300-445 Question 252
Select 2An enterprise network experiences periodic congestion during business hours, leading to packet drops and delays in critical applications. After analyzing historical traffic data, you notice that video conferencing traffic spikes during specific time windows, consuming a large portion of the available bandwidth. What optimization recommendations should you propose to address this issue while ensuring critical applications maintain performance?
- A
Implement Quality of Service (QoS) policies to prioritize critical application traffic over video conferencing traffic.
- B
Increase the bandwidth of the network links to accommodate the video conferencing traffic spikes.
- C
Adjust the network topology to introduce additional redundant paths for load balancing during congestion.
- D
Schedule video conferencing sessions during non-peak hours to reduce congestion.
- E
Deploy traffic shaping to limit the bandwidth used by video conferencing traffic.
Show answer and explanation
Correct answers: A, E
Explanation
This scenario requires balancing bandwidth usage and ensuring critical applications are not impacted by video conferencing traffic spikes. Implementing QoS prioritizes critical traffic during congestion, while traffic shaping restricts video conferencing traffic to manageable levels. Together, these solutions effectively optimize network capacity without requiring costly upgrades or unrealistic scheduling changes.
- A. Correct.
Implementing QoS ensures that critical applications, such as business-critical systems, maintain priority during congestion. This approach directly addresses the issue without requiring additional resources.
- B. Incorrect.
Increasing bandwidth may temporarily alleviate the problem, but this is a costly solution and does not address the underlying issue of prioritizing critical traffic during congestion.
- C. Incorrect.
Changing the network topology to add redundant paths may improve overall network resilience but is not a direct solution to prioritizing specific traffic or managing bandwidth spikes.
- D. Incorrect.
Scheduling video conferencing during non-peak hours may help reduce congestion but is impractical for most enterprises where such scheduling flexibility is limited.
- E. Correct.
Traffic shaping helps control the bandwidth usage of video conferencing traffic, ensuring it does not consume excessive resources and allowing critical applications to perform without disruption.
