Cisco 400-101 FAQs: What Every Candidate Asks
The 400-101 exam, officially titled CCIE Routing and Switching Written Exam, is the qualifying test for the CCIE Routing and Switching certification from Cisco, a credential at the Expert level. Passing it proves you have the skills employers look for in certified professionals, and it can also support progress toward related credentials such as CCIE Routing and Switching, CCIE.
The Cisco CCIE Routing and Switching Written exam gives you 120 minutes to work through 90–110 questions. That is a steady pace with little room for second-guessing, so train yourself to read each question once, flag the difficult ones, and keep moving. Before exam day, sit at least two full timed sessions in the Fast2test test engine — when the clock feels familiar, it stops being a threat.
You need 790 / 1000 scaled score to pass, and the official registration fee is $400 USD. Fall short and you pay that fee in full again for every retake, which makes solid preparation the cheaper option by far. Work through the Fast2test practice questions until you score comfortably above the passing mark, then book your seat.
No formal prerequisites; written exam required before attempting CCIE Routing and Switching Lab Exam Eligibility rules can change over time, so before you register, confirm the latest requirements on the official exam page: Cisco 400-101 exam overview.
You can book your 400-101 exam through any of these official registration channels:
