Supporting Cisco Routing and Switching Network Devices v3.0 (100-490) is a comprehensive course designed to prepare candidates for the Cisco Certified Technician Routing and Switching certification exam. This 90-minute exam, consisting of 60-70 questions, tests the skills required for onsite support and maintenance of Cisco routers, switches, and operating environments.Technicians will learn to identify Cisco router and switch models, accessories, cabling, and interfaces. They will understand Cisco IOS software operating modes, identify commonly found software, and use the Cisco Command Line Interface (CLI) to connect and service products. Achieving this certification is considered the best foundation for supporting other Cisco devices and systems. The exam is closed book, and no outside reference materials are allowed.The following topics are general guidelines for the content likely to be included on the exam. However, other related topics may also appear on any specific delivery of the exam. The guidelines below may change at any time without notice to better reflect the contents of the exam and for clarity purposes.Exam Content Guidelines:1.0 General Networking (23%) 1.1 Use the OSI and
