The Cisco 100-490 Routing and Switching Training Course is designed as a focused training course for learners who want to build a solid understanding of the retired Cisco Certified Technician Routing and Switching exam while developing practical, exam-oriented networking knowledge. Although the 100-490 exam is no longer active, many candidates and professionals continue to study this certification as a foundational learning reference for entry-level Cisco networking skills. This training course positions the former exam objectives into a structured, self-paced learning experience that supports exam preparation, conceptual understanding, and long-term skill development using officially published exam domains.

This training course is built around the original Cisco 100-490 RSTECH exam objectives and aligns with the knowledge areas that were required for on-site support of Cisco routing and switching devices. Learners progress through a structured study plan that reflects how the exam was organized, covering essential topics such as network fundamentals, Cisco router and switch components, cabling and interface basics, device startup and configuration concepts, and common Layer 1 and Layer 2 troubleshooting scenarios. Each topic is explained through exam-focused knowledge explanations that help learners understand not only what the technology does, but also why it behaves the way it does in real-world support situations.

As a training course provided through AAAdemy, the learning experience emphasizes clarity, structure, and exam relevance. The learning material is organized into clearly defined study sections that map directly to the retired exam blueprint, allowing learners to follow a logical progression from basic concepts to applied troubleshooting knowledge. Exam guide explanations are written to support self-study and are especially useful for candidates who are new to Cisco environments or who want to reinforce their understanding of routing and switching fundamentals without relying on live instruction or video-based learning.

This training course also includes learning methods and exam strategies tailored specifically to the former 100-490 exam format. Learners are guided on how to interpret exam-style questions, how to identify key technical details in scenario-based prompts, and how to manage time effectively during an exam attempt. To support knowledge validation, the training course incorporates online practice questions and online practice activities that reflect the structure and difficulty level of the retired exam, helping learners assess readiness and identify areas for further review.

While the 100-490 certification has been retired by Cisco, this training course remains a valuable study guide and learning resource for understanding Cisco routing and switching concepts at the technician level. It is particularly suitable for learners seeking exam preparation practice, structured learning material, and foundational networking knowledge presented in a clear, exam-focused format. By combining a structured study plan, detailed knowledge explanations, exam strategies, and online practice questions, this training course delivers a comprehensive and self-paced learning solution for those studying the Cisco Routing and Switching exam.
