CCNA3: Scaling Networks

CCNA3: Scaling Networks for cable professionals is the third of four courses that may be used to prepare for the Cisco Certified Network Associate (CCNA) exam. CCNA3 describes the architecture, components, and operations of routers and switches in a larger and more complex network. Students learn how to configure routers and switches for advanced functionality. By the end of this course, students will be able to configure and troubleshoot routers and switches and resolve common issues with OSPF, EIGRP, STP, and VTP in both IPv4 and IPv6 networks. Students will also develop the knowledge and skills needed to implement DHCP and DNS operations in a network.

                    

CCNA3 introduces SCTE students to intermediate level networking concepts and technologies using a hands-on approach, with an emphasis on cable operator operations.  In addition, the course will assist the student in developing the skills necessary to plan and implement switching and routing polices. SCTE courses emphasize critical thinking, problem solving, collaboration, and the practical application of skills.  

By the end of this course, students will be able to configure and troubleshoot routers and switches and resolve common issues with EIGR, single and multi-area OSPF, gateway redundancy protocols HSRP, VRRP and GLBP and link aggregation PAgP and LACP

Format: Online, Self-Paced Scheduled:

This course is expected to take 12 weeks to complete online, 5 days onsite for a total of 40 hours. Learners view online interactive materials and complete learning activities at a time that is convenient for the learner. Scheduled virtual online instructor coaching sessions will be optional, but participation is strongly suggested by SCTE/ISBE to provide direct interaction with the certified instructor. However, if the learner is unable to attend, these sessions are recorded. The coaching session times are determined by the students and instructor during the orientation that is held on the first day of the course.  Learners spend approximately 6-8 hours per week completing the various course activities.

Access information will be emailed when the course is purchased.
