300-420 Question 276
Select 3A large enterprise network is experiencing delays in network management traffic, resulting in slower response times for configuration changes and monitoring updates. As the network designer, how should you prioritize network management traffic to ensure optimal performance and reliability?
- A
Configure a dedicated QoS policy to assign higher priority to network management protocols such as SNMP and Syslog.
- B
Use separate VLANs for network management traffic to isolate it from user data traffic.
- C
Enable rate limiting on network management traffic to reduce its impact on user data traffic.
- D
Mark network management traffic with a high DSCP value, such as CS6, to ensure it receives priority treatment.
- E
Disable unused network management protocols to reduce unnecessary traffic on the network.
Show answer and explanation
Correct answers: A, B, D
Explanation
To ensure optimal performance of network management traffic, it is essential to prioritize it using techniques like QoS policies and DSCP markings and to isolate it from user traffic using VLANs. These methods collectively improve the reliability and responsiveness of network management operations while minimizing interference from other traffic types.
- A. Correct.
Correct: Configuring a dedicated QoS policy ensures that network management traffic receives prioritized treatment over other traffic types, reducing delays and improving reliability.
- B. Correct.
Correct: Isolating network management traffic into separate VLANs prevents interference from user data traffic and enhances security and performance.
- C. Incorrect.
Incorrect: While rate limiting can prevent network management traffic from overwhelming the network, it is not a prioritization technique and could further delay important management functions.
- D. Correct.
Correct: Marking traffic with a high DSCP value ensures that management traffic is recognized and prioritized by QoS mechanisms throughout the network.
- E. Incorrect.
Incorrect: Disabling unused network management protocols can reduce unnecessary traffic but does not directly affect prioritization of active management traffic.
