Enterprise Module 9-12 review

What is one of the effects of congestion on a network?

• A) Increased packet processing speed
• B) Reduced packet loss
• C) Delayed packet transmission
• D) Improved queuing mechanisms

What can happen to packets in a congested network?

• A) They are processed in the order they were received.
• B) They are prioritized based on their size.
• C) They are dropped by network devices.
• D) They are transmitted immediately without delay.

What is the purpose of classifying data into multiple queues in QoS?

• A) To prioritize real-time and interactive traffic over other types of data.
• B) To increase the overall network bandwidth.
• C) To reduce the queuing delay for all types of data.
• D) To eliminate delay and jitter in the network.

What is one of the main characteristics of video traffic?

• A) Low sensitivity to drops and delays
