The Cisco Certified Network Professional 4 (CCNP 4) is just the right module for those students who are interested to become network administrators, Level 2 support engineers, network technicians and deployment engineers. It is part of a four-module curriculum under the CCNP curriculum. What is CCNP4? CCNP4 is specifically about network troubleshooting competencies. The areas of specialization are TCP/IP, LAN Switching, VLANs, Frame Relay, ISDN, Appletalk, Novell, BGP, OSPF, EIGRP and OSI Layers 1, 2 and 3. Upon completion of this course, the students will be able to find solutions to problems in the said areas.
