Course Overview :

Cisco Certified Internetwork Professional (CCIP) 642-642 QOS

Course Title: Implementing Cisco QOS

Course Code: QOS 642-642
Duration: 5 Days

Course Overview

The Implementing Cisco QOS (QOS) training course has been designed to provide candidates with an in-depth knowledge of the IP QoS requirements, conceptual models using Differentiated Services (Diffserv), Integrated Services (IntServ) and Best Effort (over provisioning), and the implementation of IP QoS on Cisco IOS switch and router platforms. The case studies and lab exercises included in the course help students to apply the concepts mastered in individual modules to real-life scenarios.

Target Audience

Candidates who should consider attending the QOS 642-642 Cisco training course include network designers and engineers responsible for implementation and management of IP QoS as well as students seeking Cisco CCIP and CCVP Certification.

Course Objectives

On successfully completing the QOS 642-642 course you will be able to:
  • Explain the need to implement QoS and explain methods for implementing and managing QoS
  • Identify and describe different models used for ensuring QoS in a network and explain key IP QoS mechanisms used to implement these models
  • Explain the use of MQC and AutoQoS to implement QoS on the network
  • Classify and Mark network traffic in order to implement a defined QoS Policy
  • Use Cisco queuing mechanisms to manage network congestion
  • Use Cisco QoS congestion avoidance mechanisms to reduce the effects of congestion on the network
  • Use Cisco QoS traffic policing and traffic shaping mechanisms to effectively limit the rate of network traffic

Course Prerequisites

Candidates attending the QOS 642-642 Cisco training course should hold a valid CCNACertification. Candidates are also recommended to attend BGP before attending this course.

Testing and Certification

The QOS Cisco training course is the recommended preparation for the 642-642 QOS - Implementing Cisco QOS. QOS 642-642 is only one of four courses required for CCIP Certification and Troubleshooting Unified Comms (TUC), Implementing Cisco Voice Gateways and Gatekeepers (GWGK), MPLS, CVOICEV8, CIPT1V8 and CIPT2V8 are recommended for further study. Please note that QOS is part of the CCIP Certification and Voice Certifications as well as the Cisco Qualified Specialist Voice Specialisations and ROUTE, QOS, BGP and MPLS are also required for the CCIP Certification.
