Splunk is a software platform that specializes in collecting, analyzing, and visualizing machine-generated data from various sources like websites, applications, databases, networks, and devices. Splunk enables organizations to gather operational intelligence, analyze system performance, troubleshoot issues, and improve security.

Question 2

What are Splunk Forwarders?

Accepted Answer

Splunk Forwarders are lightweight agents that you install on source systems to collect and forward data to your Splunk deployment (like Splunk Enterprise or Splunk Cloud). These forwarders ensure minimal processing and impact on the source system while optimizing the transmission of data to the Splunk platform.

Question 3

What is the difference between Splunk Enterprise and Splunk Cloud?

Accepted Answer

Splunk Enterprise is an on-premise version of the Splunk platform that can be installed and managed by organizations within their own data centers or infrastructure. Splunk Cloud, on the other hand, is a fully managed, cloud-based service that offers the same functionality as Splunk Enterprise but is hosted and maintained by Splunk.

Question 4

What is the Splunk Common Information Model (CIM)?

Accepted Answer

The Splunk Common Information Model (CIM) is a shared knowledge base containing standardized field names, tags, and event types. It allows for easier data correlation and communication between users by providing a consistent structure and format for data that's ingested into the Splunk platform.

Question 5

How does Splunk handle data retention?

Accepted Answer

Splunk handles data retention through indexing and bucketing, which help manage data lifecycle and storage. Data ingested into Splunk passes through three stages - Hot, Warm, and Cold buckets, depending on the age and modification state of the data. Eventually, when the data meets the retention criteria, such as age or storage limits, it moves to the Frozen stage, where it can be deleted or archived as per the organization's needs.
