300-445 Question 253
Select 3A global enterprise organization has observed high latency and packet drops in its primary data center during peak hours. Upon analyzing traffic patterns, it is determined that certain business-critical applications like video conferencing and VoIP are being affected. As part of network capacity planning, which actions should the organization implement to optimize the network's performance?
- A
Reconfigure Quality of Service (QoS) policies to prioritize video conferencing and VoIP traffic over less critical traffic.
- B
Increase the bandwidth of the primary data center's uplink to handle peak traffic loads.
- C
Implement traffic shaping to limit the bandwidth usage of non-critical applications during peak hours.
- D
Deploy additional load balancers to distribute traffic across multiple network paths.
- E
Migrate business-critical applications, such as VoIP, to a separate dedicated network segment.
Show answer and explanation
Correct answers: A, B, C
Explanation
To optimize network capacity planning in this scenario, a combination of QoS prioritization, increasing bandwidth, and implementing traffic shaping will ensure that business-critical applications like VoIP and video conferencing are not impacted by congestion and that resources are allocated effectively during peak hours. Load balancers and network segmentation are not directly relevant to resolving the described issues of latency and packet drops.
- A. Correct.
Reconfiguring QoS policies to prioritize video conferencing and VoIP ensures that latency-sensitive applications receive the required bandwidth and lower priority traffic is deprioritized. This is a key optimization strategy.
- B. Correct.
Increasing the bandwidth of the data center's uplink is a direct capacity planning solution to handle higher traffic volumes and reduce congestion.
- C. Correct.
Traffic shaping allows for better control over bandwidth usage by non-critical applications, ensuring that critical applications have sufficient resources during peak hours.
- D. Incorrect.
While deploying load balancers can improve traffic distribution, this does not address the latency and packet drops caused by insufficient bandwidth or improper prioritization in this scenario.
- E. Incorrect.
Migrating business-critical applications to a dedicated network segment is not necessary in this case, as the issues can be resolved through QoS configuration and bandwidth optimization.
