CCNA is an entry or "apprentice" level networking certification. Cisco created the CCNA to recognize basic competency in computer networking, particularly for installation and support of LAN/WAN networks having 100 nodes or fewer. The CCNA covers both IP and non-IP networks including Novell IPX and AppleTalk. Obtaining the CCNA requires passing a single certification exam.The CCNA exam, newly revised in 2002, contains 55-65 questions and lasts approximately 90 minutes. It now costs $125 (USD) to sit the exam. Although the CCNA has no formal prerequisites, one must effectively complete hundreds of hours of study to prepare. Primarily, one must understand basic routing and switching as they relate to network design, performance and security.
