Cisco Maintaining Cisco Service Provider Quality of Service (MSPQS) Sample Questions:
Which statement about the MQC configuration shown here for the class-default traffic class is true?
policy-map CE-EDGE-4CLASS-OC3-POS-1
class class-default
bandwidth percent 25
!
- A. This configuration is invalid, because the class-default traffic class does not support the bandwidth command.
- B. The maximum number of packets the queue for the class-default class can hold is 64 packets using the default queue-limit.
- C. The class-default class will use WFQ instead of FIFO queueing.
- D. The bandwidth percent is referenced to the reserved bandwidth on the interface.
Correct Answer: B 🗳️
Within a QoS policy-map configuration, one of the traffic classes is configured with the random-detect dscp-based configuration command. What will that command accomplish?
- A. provides congestion avoidance by selectively delaying the delivery of packets with lower DSCP priority
- B. decreases the probability of congestion by selectively dropping TCP packets before the queue is full
- C. decreases congestion by avoiding global UDP synchronization
- D. provides congestion management by queueing the traffic using CBWFQ
- E. provides congestion management by queueing the traffic using LLQ
Correct Answer: B 🗳️
Refer to the exhibit.
Which statement is correct?
- A. This policy map is applied to the FastEthernet0/0 interface in the input direction.
- B. No traffic matched the SP-REALTIME class.
- C. A total of 133836 packets have been transmitted out of the FastEthernet0/0 interface.
- D. Packets marked with both DSCP EF and MPLS EXP 5 markings will not be classified into the SP-REALTIME traffic class.
- E. The FastEthernet0/0 interface is using CBWFQ egress queueing.
Correct Answer: C 🗳️
A customer reports drops for traffic in the BIZ-CRITICAL class. As part of the verification process you identify that there is a high number of random drops. Which of these can help address this problem?
- A. Decrease the queue limit for the traffic class.
- B. Increase the WRED min threshold value for the traffic class.
- C. Enable fair queuing for the BIZ-CRITICAL class.
- D. Decrease the WRED drop probability denominator for the class.
Correct Answer: B 🗳️
Refer to the exhibit.
You have implemented RFC 3270 Short Pipe mode in your MPLS network. A customer packet with the DSCP value of AF31 has been sent to the ingress PE router. The PE router has set the MPLS experimental bits per policy, but the policer has remarked the experimental bits of the top label. What will the DSCP value of the packet be when it leaves the egress PE router?
- A. CS3
- B. CS1
- C. AF31
- D. CS4
- E. BE
Correct Answer: C 🗳️
