SPLK-1001 Splunk Core Certified User Questions and Answers

This is the correct answer because roles determine the level of access that users have to the Splunk platform and the tasks that they can perform on the platform1. Roles can contain one or more capabilities that provide access to specific parts of the Splunk platform, such as searching, indexing, alerting, and so on2. Roles can also specify which indexes that a user can search and which indexes are searched by default1.

 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 fields sidebar in Splunk shows the default fields and the interesting fields for the events that match your search. The default fields are host, source, and sourcetype, which are extracted for every event at index time. The interesting fields are fields that appear in at least 20% of the events in your search results. You can also select additional fields to display in the fields sidebar1.

By default, the index field is not listed in the fields sidebar, because it is not a default field nor an interesting field. The index field is a metadata field that indicates which index the event belongs to. Metadata fields are not extracted from the event data, but are added by the indexer as part of the indexing process. Metadata fields are not shown in the fields sidebar, but you can use them in your search queries2.

Therefore, among the four options, only sourcetype would be listed in the fields sidebar under interesting fields by default.

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.

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.

The search query index=myindex source=c: \mydata. txt NOT error=* specifies three criteria for the events to be returned:

• The index must be myindex, which is a user-defined index that contains the data from a specific source or sources.
• The source must be c: \mydata. txt, which is the name of the file or directory where the data came from.
• The error field must not exist in the events, which is indicated by the NOT operator and the wildcard character (*).

The NOT operator negates the following expression, which means that it returns the events that do not match the expression. The wildcard character () matches any value, including an empty value or a null value. Therefore, the expression NOT error= means that the events must not have an error field at all, regardless of its value.

The search query does not use quotation marks around the source value, which means that it is case-sensitive and exact. If there are any variations in the source name, such as capitalization or spacing, they will not match the query.

When looking at a dashboard panel that is based on a report, you cannot modify the search string in the panel, but you can change and configure the visualization. This is because the dashboard panel inherits the search string from the report, and any changes to the search string will affect the report as well. However, you can customize the visualization settings for the dashboard panel without affecting the report. References: Splunk Core User Certification Exam Study Guide, page 37.

This is the correct answer because these two filters can help you limit the amount of data that Splunk retrieves from disk, which is the key to fast searching1. The _time filter allows you to specify a narrow time window for your search, which reduces the number of buckets that Splunk scans2. The index filter allows you to specify which index or indexes contain the data that you want to search, which reduces the number of files that Splunk reads3.

The Kusto Query Language (KQL) is the language you use to query data in Azure Data Explorer [1]. It's a powerful language that allows you to perform advanced queries and extract meaningful insights from your data.

To query for events that match the criteria you specified, you would use the following KQL query:

index==main NOT status==200

This query will return all events that are inside the main index and have a status field, but the value of the status field does not equal 200. It is important to note that the "NOT" operator must be used in order to exclude events with a status value of 200.

By using the "NOT" operator, the query will return only events that do not match the specified criteria. This is useful for narrowing down search results to only those events that are relevant to the query.

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 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.
