What is baseline configuration?

Baseline configuration refers to a defined state of a device that serves as a reference point for any subsequent changes. This state includes all the necessary settings, software versions, and security configurations that have been deemed optimal for the device's operation. Establishing a baseline configuration is critical because it provides a clear standard against which future modifications can be measured.

When adjustments or updates are made to a device, comparing the current configuration to the baseline allows administrators to evaluate the impact of such changes. This practice is essential for ensuring stability, security, and compliance in IT environments. By having a well-documented baseline, organizations can implement changes systematically, roll back to the baseline if issues arise, and maintain control over their device configurations throughout their lifecycle.

In contrast, the other options do not accurately define baseline configuration. For example, a temporary state used during software testing is not stable enough to serve as a reference point, a list of possible future upgrades does not relate to the current state of a device, and configuring a device for the first time represents a starting point rather than an established reference.
