CCNP:
CCNP Certification is awarded by Cisco Systems® and signifies the competency achieved in installing, configuring, and operating LAN, WAN, and dial access services in medium to large networks (500+ nodes or more), including use of these protocols: IP, IGRP, EIGRP, IS-IS, BGP, OSPF, Serial, Frame Relay, IP RIP, VLANs, RIP, Ethernet, Access Lists. CCNA is a pre-requisite for CCNP certification. The CCNP certification is awarded after successful completion of the following 4 exams

CCNA:
CCNA Certification is awarded by Cisco Systems® and signifies the competency achieved in installing, configuring, and operating LAN, WAN, Wireless LAN and Switched network services for small networks (100 nodes or fewer), including use of these protocols: IP, EIGRP, Serial, and Frame Relay. The certification exams are computer based, and conducted by Sylvan Prometric and VUE testing centers. The certification, being widely recognized, offers improved job prospects in the field of LAN, and WAN infrastructure installation and maintenance using Cisco, and compatible equipment. There are no pre-requisites for taking this exam. The only requirement being payment of exam fee, which is about US$ 125. The CCNA certification is composed of 1 (ONE) individual exam, i.e. CCNA (short form for Cisco Certified Network Associate). The exam code for the CCNA exam is 640-802. The test contains identification and situational questions, in addition to Flash based simulation questions. We have provided several of these questions at appropriate ccna certification pages on this website. Alternatively, you can achieve CCNA certification by taking two exams, namely, CCENT (Cisco Certified Entry Network Technician), and CCNA ICND2 (640-816).
