Splunk Certified Cybersecurity Defense Engineer Sample Questions (Q100-Q105):

NEW QUESTION # 100
Which phase of the incident response lifecycle would cause the least amount of friction when replacing manual steps with automation?

A. Triage
B. Remediation
C. Containment
D. Rendering a verdict

Answer: A

Explanation:
Triage involves repetitive, data-gathering, and enrichment steps (e.g., indicator lookups, context collection) that can be automated with minimal risk. This phase typically introduces the least friction when shifting from manual work to automation.

NEW QUESTION # 101
Which features of Splunk are crucial for tuning correlation searches? (Choose three)

A. Reviewing notable event outcomes
B. Disabling field extractions
C. Enabling event sampling
D. Optimizing search queries
E. Using thresholds and conditions

Answer: A,D,E

Explanation:
Correlation searches are a key component of Splunk Enterprise Security (ES) that help detect and alert on security threats by analyzing machine data across various sources. Proper tuning of these searches is essential to reduce false positives, improve performance, and enhance the accuracy of security detections in a Security Operations Center (SOC).
Crucial Features for Tuning Correlation Searches
1. Using Thresholds and Conditions (A)
Thresholds help control the sensitivity of correlation searches by defining when a condition is met.
Setting appropriate conditions ensures that only relevant events trigger notable events or alerts, reducing noise.
Example:
Instead of alerting on any failed login attempt, a threshold of 5 failed logins within 10 minutes can be set to identify actual brute-force attempts.
2. Reviewing Notable Event Outcomes (B)
Notable events are generated by correlation searches, and reviewing them is critical for fine- tuning. Analysts in the SOC should frequently review false positives, duplicates, and low-priority alerts to refine rules.
Example:
If a correlation search is generating excessive alerts for normal user activity, analysts can modify it to exclude known safe behaviors.
3. Optimizing Search Queries (E)
Efficient Splunk Search Processing Language (SPL) queries are crucial to improving search performance.
Best practices include:
Using index-time fields instead of extracting fields at search time.
Avoiding wildcards and unnecessary joins in searches.
Using tstats instead of regular searches to improve efficiency.
Example:
Using:
| tstats count where index=firewall by src_ip
instead of:
index=firewall | stats count by src_ip
can significantly improve performance.

NEW QUESTION # 102
What are key benefits of using summary indexing in Splunk? (Choose two)

A. Reduces storage space required for raw data
B. Provides automatic field extraction during indexing
C. Increases data retention period
D. Improves search performance on aggregated data

Answer: C,D

Explanation:
Summary indexing in Splunk improves search efficiency by storing pre-aggregated data, reducing the need to process large datasets repeatedly.
Key Benefits of Summary Indexing:
Improves Search Performance on Aggregated Data (B)
Reduces query execution time by storing pre-calculated results.
Helps SOC teams analyze trends without running resource-intensive searches.
Increases Data Retention Period (D)
Raw logs may have short retention periods, but summary indexes can store key insights for longer.
Useful for historical trend analysis and compliance reporting.

NEW QUESTION # 103
When creating detections, which of the following sequences would result in the most performant SPL query?

A. Define base query, minimize data, combine/summarize data, execute calculations, format the data
B. Define base query, combine/summarize data, minimize data, execute calculations, format the data
C. Define base query, minimize data, combine/summarize data, format the data, execute calculations
D. Define base query, minimize data, format the data, combine/summarize data, execute calculations

Answer: A

Explanation:
The most performant SPL query sequence is:
Define base query → Minimize data → Combine/Summarize data → Execute calculations → Format the data.
Minimizing the data early (using filters, time constraints, and field limitations) reduces the dataset before expensive operations like summarization or calculations, resulting in optimal performance.

NEW QUESTION # 104
Which report type is most suitable for monitoring the success of a phishing campaign detection program?

A. SLA compliance reports
B. Weekly incident trend reports
C. Risk score-based summary reports
D. Real-time notable event dashboards

Answer: D

Explanation:
Why Use Real-Time Notable Event Dashboards for Phishing Detection?
Phishing campaigns require real-time monitoring to detect threats as they emerge and respond quickly.
#Why "Real-Time Notable Event Dashboards" is the Best Choice? (Answer B)#Shows live security alerts for phishing detections.#Enables SOC analysts to take immediate action (e.g., blocking malicious domains, disabling compromised accounts).#Uses correlation searches in Splunk Enterprise Security (ES) to detect phishing indicators.
#Example in Splunk:#Scenario: A company runs a phishing awareness campaign.#Real-time dashboards track:
How many employees clicked on phishing links.
How many users reported phishing emails.
Any suspicious activity (e.g., account takeovers).
Why Not the Other Options?
#A. Weekly incident trend reports - Helpful for analysis but not fast enough for phishing detection.#C. Risk score-based summary reports - Risk scores are useful but not designed for real-time phishing detection.#D.
SLA compliance reports - SLA reports measure performance but don't help actively detect phishing attacks.
