In the event of a disruption or disaster, which of the following technologies provides for continuous operations?

A. Load balancing

B. Fault-tolerant hardware

C. Distributed backups

D. High-availability computing

Explanation:

Fault-tolerant hardware is the only technology that currently supports continuous, uninterrupted service. Load balancing is used to improve the performance of the server by splitting the work between several servers based on workloads. High-availability (HA) computing facilities provide a quick but not continuous recovery, while distributed backups require longer recovery times.
