Before deploying Splunk, it is important to gather some information about the current environment,

such as:

Overall goals for the deployment: This includes the business objectives, the use cases, the expected

outcomes, and the success criteria for the Splunk deployment. This information helps to define the

scope, the requirements, the design, and the validation of the Splunk solution1.

Key users: This includes the roles, the responsibilities, the expectations, and the needs of the

different types of users who will interact with the Splunk deployment, such as administrators,

analysts, developers, and end users. This information helps to determine the user access, the user

experience, the user training, and the user feedback for the Splunk solution1.

Data sources: This includes the types, the formats, the volumes, the locations, and the characteristics

of the data that will be ingested, indexed, and searched by the Splunk deployment. This information

helps to estimate the data throughput, the data retention, the data quality, and the data analysis for

the Splunk solution1.

Option B, C, and D are the correct answers because they reflect the essential information that is

needed before deploying Splunk. Option A is incorrect because the list of vendors for network

devices is not a relevant information for the Splunk deployment. The network devices may be part of

the data sources, but the vendors are not important for the Splunk solution.
