Final answer:
Implementing change management can be an effective method of configuration management using a baseline.
Step-by-step explanation:
The effective method of configuration management using a baseline among the given options is implementing change management.
Change management involves implementing a structured approach to manage changes to a system's configuration. It helps ensure that changes are thoroughly evaluated, approved, and implemented in a controlled manner, which helps maintain stability and accountability in the system's configuration.
Other options, such as using images, implementing vulnerability management, and implementing patch management, are also important aspects of configuration management, but they may not necessarily involve the use of a baseline.
