300-420 Question 278
Single answerA company is implementing a network management strategy to ensure critical network monitoring and management traffic is not impacted by high bandwidth usage during peak hours. As the network engineer, you are tasked with prioritizing this traffic. Which of the following approaches would best ensure proper prioritization of network management traffic?
- A
Configure QoS to assign a high-priority queue to network management traffic.
- B
Use VLAN segmentation to isolate network management traffic from user traffic.
- C
Implement rate limiting on all user traffic to ensure sufficient bandwidth for network management.
- D
Deploy a secondary network for network management traffic to avoid interference.
Show answer and explanation
Correct answer: A
Explanation
Prioritizing network management traffic is essential to ensure the proper functioning of monitoring tools and administrative operations. Among the listed options, configuring QoS to assign a high-priority queue to network management traffic is the most effective and practical solution. QoS allows you to prioritize critical traffic dynamically, ensuring it is not delayed during periods of high congestion.
- A. Correct.
Configuring QoS to assign a high-priority queue to network management traffic is the best approach to ensure timely delivery of critical management packets, especially during high network utilization.
- B. Incorrect.
While VLAN segmentation can isolate management traffic from user traffic, it does not inherently provide prioritization. Without QoS, management traffic can still experience delays during congestion.
- C. Incorrect.
Rate limiting all user traffic might help, but it is not a scalable or efficient solution, as it does not dynamically prioritize critical traffic like network management.
- D. Incorrect.
Deploying a secondary network for management traffic could work but is cost-prohibitive and unnecessary when QoS can achieve the same outcome effectively.
