure to improve performance for these applications?

Answer options

• A. Link Aggregation Control Protocol
• B. Dynamic routing
• C. Quality of service
• D. Network load balancer
• E. Static IP addresses

Correct answer: C

Explanation

The correct answer is Quality of service (QoS) because it prioritizes network traffic to ensure that videoconferencing data is transmitted smoothly. The other options, such as Link Aggregation Control Protocol and Network load balancer, do not specifically address the prioritization of traffic types, while dynamic routing and static IP addresses are not focused on performance enhancement for specific applications.
