CompTIA CySA+ (CS0-004) Practice Exams

Aligned to the official CompTIA Cybersecurity Analyst (CySA+) (CS0-004) exam objectives (V4).

Prepare to pass the CompTIA CySA+ (CS0-004) certification exam with confidence. This comprehensive practice exam course includes 750 original, exam-style questions spread across 6 full-length practice tests, carefully weighted to match the official CS0-004 exam domains: Security Operations (34%), Vulnerability Management (26%), Incident Response and Management (24%), and Reporting and Communication (16%). The course also includes 10 performance-based questions (PBQs) in print format — log analysis, vulnerability-scan triage, incident-response ordering, cloud assessment findings, phishing header analysis, evidence handling, and SOC metrics — so the hands-on side of the real exam will not surprise you.

Every question comes with a detailed explanation of why the correct answer is right and why each wrong answer is wrong. Questions are scenario-first, built around the work of a real security operations centre: reading logs and packet captures, triaging SIEM alerts, prioritising vulnerabilities with CVSS and asset context, running an incident through all seven response phases, and reporting findings to technical and executive audiences.

This course gives dedicated coverage to every tool named in the official CS0-004 objectives — Nmap, Wireshark, tcpdump, Zeek, Snort, Suricata, YARA and Sigma; Nessus, Nuclei and OpenVAS; Burp Suite, OWASP ZAP and Nikto; Metasploit, Maltego and Recon-ng; ScoutSuite, Prowler, Trivy and Checkov; and the breach attack simulation tools Atomic Red Team and Caldera — including the tool-vs-tool distinctions the exam loves to test.

Whether you are a SOC analyst formalising your skills, a Security+ holder stepping up, or an IT professional moving into a cybersecurity role, these practice exams will find your weak areas and build the confidence you need on exam day. Each practice test simulates the real exam under timed conditions with an 80% passing score requirement.

A companion study guide is free to read on the CertCrack website, with illustrated walkthroughs for every procedure — drawn for the book, never fake screenshots. Track your progress across all six tests, focus your remaining study on weaker domains, and walk into your CS0-004 exam fully prepared.
