The CCNA curriculum consists of two equally-weighted 5-day courses - ICND1 and ICND2.

Both courses are based on a common topology featuring updated Cisco equipment and IOS, including ISR routers. Coverage of troubleshooting has been extended beyond installation to day-two operations, coverage of security has been enhanced, and an introduction to wireless concepts and terminology has also been included. Both courses offer more compelling lab exercises and include more time for hands-on practice and labs—roughly 30% to 50%.
