Exam Description: The Interconnecting Cisco Networking Devices Part 1 (ICND1) exam (100-105) is
a 90-minute, 45–55 question assessment that is associated with the Cisco Certified Entry Network
Technician (CCENT) certification and is a tangible first step in achieving other associate-level
certifications. This exam tests a candidate's knowledge and skills related to network fundamentals, LAN
switching technologies, routing technologies, infrastructure services, and infrastructure maintenance.
The following topics are general guidelines for the content likely to be included on the exam. However,
other related topics may also appear on any specific delivery of the exam. In order to better reflect the
contents of the exam and for clarity purposes, the guidelines below may change at any time without
