Which of the following is a best practice for searching in Splunk?

Question

Options

• AStreaming commands run before aggregating commands in the Search pipeline.
• BRaw word searches should contain multiple wildcards to ensure all edge cases are covered.
• CLimit fields returned from the search utilizing the cable command.
• DSearching over All Time ensures that all relevant data is returned.

• B
  3% (1)
• C
  93% (28)
• D
  3% (1)

Explanation

Limiting returned fields via a command like fields or table is a Splunk performance best practice because it reduces the volume of data processed downstream in the pipeline, speeding up results and lowering resource consumption - option C captures this principle correctly (note: "cable" in the option text is almost certainly a typo for the table command; the underlying concept is what the exam is testing).

Why the distractors are wrong:

• A - Streaming commands running before aggregating commands is simply how Splunk's internal pipeline works, not a best practice you choose to apply; it's a description of architecture, not guidance.
• B - Multiple wildcards are actually harmful; leading/trailing wildcards (e.g., *foo*) force full index scans and severely hurt performance. Best practice is to minimize wildcards.
• D - Searching over "All Time" is one of the worst habits in Splunk; it forces a scan of the entire index. Always narrow your time window to the smallest useful range.

Memory tip: Think "Narrow everything" - narrow your time range, narrow your fields, and narrow your wildcards. Any option that suggests broadening (All Time, multiple wildcards) is wrong; any option that suggests narrowing (limit fields) is right.
