Splunk Defense Analyst Sample Questions & Practice Test

Splunk Cybersecurity Defense Analyst is a security-operations route for candidates who triage alerts, interpret detections, investigate notable events, correlate evidence, and decide what to escalate.

Use this page to try original IT Mastery sample questions on SOC decisions. They are not official Splunk exam questions.

What these questions test

• reading alert and notable-event evidence before deciding severity
• correlating identity, endpoint, network, cloud, and application data
• using risk, asset, and identity context to prioritize investigation
• documenting next steps without assuming every detection is a confirmed incident

Sample Exam Questions

Question 1

Topic: triage

A notable event shows impossible travel, failed MFA, and a successful login from a new country. What should the analyst do first?

• A. Close it because MFA was involved
• B. Treat it as suspicious, preserve evidence, review user context, and check related activity
• C. Delete the notable event
• D. Disable all identity detections

Best answer: B

Explanation: Multiple identity signals justify investigation. The analyst should preserve evidence and validate context before deciding response.

Question 2

Topic: risk context

Why might the same detection receive higher priority for one host than another?

• A. All detections must be treated identically
• B. Hostnames with more letters are always critical
• C. The host’s business criticality, exposed data, user role, and risk history can change impact
• D. Risk context is never useful

Best answer: C

Explanation: Asset and identity context helps prioritize limited analyst time. Critical assets and privileged users increase potential impact.

Question 3

Topic: correlation

An endpoint alert and proxy alert involve the same user within five minutes. What is the best investigation step?

• A. Delete proxy data
• B. Escalate without checking context
• C. Ignore one alert because two tools cannot both matter
• D. Review whether the alerts share a timeline, host, user, destination, and behavior chain

Best answer: D

Explanation: Correlation connects signals into a possible attack sequence. Shared entities and timing can increase confidence.

Question 4

Topic: threat hunting

A hunt hypothesis states, “Attackers may use PowerShell to download payloads from rare domains.” What should the analyst search for?

• A. PowerShell execution, command-line indicators, network destinations, domain rarity, and related host behavior
• B. Only dashboard titles
• C. Every successful login
• D. Printer errors

Best answer: A

Explanation: A hunt should translate the hypothesis into observable data. Process, command-line, network, and rarity signals are relevant.

Question 5

Topic: false positives

A detection fires every time an approved vulnerability scanner runs. What should the analyst recommend?

• A. Ignore every future alert from that subnet
• B. Tune the detection with scanner identity, schedule, and expected behavior while preserving alerts for unexpected sources
• C. Disable every exploit detection
• D. Delete all scanner logs

Best answer: B

Explanation: Tuning should reduce known noise without hiding real attacks. Source, schedule, and expected behavior make the exception safer.

Question 6

Topic: notable event review

Which field is most useful when deciding who should handle a notable event?

• A. Browser window size
• B. The event’s row number only
• C. Owner, urgency, asset or identity context, detection type, and affected system
• D. Dashboard color

Best answer: C

Explanation: Routing and prioritization depend on ownership, urgency, affected assets, and the detection context.

Question 7

Topic: enrichment

What is the purpose of enriching an IP address with reputation and ownership data?

• A. It proves the event is malicious in every case
• B. It deletes the original event
• C. It replaces all analyst judgment
• D. It adds context that can support prioritization and investigation decisions

Best answer: D

Explanation: Enrichment adds context, not certainty. Analysts still need to evaluate evidence and environment-specific context.

Question 8

Topic: escalation

When should an analyst escalate from alert review to incident response?

• A. When evidence suggests real compromise, material impact, or urgent containment need under the response process
• B. Never, because alerts are always false positives
• C. Whenever a dashboard refreshes
• D. Only after a monthly meeting

Best answer: A

Explanation: Escalation should be evidence-based and tied to impact, confidence, and containment needs.

Question 9

Topic: MITRE mapping

Why map detections to attack techniques?

• A. To remove the need for logs
• B. To replace asset inventory
• C. To understand coverage, communicate attacker behavior, and identify gaps across tactics and techniques
• D. To prove every event is a breach

Best answer: C

Explanation: Technique mapping helps organize detection coverage and analysis. It does not prove that an attack occurred by itself.

Question 10

Topic: investigation timeline

Why build a timeline during an investigation?

• A. It hides analyst decisions
• B. It replaces evidence collection
• C. It makes all alerts critical
• D. It helps show sequence, scope, first observed activity, affected entities, and response actions

Best answer: D

Explanation: Timelines help analysts understand what happened and when. They support scoping, handoff, and reporting.

Question 11

Topic: suppression

A suppression rule is requested for a noisy detection. What should be verified before approving it?

• A. Scope, duration, business justification, expected behavior, owner, and residual risk
• B. Whether logs can be disabled
• C. Whether the detection name is long
• D. Whether all alerts can be hidden forever

Best answer: A

Explanation: Suppression should be controlled and reviewable. Broad or permanent suppression can hide real threats.

Question 12

Topic: analyst notes

What makes investigation notes useful?

• A. Personal opinions with no evidence
• B. Clear evidence, reasoning, actions taken, unresolved questions, and recommended next steps
• C. Deleting notes after closure
• D. Only copying the alert title

Best answer: B

Explanation: Good notes support handoff, review, and defensible decisions. They should explain both evidence and reasoning.
