1500 Questions | CompTIA CySA+ Certification 2026

Detailed Exam Domain Coverage

To earn your CompTIA CySA+ certification, you must demonstrate a high level of proficiency in security analytics and incident response. This practice test suite is meticulously mapped to the official exam domains:

• Security and Risk Management (24%): Analyzing risks to systems, conducting deep vulnerability scans, and implementing enterprise-wide risk strategies.

• Security Operations and Monitoring (22%): Implementing robust security controls, monitoring complex event logs, and managing real-time incident responses.

• Threat and Vulnerability Management (22%): Identifying sophisticated vulnerabilities, understanding penetration testing results, and executing mitigation plans.

• Data Security (21%): Mastering data encryption standards, configuring granular access controls, and ensuring continuous data integrity.

• Container and Server Security (11%): Hardening server settings and implementing secure containerization practices in modern cloud environments.

Course Description

I designed this course to be the final step in your preparation for the CompTIA CySA+ (CS0-003) exam. Moving beyond theoretical knowledge, these practice tests challenge your ability to analyze logs, identify threats, and recommend technical solutions—just as you will be required to do during the actual 165-minute examination.

With a massive bank of 1,500 original practice questions, I provide the depth and variety needed to ensure no surprise topics catch you off guard. Every question includes a comprehensive breakdown of why the correct answer is right and why the distractors are wrong, helping you refine your analytical "SOC mindset."

Sample Practice Questions

• Question 1: A cybersecurity analyst is reviewing a vulnerability scan report that identifies a critical "Buffer Overflow" vulnerability in a legacy web application. Which of the following is the BEST immediate mitigation strategy?

  • A. Perform a full penetration test on the server.

  • B. Implement an Input Validation filter at the application layer.

  • C. Update the server's BIOS to the latest version.

  • D. Disable the Windows Firewall on the application server.

  • E. Change the administrative password for the database.

  • F. Re-run the scan with lower sensitivity settings.

  • Correct Answer: B

  • Explanation:

    • B (Correct): Buffer overflows often occur due to poor handling of user input. Validating input ensures that the data sent to the application fits expected parameters, preventing the memory overwrite.

    • A (Incorrect): While useful for discovery, a pen test is not a mitigation strategy; it is a testing method.

    • C (Incorrect): BIOS updates rarely patch application-level buffer overflow vulnerabilities.

    • D (Incorrect): Disabling a firewall would decrease security and has no impact on fixing an application flaw.

    • E (Incorrect): Changing passwords does not address the underlying code vulnerability causing the overflow.

    • F (Incorrect): Lowering sensitivity only hides the problem; it does not mitigate the risk.

• Question 2: During an incident response, an analyst observes multiple failed SSH login attempts from an external IP followed by a single successful login. What is the most likely threat being observed?

  • A. SQL Injection.

  • B. Cross-Site Scripting (XSS).

  • C. Brute-Force Attack.

  • D. Denial of Service (DoS).

  • E. Man-in-the-Middle (MitM).

  • F. Social Engineering.

  • Correct Answer: C

  • Explanation:

    • C (Correct): Multiple failures followed by a success is a textbook indicator of a brute-force or dictionary attack where the attacker finally guessed the correct credentials.

    • A (Incorrect): SQL Injection targets database queries, not SSH login interfaces.

    • B (Incorrect): XSS involves injecting scripts into web pages for other users to execute.

    • D (Incorrect): DoS attacks aim to crash a service, not gain authenticated access.

    • E (Incorrect): MitM involves intercepting active communication; it doesn't typically start with a series of failed login attempts.

    • F (Incorrect): While a password could be gained via social engineering, the pattern of "multiple failures" points toward an automated technical attack.

• Question 3: Which of the following commands would a CySA+ analyst use on a Linux system to view active network connections and the associated process IDs?

  • A. ls -la

  • B. grep "error" /var/log/syslog

  • C. netstat -p

  • D. chmod 777 /etc/shadow

  • E. df -h

  • F. traceroute 8.8.8.8

  • Correct Answer: C

  • Explanation:

    • C (Correct): The netstat command (specifically with the -p flag) displays active network connections and identifies which program/process is using the socket.

    • A (Incorrect): ls is used to list files in a directory.

    • B (Incorrect): This command searches log files for specific text but doesn't show active connections.

    • D (Incorrect): This changes file permissions and is a significant security risk; it doesn't show network data.

    • E (Incorrect): df shows disk space usage.

    • F (Incorrect): traceroute shows the path packets take to a destination but not local process-to-connection mapping.
