50 Free CompTIA Security+ Practice Questions (SY0-701) With Answer Explanations

Security+ is broad, vendor-neutral, and tied to real exam constraints rather than vague cybersecurity marketing. The current CompTIA exam is SY0-701. It costs $425, allows maximum of 90 questions in 90 minutes, and requires 750 on a scale of 100-900 to pass. Those numbers shape how you should interpret Security+ practice questions SY0-701, because they tell you how much content you must cover and how quickly you must apply it.

What does a good Security+ practice set need to do?

A useful practice set for Security+ has to mirror the exam's breadth and timing. CompTIA's current exam is SY0-701, with a maximum of 90 questions in 90 minutes, a passing score of 750 on a 100–900 scale, and PBQs appearing near the front of the exam experience for many candidates. That means a practice set should not only ask definitions. It should force you to identify the best control, the next incident-response step, the relevant port, the likely attack path, or the weak point in a trust chain.

CompTIA's official Security+ page lists these five SY0-701 domains and weights: General Security Concepts — 12%; Threats, Vulnerabilities, and Mitigations — 22%; Security Architecture — 18%; Security Operations — 28%; Security Program Management and Oversight — 20%. Those weights matter. Security Operations is 28%, so hardening, monitoring, vulnerability management, IAM operations, and incident response get more exam space than any other area. Threats, Vulnerabilities, and Mitigations follows at 22%, then Security Program Management and Oversight at 20%, Security Architecture at 18%, and General Security Concepts at 12%.

CompTIA also places performance-based items prominently in the exam experience. CompTIA's own Security+ exam article says most PBQs appear at the beginning of the exam, before you see the bulk of the multiple-choice items. That detail changes test strategy because the hardest simulation-style work often lands while the clock still shows a full 90 minutes. Security+ renewal is also specific: CompTIA requires 50 CEUs in a three-year cycle, or another approved renewal path, and publishes a three-year CE fee total of $150 for Security+.

Questions 16 through 50 continue drilling key SY0-701 concepts across all five domains: Security Operations, Threats and Vulnerabilities, Security Architecture, Security Program Management, and General Security Concepts. Topics include incident response phases, cryptographic algorithms, PKI trust chains, network segmentation, wireless security, IAM controls, vulnerability management, and governance frameworks.

How should you score yourself after a Security+ practice round?

Look for patterns, not a raw percentage alone. Missing one item about port 3389 is a memory gap. Missing five questions that all involve control selection, least privilege, or containment order points to a domain weakness. If you consistently lose time on scenario questions, work on reading the last sentence first, then scanning for the technical clue that narrows the answer set. If you are losing points on cryptography, map each term to its function: encryption, hashing, signing, exchange, or trust validation.

Our CompTIA Security+ study guide covers all five SY0-701 domains with domain-weighted practice questions, a performance-based question walkthrough, a ports and protocols cheat sheet, and a 6-week study schedule built around the exam's actual content weighting.
