Which statement is true about the replacement process?

• A. Reimage the register with new settings
• B. Secure all cables with zip ties
• C. Detach must be performed before replacement
• D. Power off all devices including the POS server

Answer: (C)

When performing a hardware replacement, the essential prerequisite is to detach the component from the system before removing or swapping it. This means unplugging cables and disconnecting the device so nothing is live or tugging on connections during the swap. Detaching first prevents electrical hazards, data integrity issues, and potential damage to other components, and it sets a safe stage for the replacement.

That’s why the statement about detaching before replacement is the best fit. Reimaging the register with new settings isn’t automatically part of every replacement—it’s something you do after the new part is in place if you need to apply new configurations. Securing cables with zip ties is good practice for organization but isn’t the critical step that defines the replacement process. Powering off devices is a safety measure, but the key action that must occur prior to replacement is detaching the device from the system.
