A backup component already installed and ready to take over automatically when the primary fails is a

• A. Warm Site
• B. Hot Site
• C. Cold Spare
• D. Hot Spare

Answer: (D)

This question tests the idea of standby components designed for immediate automatic failover. A backup component that’s already installed and configured to take over instantly when the primary fails is a hot spare. It’s kept ready to operate without manual intervention, minimizing downtime and keeping services available. Other options describe broader recovery approaches: a hot site is a full backup facility ready to run but not just a single component; a warm site has infrastructure ready but isn’t fully online yet and may require some steps to start; a cold spare is an unused item that would need setup before it can be used.
