Which of the following accurately describes the meaning of redundant cooling?
The correct answer is D. A second cooling system in case of a failure. Redundant cooling refers to a system design where a backup cooling mechanism is in place to automatically take over if the primary cooling system fails.

Why each option
Redundant cooling refers to a system design where a backup cooling mechanism is in place to automatically take over if the primary cooling system fails.
This describes a specific application of cooling for a RAID system, not the general concept of redundancy.
This describes a cooling component within a redundant power supply, not the overall concept of redundant cooling.
This implies a cooling system that can be installed *after* a failure occurs, which is not true redundancy; true redundancy means the backup is already in place and ready to activate.
Redundancy in IT systems means having duplicate components or systems that can immediately take over operations if the primary component fails. A second cooling system provides fault tolerance, ensuring continuous operation and preventing overheating in case the first system malfunctions or stops working.
