You are asked to implement CoS on an EX Series switch. You attempt to configure the
priority for the voice and data queue schedulers to medium-high and medium-low priority,
respectively. However, you notice that the only parameters available for the priority is strict
high and low. Why are strict high and low the only available parameters for configuration?

A.
The loss priority for the queues must first be set to medium-low and medium-high,
respectively.

B.
The switch only supports the strict high and low queue priorities.

C.
The shared buffer feature must be configured prior to configuring scheduler priority.

D.
The scheduler must be applied to an interface prior to configuring scheduler priority.
