Simulate the real Cisco Designing Cisco Security Infrastructure (SDSI, 300-745, CCNP Security, design-focused) (SDSI) exam with full-length timed sessions. Questions drawn proportionally from all 4 official blueprint domains — the same mix you'll face on test day.
Cisco passing scores vary by exam version and are not always publicly listed. Check the official Cisco exam page before booking.
Simulate real exam conditions
For the most realistic SDSI simulation, start a 60 or 120-question session, put away all notes, set a timer matching the real exam duration (120 minutes), and commit to each answer before moving forward. This trains the time management and decision-making skills the real exam tests.
This free SDSI mock exam uses the same question distribution as the real Cisco Designing Cisco Security Infrastructure (SDSI, 300-745, CCNP Security, design-focused) (SDSI) exam. Each session draws questions proportionally from all 4 official blueprint domains published by Cisco, so the topic mix you see accurately reflects what you'll face on test day.
SDSI Domain Distribution
Risk Events And Requirements
AI Automation And Devsecops
Application Security Design
Secure Infrastructure Design
Every question is written by certified engineers against the 2026 SDSI exam objectives. These are original practice questions — not dumps — so you build real understanding rather than memorising answers.
Both the mock exam and practice test use the same question bank. The difference is in how you use them — and when to use each during your SDSI study plan.
Practice test — for learning
Use the SDSI practice test when you are studying a domain. Answer questions, read every explanation immediately, and build understanding. Do 10–30 questions per domain per session. This is your primary study tool for the first 4 weeks.
Go to practice test →Mock exam — for simulation
Use the SDSI mock exam in the final 1–2 weeks before your test date. Complete a 60 or 120-question session without stopping, manage your time, then review all results at the end. This builds exam-day stamina and surfaces final weak spots.

Sitting the SDSI under real exam conditions is a skill in itself. Candidates who underperform often do so not because of knowledge gaps, but because of poor time management or test anxiety. Use your final mock exam sessions to address both.
The SDSI exam lasts 120 minutes. Do not spend more than 90 seconds on any single question on the first pass. Flag difficult ones and return to them after completing the rest.
On every question, immediately eliminate obviously wrong choices. Even if you are unsure between two options, narrowing to two doubles your odds. Most SDSI distractors contain a subtle error — re-read the scenario constraint before committing to the answer that sounds most familiar.
Cisco writes many SDSI questions as realistic scenarios. Read the final sentence first — it tells you what is being asked. Then re-read the scenario with the question in mind to avoid wasting time on irrelevant details.
The real SDSI is a mental marathon lasting 120 minutes. In the week before your exam, complete at least two full timed mock sessions on separate days to build concentration stamina. If you cannot stay focused for 120 minutes in practice, you will struggle on exam day.

Yes. Courseiva provides free SDSI mock exam questions across all official exam domains. The platform includes timed simulation, per-domain score breakdown, missed-question review, and readiness tracking. No account required — free forever, supported by advertising.
The practice test is optimised for learning: you see explanations after each question immediately. The mock exam is optimised for simulation: you answer all questions under time pressure and review at the end. Use practice tests for studying and mock exams for benchmarking.
Aim for consistent scores above 80% before booking your SDSI exam. Strong mock-exam performance is a reliable indicator of readiness. Cisco passing scores vary by exam version and are not always publicly listed. Check the official Cisco exam page before booking.
Most candidates who pass SDSI on their first attempt complete 3–5 full-length mock exams in the two weeks before their test. This is enough to identify final weak spots, build stamina, and verify readiness without over-stressing or running out of fresh questions.
No — all Courseiva questions are original, written by certified engineers against public Cisco exam blueprints. Exam dumps are memorised real exam questions shared illegally. Using dumps violates your Cisco certification agreement and can result in your certification being revoked. Our questions make you genuinely competent, not just test-day lucky.
Track your mock exam scores, see per-domain analytics, and benchmark readiness across every certification.
