Cisco Designing Cisco Security Infrastructure is an official exam run by Cisco under exam code 300-745. Passing it awards the CCNP Security, Cisco Certified Specialist – Designing Cisco Security Infrastructure certification, which sits at the Professional tier. It also counts toward related credentials such as Cisco Certified Specialist – Designing Cisco Security Infrastructure. Certified professionals remain in shorter supply than the market wants, which is precisely why this exam keeps showing up in conversations about better roles and better pay.

The Cisco Designing Cisco Security Infrastructure exam gives you 90 minutes to work through 55–65 questions. That is a tight ratio, and it punishes candidates who get emotionally attached to any single item. The fix is mechanical: answer what you know, flag what you do not, and keep moving. A few full-length timed runs in the Actual4Exams test engine, with its randomized question order, will calibrate your pace far better than untimed reading ever could.

The official fee for Cisco Designing Cisco Security Infrastructure is USD 300, and Pass/Fail (scaled score 750–850 / 1000) is what passing takes. The uncomfortable part: retakes cost the full USD 300 again, which makes preparation the cheapest line item in this whole project. Before booking, put yourself through repeated scored sessions with the Actual4Exams practice tests and compare results over time; a stable margin above the passing line, not a single lucky run, is when you are ready.

No formal prerequisites; recommended knowledge of security architecture, threat modeling, and secure system design

It is. Actual4Exams publishes a free PDF demo of the Cisco Designing Cisco Security Infrastructure material, so the product can prove itself before you pay. Your purchase then comes with 365 days of free updates, and once that period ends, extending the update service costs 50% of the regular price. The test engine software itself is verified malware-free and safe to install.

Actual4Exams stands behind the product with a 100% money-back guarantee under defined conditions. If you take the Cisco Designing Cisco Security Infrastructure exam within 60 days of purchase and fail, you qualify for a full refund, provided the exam corresponds to your product. Sitting the exam within 3 days of purchase does not qualify, and neither do unused downloads, free materials, or expired orders; the candidate name must match the payer name. Submit a scanned enrollment slip and the official Score Report PDF within 2 days of the exam, and claims are resolved within 7 days. You may also choose an exchange instead of a refund: two other exam products of equal value, free, with the update service on your original purchase retained.

Delivery takes about a minute. Files unlock for instant download at payment and are emailed to you automatically; if 2 hours pass with nothing received, check spam and contact customer service. There is no installation limit, so the test engine can live on every device you own, phone included.
