Free Updated Cisco 300-610 Actual Exam Questions - Question 1 Discussion
An engineer is configuring a QoS policy with these requirements
Match-all AF11 traffic and set it to a DSCP value of 14.
The committed rate must be 10 Mbps with a committed burst rate of 1000 ms
Drop any AF11 traffic that violates these settings.
Any traffic other than af11 must have a DSCP value of 0
The given class-map configuration already exists. Which solution must the engineer use to meet the
requirements?
A)
B)
C)
D)
A vs D, only A explicitly sets the committed burst to 1000 ms as required.
Maybe A is better because it clearly marks AF11 traffic with DSCP 14 and sets policing, while also handling other traffic separately to reset DSCP to 0.
C/D? Option C misses setting DSCP 0 for other traffic, so it doesn’t fully meet the requirements. Option D explicitly sets DSCP 0 for non-AF11, which fits the question better.
Maybe D makes more sense here. It uses a policy map with a class for AF11 traffic that sets DSCP to 14 and applies policing at 10 Mbps with a 1000 ms burst, dropping excess traffic, which matches the requirements well. Plus, it has a default class that sets DSCP to 0 for all other traffic, covering the non-AF11 part explicitly. The others either miss setting DSCP 0 on non-AF11 or don’t handle policing exactly as specified. So D seems to tick all the boxes given in the question.
B looks right, matches AF11 and sets DSCP 14 properly.
