CompTIA Network+ (N10-009) — Question 503

A company recently implemented a videoconferencing system that utilizes large amounts of bandwidth. Users start reporting slow internet speeds and an overall decrease in network performance. Which of the following are most likely the causes of the network performance issues? (Choose two.)

Answer options

• A. DNS misconfiguration
• B. Inadequate network security
• C. Malware or a virus
• D. Outdated software
• E. Incorrect QoS settings
• F. Network congestion

Correct answer: E, F

Explanation

The correct answers, E (Incorrect QoS settings) and F (Network congestion), indicate that the Quality of Service settings may not be prioritizing the video conferencing traffic properly, leading to congestion in the network. The other options, such as DNS misconfiguration, inadequate security, malware, and outdated software, are unlikely to directly cause the specific performance issues related to bandwidth usage in this context.
