The 642-785 Maintaining Cisco Service Provider Quality of Service (MSPQS) exam is the exam associated with the CCNP SP Operations certification. This exam tests a candidate's knowledge of QoS mechanisms to support Service Provider networking environments, including how they are monitored, implemented, and troubleshot using both Cisco IOS and IOS XR operating systems. Furthermore, it assesses a candidate's ability to manage performance and capacity based on QoS statistics gathered from a SP IP NGN environment.Candidates can prepare for this exam by taking the MSPQS Maintaining Cisco Service Provider Quality of Service course.

                operating center (NOC) environment

      • 2.1   Use industry standard network management to
                monitor and diagnose QoS
      • 2.2   Issue standard CLI commands in Cisco IOS and
                Cisco IOS XR Software for monitoring
                QoS operations
      • 2.3   Use IP SLA to monitor traffic performance and diagnose QoS
      • 2.4   Use Netflow to monitor traffic performance
      • 2.5   Analyze statistics based on traffic classes and patterns
      • 2.6   Given a QoS policy ticket that accurately defines
                an issue, describe the adverse effects
                that might result from a fix
  • 40%     3.0   Troubleshoot QoS in an IP NOC environment

      • 3.1   Describe the state of QoS on the router
                or interfaces using statistical data gathered from
                MIBs and from various IOS commands
      • 3.2   Describe the effects on the network traffic
                based on given IOS QoS configurations
      • 3.3   Perform and interpret packet capture to address
                a customer issue
      • 3.4   Given a particular customer complaint,
                describe the actual QoS problem
      • 3.5   Given a QoS problem, produce a recommended policy
                change and change order to fix the problem
      • 3.6   Recognize typical QoS issues for different provider
                edge-customer edge (PE-CE) connection types
      • 3.7   Recognize typical end-to-end QoS MPLS VPN issues
  • The following course is the recommended training for this exam.
