A. B. C. D.B.
The correct answer is B. Change management.
Change management is a process that ensures that any changes made to a system are carefully planned, reviewed, tested, and implemented in a controlled manner. The process includes tracking and documenting all changes made to the system, including upgrades, to ensure that they are properly authorized, and to provide a historical record of changes made.
When reviewing previous upgrades to a system, the change management process would be the most likely method used to track and document the changes made. This process provides a clear audit trail of all changes, including who made the changes, when they were made, and why they were made. This information can be used to evaluate the success of past upgrades, identify areas for improvement, and plan future upgrades.
Business continuity plans are designed to ensure that critical business functions can continue in the event of a disruption, such as a natural disaster or cyberattack. While these plans may include information about system upgrades, they are not designed specifically to review previous upgrades.
System life cycle refers to the stages a system goes through from conception to retirement. This process includes planning, design, development, implementation, and maintenance. While system life cycle may involve reviewing upgrades made during the maintenance phase, it is not focused solely on reviewing previous upgrades.
Standard operating procedures (SOPs) are documents that outline the steps required to perform specific tasks or processes. While SOPs may include information about upgrading a system, they are not specifically designed to review previous upgrades.
