Splunk SPLK-1001 Practice Test - Questions Answers, Page 24

The Power role contains the minimum permissions required to have write access to Splunk alerts.

The User role can only view alerts created by others, but cannot create or modify them. The Alerting role is not a default role in Splunk, but a custom one that can be created by an administrator. The Admin role has write access to Splunk alerts, but also has many other permissions that are not necessary for alerting3.

In the Search and Reporting app, _time is a default selected field. This means that it is always displayed in the events list and table views, unless explicitly deselected. Other default selected fields are host, source, and sourcetype. Index and action are not default selected fields, but they can be added to the list of selected fields by clicking on All Fields4.

Fields are searchable key/value pairs in event data. They allow you to specify criteria for your searches and filter out unwanted events. Fields can be extracted automatically by Splunk software during indexing or searching, or manually by users using various methods. Fields are not inherent entities that exist in event data, but rather interpretations of data by Splunk software or users. Fields are not values pulled exclusively from lookup tables, although lookup tables can be used to add fields to events based on existing fields. Fields are not non-searchable name/value pairs used while indexing data, but rather searchable attributes that can be used to refine searches5.

The four types of lookups that Splunk provides out-of-the-box are file-based, external, KV Store, and geospatial. File-based lookups use CSV files to map fields from your data to fields in the external table. External lookups use Python scripts or binary executables to populate your events with field values from an external source. KV Store lookups use a key-value store to map fields from your data to fields in the external table. Geospatial lookups use KMZ or KML files to match location coordinates in your events to geographic feature collections1.

The difference between real-time and relative time ranges in the time picker is that real-time searches display results from a rolling time window, such as the last 15 minutes, while relative searches display results from a set length of time, such as yesterday or last week. Real-time searches do not happen instantly, but rather update periodically based on the refresh interval. Relative searches do not happen at a scheduled time, but rather when the user runs them. Real-time searches do not run constantly in the background, but rather when the user starts them. Real-time searches do not represent events that have happened in a set time window, but rather events that are happening now.

The best description of Splunk Apps is a collection of files that provide specific functionality or views of your data. Splunk Apps can be built by anyone, not only by Splunk employees. Splunk Apps are not only available for download on Splunkbase, but also can be created or customized by users. Splunk Apps are not available on iOS and Android, but rather on Splunk Enterprise or Splunk Cloud platforms.

This means that you can use the index field to filter your search results by the name of the index that contains the events you want to see.

For example, if you want to search for events in the index named ''gcp_logs'', you can use the following SPL:

index=gcp_logs

You can also specify multiple indexes by using the OR operator, such as:

index=gcp_logs OR index=oswin

This is the appropriately formatted SPL search because it follows the SPL syntax rules12, such as:

Using the=operator to specify field-value pairs, such asindex=securityandsourcetype=linux.

Using theORoperator to combine multiple values for the same field, such as(invalid OR failed).

Using the|character to separate commands, such asstats count as 'Potential Issues'.

Using theaskeyword to rename fields, such ascount as 'Potential Issues'.

Using a minus sign (-) for descending order and a plus sign (+) for ascending order. If no sign is specified, the default order is ascending.

Sorting by multiple fields in the order they are specified. If there are duplicate values in one field, the next field is used to break the tie.

Sorting by field values according to their types. If the field type is not specified, the sort command tries to automatically determine it.
