What Type of Command Is eval in Splunk?
What type of command is eval?
Community Votes
80% of anonymous learners picked answer A. Votes are pick records left by other test-takers — they are not the verified answer.
Community Insight
This question tests your understanding of Splunk's command classification system, specifically the difference between 'streaming' and 'distributable streaming'—a common trap for learners.
The Splunk community identifies eval as a distributable streaming command, with option A receiving 80 votes versus 20 for option C. Official Splunk documentation confirms this classification.
Option C ('Streaming in some modes') is the most common incorrect answer because eval processes results row-by-row like a streaming command, but Splunk officially categorizes it as 'distributable streaming' since it can be executed on indexers.

Expert Analysis
Why the Answer Is Correct
The official Splunk documentation on command types, cited in comments [1] and [2], lists eval under 'Distributable streaming' commands. These commands can be distributed to indexers, meaning they run on indexers before results are sent to the search head. Eval is a classic example because it computes new fields on a per-event basis and can operate in a distributed manner. Comment [4] also references a study guide page (PG 301 F2) supporting option A, reinforcing the documented classification.
Why the Other Options Are Wrong
Option B ('Report generating') is incorrect because eval does not transform events into statistical results or produce report-like output; it only creates or modifies fields. Option D ('Centralized streaming') is the opposite of eval's behavior—centralized streaming commands run only on the search head, while eval can run on indexers. Option C ('Streaming in some modes') is partially intuitive because eval is indeed a streaming command, but the qualifier 'in some modes' is misleading; Splunk docs place eval squarely in the distributable streaming category, not just a conditional streaming command.
Community Comment Notes
The comment section shows a clear split: most contributors (80) chose A, backed by official documentation links, while a smaller group (C, 20) argued that eval is 'streaming in some modes.' One comment (comment [3]) attempted to justify C by noting that eval can be used in distributed environments but claimed it is not 'specifically categorized as distributable streaming'—this is factually incorrect according to the official table. The documentation links provided in comments [1] and [2] are the authoritative source and should be your primary reference for command type classifications.

Exam Strategy
Memorize the five Splunk command types—streaming, distributable streaming, generating, report generating, and centralized streaming—and note which commands fall into each. Eval is a frequent exam example for 'distributable streaming', so always check the official command type table when a question asks for a command's classification.
