SPLK-1002 Splunk Core Certified Power User Study Guide

Exam Overview

The Splunk Core Certified Power User certification validates a candidate's ability to navigate the Splunk user interface and utilize the platform's searching and reporting commands effectively. It is designed for users who want to master the creation of complex knowledge objects, use lookups, and apply advanced statistical analysis to their data to generate actionable insights.

Exam Domains

• Basic Searching and Search Results
• Using Fields in Searches
• Search Language Fundamentals
• Using Transforming Commands
• Creating Visualizations
• Creating and Managing Lookups
• Creating Knowledge Objects
• Calculating Statistics
• Manipulating Data with eval and where

Key Concepts & Common Difficulties

• Search Optimization: Candidates often struggle with writing efficient searches that do not time out on large datasets. The correct approach involves filtering events as early in the search pipeline as possible using the tstats command or indexed fields before performing expensive operations like join or transaction.
• Eval vs. Where: Confusion frequently arises regarding when to use eval versus where commands. Remember that eval creates new fields based on an expression for every event, while where filters results based on a conditional expression; use where to discard events early to improve performance.
• Lookup Definitions: Many find the distinction between automatic lookups and explicit lookups confusing. The key is understanding that automatic lookups run silently in the background based on configuration files, whereas explicit lookups allow for more granular control over field matching and output within the search string.
• Subsearches: Subsearches can be difficult to conceptualize, particularly regarding their execution order and performance impact. Candidates should focus on understanding that a subsearch runs first and passes its results to the main search, often formatted as a search condition or a list of values.

Study Strategy

• Prerequisites: Ensure you are comfortable with the Splunk interface and basic search commands from the Splunk Core Certified User level before starting this advanced study material.
• Topic Order: Begin with the Search Processing Language (SPL) syntax and transforming commands, then move on to creating knowledge objects like tags, event types, and macros to organize your data.
• Hands-on Practice: Spend significant time in a Splunk instance creating lookups and calculated fields; practical application is essential for retaining how these objects interact with data during searches.
• Review Documentation: Regularly consult the Splunk Docs for specific command syntaxes and arguments, as the exam requires precise knowledge of function usage and statistical evaluation.
• Exam Day Tips: Read the questions carefully to identify exactly which knowledge object or command is being asked for, and manage your time effectively to ensure you can answer all questions.
