SPLK-1004: Splunk Core Certified Advanced Power User

The append command in Splunk is often used with a subsearch to add additional data to the end of the primary search results, and it can access historical data (Option B). This capability is useful for combining datasets from different time ranges or sources, enriching the primary search results with supplementary information.

The typeof function in Splunk returns a string that represents the data type of the evaluated expression. The potential string results include 'Number', 'String', and 'Null' (Option C). These indicate whether the evaluated expression is a numerical value, a string, or a null value, respectively, helping users understand the data types they are working with in their searches and scripts.

In Splunk dashboards, event annotations are used to add informative overlays on timeline visualizations to mark significant events. The required element attribute to define an event annotation within a dashboard panel is <search type='annotation'> (Option D). This attribute specifies that the search within this element is intended to generate annotations, which are then overlaid on the timeline based on the time and information provided by the search results.

A tsidx file in Splunk is an index file that contains indexed data, and it consists of two main parts: a lexicon and a posting list (Option C). The lexicon is a list of unique terms found in the data, and the posting list is a list of references to the occurrences of these terms in the indexed data. This structure allows Splunk to efficiently search and retrieve data based on search terms.

To disable the inspect button on a dashboard panel in Splunk, you can set the link.inspect.visible attribute to 0 (Option B) in the panel's source code. This attribute controls the visibility of the inspect button, and setting it to 0 hides the button, preventing users from accessing the search inspector for that panel.

Splunk supports the use of external lookups, which can be scripts or binary executables that enrich search results with external data. These external lookups can be written in various scripting languages or compiled as binary executables. Among the options given, Python and binary executables (Option D) are commonly used for creating external lookups in Splunk. Python is a widely used programming language that can easily interact with Splunk's API and data structures, and binary executables can be used for more complex or performance-critical lookup operations. Perl and Ruby (Options A and B) are less commonly used in this context, and Perl combined with binary executables (Option C) is not as standard for Splunk external lookups as Python.
