Optimizing Converged Cisco Networks
Last day to test: July 31, 2010
Cost: 150$
Duration : 90 minutes (50-60 questions)
Available Languages : English, Japanese

Exam Description

The Optimizing Converged Cisco Networks (642-845 ONT) is a qualifying exam for the Cisco Certified Network Professional CCNP®. The ONT 642-845 exam will certify that the successful candidate has important knowledge and skills in optimizing and providing effective QOS techniques for converged networks. The exam topics include implementing a VOIP network, implementing QoS on converged networks, specific IP QoS mechanisms for implementing the DiffServ QoS model, AutoQoS, wireless security and basic wireless management.

Exam Topics‍

Describe Cisco VoIP implementations

  • Describe the functions and operations of a VoIP network (e.g., packetization, bandwidth considerations, CAC, etc.).
  • Describe and identify basic voice components in an enterprise network (e.g. Gatekeepers, Gateways, etc.)

Describe QoS considerations

  • Explain the necessity of QoS in converged networks (e.g., bandwidth, delay, loss, etc.).
  • Describe strategies for QoS implementations (e.g. QoS Policy, QoS Models, etc.).

Describe DiffServ QoS implementations

  • Describe classification and marking (e.g., CoS, ToS, IP Precedence, DSCP, etc.).
  • Describe and configure NBAR for classification.
  • Explain congestion management and avoidance mechanisms (e.g., FIFO, PQ, WRR, WRED, etc.).
  • Describe traffic policing and traffic shaping (i.e., traffic conditioners).
  • Describe Control Plane Policing.
  • Describe WAN link efficiency mechanisms (e.g., Payload/Header Compression, MLP with interleaving, etc.).
  • Describe and configure QoS Pre-Classify.

Implement AutoQoS

  • Explain the functions and operations of AutoQoS.
  • Describe the SDM QoS Wizard.
  • Configure, verify, and torubleshoot AutoQoS implementations (i.e., MQC).

Implement WLAN security and management

  • Describe and Configure wireless security on Cisco Clients and APs (e.g., SSID, WEP, LEAP, etc.).
  • Describe basic wireless management (e.g., WLSE and WCS). Configure and verify basic WCS configuration (i.e., login, add/review controller/AP status, security, and import/review maps).
  • Describe and configure WLAN QoS.
