7. Question 137 · 450 in bank

   Refer to the exhibit.

   

   An engineer must modify the existing QoS policy-map statement to implement LLQ for voice traffic. Which change must the engineer make in the configuration?

   • Abandwidth 170 to percent 170
   • Bbandwidth 170 to reserve 170
   • Cbandwidth 170 to priority 170
   • Dbandwidth 170 to LLQ 170

   Show answer

   Answer: C

   Explanation

   From Cisco book : LLQ provides strict priority queueing for CBWFQ, reducing jitter in voice conversations in other queues are dequeued. Configured by the priority command, LLQ enables use of a single, strict priority queue within CBWFQ at the class level, allowing you to direct traffic belonging to a class to the CBWFQ strict priority queue.

8. Question 138 · 450 in bank

   Which characteristic of distributed class-based weighted fair queueing addresses jitter prevention?

   • AIt provides additional granularity by allowing a user to create classes.
   • BIt uses a priority queue for voice traffic to avoid jitter.
   • CIt minimizes jitter by implementing a priority queue for voice traffic.
   • DIt provides additional granularity by allowing a user to define custom classes.
