The correct answer is C and D because these are the valid post-processing searches. A post-processing search is a type of search that applies additional filters or transformations to the results of a base search. A post-processing search can use any SPL command that does not require access to the raw data, such as stats, search, eval, and chart. Option C is correct because it uses the stats command to aggregate the count by log level. Option D is correct because it uses the search command to filter the results by log level and then uses the stats command to aggregate the count by component. Option A is incorrect because it uses the tstats command, which is not a valid post-processing command, as it requires access to the raw data. Option B is incorrect because it uses the sourcetype field, which is not available in the results of the base search, as it only returns the component and log_level fields. You can find more information about the post-processing searches in the  Splunk Developer Guide .

The correct answer is A, B, and D because these are the examples of a Splunk KV store use case. A Splunk KV store is a service that allows you to store and manage custom data in Splunk, using key-value pairs. A Splunk KV store can be used for various purposes, such as storing checkpoint data, tracking workflow, and storing application state. Option A is correct because a Splunk KV store can store checkpoint data for modular inputs, which are custom data inputs that use external scripts or binaries to collect and send data to Splunk. Checkpoint data is used to keep track of the data collection progress and resume from the last point in case of interruption. Option B is correct because a Splunk KV store can track workflow in an incident-review system, which is a system that allows you to review and manage the incidents that occur in your environment. Workflow data is used to store the status, priority, and assignee of each incident. Option D is correct because a Splunk KV store can store application state as a user interacts with an app, which is a custom interface that allows you to access and analyze the data in Splunk. Application state data is used to store the user preferences, settings, and selections for the app. Option C is incorrect because a Splunk KV store cannot index metrics data from remote HTTP sources, which are sources that send numerical data to Splunk via HTTP or HTTPS. Metrics data is not stored in the Splunk KV store, but rather in the metrics index, which is a special type of index that optimizes the storage and retrieval of metrics data. You can find more information about the Splunk KV store and its use cases in the  Splunk Developer Guide .

The correct answer is A, B, and D because these are the criteria that the search must meet in order to successfully accelerate a report. A report is a saved search that runs on a schedule and returns results in a table or a chart. A report can be accelerated to improve its performance and reduce the load on the Splunk indexers. Option A is correct because the search cannot use event sampling, which is a technique that reduces the number of events returned by the search. Event sampling can affect the accuracy and consistency of the report results. Option B is correct because the search must use a transforming command, which is a command that converts the results into a data table with rows and columns. Transforming commands are required for report acceleration, as they enable the creation of summary data. Option D is correct because the commands before the first transforming command must be streamable, which means they can process each event as it is returned by the search. Streamable commands are preferred for report acceleration, as they reduce the memory usage and improve the performance of the search. Option C is incorrect because the search does not need to use a standard Splunk visualization, which is a type of chart or graph that displays the results. The search can use any visualization that is compatible with the report acceleration. You can find more information about report acceleration and the criteria for the search in the  Splunk Developer Guide .

 The correct answer is A and B, because for a KV Store, a lookup stanza in the transforms.conf file must contain the collection and fields_list attributes. A lookup stanza is a configuration section in the transforms.conf file that defines the properties of a lookup, such as the lookup type, the lookup file or collection, the input and output fields, and the match type. A lookup is a feature that allows Splunk to enrich the events with additional data from an external source, such as a CSV file or a KV Store collection.  For a KV Store lookup, the lookup stanza must have the collection attribute, which specifies the name of the KV Store collection to use, and the fields_list attribute, which specifies the fields to return from the KV Store collection 2 . The external_type and internal_type attributes are not required for a KV Store lookup, but for a scripted lookup, which is a type of lookup that uses an external script to perform the lookup operation.

 The correct answer is B and D, because they are the ways to optimize the searches in the dashboard. A dashboard is a user interface that displays data from one or more searches in various panels, such as charts, tables, or maps. Optimizing the searches in the dashboard helps to improve the dashboard performance, reduce the load on the Splunk server, and enhance the user experience. Restricting the time range of the search as much as possible and converting the common SPL into a Global Search and converting the other searches to post-processing searches are both methods to optimize the searches in the dashboard by limiting the amount of data to be searched or processed. Converting searches to include NOT expressions and replacing | stats command with | transaction command wherever possible are not methods to optimize the searches in the dashboard, but rather ways to change the search logic or functionality, which might not produce the desired results.

The correct answer is A, B, and C because these are the benefits of using Simple XML Extensions. Simple XML Extensions allow you to customize the appearance and behavior of your dashboards by adding custom layouts, graphics, and behaviors. You can also use JavaScript and CSS to enhance your dashboards. Option D is incorrect because Simple XML Extensions do not affect the Splunk license consumption based on host. You can find more information about Simple XML Extensions in the  Splunk Developer Guide .

The token filter that encodes URL values is tokenn ​ ame ∣ u . This filter applies the URL encoding to the token value, which replaces special characters with percent-encoded characters. This is useful for passing token values as query parameters in a drilldown. The other token filters are either invalid or used for different purposes. For more information, see [Token filters] .

 The correct answer is B, C, and D, because they are all valid parent elements for the event action shown below. The event action is a < set > element, which is used to set the value of a token based on a user interaction, such as a click or a change. The < set > element can be nested inside a < change > , a < condition > , or a < drilldown > element, depending on the type and context of the event. The < eval > element is not a valid parent element for the < set > element, but a sibling element that can be used to evaluate an expression and set the value of a token.

A Splunk custom visualization is a visualization that uses the Splunk Custom Visualization API. This API lets you create your own visualizations using JavaScript, HTML, and CSS. You can also use third-party libraries or frameworks to create custom visualizations. The other options are not custom visualizations, but rather variations of the built-in visualizations in Splunk. For more information, see [Custom visualizations overview].

 The correct answer is B because when calling the serviceNS endpoint, you must specify the user and app context in the URI. The serviceNS endpoint is a REST endpoint that allows you to access the Splunk service for a specific namespace. The namespace is a combination of the user and the app context, which determine the scope and visibility of the knowledge objects in Splunk. The serviceNS endpoint requires you to specify the user and app context in the URI, such as /servicesNS/{user}/{app}. Option A is incorrect because you do not need to authenticate with an admin user, but rather with the user of the required context. Option C is incorrect because you do not need to authenticate with the user of the required context, but rather with any valid user. Option D is incorrect because you do not need to pass the user and app context in the request payload, but rather in the URI. You can find more information about the serviceNS endpoint and the namespace in the  Splunk REST API Reference Manual .
