Splunk MCQ Quiz Questions And Answers

Splunk requires an agent to forward the data because the agent is responsible for collecting and sending the data from various sources to the Splunk indexer. The agent, also known as a forwarder, ensures that the data is properly indexed and searchable within the Splunk platform. Without the agent, Splunk would not be able to efficiently gather and process data from different systems and applications. Therefore, it is true that Splunk requires an agent to forward the data.

Splunk is a powerful software platform used for searching, analyzing, and visualizing machine-generated data. It is designed to handle unstructured data, which refers to data that does not have a predefined data model or organization. With Splunk, users can ingest and analyze various types of unstructured data, such as log files, social media feeds, sensor data, and more. Therefore, the statement that "you can read unstructured data in Splunk" is true, as Splunk is specifically built to handle and make sense of unstructured data.

By default, when you install Splunk in your localhost and add inputs, the data is stored in the "main" index. The "_internal" index is used for storing internal logs and metrics related to the Splunk system itself. Therefore, the correct answer is "Index=main".

The correct answer is "splunk clean eventdata -index _fishbucket". This command allows you to force a Splunk instance to reindex a file that has already been indexed. By running this command, you can clear the indexed data for a specific index, in this case, "_fishbucket", and then Splunk will reindex the file when it encounters it again. This is a manual process that allows you to selectively reindex specific files without deleting the entire index or creating a new one.

Splunk does not require a database (DB) to store data. Splunk is a software platform that allows organizations to analyze and visualize machine-generated data. It uses its own proprietary indexing and search technology to efficiently store and retrieve data without the need for a traditional database. This allows Splunk to handle large volumes of data in real-time and provides fast and flexible searching capabilities. Therefore, the correct answer is False.

To increase the size of the Splunk data storage, we can add more space to the index and also add more indexers. Adding more space to the index allows for storing more data within the existing index, while adding more indexers increases the overall capacity and performance of the Splunk system. By doing both, we can effectively expand the storage capabilities of Splunk and accommodate larger amounts of data.

Splunk allows for the backup and restoration of data through various methods depending on the specific requirements. When considering Splunk data, backup and restore options are essential for both the forwarder and indexer data, as well as for the search head data.Forwarders in Splunk collect and send data to indexers, while indexers process and store data. Backing up the indexer data is critical because it contains the actual indexed data.Search heads are the interface through which users query Splunk data and create dashboards and reports. Backing up the search head data ensures the preservation of knowledge objects like reports, alerts, and dashboards.Therefore, the most comprehensive approach to backing up and restoring Splunk data would involve both forwarder and indexer data, as well as search head data, making Both (b) and (c) the correct answer.

When you customize the user interface (UI) in your local version of Splunk and then upgrade to a new version, your customized UI will not remain the same. Upgrades to the Splunk version usually involve changes to the UI, which can result in the loss or modification of any customizations made in the previous version. Therefore, the statement that the customized UI will remain the same after an upgrade is false.

The correct answer is Splunkd and SplunkWeb. Splunkd is the main background process in Splunk that handles data indexing, searching, and storage. It is responsible for ingesting and processing data from various sources. SplunkWeb, on the other hand, is the web interface of Splunk that allows users to interact with the Splunk platform, perform searches, create visualizations, and manage the system. Together, these two processes form the backbone of Splunk's functionality, making them the main background processes in the platform.
