Free Practice Questions for Splunk SPLK-1003 Exam

The Data Preview feature should be used when validating the parsing of data. The Data Preview feature allows you to preview how Splunk software will index your data before you commit the data to an index. You can use the Data Preview feature to check the following aspects of data parsing1:

Timestamp recognition: You can verify that Splunk software correctly identifies the timestamps of your events and assigns them to the _time field.

Event breaking: You can verify that Splunk software correctly breaks your data stream into individual events based on the line breaker and should linemerge settings.

Source type assignment: You can verify that Splunk software correctly assigns a source type to your data based on the props.conf file settings. You can also manually override the source type if needed.

Field extraction: You can verify that Splunk software correctly extracts fields from your events based on the transforms.conf file settings. You can also use the Interactive Field Extractor (IFX) to create custom field extractions.

The Data Preview feature is available in Splunk Web under Settings > Data inputs > Data preview. You can access the Data Preview feature when you add a new input or edit an existing input1.

The other options are incorrect because:

A. When extracting fields for ingested data. The Data Preview feature can be used to verify the field extraction for data that has not been ingested yet, but not for data that has already been indexed. To extract fields from ingested data, you can use the IFX or the rex command in the Search app2.

B. When previewing the data before searching. The Data Preview feature does not allow you to search the data, but only to view how it will be indexed. To preview the data before searching, you can use the Search app and specify a time range or a sample ratio.

C. When reviewing data on the source host. The Data Preview feature does not access the data on the source host, but only the data that has been uploaded or monitored by Splunk software. To review data on the source host, you can use the Splunk Universal Forwarder or the Splunk Add-on for Unix and Linux.

When configuring multiple LDAP strategies in Splunk, the order in which they are listed in the authentication.conf file determines the sequence in which Splunk searches them during authentication.

From the official Splunk documentation:

" To configure multiple LDAP strategies, set the authSettings setting to a comma-separated list of all strategies, in the order in which you want to query the strategies. "

— Configure LDAP using configuration files - Splunk Documentation

Therefore, Splunk will search each LDAP strategy in the order specified in the authSettings parameter of the authentication.conf file.

Quoting the following Splunk URL reference https://docs.splunk.com/Documentation/Splunk/8.2.2/DMC/DMCprerequisites " Monitoring Console setup prerequisites. Forward internal logs (both $SPLUNK_HOME/car/log/splunk and $SPLUNK_HOME/var/log/introspection) to indexers from all other components. Without this step, many dashboards will lack data. "

https://docs.splunk.com/Documentation/Splunk/6.2.0/Data/Configuretimestamprecognition

" Specify how far (how many characters) into an event Splunk software should look for a timestamp. " since TIME_PREFIX = ^ and timestamp is from 0-29 position, so D=30 will pick up the WHOLE timestamp correctly.

Splunk checks role-to-group mapping only during user login for external authentication (e.g., LDAP, SAML). Users already logged in will continue using their previously assigned roles until they log out and log back in.

The changes to role mapping do not disrupt ongoing sessions.

Incorrect Options:

B:Search is not disabled upon role updates.

C:This is incorrect since existing users are also updated upon the next login.

D:Role updates do not terminate ongoing sessions.

When Splunk is integrated with LDAP, most of the user attributes are managed by the LDAP server and cannot be changed in the Splunk UI. However, one exception is the default app attribute, which specifies which app a user sees when they log in to Splunk. This attribute can be changed in the Splunk UI by editing the user settings. Therefore, option A is the correct answer. References: Splunk Enterprise Certified Admin | Splunk, [Configure Splunk to use LDAP and map groups - Splunk Documentation]

When a user is assignedmultiple rolesin Splunk and each has a defined srchFilter, Splunk combines these filters using alogical ANDoperation. This ensures that the user can only search within the intersection of constraints imposed by each role.

From Splunk Docs:

" If a user has multiple roles assigned and multiple roles specify srchFilter, Splunk softwareANDs the filters together. "

— Source: Splunk Documentation – authorize.conf

Let’s break it down:

role_A specifies: sourcetype!=json AND index=main

role_B specifies: sourcetype=csv

To evaluate the effective search filter for the user, Splunk willANDthe two conditions:

(sourcetype=csv) AND (sourcetype!=json AND index=main)

This means the user ' s search is limited to events where:

sourcetype=csv (from role_B)

sourcetype!=json AND index=main (from role_A)

Combining them together logically:

srchFilter = ((sourcetype=csv) AND (sourcetype!=json AND index=main))

This is exactly what is shown inOption A.
