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

1. 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) decreases the probability of congestion by selectively dropping TCP packets before the queue is full
B) decreases congestion by avoiding global UDP synchronization
C) provides congestion management by queueing the traffic using LLQ
D) provides congestion avoidance by selectively delaying the delivery of packets with lower DSCP priority
E) provides congestion management by queueing the traffic using CBWFQ

2. A customer reports that during peak hours, FTP performance is unacceptable. Currently, the service provider maps the customer FTP traffic into the class-default traffic class and FTP traffic is marked with MPLS EXP1. The class-default class traffic is configured with MPLS EXP based WRED and also with the bandwidth command. What could be causing the FTP performance issues with the customer?

A) FTP packets are being more randomly dropped that the other TCP traffic within the class-default traffic class, because the WRED thresholds for MPLS EXP 3 marked packets were configured to improper values.
B) The service provider is using LLQ on all the core links, but the FTP traffic is not is assigned to the priority queue.
C) The FTP-type bulk traffic should be mapped to MPLS EXP 5 instead of MPLS EXP 1. The improper marking of FTP packets is causing CBWFQ to assign lower priority for FTP packets within the class-default traffic class.
D) The bandwidth command is causing the FTP issues. It is generally not recommended to use CBWFQ for the class-default traffic class.

3. The provider you work for supports a wide range of Cisco router models and Cisco IOS Software releases. You are in the process of moving to a SNMP-based tool to monitor QoS configurations and statistics. What are some of the challenges to this approach?

A) SNMP should be used in conjunction only with Cisco IP SLA to ensure that the information gathered is reported properly.
B) Older versions of Cisco IOS Software do not maintain index persistency, which results in significant changes in the information that is collected unless properly configured.
C) The SNMP MIB provides direct access into the QoS configuration parameters. Poor configuration could lead to changes that are difficult to track.
D) Some models of Cisco routers do not have full support for the class-based QoS MIB, which results in a number of elements that cannot be managed.

4. An MPLS VPN customer reports that the VoIP voice quality is very bad for calls across the
MPLS VPN. What could be the problem?

A) Traffic shaping is applied to the voice traffic class.
B) The voice packets are marked as DSCP EF.
C) WRED is not configured for the voice traffic class.
D) The voice traffic class is using the default queue size.
E) The voice traffic class is using the priority command.

5. Refer to the exhibit.

A provider uses the recommended mappings for DSCP to MPLS EXP. Several sites connected to the same PE router report that critical data has been experiencing a high number of drops. The customer marks its CRITICAL data as AF31. What appears to be the problem?

A) The provider is using the recommended mappings for DSCP to MPLS EXP, so the CLASS-MAP for the CRITICAL-DATA should contain EXP value of 4.
B) The allocated bandwidth for CRITICAL-DATA should be increased to provide sufficient bandwidth to support the application.
C) The classification for CRITICAL-DATA should contain a match-all, not a match-any.
D) If the data receiving drops is high priority, it should be marked with MPLS EXP value 7.
E) The recommended mapping for AF31 is to MPLS EXP 5, which is classified in the REALTIME class, not the CRITICAL DATA class.
