R1 assigns incoming voice traffic to the ef forwarding class. All other traffic is assigned to the best-effort forwarding class. You have configured a CoS re-write rule on R1 to include the correct CoS bit values in packets sent towards R2. You want R2 to classify traffic using the CoS markings created by R1.
Which two configuration steps are necessary to accomplish this task? (Choose two.)
To accomplish the task where R2 needs to classify traffic using the CoS markings created by R1, the following steps are necessary: Firstly, assign the behavior aggregate classifier to the ge-0/0/1.0 interface on R2. This ensures that incoming traffic on R2 is classified according to the CoS markings set by R1. Secondly, configure a behavior aggregate classifier on R2, which specifies how traffic should be categorized based on the CoS bits in the packets. The re-write of the CoS bits has already been done by R1, so R2 only needs to classify the traffic using these markings.
A,D. Rewrite is already done on R1.
A,D Rewrite rule should be configured on egress
A,D look more reasonable.
I agree with Sheet and vasiliy19.
A,D makes most sense
A,D are correct. We must configure BA Classifier and then apply it to the interface to take affect.
A,D re-write is performed by R1. R2 only needs to classify the traffic based on that, and that is done using BA classifier
It considering that R1 did your job of classifying and rewriting the traffic on a direction R2 needs to do the same on the inverse direction, because of that the correct answers are A and B.
