The answer is that the eval command uses match which is case-sensitive, so the search returns no results because admin usernames may start with lowercase 'admin' rather than the uppercase 'Admin' specified in the match function. The match function in Splunk's eval command performs a case-sensitive comparison, meaning it only matches the exact string pattern provided; if the data contains 'admin' (lowercase) but the eval checks for 'Admin' (capital A), every user is assigned account_type='user', and the subsequent where clause filtering for account_type='admin' fails to find any results. On the Splunk Core Certified User SPLK-1002 exam, this question tests your understanding of string comparison functions in eval, particularly the case-sensitivity of match versus other functions like like or cidrmatch, and it often appears as a common trap where candidates overlook case differences in real-world data. A helpful memory tip is to remember that match is strict and case-sensitive, so always check your data's actual casing before using it in a conditional eval.
SPLK-1002 Practice Question: Creating Reports, Dashboards and Visualizations
This SPLK-1002 practice question tests your understanding of creating reports, dashboards and visualizations. 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.
Exhibit
index=security sourcetype=windows_security
| eval account_type=if(match(user, "^Admin"), "admin", "user")
| stats count by account_type, action
| where account_type="admin" AND action="Failed"
| sort - count
| head 5
Refer to the exhibit. A security analyst runs this search to find top failed actions for admin accounts. The search returns no results, but there are failed actions for admin accounts in the data. What is the most likely cause?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "most likely"
Why it matters: Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The eval command uses match which is case-sensitive; the admin usernames may start with lowercase 'admin'.
The where clause filters results after stats, but if the account_type eval does not match any user starting with 'Admin' (case-sensitive), then account_type will be 'user' for all, and the where condition fails. The match function is case-sensitive; users may start with 'admin' lowercase.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
The windows_security sourcetype does not contain a 'user' field.
Why it's wrong here
User field is standard in security logs.
✓
The eval command uses match which is case-sensitive; the admin usernames may start with lowercase 'admin'.
Why this is correct
Correct. match is case-sensitive; use lower() or case-insensitive regex.
Clue confirmation
The clue word "most likely" in the question point toward this answer.
Related concept
Read the scenario before looking for a memorised answer.
✗
The where clause should use 'search' instead.
Why it's wrong here
Where is appropriate for filtering after stats.
✗
The stats command should be before eval.
Why it's wrong here
Order is fine; eval before stats works.
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-1002 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.
