SPLK-5002 Splunk Certified Cybersecurity Defense Engineer Free Practice Exam Questions (2025 Updated)

In Splunk Enterprise Security (ES), notable events are generated by correlation searches, which are predefined searches designed to detect security incidents by analyzing logs and alerts from multiple data sources. Adding additional context to these notable events enhances their value for analysts and improves the efficiency of incident response.

To incorporate additional context, you can:

Use lookup tables to enrich data with information such as asset details, threat intelligence, and user identity.

Leverage KV Store or external enrichment sources like CMDB (Configuration Management Database) and identity management solutions.

Apply Splunk macros orevalcommands to transform and enhance event data dynamically.

Use Adaptive Response Actions in Splunk ES to pull additional information into a notable event.

The correct answer is A. By adding enriched fields during search execution, because enrichment occurs dynamically during search execution, ensuring that additional fields (such as geolocation, asset owner, and risk score) are included in the notable event.

Using Lookups for Data Enrichment

Monitoring indexing performance in Splunk is crucial for ensuring efficient data ingestion, search performance, and resource utilization.

Methods to Monitor Indexing Performance Effectively:

Use the Monitoring Console (A)

Provides real-time visibility into indexing performance.

Displays resource utilization, indexing rate, queue health, and disk usage.

Track Indexer Queue Size and Throughput (D)

Monitoring queue sizes prevents indexing bottlenecks.

Ensures data is processed efficiently without delays.

The Splunk REST API allows programmatic access to Splunk’s features, helping automate security workflows in a Security Operations Center (SOC).

Key REST API Actions for Automation:

POST for creating new data entries (A)

Used to send logs, alerts, or notable events to Splunk.

Essential for integrating external security tools with Splunk.

GET for retrieving search results (C)

Fetches logs, alerts, and notable event details programmatically.

Helps automate security monitoring and incident response.

The GET method in the Splunk REST API is used to retrieve data from a Splunk index. It allows users and automated scripts to fetch logs, alerts, or query results programmatically.

Key Points About GET in Splunk API:

Used for searching and retrieving logs from indexes.

Can be used to get search results, job status, and Splunk configuration details.

Common API endpoints include:

/services/search/jobs/{search_id}/results– Retrieves results of a completed search.

/services/search/jobs/export– Exports search results in real-time.

If there is a delay in data being indexed from a remote location, even though the Universal Forwarder (UF) is correctly configured, the issue is likely a queue blockage or network latency.

Steps to Diagnose and Fix Forwarder Delays:

Check Forwarder Logs (splunkd.log) for Queue Issues (A)

Look for messages likeTcpOutAutoLoadBalancedorQueue is full.

If queues are full, events are stuck at the forwarder and not reaching the indexer.

Monitor Forwarder Health Usingmetrics.log

Useindex=_internal source=*metrics.log* group=queueto check queue performance.
