Splunk SPLK-1003 Practice Test - Questions Answers, Page 16

This is explained in the Splunk documentation1, which states:

If an indexer goes down during a search, the search head notifies you that the results might be incomplete. The search head does not attempt to re-run the search on another indexer.

curl "https://mysplunkserver.example.com:8088/services/collector" \ -H "Authorization: Splunk DF4S7ZE4-3GS1-8SFS-E777-0284GG91PF67" \ -d '{"event": "Hello World"}, {"event": "Hola Mundo"}, {"event": "Hallo Welt"}'. This is the correct curl command to send multiple events through HTTP Event Collector (HEC), which is a token-based API that allows you to send data to Splunk Enterprise from any application that can make an HTTP request. The command has the following components:

The URL of the HEC endpoint, which consists of the protocol (https), the hostname or IP address of the Splunk server (mysplunkserver.example.com), the port number (8088), and the service name (services/collector).

The header that contains the authorization token, which is a unique identifier that grants access to the HEC endpoint. The token is prefixed with Splunk and enclosed in quotation marks. The token value (DF4S7ZE4-3GS1-8SFS-E777-0284GG91PF67) is an example and should be replaced with your own token value.

The data payload that contains the events to be sent, which are JSON objects enclosed in curly braces and separated by commas. Each event object has a mandatory field called event, which contains the raw data to be indexed. The event value can be a string, a number, a boolean, an array, or another JSON object. In this case, the event values are strings that say hello in different languages.

This is because the input type is UDP, which is an unreliable protocol that does not guarantee delivery, order, or integrity of the data packets. UDP does not have any mechanism to resend or acknowledge the data packets, so if Splunk is restarted, any data that was in transit or in the buffer may be dropped and not indexed.

... The ellipsis wildcard searches recursively through directories and any number of levels of subdirectories to find matches.

If you specify a folder separator (for example, //var/log/.../file), it does not match the first folder level, only subfolders.

* The asterisk wildcard matches anything in that specific folder path segment.

Unlike ..., * does not recurse through subfolders.

When using a directory monitor input, specific source types can be selectively overridden using the props.conf file.According to the Splunk documentation1, ''You can specify a source type for data based on its input and source. Specify source type for an input. You can assign the source type for data coming from a specific input, such as /var/log/. If you use Splunk Cloud Platform, use Splunk Web to define source types. If you use Splunk Enterprise, define source types in Splunk Web or by editing the inputs.conf configuration file.'' However, this method is not very granular and assigns the same source type to all data from an input.To override the source type on a per-event basis, you need to use the props.conf file and the transforms.conf file2.The props.conf file contains settings that determine how the Splunk platform processes incoming data, such as how to segment events, extract fields, and assign source types2.The transforms.conf file contains settings that modify or filter event data during indexing or search time2.You can use these files to create rules that match specific patterns in the event data and assign different source types accordingly2.For example, you can create a rule that assigns a source type of apache_error to any event that contains the word ''error'' in the first line2.

According to the Splunk documentation1, to customize a configuration file, you need to create a new file with the same name in a local or app directory. Then, add the specific settings that you want to customize to the local configuration file. Never change or copy the configuration files in the default directory. The files in the default directory must remain intact and in their original location. The Splunk Enterprise upgrade process overwrites the default directory.

To deploy configuration files to deployment clients, you need to use the deployment server.The deployment server is a Splunk Enterprise instance that distributes content and updates to deployment clients2.The deployment server uses a directory called $SPLUNK_HOME/etc/deployment-apps to store the apps and configuration files that it deploys to clients2.To update the configuration files in this directory, you need to edit them manually and then run the command $SPLUNK_HOME/bin/sp1unk reload deploy---server to make the changes take effect2.

Therefore, option A is incorrect because it does not include the reload command. Option B is incorrect because it makes the change on a deployment client instead of the deployment server. Option D is incorrect because it changes the default directory instead of the local directory.

The correct answer is B. in props.conf:

[identity]

SEDCMD-redact_pw = s/password=([^,|/s]+)/ ####REACTED####/g

According to the Splunk documentation1, to redact sensitive data from raw events, you need to use the SEDCMD attribute in the props.conf file. The SEDCMD attribute applies a sed expression to the raw data before indexing. The sed expression can use the s command to replace a pattern with a substitution string. For example, the following sed expression replaces any occurrence of password= followed by any characters until a comma, whitespace, or slash with ####REACTED####:

s/password=([^,|/s]+)/ ####REACTED####/g

The g flag at the end means that the replacement is applied globally, not just to the first match.

Option A is incorrect because it uses the REGEX attribute instead of the SEDCMD attribute. The REGEX attribute is used to extract fields from events, not to modify them.

Option C is incorrect because it uses the transforms.conf file instead of the props.conf file. The transforms.conf file is used to define transformations that can be applied to fields or events, such as lookups, evaluations, or replacements. However, these transformations are applied after indexing, not before.

Option D is incorrect because it uses both the wrong attribute and the wrong file. There is no REGEX-redact_pw attribute in the transforms.conf file.

According to the Splunk documentation1, to manually specify a character set for an input, you need to set the CHARSET key in the props.conf file. You can specify the character set by host, source, or sourcetype, but not by index.
