Exam Code: 200-120

Certifications:

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!
