Implementing and Operating Cisco Service Provider Network Core Technologies (SPCOR) — Question 95

A network engineer is implementing a QoS policy for outbound management traffic classification and marking on a CPE device with these requirements:
✑ Management protocols must be marked with DSCP AF class 2 with low drop probability.
✑ Monitoring protocols must be marked with DSCP AF class 1 with low drop probability.
✑ All remaining traffic must be marked with a DSCP value of 0.
Which configuration must the engineer implement to satisfy the requirements?

Answer options

• A. policy-map cpe-mgmt-policy class management set ip dscp af21 class monitoring set ip dscp af11 class class-default set ip dscp default end
• B. policy-map cpe-mgmt-policy class management set ip dscp af21 class monitoring set ip dscp af11 class class-default set ip dscp af0 end
• C. policy-map cpe-mgmt-policy class management set ip dscp af23 class monitoring set ip dscp af13 class class-default set ip dscp default end
• D. policy-map cpe-mgmt-policy class management set ip dscp af23 class monitoring set ip dscp af13 class class-default set ip dscp af0 end

Correct answer: A

Explanation

The correct answer, A, correctly marks management protocols with DSCP AF class 2 and monitoring protocols with DSCP AF class 1, ensuring low drop probability as specified. Options B, C, and D do not meet the requirement for management and monitoring protocol markings, either using incorrect DSCP values or failing to mark remaining traffic with a DSCP value of 0.
