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 security analyst wants to find IP addresses that have attempted to access a specific URL more than 5 times in the last hour and also have a user agent string containing "curl". They need to use a subsearch to pre-filter IPs. Which search is correct?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
index=web sourcetype=access [search useragent=*curl* | stats count by src_ip | where count>5 | fields src_ip] | stats count by src_ip | where count>5
Option B is correct because it uses a subsearch to first find IPs that have accessed the URL more than 5 times with a user agent containing 'curl', then passes those IPs to the outer search to filter the original data. The subsearch returns a list of src_ip values, which the outer search uses as a filter, ensuring only IPs meeting both conditions are counted again. This matches the requirement to pre-filter IPs using a subsearch.
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.
✗
[search index=web sourcetype=access useragent=*curl* | stats count by src_ip | where count>5] | fields src_ip
Why it's wrong here
Subsearch returns only fields, not a search string for main search.
✓
index=web sourcetype=access [search useragent=*curl* | stats count by src_ip | where count>5 | fields src_ip] | stats count by src_ip | where count>5
Why this is correct
Correctly uses subsearch to filter IPs, then counts and filters.
Related concept
Read the scenario before looking for a memorised answer.
✗
index=web sourcetype=access | search useragent=*curl* | stats count by src_ip | where count>5
Why it's wrong here
Does not use a subsearch as required.
✗
index=web sourcetype=access ( useragent=*curl* ) | stats count by src_ip | where count>5
Why it's wrong here
Syntax error: missing search prefix and parentheses misuse.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse a subsearch with a simple filter or stats command, leading them to choose options that either omit the subsearch syntax or place it incorrectly, such as at the start without proper piping.
Detailed technical explanation
How to think about this question
In Splunk, a subsearch is enclosed in square brackets and runs first, returning its results as a set of values that the outer search uses as a filter. The subsearch in option B uses 'fields src_ip' to output only the IP addresses, which the outer search implicitly matches against the src_ip field. This approach is efficient for reducing data volume early in the pipeline, especially when dealing with large datasets like web access logs.
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.

What is the correct answer to this question?
The correct answer is: index=web sourcetype=access [search useragent=*curl* | stats count by src_ip | where count>5 | fields src_ip] | stats count by src_ip | where count>5 — Option B is correct because it uses a subsearch to first find IPs that have accessed the URL more than 5 times with a user agent containing 'curl', then passes those IPs to the outer search to filter the original data. The subsearch returns a list of src_ip values, which the outer search uses as a filter, ensuring only IPs meeting both conditions are counted again.
