What is a configuration item in a system?

• A. This is an identifiable part of a system (e.g., hardware, software, firmware, documentation, or a combo thereof) that is a discrete target of configuration control processes.
• B. A user account
• C. A network service
• D. A security policy

Answer: (A)

Configuration management focuses on identifying and controlling components of a system. A configuration item is any identifiable part of the system that is a discrete target of configuration control, meaning it has its own identity, versioning, and change record in the process. This can include hardware, software, firmware, documentation, or a combination of these, all managed to maintain system integrity through approval, tracking, and baselining. While a user account, a network service, or a security policy are important elements in IT environments, they aren’t inherently defined as configuration items in the sense of being separate components that undergo controlled changes; they may be treated as configuration items in some contexts, but the core idea is about discrete system components under change control.
