    CCNA Composite Exam

    The 200-120 CCNA exam is the composite exam associated with the CCNA Routing and

    Switching certification. Candidates can prepare for this exam by taking the Interconnecting

    Cisco Networking Devices Part 1 (ICND1) v2.0 and the Interconnecting Cisco Networking

    Devices Part 2 (ICND2) v2.0 courses. This exam tests a candidate's knowledge and skills

    required to install, operate, and troubleshoot a small to medium-size enterprise branch network.

    The topics include all the areas covered under the 100-101 ICND1 and 200-101 ICND2 exams.

    About This Study Guide

    This Study Guide provides all the information required to pass the 200-120 CCNA exam. It

    however, does not represent a complete reference work but is organized around the specific skills

    that are tested in the exam. Thus, the information contained Study Guide is specific to the 200-

    120 exam and not to Cisco Certified Network Associate entirely. It includes the information

    required to answer questions related to CCNA that may be asked during the exam. Topics

    covered in this Study Guide includes operation of IP data networks, LAN switching

    technologies, IP addressing, IP routing technologies, IP services, network device security,

    troubleshooting, LAN switching technologies, IP Routing technologies, IP services,

    troubleshooting and WAN technologies.

    Intended Audience

    This Study Guide is targeted specifically at network administrator, network engineer, network

    manager and systems engineer. This information in this Study Guide is specific to the exam and

    is not a complete reference work.

    Good luck!
