The 100-101 Interconnecting Cisco Networking Devices Part 1 (ICND1) is the exam associated with the CCENT certification and a tangible first step in achieving the CCNA Routing and Switching certification. Candidates can prepare for this exam by taking the Interconnecting Cisco Networking Devices Part 1 (ICND1) course. This exam tests a candidate's knowledge and skills required to successfully install, operate, and troubleshoot a small branch office network. The exam includes topics on the Operation of IP Data Networks; LAN Switching Technologies; IP Addressing (IPv4 & IPv6); IP Routing Technologies; IP Services (DHCP, NAT, ACLs); Network Device Security; Basic Troubleshooting.

The exam is closed book and no outside reference materials are allowed. The following topics are general guidelines for the content that is likely to be included on the practical exam.
