1500 Questions | CompTIA CySA+ Certification 2026

free sc 200 microsoft security operations analyst exam prep 2026 course 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.

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:

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?

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:

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?

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:

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.
