CCNA: Routing and Switching Exam 200-125

Course Code



5 Days

Due to the pace and duration of this course, ideal candidates operate in medium to large computing environment:

  • They have a minimum of one-year experience working in a LAN/WAN environment
  • They have passed the Network+ course and certification exam and/or possess this knowledge

Participants in this course will learn how to install, operate, configure, and verify a basic IPv4 and IPv6 network, including configuring a LAN switch, configuring an IP router, managing network devices, and identifying basic security threats. The goal of the course is to provide you with the knowledge and skills necessary to install, configure, and operate a small- to medium-sized network. Participants of this accelerated course are provided knowledge and skills to install and configure Cisco IOS routers and switches in a multi-router network that uses LAN and WAN interfaces for the most commonly used routing protocols. The CCNA is considered to be the most universally rewarding certification produced in the IT industry. Individuals who possess a CCNA usually carry job titles such as Network Engineer or Network Architect. This class will utilize Dynamips which is a software simulator.

Course Materials consist of a CCNA participant manual and the following materials:

  • The Cisco Certified Network Associate Routing and Switching textbook and CCNA Virtual Lab e-trainer

Cisco e-trainer simulator software will be utilized with several routers and switches

Exam Preparation
Completion, review and discussion of examination question examples.

Domains of Exam
Planning and Design, Implementing and Operation, Technology, and Troubleshooting

Within the four domains, Cisco will ask questions dealing with Internetworking, Ethernet networks and data encapsulation, TCP/IP, subnetting, VLSMs, Summarization, and troubleshooting TCP/IP. You will also be testing on the Cisco IOS, Managing a Cisco Internetwork, Managing Cisco Devices, IP routing with static, default, and dynamic routing protocols (RIP, EIGRP, OSPF, and BGP). Topics include Layer 2 switching, and VLANs, and Inter-VLAN routing, security, ACL’s, NAT, and troubleshooting IPv4, IPv6, and VLANs, WANs, and the evolution of Intelligent Networks. Both IPv4 and IPv6 are covered on this exam for EIGRPv6 and OSPFv3 (for IPv6).

Criteria for Certification
