The Cisco 100-490 exam, officially titled Supporting Cisco Routing and Switching Network Devices, is the required test for earning the Cisco Certified Technician Routing & Switching (CCT R&S) certification, a credential at the Entry / Technician level. Passing it validates the skills Cisco expects from certified professionals.
The 100-490 exam includes 55-65 questions, and you have 90 minutes to complete it. Before exam day, divide the available time by the question count so you know the pace you need to hold, and practice flagging time-consuming items for review instead of stalling on a single question. Timed sessions in the Actualtests4sure test engine are the easiest way to build that rhythm before it counts.
