QUESTION 63

What is the function of class-based marking?

 

A.      Marking packets is based only on CoS value, IP precedence value or DSCP value allows Layer 3 frames to be identified and distinguished from other packets.

B.      Marking frames based only on CoS value or IP precedence value allows Layer 2 frames to be identified and distinguished from other frames.

C.      Marking frames or packets sets information in the Layer 2 and Layer 3 headers of a packet so that the frame or packet can be identified and distinguished from other frames or packets in the same traffic flow.

D.      Marking frames only sets information in the Layer 2 headers of a frame so that the frame can be identified and distinguished from other packets or frames.

E.       Marking allows network devices to classify a packet or frame, based on a specific traffic descriptor.

 

Answer: E

QUESTION 65

Which statement best describes dial peers in a voice gateway. (Choose two.)

 

A.      Dial peers are call legs that are used to identify call source and destination endpoints and to define the characteristics that are applied to each call leg in the call connection.

B.      Dial peers are configured with call legs that are essential to implementing dial plans and providing voice services over an IP packet network.

C.      A dial peer is a physical addressable endpoint in a voice gateway.

D.      Dial peers create physical connections called call legs to complete an end-to-end call.

 

Answer: A,C

 

 

QUESTION 66

Which QoS mechanism for VoIP works with weighted fair queuing (WFQ) and class-based weighted fair queuing (CBWFQ)?

 

A.      Header compression

B.      FRF.12

C.      IP RTP Priority and Frame Relay IP RTP Priority

D.      Multilink PPP

E.       RSVP

 

Answer: C

 

 

QUESTION 67

How does LLQ ensure that voice traffic is always expedited?

 

A.      LLQ adds WRED to CBWFQ. This allows delay-sensitive data such as voice to be dequeued and sent first.

B.      LLQ uses CBWFQ to prioritize voice traffic and by dequeuing the voice packets so they can be handled first.

C.      The strict priority queue has a higher weight than the queues in CBWFQ. This weight allows the delay-sensitive data such as voice to be dequeued and sent first.

D.      The LLQ strict priority queue allows delay-sensitive data such as voice to be dequeued and sent first (before packets in other queues are dequeued), giving delay-sensitive data preferential treatment over other traffic.
