SPLK-2003 Exam Overview

Although exam details may evolve over time, candidates can generally expect questions covering:

The exam tests both conceptual understanding and practical implementation knowledge.

Key Topics You Must Master

Let's break down the most important areas of study.

1. Playbook Development

Playbooks form the foundation of Splunk SOAR automation.

You should understand:

• Playbook architecture

• Action blocks

• Decision blocks

• Filtering mechanisms

• Playbook variables

• Sub-playbooks

• Triggering mechanisms

A large portion of your daily work as a SOAR developer revolves around playbooks, making this one of the highest-priority exam domains.

2. Python Fundamentals

Many candidates underestimate the importance of Python.

You don't need to be a senior software engineer, but you should be comfortable with:

• Functions

• Variables

• Loops

• Dictionaries

• Lists

• JSON processing

• Error handling

Custom functions and advanced automation often rely heavily on Python scripting.

3. REST API Integration

Modern security automation depends on APIs.

You should know how to:

• Authenticate API requests

• Send GET and POST requests

• Parse JSON responses

• Handle API errors

• Work with headers and tokens

Most third-party integrations communicate through REST APIs.

4. Containers and Artifacts

Understanding the data structure within Splunk SOAR is essential.

Focus on:

• Containers

• Artifacts

• Notes

• Evidence

• Action results

Many exam questions test whether you know where information is stored and how workflows access that data.

5. App Development and Customization

A strong developer should understand how applications interact with Splunk SOAR.

Study:

• App configuration

• Asset management

• Connectors

• Action definitions

• Custom app behavior

These concepts frequently appear in implementation scenarios.

6. Troubleshooting and Debugging

Automation rarely works perfectly on the first attempt.

Expect questions involving:

• Failed playbook execution

• API communication issues

• Data mapping errors

• Logging analysis

• Debugging techniques

Being able to identify root causes quickly is a valuable real-world skill and a common exam objective.
