300-445 Question 249
Select 4An enterprise network is experiencing frequent congestion and packet loss during peak hours, impacting critical applications. Upon analyzing the network data, you discover that the issue is concentrated within a specific branch office connected through a hub-and-spoke topology. The analysis also shows that voice traffic and video conferencing are being affected the most. Which of the following recommendations would optimize network capacity and address these issues?
- A
Implement QoS policies to prioritize voice and video traffic over less critical traffic.
- B
Reconfigure the topology to a full-mesh architecture to reduce traffic bottlenecks at the hub.
- C
Increase the bandwidth of the branch office's WAN link to handle peak-hour traffic.
- D
Implement traffic shaping on the branch office network to limit non-critical traffic.
- E
Relocate critical applications to the branch office to reduce WAN dependency.
Show answer and explanation
Correct answers: A, B, C, D
Explanation
The network issues can be mitigated by a combination of QoS policies, topology changes, bandwidth upgrades, and traffic shaping. These measures optimize network capacity, prioritize critical traffic, and reduce congestion. However, relocating applications is not an effective solution in this context as it does not address the root cause of the problem and may introduce new challenges.
- A. Correct.
Correct: Implementing QoS ensures that voice and video traffic receive higher priority, reducing the impact of congestion on these critical services.
- B. Correct.
Correct: Switching to a full-mesh topology can alleviate bottlenecks at the hub by allowing more direct communication paths, improving overall network performance.
- C. Correct.
Correct: Increasing the WAN link bandwidth provides additional capacity to accommodate higher traffic volumes during peak hours, reducing the chances of congestion.
- D. Correct.
Correct: Traffic shaping controls the flow of non-critical traffic, preventing it from overwhelming the network and ensuring critical traffic has sufficient bandwidth.
- E. Incorrect.
Incorrect: Relocating applications to the branch office may not be practical and does not directly address the underlying network congestion or capacity issues.
