• A. High Availability
• B. Load Balancing
• C. Fault Tolerance
• D. SPOF

Answer: (C)

Fault tolerance is the ability of a system to keep operating even when components fail, by using redundant elements and seamless failover. When you have duplicate hardware, extra power supplies, and multiple network paths, the system can switch to backups without interrupting services if any one part fails. This design keeps operations running and minimizes disruption, which is exactly what these measures are aiming to achieve. While high availability also seeks to keep services up, fault tolerance emphasizes continuous operation through automatic, transparent recovery. Load balancing distributes work to prevent overload, but it doesn’t inherently ensure continued operation if a component fails. Eliminating a single point of failure is a key step toward fault tolerance.
