Cisco 300-745 — Frequently Asked Questions (FAQs)
SECTION A: Cisco 300-745 Certification Overview
Q1. What is the Cisco 300-745 exam?
The Cisco 300-745 exam, Designing Cisco Security Infrastructure (SDSI v1.0), is a 90-minute Specialist-level exam about planning security architecture rather than operating a single product. It counts as a concentration exam for CCNP Security. Cisco divides its topics into four weighted domains, and Secure Infrastructure is one of the two largest at 30%.
Q2. Who should take the Cisco 300-745 exam?
The Cisco 300-745 exam suits security architects and senior engineers who choose controls for whole environments. Cisco publishes no separate target-candidate statement, so this reading comes from the exam topics; the CCNP Security page lists no prerequisite for 300-745. Its Secure Infrastructure objectives ask you to select firewall architectures and VPN and tunneling options from business and technical requirements, so people who already shape designs, not only configure devices, have the most natural background.
Q3. What skills does the Cisco 300-745 exam measure?
Cisco 300-745 measures whether you can design security infrastructure across four domains: Secure Infrastructure (30%), Applications (25%), Risk, Events, and Requirements (30%), and Artificial Intelligence, Automation, and DevSecOps (15%). You select protections for endpoints, identity and email, choose VPN, tunneling and firewall architectures, and secure management and control planes. Further objectives cover microsegmentation for cloud-native workloads, policy for generative AI and quantum computing, modifying a design after an incident, frameworks such as MITRE CAPEC, NIST SP 800-37 and SAFE, matching compliance documents to scenarios, and DevSecOps pipeline steps.

Q4. How many questions are on the Cisco 300-745 exam?
Cisco does not publish a fixed question count for the 300-745 exam, and its exam-topics page explains that with performance-based testing the number of questions may vary. Plan around the 90-minute limit instead of a number. With 16 objectives spread over four domains, a steady pace matters more than racing through early items, so keep time in reserve for requirement-heavy questions.
Q5. How long is the Cisco 300-745 exam?
Cisco gives you 90 minutes to complete the 300-745 exam. That window covers every item, and many objectives ask you to choose a design from business and technical requirements, so rehearse working through requirement-heavy questions under a clock. Check the official exam page for the current duration shortly before you book.
Q6. What types of questions appear on the Cisco 300-745 exam?
The Cisco 300-745 exam uses Cisco’s performance-based testing, which the exam-topics page says is meant to replicate a true lab environment as closely as possible. Cisco does not list the individual item formats for this exam. The objective verbs give a useful hint: each one begins with select, modify, describe or match, as in matching a regulatory or industry compliance document to a scenario under Risk, Events, and Requirements, so expect to judge designs against stated requirements.
Q7. Can I take the Cisco 300-745 exam online or at a test center?
Cisco’s 300-745 exam page does not say whether the exam is delivered online, at a test center or both, so confirm the available options at the point of booking. Whatever delivery option Cisco offers, the exam is in English and lasts 90 minutes. Read the testing rules shown at booking before exam day.
Q8. What score do I need to pass the Cisco 300-745 exam?
Cisco does not publish a passing score for the 300-745 exam. Without a known cut score, aim for consistent results in every domain, including Artificial Intelligence, Automation, and DevSecOps, which carries only 15% but is easy to neglect. Look at the official exam page in case Cisco adds scoring details later.
SECTION C: Cisco 300-745 Difficulty & Readiness
Q9. How difficult is the Cisco 300-745 exam?
Designing Cisco Security Infrastructure (300-745) is hard for candidates whose experience is mostly device configuration, because it asks for design judgement across a whole environment. Secure Infrastructure, at 30%, expects you to pick between traditional, next-generation, web application, distributed, eBPF and host-based firewalls given requirements, and to choose among SD-WAN, IPsec, MPLS, GRE and DMVPN. Risk, Events, and Requirements, also 30%, adds compliance and post-incident redesign, which reward real architecture work.
Q10. What makes the Cisco 300-745 exam challenging?
The Cisco 300-745 exam is challenging because most objectives have no single right technology; the right choice depends on the requirements in the question. Secure Infrastructure covers hybrid workers, IoT, SaaS and multi-cloud applications, Applications adds SSL decryption, DLP and serverless microsegmentation, and Risk, Events, and Requirements brings in SOC tooling, MITRE CAPEC and NIST SP 800-37. Artificial Intelligence, Automation, and DevSecOps then asks about SOAR, Infrastructure as Code and container scanning.
SECTION D: Cisco 300-745 Preparation Strategy
Q11. How should I start preparing for the Cisco 300-745 exam?
Start preparing for the Cisco 300-745 exam by downloading the official SDSI exam topics and rating your confidence on each of the 16 objectives. Next, work through the Cisco U. learning path for the exam to get a structured overview. Practise turning written requirements into designs early, since Secure Infrastructure objectives such as modifying the architecture for hybrid workers, IoT and SaaS assume you have done this in real work or realistic exercises.
Q12. Which skills should I focus on to pass the Cisco 300-745 exam?
Put most effort into the two 30% domains of the Cisco 300-745 exam: Secure Infrastructure and Risk, Events, and Requirements. That means firewall, VPN and tunneling selection, control-plane protection, risk mitigation, incident-driven redesign, frameworks and compliance mapping. Applications, at 25%, comes next, with SSL offloading and decryption, DLP and microsegmentation for containers and serverless designs. Finish with Artificial Intelligence, Automation, and DevSecOps at 15%.
Q13. How long should I prepare for the Cisco 300-745 exam?
Preparation time for the Cisco 300-745 exam depends mostly on how much architecture work you already do. Someone who regularly designs firewall placement, remote access and cloud segmentation may need only targeted study on frameworks such as SAFE and NIST SP 800-37 or on the Artificial Intelligence, Automation, and DevSecOps domain. Someone moving from operations into design should allow considerably longer. A first pass through the Cisco U. learning path for SDSI shows quickly where the gaps are.
Q14. How should I use practice exams to prepare for the Cisco 300-745 exam?
Begin with a short practice set for the Cisco 300-745 exam early on and tag each mistake with its objective number, such as 3.3 for modifying a design after an incident. Study the reasoning behind every missed design choice, sketch an alternative design yourself, then retest on new questions. Near exam day, take a full timed set within 90 minutes and check that your results in Artificial Intelligence, Automation, and DevSecOps (15%) keep pace with the larger domains.
SECTION E: Cisco 300-745 Practice Exams & Preparation Tools
Q15. Do practice tests help when preparing for the Cisco 300-745 exam?
Yes, practice tests help with the Cisco 300-745 exam, mainly by showing which of the four domains is weakest and by training you to make design decisions quickly. They are most useful when every question is original and mapped to an official objective, so that a wrong answer on, for example, choosing between DMVPN and SD-WAN points straight back to objective 1.3 in Secure Infrastructure. Treat scores as a guide to what to study next.
Q16. Should I take practice exams or read study guides to prepare for the Cisco 300-745 exam?
Do both for the Cisco 300-745 exam, because its objectives mix knowledge you can read and judgement you have to practise. Reading works well for the describe objectives, such as how the SOC uses incident response tools or the role of AI in securing network infrastructure. Practice questions suit the select and modify objectives, where you must pick a design for a requirement. Design exercises help most with the VPN and firewall architecture choices in Secure Infrastructure.
Q17. What should I look for in study resources for the Cisco 300-745 exam?
Good study resources for the Cisco 300-745 exam map directly to the current SDSI v1.0 exam topics and explain why one design beats another for a given requirement. Check for coverage of the newer areas, such as design policy for generative AI and quantum computing under Applications, and eBPF among the firewall options, since general security material may not cover them. Compare any resource with Cisco’s published topics before relying on it.
SECTION F: Cisco 300-745 Career & Certification Value
Q18. Is the credential earned by passing the Cisco 300-745 exam worth it?
Yes, the credential earned by passing the Cisco 300-745 exam is worth it for security professionals who design infrastructure, because the exam is built around choosing architectures, mitigating risk and adapting designs after incidents. It also counts toward CCNP Security as a concentration exam. It is less useful to someone whose role never involves design decisions, and it has to be recertified every 3 years.
Q19. Does the credential earned by passing the Cisco 300-745 exam expire?
Yes, a certification earned with the Cisco 300-745 exam is valid for 3 years and then needs recertifying. For CCNP Security, which this exam counts toward, Cisco accepts passing a qualifying exam again, earning a higher-level certification, or collecting 80 Continuing Education (CE) credits. If you renew by exam, study the exam topics in force at that time, since Cisco can revise its exam topics between versions.
Q20. How does the Cisco 300-745 exam relate to other Cisco exams and credentials?
The Cisco 300-745 exam is a CCNP Security concentration exam, and passing it on its own earns a Specialist-level Cisco credential. Its objectives centre on design: choosing architectures, frameworks and compliance responses across infrastructure, applications and DevSecOps rather than implementing one product. The official CCNP Security certification page shows how the core and concentration exams combine.
Ready to move from reading to practice? The fastest way to turn this overview into real exam readiness is deliberate, timed practice: work through structured Cisco 300-745 practice tests that mirror the real exam’s format and domain weighting, then use your results to see exactly where you stand. Track your score by domain rather than by overall percentage, revisit every question you miss — including the ones you only guessed correctly — and keep practising a topic until you can answer it confidently without hesitation. Repeating that cycle in the weeks before test day is what builds the speed, accuracy, and confidence the Cisco 300-745 exam rewards.
