What file extension identifies switch image files?

• A. .bin
• B. .img
• C. .exe
• D. .iso

Answer: (B)

Recognizing switch image files comes down to the type of image they represent. A switch image is a firmware package designed to be flashed onto the device, so the file extension should signal a complete image intended for the switch. The .img extension does exactly that by indicating a raw disk or firmware image that can be loaded onto the switch.

In contrast, a .bin file is a generic binary that could be anything and isn’t as clearly identified as a device image; a .exe is a Windows executable, not something used for firmware on switches; and a .iso is a disk image intended for creating optical media, which represents a different use case than a direct firmware image for a device.
