- A
The macro definition includes empty parentheses 'failed_logins()' but is being called without parentheses, causing Splunk to treat it as a different macro.
The macro is defined with parentheses, so it expects to be called with parentheses even if no arguments. Alternatively, define without parentheses.
- B
The macro does not have read permissions for the security team.
Why wrong: If it worked before, permissions are unlikely the cause.
- C
The macro must be called with backticks like `failed_logins` instead of pipe.
Why wrong: Macros are called with pipe or backticks depending on context; backticks are for evaluating the macro inline but pipe works too.
- D
The sourcetype field is using a wildcard, which is deprecated.
Why wrong: Wildcards are still supported in sourcetype fields.
Quick Answer
The answer is D: the macro definition includes empty parentheses but is called without them, causing Splunk to treat it as a different macro. When a macro is defined with empty parentheses like `failed_logins()`, Splunk interprets those parentheses as a parameter list expecting an argument, even if that argument is empty. Calling the macro as `failed_logins` without parentheses makes Splunk look for a separate macro literally named `failed_logins`—which doesn’t exist—so the search returns no results. This question tests your understanding of Splunk macro syntax and how parentheses affect macro resolution, a common trap on the SPLK-1003 exam where candidates confuse definition syntax with invocation syntax. The key distinction is that `define failed_logins()` creates a macro with one empty argument, while `define failed_logins` creates a parameterless macro; calling them interchangeably breaks the search. Memory tip: “Parentheses in definition demand parentheses in call—no parentheses, no match.”
SPLK-1003 Macros, Saved Searches and CIM Practice Question
This SPLK-1003 practice question tests your understanding of macros, saved searches and cim. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A security team has a saved search that runs every 5 minutes and looks for 'FAILED' events in Windows Security logs. The search uses a macro 'failed_logins' defined as: `define failed_logins() [search index=windows sourcetype=WinEventLog:Security EventCode=4625]`. Recently, the team noticed that the search is returning no results even though there are failed login events. What is the most likely issue?

Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
The macro definition includes empty parentheses 'failed_logins()' but is being called without parentheses, causing Splunk to treat it as a different macro.
Option D is correct because the macro is defined with a parameter list (parentheses) but no arguments are passed, so Splunk treats it as a macro with one empty argument, which can cause the search to not run correctly if the macro is called without parentheses. Option A is incorrect because wildcards are fine. Option B is incorrect because macros do not require backticks. Option C is incorrect because permissions are set per macro, but if it worked before, permissions are likely not the issue.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the SPLK-1003 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
