Q. What is a CCNA?
A CCNA (Cisco Certified Network Associate) is someone who has successfully passed the CCNA technical certification exam provided by Cisco Systems.
Q. What does a CCNA do?
CCNA certified professionals can install, configure, and operate LAN, WAN, and dial access services for small networks (100 nodes or fewer), including but not limited to use of these protocols: IP, IGRP, IPX, Serial, AppleTalk, Frame Relay, IP RIP, VLANs, RIP, Ethernet, Access Lists.

CCNAs are expected to be competent in handling a variety of technical tasks related to Cisco routers and switches:
•System Configuration and Maintenance
•Network Architecture
Q. What do all those terms mean?
Troubleshooting—Probably your most important task, this is the ability to diagnose and correct system and network problems.
System Configuration and Maintenance—Be able to install, maintain, and upgrade Cisco IOS (Internetwork Operating System) software.
Network Architecture—This refers to network topology (the physical layout of a network); routing; IP addressing; VLANS (virtual LANs); etc.
Security—This task deals with controlling data flow via firewalls and access lists.
