Which dotted-decimal mask represents a /26 subnet?

Explanation:
Subnet masks are defined by the number of 1 bits in the 32-bit mask. A /26 has 26 ones. In binary that’s 11111111.11111111.11111111.11000000. Converting to dotted decimal gives 255.255.255.192—the first three octets are all 1s (255 each), and the last octet has the top two bits set (11000000), which equals 192. The remaining options map to /24 (255.255.255.0), /16 (255.255.0.0), and /8 (255.0.0.0), respectively.
