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.

  1. The only way Wireless Operators can take advantage of M2M is to prvoide complete end-to-end solutions to their consumer and enterprise customers and clients rather simply rely on revenue from embedded M2M devices and sensors or rely on ecosystem partners to prvoide such solutions.The security systems initiative by AT&T launched during CTIA2012 is a step in the right direction in the consumer space. They need to do something similar in the enterprise space to seed the market.

  2. Hello Careercert,

    Just wanted to say thanks for your assistance in helping me get my CCNP. I obtained it as of last Friday 7/9. I was able to take the final test towards the CCNP – ONT. I used TI 8.11.

    Thanks again.

  3. Hi,

    Yes Testinside v8.11 – 185 Questions is the latest and it is valid. Just took ONT and passed – only 1 question was not from Test Inside.

  4. Hi,

    Testinside v8.11 – 185 Questions is it still the latest for ONT EXAM. Going next week to write my exam. Pls advise

  5. ONFUSION WITH CCNP …

    guys i passed CCNP COMPOSITE EXAM … A MONTH BACK.. NOW MY CONFUSION IS WHICH ONE TO TAKE NEXT ?

    ONT & ISCW ( THIS PAPERS I HAVE NOT YET STUDIED. SO whether IT WILL BE USEFUL IF I STUDY ISCW & ONT and TAKE THE exams.?? OR wait and take the tshoot exam???? even if i take TSHOOT.. IS IT NECESSARY TO JOIN INSTITUTES AND PREPARE FOR THIS?? OR IT WILL BE VERY DIFFICULT TO TAKE A TEST????

    gimee which one to chose

    ISCW & ONT or tshoot

  6. @ Ravi,

    In Hotspots and testlets type questions, 3-5 questions with multiple choice answers are combined in one single question. You have to answer the questions by analyzing the given topology and configuration.

    ..

  7. hello careercert..

    i have my xam of ont at end of dis month …. from where i should do the labs and hot spots … and which are the latest dumps ……

    thanx alot careercert …
