This free 100-150 practice test mirrors the structure and difficulty of the real Cisco Certified Support Technician - Networking exam. Every question is written against the official 2026 exam blueprint published by Cisco, ensuring you practise exactly what the exam tests — not last year's objectives.
The 100-150 blueprint is divided into 6 weighted domains. Questions on this page are distributed proportionally across each domain, so the mix you see here reflects the same weighting you'll face on exam day. High-weight domains like Standards and Concepts and Addressing and Subnet Formats contribute the most questions, meaning focused practice on these areas gives you the highest return on study time.
100-150 Exam Blueprint — 6 Domains
Standards and Concepts
Addressing and Subnet Formats
Diagnosing Problems
Infrastructure
Security
Endpoints and Media Types
23 numbered sets, 6 domain question banks, and targeted sessions — every page is a unique set of questions.
Choose all correct answers
Each chapter page covers one topic in depth — theory, key concepts, and focused practice questions. Use these to close knowledge gaps before returning to full practice tests.
Getting the most from practice questions requires more than just clicking through answers. Here is the study method used by candidates who pass 100-150 on their first attempt:
Answer before revealing
Read each 100-150 question fully, eliminate obviously wrong choices, then commit to an answer before clicking to reveal. This active recall process is what builds lasting knowledge.
Read every explanation
Even when you answer correctly, read the full explanation. Knowing WHY the right answer is correct — and why the distractors are wrong — is what separates a 750 score from a 900 score.
Track weak domains
Note which 100-150 domains you get wrong most often. Then do a targeted 20-30 question session focused only on that domain until your accuracy improves.
Simulate exam pacing
The real 100-150 is 50 minutes long. Use timed sessions to build the concentration and pacing you will need on exam day.
Most candidates who pass 100-150 on their first attempt report doing between 400 and 800 practice questions over 4–8 weeks of preparation. With 297+ questions in the Courseiva bank, you have more than enough material to build that repetition without seeing the same question twice.

Answer all 20 questions to see your domain score breakdown
A structured study plan dramatically increases your chances of passing 100-150 on the first attempt. The most effective approach combines reading the official Cisco documentation or a study guide, watching video explanations for difficult concepts, and then reinforcing everything with daily practice questions.
We recommend the following weekly structure for 100-150 preparation:
Cover each 100-150 domain systematically. Read the exam objectives, watch explanatory content, and do 10–20 practice questions per domain to test understanding as you go.
Run full 50–60 question mixed sessions daily. Review every wrong answer in detail. Identify which domains are consistently scoring below 70% and revisit those study materials.
Do 100–120 question timed sessions to simulate real exam conditions. Aim for consistent scores above 80% before booking your exam date. A score above 80% in practice typically translates to a passing 100-150 score.
On exam day, the 100-150 tests your ability to apply knowledge to realistic scenarios — not just recall definitions. This is why reading explanations and understanding the reasoning behind every answer matters more than simply grinding question volume. Use the high-count sessions (100, 120) in the final weeks as your confidence benchmark.

Every question is written against the official 100-150 exam blueprint published by Cisco. Our questions follow the same wording style, scenario complexity, and answer structure as the actual exam. They are original questions — not brain dumps — so you learn the underlying concepts and reasoning, not just memorised answers. Candidates who study with brain dumps often pass but have no transferable knowledge; Courseiva questions make you genuinely competent.
Most candidates who pass 100-150 on their first attempt do 30–60 questions per day. Use the Quick 10 session for daily warm-ups when you are short on time. On study days, run a 50 or 60-question session to build stamina. Reserve 100 and 120-question sessions for the final two weeks when you want to simulate real exam conditions and benchmark your readiness.
The 100-150 covers 6 domains: Standards and Concepts, Addressing and Subnet Formats, Diagnosing Problems, Infrastructure, Security, Endpoints and Media Types. Each domain carries a different weight, so allocate your study time accordingly. The highest-weighted domains — Standards and Concepts and Addressing and Subnet Formats — should receive the most attention.
Exam dumps are memorised question-and-answer lists taken from actual exam papers, often obtained illegally and shared without Cisco's authorisation. Using them violates your NDA and Cisco's certification agreement, and can result in certification revocation. Courseiva questions are original — AI-assisted, checked against the official exam objectives, and published under the editorial oversight of an engineer with 12+ years' experience. They test the same knowledge areas using new scenarios and wording. You learn the material, not just the answers.
