What mechanism is commonly used to maintain CRC data processing availability?

• A. Automatic failover mechanisms
• B. Manual reboot only
• C. Data loss during outages
• D. Reducing data fidelity to avoid faults

Answer: (A)

Automatic failover mechanisms keep CRC data processing available by always having a ready standby system that can take over the moment the active system fails. The two systems run in parallel with synchronized data and state, and they continually exchange heartbeat signals to confirm everything is healthy. If a fault is detected, the standby is automatically promoted to active, and data flows are redirected without waiting for a human to intervene. This rapid switch minimizes downtime and keeps critical C2 processing up and running, which is essential in environments where every second counts.

Manual reboot would introduce delays while waiting for someone to act. Data loss during outages is the problem we aim to prevent, not a mechanism to maintain availability. Reducing data fidelity to avoid faults would undermine the quality and usefulness of the information, not protect availability.
