CS0-004 practice examsFinished
CompTIA Cybersecurity Analyst (CySA+) V4
CompTIA CySA+ validates the skills needed to leverage intelligence and threat detection techniques, analyze and interpret data, identify and address vulnerabilities, suggest preventative measures, and effectively respond to and recover from incidents.
What you get
Papers are cut from the bank and weighted like the real exam, and no question appears in two of them. Every wrong answer comes back on later days until you have it right.
What the exam covers
| Security Operations | 34% |
| Vulnerability Management | 26% |
| Incident Response and Management | 24% |
| Reporting and Communication | 16% |
Two sample questions
1. An organization's attack surface management tool discovers an externally accessible API endpoint that is not in the asset inventory. The API returns internal data when queried. What is the FIRST action the analyst should take?
- Add the API endpoint to the vulnerability scanner scope and wait for the next scheduled scan to assess its security posture automatically
- Perform a full penetration test of the discovered API to determine the complete extent of data exposure before reporting findings
- Immediately block the API endpoint at the perimeter firewall and then identify the system owner to assess the exposure and required remediation — correct
- Document the finding in the monthly vulnerability management report for review at the next security governance committee meeting
Why: An unknown externally accessible API exposing internal data is an immediate risk requiring urgent containment. Block access first to stop the exposure, then identify the owner for proper assessment and remediation. Penetration testing delays containment, scheduled scans are too slow, and monthly reporting allows extended exposure.
2. Network traffic paths and firewall rules must change automatically through a central controller. Which technology enables this?
- Manual switch configuration
- Static routing tables
- Static ARP entries on hosts
- Software-defined networking — correct
Why: SDN separates the control plane into a programmable controller that configures network devices centrally.
