Cisco 400-101 Exam: Your Questions, Answered

The Cisco CCIE Routing and Switching Written exam is the official Cisco assessment behind the CCIE credential, which sits at the Expert level. Passing it confirms that your skills meet the vendor's current requirements rather than a textbook outline. It also connects with related certifications such as CCIE Routing and Switching, so it can anchor a broader certification path.

According to the official exam information, the Cisco CCIE Routing and Switching Written exam includes 90-110 questions and gives you 120 minutes to complete them. Treat that as a pacing exercise, not just a knowledge check: bank the questions you know first, flag the ones that stall you, and circle back instead of burning minutes on a single item. Before test day, run at least one full timed session in the Actual4Cert desktop or online test engine, so the clock never feels unfamiliar when it counts.

To pass the Cisco CCIE Routing and Switching Written exam you need Variable (Cisco does not publish passing scores), and the official registration fee is USD 450. Keep one thing in mind: a failed attempt is not discounted, so retaking the exam means paying USD 450 again in full. A practical safeguard is to sit a complete Actual4Cert practice test a week or two before your exam date; if your timed scores are not sitting comfortably above the passing mark, consider pushing your booking back and drilling the weak domains first.

The official prerequisites for the Cisco CCIE Routing and Switching Written exam are as follows: No formal prerequisite. Passing this written exam qualified candidates to attempt the CCIE Routing and Switching Lab Exam.. Requirements can change over time, so confirm the details on the official Cisco exam page at https://learningnetwork.cisco.com/community/certifications/ccie-routing-switching before you book your seat.
