SPLK-1001 Practice Exam Questions with Answers Splunk Core Certified User Certification

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 as index=security and sourcetype=linux.
• Using the OR operator to combine multiple values for the same field, such as (invalid OR failed).
• Using the | character to separate commands, such as stats count as "Potential Issues".
• Using the as keyword to rename fields, such as count as "Potential Issues".

Explanation/Reference:

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.

According to the Splunk documentation, dashboards are collections of views that you can use to visually analyze your data. You can create dashboards using simple XML, or use the Splunk Web framework to build custom dashboards using HTML, CSS, and JavaScript.

Dashboards consist of one or more panels that display data in a variety of ways. You can use charts, tables, maps, single value indicators, and other visualizations to display your data. You can also add interactive elements to your dashboards, such as filters, drilldowns, and time range pickers, to make them more dynamic and user-friendly.

To create a dashboard panel from a search result, you can use the Save As button in the Search app and select Dashboard Panel. This will open a dialog box where you can choose an existing dashboard or create a new one, and specify the panel title and visualization type. You can also edit the panel properties and permissions before saving it to the dashboard.

Alternatively, you can create a report from a search result and then add it to a dashboard as a panel. Reports are saved searches that include additional attributes such as a visualization type, permissions, and an optional description. You can create reports using the Save As button in the Search app and select Report. To add a report to a dashboard, you can use the Add to Dashboard button in the Reports listing page or in the report itself.

Dashboards must have a unique dashboard ID within a permission’s context. This means that you cannot have two dashboards with the same ID in the same app or user space. The dashboard ID is used to reference the dashboard in URLs and XML files. You can specify the dashboard ID when you create a new dashboard using simple XML or the Splunk Web framework. If you do not specify an ID, Splunk software will generate one based on the dashboard title.

Splunk alerts are based on searches that run on a schedule or in real time. You can use alerts to monitor for and respond to specific events or conditions in your data. Alerts use a saved search to look for events in real time or on a schedule. Alerts trigger when search results meet specific conditions. You can use alert actions to respond when alerts trigger, such as sending an email, running a script, or creating a ticket1.

You can create alerts from the Search app, the Alerts page, or the Dashboards app. You can also use the Splunk Web framework to create custom alert actions using Python or JavaScript1.

Dashboards, webhooks, and reports are not the basis for Splunk alerts, although they can be related to them. Dashboards are collections of views that display data visually in a variety of ways. You can add alert panels to dashboards to show the status of your alerts2. Webhooks are a type of alert action that send HTTP POST requests to a specified URL when an alert triggers. You can use webhooks to integrate Splunk alerts with external systems or applications3. Reports are saved searches that include additional attributes such as a visualization type, permissions, and an optional description. You can create reports from search results and add them to dashboards as panels. You can also use reports as the basis for scheduled or real-time alerts.

 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.

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

The SPL search specified above will return 10 rows of results by default, as the "top" command specifies a limit of 10 results. The query will search for all events in the security index with a sourcetype of linuxsecure that contain either the terms fail* or invalid and will display the top 10 results according to the src_ip field.
