Multiple Choice

An IPv4 octet value can be 256.

Explanation:
IPv4 addresses are made of four octets, and each octet is 8 bits. An 8-bit value can represent 2^8 distinct numbers, which are 0 through 255. Because of that, 256 would require a ninth bit and cannot be stored in a single octet. Therefore an IPv4 octet value cannot be 256; any address with an octet of 256 would be invalid.
