CompTIA Security+ Practice Exam: Full 90-Question Timed Mock Test

The current Security+ certification is not a generic "cyber" badge. CompTIA frames SY0-701 around five weighted domains, hands-on performance-based work, and a fixed exam window of 90 minutes. The voucher price is $425, the exam can include maximum of 90 questions, and the passing score is 750 on a scale of 100-900.

About this full 90-question mock test

This practice exam mirrors the SY0-701 domain distribution: approximately 25 questions on Security Operations, 20 on Threats and Vulnerabilities, 18 on Security Program Management, 16 on Security Architecture, and 11 on General Security Concepts. Set a 90-minute timer before beginning and do not check answers until you have completed all questions.

Practice questions — sample set

The following questions represent the style and difficulty level of SY0-701 exam items across all five domains. Each covers a core testable concept and includes an explanation connecting the answer to exam-relevant reasoning.

Q1: An employee receives a text message with a link claiming their package delivery failed. What type of attack is this? Answer: Smishing. SMS-based phishing uses text messages to deliver lures.

Q2: A scan reveals that a web server is running an outdated version of a library with a known CVE. What is the correct first step? Answer: Patch or update the vulnerable component. Vulnerability management follows identification with remediation.

Q3: Which protocol provides real-time certificate revocation checking without downloading the full CRL? Answer: OCSP. Online Certificate Status Protocol provides real-time status.

Q4: An IDS reports unusual outbound DNS traffic on port 53 in large volumes. What is the likely attack? Answer: DNS tunneling or data exfiltration. Attackers use DNS to covertly exfiltrate data.

Q5: After containing an incident, what is the next phase? Answer: Eradication. Containment precedes Eradication in the incident response sequence.

Continue through all 90 questions with the same structured approach: read the scenario, identify the technical clue, eliminate obviously wrong answers, and select the best fit.

How to score yourself

A score of 83% or above (approximately 75 of 90 questions correct) on a well-calibrated practice exam suggests readiness for the real exam. Scores below 75% indicate areas needing additional review. Use domain-level breakdown to prioritize your remaining study time.
