Cisco Maintaining Cisco Service Provider Quality of Service (MSPQS) Sample Questions:

1. A provider plans to use IP SLA to help diagnose future performance issues in their PE routers in the network. Which two should be considered by the provider? (Choose two.)

A) IP SLA should use a mix of source and target points.
B) IP SLA is supported only on Cisco IOS edge routers, because it simulates traffic from the network endpoints.
C) IP SLA requires a significant amount of resources to operate properly. Using IP SLA on the PE routers will only aggravate performance-related issues the network already encounters.
D) IP SLA should be implemented on dedicated hardware to properly simulate network endpoints.

2. Which Cisco IOS XR command will help troubleshoot why a policy map fails to apply on an interface?

A) show qos interface tenGigE 0/0/0/0
B) show policymgr qos trace all
C) clear qos counters
D) show service-policy interface tenGigE 0/0/0/0
E) show policy-map interface tenGigE 0/0/0/0

3. When the RFC 3270 Short Pipe mode is used, the PHB at the egress router is based on which of these?

A) The Differentiated Services Field value in the IP packet header.
B) The packet is re-evaluated, remarked, and the PHB is based on this new marking.
C) The MPLS VPN label EXP value.
D) The topmost MPLS label EXP value.

4. A service provider recently changed from RFC 3270 Uniform mode to Pipe mode. Which three considerations about this change are true? (Choose three.)

A) If the provider moved to a Short Pipe mode model, it would allow them to implement customer-specific QoS policy on the PE egress.
B) In Uniform mode, when the topmost EXP value is changed, the changed EXP value will propagate to the original IP precedence or DSCP.
C) The Pipe mode provides the isolation between the customer and provider DiffServ domains, while maintaining a simpler support model.
D) The Short Pipe mode derives the outbound classification of the WRED and WFQ based on the DiffServ policy of the provider.

5. A customer with an unmanaged CE router has reported experiencing poor quality on the video conferencing and broadcast multimedia applications. To address the issue, the provider has implemented shaping on the PE router to "smooth out" speed mismatches in the network. Which of these is a valid concern with this approach?

A) While shaping may help the broadcast multimedia application, it could cause additional delay in the video conferencing application.
B) Shaping can only be applied to the outbound interface, which does not prevent the customer from flooding the inbound link to the provider.
C) In addition to shaping, the provider should implement policing so the application can detect the congestion and throttle traffic.
D) Shaping should only be used in a TCP-based environment where the application can detect the congestion and adjust. Shaping provides little benefit with UDP applications.
