Refer to the exhibit. You are trying to police down to 100 Mb/s. While testing, you notice that you rarely exceed 70-80 Mb/s. What do you need to change in your MQC configuration to allow for 100 Mb/s speeds?
A. Change the CIR value from 100 Mb/s to 200 Mb/s.
B. Change the Bc value to allow for a large enough burst.
C. Change the QoS queue from default to priority.
D. Change the exceed-action to transmit.
Answer: B
Explanation:
Burst size–Also called the Committed Burst (Bc) size, it specifies in bits (or bytes) per burst how much traffic can be sent within a given unit of time to not create scheduling concerns. (For a shaper, such as GTS, it specifies bits per burst; for a policer, such as CAR, it specifies bytes per burst.)
