300-420 Question 277
Select 2An enterprise network is experiencing intermittent slowdowns in device monitoring and log collection across its campus network. As the network administrator, you have been tasked with prioritizing network management traffic to ensure reliable monitoring and troubleshooting. Which of the following actions should you take to achieve this?
- A
Configure a dedicated QoS class for network management traffic with a higher priority than regular data traffic.
- B
Apply rate limiting to network management traffic to prevent it from consuming excessive bandwidth.
- C
Mark network management traffic with a specific DSCP value such as CS6 or AF41 for prioritization.
- D
Route network management traffic over a separate physical network to isolate it from production traffic.
- E
Set up GRE tunnels to encapsulate and prioritize network management traffic.
Show answer and explanation
Correct answers: A, C
Explanation
Prioritizing network management traffic is critical to ensure reliable network monitoring and troubleshooting. Configuring QoS to assign a higher priority to this traffic and marking it with specific DSCP values are effective methods. These approaches ensure that network management traffic is less likely to be dropped during congestion, maintaining the integrity of monitoring and management processes.
- A. Correct.
Correct: Configuring a dedicated QoS class ensures that network management traffic has a higher priority, preventing it from being dropped during congestion.
- B. Incorrect.
Incorrect: While rate limiting can control bandwidth usage, it does not prioritize network management traffic. This could further degrade performance during congestion.
- C. Correct.
Correct: Marking traffic with DSCP values like CS6 or AF41 helps devices and routers recognize and prioritize network management traffic across the network.
- D. Incorrect.
Incorrect: While isolating network management traffic on a separate physical network could be beneficial, it is not always feasible in enterprise environments and is not a prioritization mechanism.
- E. Incorrect.
Incorrect: GRE tunnels encapsulate traffic but do not inherently provide prioritization. Additional configurations (e.g., QoS) would still be required for prioritization.
