Which term describes systems designed to increase reliability by providing alternative options in case of failure?

• A. Simulation Based Acquisition
• B. Redundant back-up systems
• C. Decentralize staff functions
• D. Source selection

Answer: (B)

Redundancy is the design strategy that adds backups so operations continue if a part of the system fails. By providing alternative options in case of failure, the system can switch to a standby component without interrupting service, boosting reliability. Examples include redundant power supplies, duplicate servers, data replicas, or alternate communication links that automatically take over. The other concepts describe different ideas: modeling approaches for procurement decisions, reorganizing how staff perform tasks, and methods for choosing suppliers. Redundancy specifically means having backup options ready to maintain performance, which is why it best fits the description.
