Explanation
Option B is correct because the MTU (Main Transfer Unit) board in the U1900 system does not support hot swap - removing or replacing it while the system is running is unsupported and can cause service interruption or system instability. Hot swap requires the hardware and firmware to be specifically designed to handle board removal and insertion without disrupting power, signaling, or data traffic, and the MTU board lacks this capability.
Option A is wrong because it incorrectly assumes all boards in the U1900 platform support hot swap; in reality, hot swap support varies by board type, and the MTU is explicitly excluded.
Memory tip: Think "MTU = Must Take Unit offline." If a board name sounds foundational or central to system operation (like a main transfer unit), it typically cannot be swapped live - shutting down first is required to protect the system.
