A tag is a descriptive label that you can apply to one or more fields or field values in your events1.You can use tags to simplify your searches by replacing long or complex field names or values with short and simple tags1.To search for events that contain a tag name, you can use the tag keyword followed by an equal sign and the tag name1.You can also use wildcards (*) to match partial tag names1. Therefore, option B is correct because it will return events that contain a tag name that starts with Pri. Options A and D are incorrect because they will only return events that contain an exact tag name match. Option C is incorrect because it will return events that contain a tag name that starts with Priv, not Privileged.

This search uses the transaction command to group events that share a common value for JSESSIONID into transactions1.The transaction command assigns a duration field to each transaction, which is the difference between the latest and earliest timestamps of the events in the transaction1.The search then uses the timechart command to create a time-series chart of the average duration of each transaction1. Therefore, option A is correct because it describes the search accurately. Option B is incorrect because the search does not use the stats command or the pause field.Option C is incorrect because the transaction command does not require the startswith and endswith options, although they can be used to specify how to identify the beginning and end of a transaction1.Option D is incorrect because the transaction command does not have to be the last command in the search pipeline, although it is often used near the end of a search1.

'Calculated fields can reference all types of field extractions and field aliasing, but they cannot reference lookups, event types, or tags.'

The rex command allows you to extract fields from events using regular expressions. You can use the rex command to specify a named group that matches the port number in the event. For example:rex '\+\+\+\+port (?\d+)'This will create a field called port with the value 54 for the event.The delimiter method is not suitable for this event because there is no consistent delimiter between the fields. The regular expression method is not a valid option for the Field Extractor tool. The Field Extractor tool can extract regular expressions, but it is not a method by itself.

To use a search macro in a search string, you need to place a back tick character (`) before and after the macro name1. You also need to use the same number of arguments as defined in the macro2. The macro weekly sales (2) has two arguments: Price and AmountSold. Therefore, you need to provide two values for these arguments when you call the macro.The option A is incorrect because it uses parentheses instead of back ticks around the macro name. The option B is incorrect because it uses underscores instead of spaces in the macro name. The option D is incorrect because it uses spaces instead of commas to separate the argument values.

This is because event types are added to events as a field named eventtype, and you can use this field as a search term to find events that match a specific event type. For example, eventtype=successful_purchases returns all events that have been categorized as successful purchases by the event type definition. The other options are incorrect because they either use a different field name (tag), a different syntax (Event Type:: or event type---), or have a typo (success ful_purchases).You can learn more about how to use event types in searches from the Splunk documentation1.

The correct answer is C. 'weekly_sales (3.99, 10)'. This is because search macros accept arguments without quotation marks or dollar signs, and the number of arguments must match the number of parameters defined in the macro. The other options are incorrect because they either use quotation marks or dollar signs around the arguments, or they provide a different number of arguments than the macro expects. You can learn more about how to use search macros in searches from the Splunk documentation1. 

A calculated field is a field that you create based on the value of another field or fields1.You can use calculated fields to enrich your data with additional information or to transform your data into a more useful format1.Calculated fields can be based on extracted fields, which are fields that are extracted from your raw data using various methods such as regular expressions, delimiters, or key-value pairs1. Therefore, option B is correct, while options A, C and D are incorrect because tags, output fields for a lookup, and fields generated from a search string are not types of extracted fields.

The correct way to execute the macro in a search string is to use the formatmacro_name($arg1$, $arg2$, ...)where$arg1$,$arg2$, etc. are the arguments for the macro. In this case, the macro name isconvert_salesand it takes three arguments:currency,symbol, andrate. The arguments are enclosed in dollar signs and separated by commas. Therefore, the correct way to execute the macro isconvert_sales($euro$, $$, .79).

Data model acceleration is a feature that speeds up searches on data models by creating and storing summaries of the data model datasets1.To enable data model acceleration, you must have administrative permissions or the accelerate_datamodel capability1. Therefore, option D is correct.Accelerated data models cannot be edited unless you disable the acceleration first1. Therefore, option B is correct.Private data models cannot be accelerated because they are not visible to other users1. Therefore, option C is correct.Root events can be accelerated as long as they are not based on a search string1. Therefore, option A is incorrect.
