Plan on needing 790 / 1000 scaled score to pass the 400-101 exam, and budget $400 USD for the official registration. Treat that fee as single-use: a failed attempt means paying the same amount again for a retake. The cheapest insurance policy is preparation — cycle through the 150 practice questions at Actual4Dumps until your timed mock results clear the passing mark consistently, and only then schedule your exam.
For the Cisco CCIE Routing and Switching Written, Cisco points candidates toward these resources:
Training builds the foundation; deliberate practice builds the pass. Layer the 150 practice questions from Actual4Dumps on top of any course above, and you cover theory and execution in one plan.
The Cisco CCIE Routing and Switching Written blueprint spans 7 domains. The heaviest hitters include Infrastructure Security (10%), Evolving Technologies (10%), and VPN Technologies (10%). The complete breakdown — every domain and subtopic — is laid out in the syllabus section above, and that is the map your study sessions should follow.
Expect 90–110 questions and 120 minutes on the clock for the 400-101 exam. Time management is a skill of its own here: candidates who untimed-study often discover the real pressure only when the countdown starts. Build that muscle memory early — run full timed simulations in the Actual4Dumps desktop or online test engine, practice flagging and skipping, and let pacing become reflex before exam day.
Delivery takes seconds, not days: your download is live immediately after checkout, and a copy reaches your email within one minute. If nothing lands within 2 hours, check the spam folder and message our support team. You may install the software on as many computers as you like — no device cap, ever.
If you sit the 400-101 exam within 60 days of purchase and the result is a fail, the Actual4Dumps money back guarantee has you covered: file within 2 days of the exam with a scan of your enrollment slip and the official score report (PDF), and the claim is processed within 7 days. The candidate name must match the payer name; exams taken within 3 days of purchase, purchases never used in an actual attempt, free materials, and expired orders fall outside the policy. Not interested in a refund? Exchange the product for two free exam packages of equal value and keep the update service on your original purchase.
Formally known as the CCIE Routing and Switching Written Exam, the 400-101 exam is Cisco's way of certifying that you can apply its technologies to real-world problems — pass it, and you hold the CCIE Routing and Switching certification, a Expert-level credential. Because it is vendor-backed and skills-driven, employers treat it as proof rather than promise. It also feeds into a wider path that includes CCIE Routing and Switching, CCIE.
