Which of the following uses classless subnet masks across a network?
A. Subnetting
B. CIDR
C. Supernetting
D. Summarization
Answer: B
Explanation:
Classless Inter-Domain Routing is based onvariable-length subnet masking(VLSM), which allows a network to be divided into variously sized subnets, providing the opportunity to size a network more appropriately for local needs and also CIDR allows an address or routing prefix to be written with a suffix indicating the number of bits of the prefix, such as 192.168.2.0/24.
