Correct Answer: B
Section: Network architecture

Explanation:
An IPv4 address is notated as four decimal numbers each between 0 and 255 separated by dots (xxx.xxx.xxx.xxx). Each number is known as an octet as it represents eight binary bits. All four octets make up a 32-bit binary IPv4 address.
In this question, 192.168.1.254 is a valid IPv4 address.
