A systems administrator plans to upgrade a server to the latest operating system. Which of the following should the administrator do before placing a change request?

Establishing a scope defines the boundaries of the change, including which systems are affected, the resources required, the timeline, and the potential impact, which is essential information needed before formalizing a change request and seeking approval. This foundational step helps justify the change to the change board.

Getting change board approval is a step that follows the creation and submission of a change request, not something done before placing the request.

Creating a test environment is an important step in the change management process, typically occurring after the scope is defined and often before or in parallel with formal approval, but defining the scope must precede it.

Rolling back previous changes is a corrective action taken if a recent change causes issues, which is irrelevant to the initial planning phase of a new upgrade.
