Which term is associated with detecting and reacting to component failures and is sometimes linked with RAID arrays?

• A. Self-Healing Hardware
• B. FPGA
• C. SoC
• D. Serverless Computing

Answer: (A)

This question tests fault tolerance and automated recovery in hardware. Self-healing hardware describes systems that can detect component faults and take corrective actions automatically, keeping the system running with minimal or no manual intervention. In storage setups, this often includes mechanisms to maintain availability by rebuilding data onto redundant paths or spare drives, such as rebuilding a RAID array when a disk fails. That automatic detection and recovery is the essence of self-healing hardware, and it’s why it’s the best fit for describing detection of failures and automated reaction in a way that can tie into RAID behavior.

The other terms don’t capture this behavior. A field-programmable gate array is about configurable logic circuits, not automatic, ongoing fault detection and recovery. A system on a chip combines components on one chip but isn’t defined by fault-management behavior. Serverless computing focuses on abstracting away server management for the user, not on hardware self-recovery mechanisms.
