A. B. C. D.D.
The correct answer is A. Backout plan.
Explanation:
A firmware upgrade is a process of updating the software instructions that control the hardware components of a device. During the firmware upgrade, it is essential to take precautions to avoid power outages or other unexpected events that can cause failure or corruption of the firmware. However, sometimes, despite taking precautions, unforeseen events can occur, such as a power outage.
In the event of a firmware upgrade failure, the organization needs to revert back to the most recent version of the firmware. This process is known as a backout plan. A backout plan is a pre-defined set of procedures that help to return the system to the previous state before the upgrade.
A backout plan usually includes a set of steps to follow, such as identifying the cause of the failure, notifying the relevant parties, identifying the most recent version of the firmware, and executing the procedure to return the system to the previous state.
A contingency plan is a plan that defines a set of procedures to follow in the event of an unexpected event, such as a power outage. However, a contingency plan is not specifically designed to handle the failure of a firmware upgrade.
An alternative plan is a plan that defines a different course of action to take when the original plan is not feasible. However, an alternative plan is not specifically designed to handle the failure of a firmware upgrade.
A backup plan is a plan that defines a set of procedures to follow to recover from a data loss event, such as a system crash or hardware failure. However, a backup plan is not specifically designed to handle the failure of a firmware upgrade.
Therefore, the most appropriate plan to implement to revert back to the most recent version of the firmware in the event of a failure during the upgrade is a backout plan.
