An IT manager is concerned about server administrators having to be cross-trained to work on every server. Which of the following is the BEST way to correct this problem?

Server baselines are important for performance and security, but they do not provide the comprehensive operational details needed for an administrator to effectively work on an unfamiliar server.

Thorough and current server documentation, including configurations, network diagrams, and troubleshooting guides, enables any trained administrator to quickly understand and manage a server without needing specialized knowledge for every unique system. This approach centralizes knowledge, reducing the necessity for individual cross-training across a diverse server fleet.

KVM over IP provides remote access to servers but does not provide the administrative knowledge or context needed to manage a server effectively without prior experience or documentation.

Processing servers through a change control board is a process for managing modifications, not a solution for enabling administrators to work on any server without extensive individual training or documentation.
