Exam Description
The Introduction to Cisco Networking Technologies exam is one of the two qualifying exams available to candidates pursuing a two-exam option for CCNA. This exam tests content covered in the Introduction to Cisco Networking Technologies (INTRO) course including topics on Network Types, Network Media, Switching Fundamentals, TCP/IP, IP Addressing and Routing, WAN Technologies, Operating and Configuring IOS Devices, and Managing Network Environments. The exam will certify that the successful candidate has important knowledge and skills necessary to describe and identify major network and WAN components, along with their function and purpose.

Exam Topics
The following information provides general guidelines for the content likely to be included on the Introduction to Cisco Networking Technologies exam. However, other related topics may also appear on any specific delivery of the exam.
Design and Support
Use a subset of Cisco IOS commands to analyze and report network problems
Use embedded layer 3 through layer 7 protocols to establish, test, suspend, or disconnect connectivity to remote devices from the router console
Determine IP addresses

Implementation and Operation
Establish communication between a terminal device and the router IOS, and use IOS for system analysis
Manipulate system image and device configuration files
Perform an initial configuration on a router and save the resultant configuration file
Use commands incorporated within IOS to analyze and report network problems
Assign IP addresses
Describe and install the hardware and software required to be able to communicate via a network
Use embedded data link layer functionality to perform network neighbor discovery and analysis from the router
