Explanation: Users log on to the search head and run reports: – The search head dispatches searches to the peers – Peers run searches in parallel and return their portion of results – The search head consolidates the individual results and prepares reports.

Explanation: https://docs.splunk.com/Documentation/Splunk/8.1.1/Updating/Definedeploymentclasses# Ways_to_define_server_classes "When you use forwarder management to create a new server class, it saves the server class definition in a copy of serverclass.conf under $SPLUNK_HOME/etc/system/local. If, instead of using forwarder management, you decide to directly edit serverclass.conf, it is recommended that you create the serverclass.conf file in that same directory, $SPLUNK_HOME/etc/system/local."

Explanation: A role in Splunk is a classification that determines what capabilities and indexes a user has.A capability is a permission to perform a specific action or access a specific feature on the Splunk platform1.An index is a collection of data that Splunk software processes and stores2. By assigning roles to users, you can control what they can do and what data they can access on the Splunk platform.

Therefore, the correct answers are A and D. A role in Splunk determines what capabilities and indexes a user has. Option B is incorrect because Splunk servers do not use roles to remotely control each other.Option C is incorrect because Splunk servers use instances and components to determine what functions they control.

Explanation: According to the Splunk documentation1, a heavy forwarder is a Splunk Enterprise instance that can parse and filter data before forwarding it to an indexer. A heavy forwarder can perform line breaking, which is the process of splitting incoming data into individual events based on a set of rules2. A heavy forwarder can also apply other transformations to the data, such as field extractions, event type matching, or masking sensitive data.

"You can collect data on the universal forwarder using several methods. Define inputs on the universal forwarder with the CLI. You can use the CLI to define inputs on the universal forwarder. After you define the inputs, the universal forwarder collects data based on those definitions as long as it has access to the data that you want to monitor. Define inputs on the universal forwarder with configuration files. If the input you want to configure does not have a CLI argument for it, you can configure inputs with configuration files. Create an inputs.conf file in the directory, $SPLUNK_HOME/etc/system/local

The fastest way to add data to your Splunk Cloud instance or Splunk Enterprise deployment is to use Splunk Web. After you access the Add Data page, choose one of three options for getting data into your Splunk platform deployment with Splunk Web:

(1) Upload
(2) Monitor
(3) Forward The Upload option lets you upload a file or archive of files for indexing.
When you choose Upload option, Splunk Web opens the upload processpage. Monitor. For Splunk Enterprise installations, the Monitor option lets you monitor one or more files, directories, network streams, scripts, Event Logs (on Windows hosts only), performance metrics, or any other type of machine data that the Splunk Enterprise instance has access to.

Explanation:

The answer to your question is C. services/data/collector. This is the endpoint URI used to collect data in a customer managed Splunk Enterprise environment.According to the Splunk documentation1, “The HTTP Event Collector REST API endpoint is /services/data/collector.You can use this endpoint to send events to HTTP Event Collector on a Splunk Enterprise or Splunk Cloud Platform deployment.” You can also use this endpoint to send events to a specific token or index1. For example, you can use thefollowing curl command to send an event with the token 578254cc-05f5-46b5-957b-910d1400341a and the index main: curl -https://localhost:8088/services/data/collector -H'Authorization: Splunk 578254cc-05f5-46b5-957b-910d1400341a'-d'{"index":"main","event":"Hello, world!"}'

Explanation:

Begin generating internal Splunk logs. Immediately after installation, a Universal Forwarder will start generating internal Splunk logs that contain information about its own operation, such as startup and shutdown events, configuration changes, data ingestion, and forwarding activities1. These logs are stored in the $SPLUNK_HOME/var/log/splunk directory on the Universal Forwarder machine2.
