Which term describes a system design in which a component is duplicated so that if it fails there will be a backup?

• A. Order
• B. Redundancy
• C. Quote
• D. Conflated

Answer: (B)

Redundancy means duplicating components so a backup is available if one fails. This design choice keeps systems running even when part of the setup breaks, improving reliability and uptime. The backup can take over automatically through failover, so users notice minimal or no disruption. Redundancy can come in several forms: hot standby (the backup is active and ready to take over immediately), warm standby (backup is running but not fully active), or cold standby (backup is powered off until needed). This concept is the opposite of terms like order, which is a purchase request; quote, which is a price estimate; or conflated, which means blended or confused.
