When evaluating QoS, you should expect it to:

• A. Control bandwidth.
• B. Provide malware scanning.
• C. Maintain server uptime automatically.
• D. Provide content filtering.

Answer: (A)

Quality of Service focuses on managing how network bandwidth is allocated and prioritizing traffic so critical applications receive sufficient resources, even during congestion. When evaluating QoS, you should expect mechanisms like traffic shaping, policing, and queuing that control and prioritize bandwidth for important traffic. It does not perform malware scanning, automatic server uptime maintenance, or content filtering—that's the realm of security, reliability, and access-control features, not QoS. So the main outcome with QoS is controlling bandwidth to ensure predictable performance.
