CompTIA CySA+ Certification Exam Practice Test
Cybersecurity analysis work involves examining security alerts, endpoint and network evidence, and threat indicators to identify suspicious activity. The available practice questions touch on practical tasks such as checking historical connections, handling potentially malicious files and URLs safely, validating recovery backups, and communicating incident severity to business leaders.
Exam overview
About the CompTIA CySA+ Certification Exam
Effective analysis connects technical observations to defensible response decisions. Analysts correlate endpoint, network, and threat-intelligence data to investigate whether a device contacted a malicious address, while distinguishing actionable alerts from benign administrative activity. Tuning detections requires reducing false positives without suppressing meaningful signals. Incident work also includes safely isolating suspicious content for examination, expressing severity in terms that nontechnical leaders can act on, and confirming that recovery data is suitable before restoring a system. Questions also address security operations practices such as checking endpoint patch status, applying multifactor authentication, and exchanging machine-readable threat information with standards such as STIX. These scenarios exercise evidence selection, risk communication, detection judgment, and recovery validation rather than memorization alone.
Sample Practice Questions
Review a selection from this exam's published US Practice Tests practice bank.
An organization is preparing to restore a system after a destructive malware incident. Which check best helps ensure that the selected backup is suitable for recovery?
Show answer
Correct answer: AA recovery backup should be validated as clean, recent enough for business needs, and usable through restoration testing. Size and recency alone do not establish that a backup is intact or free of compromise.
An analyst needs to communicate incident severity to leaders who are not security specialists. Which approach is most effective?
Show answer
Correct answer: AA concise summary of business impact, scope, and required decisions helps leaders understand the incident and act. Technical evidence can be included as supporting detail for the appropriate audience.
A team wants to check whether an operating system update has been applied consistently across managed endpoints. Which capability is most suitable for identifying devices with missing updates?
Show answer
Correct answer: APatch management reporting inventories update status and can identify endpoints that are missing required fixes. The other capabilities serve unrelated purposes.
An analyst receives a suspicious attachment for examination. Which handling choice best reduces the chance of accidentally executing its contents?
Show answer
Correct answer: AAn isolated analysis environment limits the potential impact of accidental execution and supports controlled examination. Opening the file on a normal workstation or distributing it increases exposure, while renaming does not neutralize its behavior.
An organization requires employees to sign in with a password and a time-based code from an authenticator application. What security measure does this illustrate?
Show answer
Correct answer: AA password is a knowledge factor, while a code generated by an authenticator application is generally a possession factor. Requiring both is multifactor authentication.
A team is tuning an alert that fires frequently on approved administrative activity. What is the best way to reduce false positives while retaining useful detection coverage?
Show answer
Correct answer: BNarrowly scoped, evidence-based tuning can suppress known benign activity while preserving detection of other suspicious cases. The team should test changes against both benign and known-malicious data where available.
A security analyst needs to determine whether an endpoint has been communicating with a known malicious IP address. Which data source is most directly useful for checking past network connections?
Show answer
Correct answer: AEndpoint network connection logs can show remote addresses and connection times, helping the analyst verify whether the endpoint contacted the indicator. Other listed records do not ordinarily document network connections.

Preparation tips
- For network-investigation scenarios, distinguish historical connection evidence—such as firewall, proxy, DNS, or flow records—from current threat-intelligence lookups.
- When considering malware or suspicious URLs, prioritize isolated analysis environments and handling steps that prevent execution or exposure on a production workstation.
- Practice explaining incident severity through business impact, affected services, and urgency, not only technical indicators.
- Compare alert-tuning choices by asking whether they reduce known benign activity while preserving detection of suspicious behavior.
- For recovery questions, distinguish the existence of a backup from evidence that it is clean, usable, and successfully tested for restoration.
