SPLK-2002: Splunk Enterprise Certified ArchitectDemo

When documenting the current IT environment topology for a Splunk deployment, you need the information that shapes where and how Splunk components and data flows are placed: the authentication system(s) in place (A), the location of data centers (B), and any security restrictions between sites such as firewalls or bandwidth constraints (D). The type of hardware used for general network servers (C) is not part of the environment topology — it belongs to the separate data-source discovery step and does not affect Splunk placement decisions — so it is excluded. This matches the standard Splunk architect guidance keying the answer to A, B, and D.
