CCNA is the first of the many certifications needed for a full Cisco career. There are four CCNA courses that need to be finished. The last one, CCNA 4, has six modules.
Module 6 will give you an introduction to network administration. This will cover topics like workstations, servers, client-server relationship, NOS, MSNT, .NET, network management, MIBs, SNMP, RMON, and many more.
If we look at the history of the PC, it was originally designed as a standalone system with the operating system allowing only one user at a time o access files and data.
However, with companies integrating their programs and making PC-based networking access a common feature in their services, many software companies developed an operating system for the network. The features and advancements of
NOS technology is lengthily discussed in the CCNA 4 module 6.
Network administration in module 6 of CCNA 4 includes an extensive discussion on the importance of network connectivity and operating, configuring and troubleshooting them on different operating systems so that only the correct solutions
are used. Because more services are now available to a multitude of users, network performance can and will suffer. CCNA 4 Module 6 will help candidates maintain a productive environment in their networking duties by teaching them how to effectively manage LANs and WANs.
Upon the completion of CCNA 4 Module 6, the candidate is expected to identify the potential tasks done by workstations as well as the functions of the server; describe the roles of equipment in the environment of client/server while also differentiating between NOS and a desktop OS. This is the basic introduction to network administration of CCNA 4 Module 6.
