Community Insight

The exam tests your ability to distinguish between what's allowed and what's recommended; pipes are allowed, but tags are not, and joins are best avoided.

When defining a Splunk event type, the search string can include pipes, allowing you to chain commands. Community consensus and Splunk docs confirm that pipes are allowed, while tags are forbidden.

Choosing 'Joins' because they seem allowed, while forgetting that pipes are also allowed and are actually the correct answer; don't overthink restrictions that apply to tags.

B. Pipes When creating an event type in Splunk, you can use pipes (|) to chain multiple search commands together. Pipes allow for the transformation and filtering of search results effectively.

My option is B: Explanation: A. Joins: While joins may be technically possible in some queries, they can complicate event type definitions and are generally not recommended for simple event types. B. Pipes: This is correct. Pipes (|) can be used in the search string for an event type to chain commands together, allowing for the use of commands like stats, eval, or where within the event type definition. C. Subsearches: Subsearches can be complex and are typically not used in the definition of event types due to the potential performance and complexity issues. D. Tags: Tags are related to classification and organization of events but are not part of the search string when creating an event type. Therefore, the allowed element in the search string when creating an event type is B. Pipes.

Restrictions show only Join not listed in the restricted part of event type search strings "Restrictions Splunk software processes event types first by priority score and then by ASCII sort order. Search strings that define event types cannot reference tags, because event types are always processed and added to events before tags." "You cannot base an event type on a search that: Includes a pipe operator after a simple search. Includes a subsearch."

Expert Analysis

Why the Answer Is Correct

Pipes are explicitly permitted in Splunk event type search strings. They let you chain commands like stats, eval, and where to refine which events the event type matches. This is confirmed by both the Splunk documentation and the majority of candidates in the poll. While some might think complex constructs are prohibited, pipes are a standard and supported part of event type definitions.

Why the Other Options Are Wrong

Joins (A) are technically possible but not recommended, as they add unnecessary complexity to event type definitions. Subsearches (C) are not the key allowed component here, and their use in event types is less common. Tags (D) are explicitly forbidden because event types are processed before tags are applied, making tags unavailable in the event type search string. The question specifically asks what is allowed, and only pipes are clearly and unambiguously allowed in this context.

Community Comment Notes

Comment 1 correctly identifies pipes as the answer and explains why joins are overly complex. Comment 2 reinforces the idea that pipes are used to chain commands, which is a fundamental feature of Splunk search strings. Comment 3 attempts to argue for joins, but its reference to restrictions actually highlights the distinction between what is prohibited (tags) and what is permitted (pipes). Taking a balanced view of the comments and the official documentation, option B is the correct choice.

Exam Strategy

When answering questions about event type search strings, remember that pipes are your best friend—they allow you to use transforming commands. Don't confuse 'allowed' with 'recommended'; even if joins are possible, they are not the best answer. Focus on the explicit restriction on tags.
