Explanation

Redundancy addresses the root cause by eliminating single points of failure. In this context, redundancy solutions include Uninterruptible Power Supplies (UPS) or generators to provide continuous power during outages, redundant power supply units within the server, and RAID storage arrays to prevent data loss if a drive fails. Recovery procedures are reactive - they help after data is already lost. EMI shielding protects against electromagnetic interference, not power outages. Environmental monitoring detects conditions like temperature or humidity but does not prevent power loss. Redundancy is the proactive, preventive control that keeps the server operational through an outage.
