SPLK-1002 Basic Searching and Transforming Commands Practice Question
This SPLK-1002 practice question tests your understanding of basic searching and transforming commands. 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.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The 'case' function cannot compare IP addresses to CIDR ranges
The `case` function in SPL cannot compare IP addresses to CIDR ranges directly because it expects boolean expressions, not IP-matching operators. The correct approach is to use the `cidrmatch` function within the `case` function to evaluate whether `src_ip` falls within a given CIDR range. Without `cidrmatch`, the comparison `src_ip='10.0.0.0/8'` is treated as a string equality check, which will never match an IP address to a CIDR notation string.
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 'src_ip' field is not extracted
Why it's wrong here
It is extracted.
✗
The default condition should be 'true()' instead of '1=1'
The 'case' function cannot compare IP addresses to CIDR ranges
Why this is correct
Correct: case uses exact string comparison, not subnet matching.

✗
The 'search' command should be before 'eval'
Why it's wrong here
Order is fine.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Splunk often tests the misconception that the `case` function can handle any comparison operator, including CIDR matching, when in fact it requires explicit use of `cidrmatch` for IP subnet evaluation.
Detailed technical explanation
How to think about this question
The `cidrmatch` function in SPL uses the underlying IP address library to perform subnet matching according to RFC 4632, converting both the IP and CIDR prefix into binary form for comparison. A common real-world scenario is building a dynamic threat intelligence lookup where you need to classify source IPs into trusted or untrusted zones based on CIDR blocks, which requires `cidrmatch` inside `case` or `if` statements. Without it, the `case` function treats the CIDR string as a literal, causing all comparisons to fail and the default condition to be applied.
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 network engineer segments a warehouse floor into three subnets: 20 scanners, 5 printers, and 2 management hosts. Picking the wrong mask wastes addresses or leaves too few usable hosts. Exam questions test whether you can apply CIDR notation, calculate block size, and identify the correct usable-host range for a given prefix.
