Splunk Updated SPLK-1005 Exam Questions and Answers by arla

In Splunk, an index is a data repository that stores both raw data and associated indexing information. Specifically, the raw data is stored in a compressed format, and the indexing information is stored in tsidx files (time series index files). These tsidx files enable fast searching and retrieval of data based on time. The correct terminology and structure make option B accurate.

Option B is the correct approach because it properly uses a TRANSFORMS stanza in props.conf to reference the transforms.conf for removing sensitive data. The transforms stanza in transforms.conf uses a regular expression (REGEX) to locate the sensitive data (in this case, the SuperSecretNumber) and replaces it with a masked version using the FORMAT directive.

In detail:

props.conf refers to the transforms.conf stanza remove_sensitive_data by setting TRANSFORMS-cleanup = remove_sensitive_data.

transforms.conf defines the regular expression that matches the sensitive data and specifies how the sensitive data should be replaced in the FORMAT directive.

This approach ensures that sensitive information is masked before indexing without altering the structure of the log files.

Splunk Cloud Reference: For further reference, you can look at Splunk's documentation regarding data masking and transformation through props.conf and transforms.conf.

When dealing with a directory containing a mix of file types, it's essential to fine-tune the sourcetypes for different files to ensure accurate data parsing and indexing.

B. On the forwarder collecting the data, leave sourcetype as automatic for the directory monitor. Then create a props.conf that assigns a specific sourcetype by source stanza: This is the correct answer. In this approach, the Universal Forwarder is set up with a directory monitor where the sourcetype is initially left as automatic. Then, a props.conf file is configured to specify different sourcetypes based on the source (filename or path). This ensures that as the data is collected, it is appropriately categorized by sourcetype according to the file type.

Splunk executes scripts from specific directories that are structured within its installation paths. These directories typically include:

SPLUNK_HOME/etc/system/bin: This directory is used to store scripts that are part of the core Splunk system configuration.

SPLUNK_HOME/etc/apps/<app name>/bin: Each Splunk app can have its own bin directory where scripts specific to that app are stored.

SPLUNK_HOME/bin/scripts: This is a standard directory for storing scripts that may be globally accessible within Splunk's environment.

However, C. SPLUNKHOMS/ctc/scripts/local is not a recognized or standard path used by Splunk for executing scripts. This path does not adhere to the typical directory structure within the SPLUNK_HOME environment, making it the correct answer as it does not correspond to a valid script execution path in Splunk.
