Cisco Maintaining Cisco Service Provider Quality of Service (MSPQS) Sample Questions:
1. Refer to the exhibit.
Your MPLS network is using RFC 3270 Uniform mode. Your customer reports that when a Microsoft NetMeeting call is placed between the workstations, the user at 172.16.1.2 experiences acceptable audio quality but the user at 172.16.2.2 experiences poor audio quality. What course of action should you take?
A) Use a policy map at the ingress to the PE1 router to remark packets from 172.16.1.2.
B) Use a policy map at the ingress to the PE2 router to remark packets from 172.16.2.2.
C) Have the customer set the correct marking of audio packets at the 172.16.1.2 device.
D) Change your policy to not remark audio packets within your network.
E) Have the customer set the correct marking of audio packets at the 172.16.2.2 device.
2. Which Cisco IOS IP SLA Probe would you select to identify bottlenecks in the network?
A) ICMP Echo
B) FTP Path Echo
C) ICMP Path Echo
D) ICMP Path Jitter
3. DRAG DROP
Drag the definitions from the left onto the traffic classification on the right. Not all definitions will be used.
4. Where would you apply WRED to avoid congestion and poor QoS from oversubscription of the network?
A) wherever there is a potential bottleneck and most traffic is UDP
B) wherever there is a potential bottleneck
C) wherever there is a potential bottleneck and most traffic is voice
D) wherever there is a potential bottleneck and most traffic is TCP
E) wherever there is a potential bottleneck and traffic is delay-intolerant
5. Refer to the exhibit.
You have implemented RFC 3270 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) CS1
B) CS4
C) BE
D) CS3
E) AF31
