SPLK-1003 Advanced Searching and Statistics Practice Question
This SPLK-1003 practice question tests your understanding of advanced searching and statistics. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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 Splunk admin wants to track the number of unique users who accessed a system each hour over the past 24 hours. Which search provides the correct result?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
index=main earliest=-24h | timechart span=1h dc(user) as unique_users
Option A is correct because it uses `timechart span=1h dc(user)` to count distinct users per hour over the last 24 hours. The `dc()` function calculates distinct counts, and `span=1h` sets the time bucket to one hour, exactly matching the requirement.
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.
✓
index=main earliest=-24h | timechart span=1h dc(user) as unique_users
Why this is correct
dc(user) gives distinct count of users per hour with timechart.
Related concept
Read the scenario before looking for a memorised answer.
stats by _time creates one row per second, not hourly bins. timechart would then use those tiny bins.
✗
index=main earliest=-24h | timechart span=1h count by user
Why it's wrong here
This creates separate series for each user, not a single count of unique users.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is confusing `count` (total events) with `dc()` (distinct values), and assuming `values()` or `count by user` can produce a unique user count per time period.
Detailed technical explanation
How to think about this question
The `timechart` command implicitly uses `_time` as the x-axis and applies the `span` argument to create fixed-width time buckets. The `dc()` function (distinct count) leverages the `tstats` acceleration when available, making it efficient for large datasets. In real-world scenarios, using `dc()` with `timechart` is essential for accurate user activity monitoring, as it correctly handles deduplication across events within each time bucket.
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.
TExam Day Tips
→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.
