You're looking at 45-55 questions in 90 minutes. Do the math early, not in the exam room: decide your per-question pace, practice skipping hard items without panic, and finish at least two full timed mock tests — the Actual4Dumps engine grades them automatically in about a minute, so you get instant feedback on where your time goes.
Delivery is the easy part: pay, click the email link that arrives within a minute, and the 100-105 files download in about a minute — no extra software, no installation limits. If 2 hours pass with nothing, our support team will fix it. The refund side runs on clear rules: take the corresponding 100-105 exam within 60 days of purchase, and if you fail, submit a scanned enrollment slip plus the official Score Report PDF within 2 days of the exam for a 100% refund, processed within 7 days. Exams sat within 3 days of purchase don't qualify, candidate and payer names must match, and free or expired products are excluded. Prefer an exchange? Take two equal-value exam products free of charge and keep your original updates.
You need 832/1000 to pass, and registration costs $165 USD at the official rate. One uncomfortable truth: the fee is per attempt, so a fail means paying it again. Candidates who self-test first — with auto-graded mock exams built from the 832 questions at Actual4Dumps — tend to pay that fee exactly once.
The vendor's blueprint for the Cisco Interconnecting Cisco Networking Devices Part 1 (ICND1 v3.0) has 5 domains, led by Infrastructure Maintenance (14%), Routing Fundamentals (25%), Network Fundamentals (20%). The weighting is a study plan in disguise — heavy domains deserve heavy hours. You'll find every domain and subtopic in the complete outline above.
Passing the 100-105 exam earns the ICND1 certification — a Associate-level credential — issued directly by Cisco. It is proof of ability that travels well across employers and borders. The credential also links to CCENT, CCNA Routing and Switching, so it can be a first step rather than a final destination.
Yes — the free PDF demo shows the real question quality before any payment. And the value continues after purchase: 365 days of free updates come standard, with a 50% renewal discount if your update period ever expires.
