CNT 101 - Network Fundamentals
Study of the devices and protocols used to connect computers and support devices into a network. Topics include; OSI model (layers 1 & 2), IP and MAC addresses, TCP, ARP, and RARP. The function of soft hubs, switches and routers are compared and contrasted. Media design, structured cabling, and network management are also covered. This course is the first of four that prepares students for the Cisco Certified Network Associate degree or certification.

CNT 102 Routing Protocols and Concepts
Prerequisites: CNT 101; with a grade of C or better
Study of routers, their configuration, and their place in networking. Topics include: OSI model (all layers), routing principals (usage, components, startup, setup, and configuration). The difference between routed and routing protocols also is covered. This course is the second of four that prepares students for the Cisco Certified Network Associate.

CNT 103 LAN Switching/Wireless Communication 
Prerequisites: CNT 102; with a grade of C or better
Study of Local Area Networks. Topics include: LAN switching, Virtual LANS, LAN design, Access lists, IGRP, and IPX. Each subject is explored through the use of threaded case studies. This course is the third of four that prepares students for the Cisco Certified Network Associate degree.

CNT 104 Accessing the WAN
Prerequisites: CNT 104; with a grade of B or better
Study of Wide Area Networks. Topics include: WAN principles/design, PPP, ISDN, and Frame Relay. Each subject is explored through the use of threaded case studies. Also includes a review in preparation for the CCNA exam. This course is the last of four that prepares students for the Cisco Certified Network Associate.

CNT 205 Building Scalable Internetworks
Prerequisite: CNT 104 or CCNA certification

This class will introduce advanced routing protocols required on scalable networks. Topics include: OSPF, EIGRP, and BGP operations and configuration. Course addresses those tasks that network managers and administrators need to perform when managing access and controlling overhead traffic in growing routed networks. Discuss router capabilities used to control traffic over LANs and WANs, as well as connecting corporate networks to an Internet service provider (ISP). The class is designed to prepare students to pursue the Cisco CCNP examination.

CNT 206 Implementing Secure Converged WAN 
Prerequisite: CNT 104 or CCNA certification
This course teaches students how to build a remote access network to interconnect central sites to branch offices and home office/telecommuters. Once the network is built, the course teaches students how to control access to the central site, as well as maximizes bandwidth utilization over the remote links. The class is designed to prepare students to pursue the Cisco CCNP examination.

CNT 207 Building Multilayer Switched Networks
Prerequisite: CNT 104 or CCNA certification
This course teaches network administrators how to build campus networks using multilayer-switching technologies over a high-speed Ethernet. The class will include an overview of SPT, bridging, switching, and VLAN management. Students also will design, configure, and troubleshoot multi-layered switched and routed networks. The class is designed to prepare students to pursue the Cisco CCNP examination.

CNT 208 Optimizing Converged Networks
Prerequisite: CNT 205, CNT 206, and CNT 207
This courses teaches students how to baseline and troubleshoot a LAN and WAN environment. Students learn to test and identify problems with routers and switches in multi-protocol environments. Topics include: Ethernet, Fast Ethernet, and Token Ring LANs; and serial, frame, relay, and ISDN BRI WANs. The class is designed to prepare students to pursue the Cisco CCNP examination.
