CompTIA Network+ (N10-006) — Question 85

A national cable company providing TV, telephone, and Internet service to home users over its IP network, has been tracking a large increase of network bandwidth due to P2P file sharing. Which of the following should the company deploy to ensure excellent TV and telephone service?

Answer options

• A. QoS
• B. Load balancing
• C. High availability
• D. Fiber optics A

Correct answer:

Explanation

Implementing QoS (Quality of Service) is essential for prioritizing network traffic, ensuring that critical services like TV and telephone maintain their quality despite increased bandwidth usage from P2P file sharing. Load balancing distributes traffic but does not specifically address service quality, high availability focuses on system uptime rather than traffic management, and fiber optics improves speed but does not manage bandwidth prioritization.
