The correct understanding of the requirements for fire-rated exterior walls is that they must be rated for exposure to fire from the outside when the fire separation distance exceeds 10 feet. This means that while the building may have a greater distance from neighboring properties or structures, it still needs to consider the potential for fires originating outside of its own boundaries.

Exterior walls primarily need to protect the building from external fire risks and ensure that any neighboring structures or hazards do not pose a threat to the integrity of the building. This is essential for maintaining safety and compliance with safety codes. Therefore, the focus is predominantly on exterior fire exposure rather than threats coming from the inside of the building.

Understanding this context is crucial for compliance with building codes, which aim to protect both the structure itself and the occupants by mitigating the risks associated with fire.
