Which AFC color indicates Offline status?

• A. Green
• B. Yellow
• C. Gray
• D. Red

Answer: (C)

In AFC systems, status colors are used so staff can quickly understand a device’s condition. When a device is not connected or not available to process transactions, gray is used to signal that it’s inactive or offline. This neutral color contrasts with the others to clearly show it’s not currently in service. Green, by contrast, means online and functioning; yellow typically signals a warning or attention needed while still being accessible; red denotes a fault or critical issue requiring immediate action. So gray is the best indicator of Offline status because it communicates inactivity or unavailability at a glance.
