Question Image

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

  • A bandwidth 170 to percent 170
  • B bandwidth 170 to reserve 170
  • C bandwidth 170 to priority 170
  • D bandwidth 170 to LLQ 170
Explanation

Cisco IOS implements Low Latency Queueing (LLQ) by applying the priority command under the policy-map class. priority 170 creates a strict-priority queue for the VOICE class with 170 kbps of allocated bandwidth, whereas bandwidth 170 configures nonpriority CBWFQ bandwidth allocation.
