Network Implementation第 37 / 100 题
An administrator assigns 192.168.1.0/24 but needs subnets of varying host sizes. Which technique allows different subnet mask lengths within the same address block?
a.CIDR summarization
b.Classful addressing
c.VLSM
d.APIPA
解析
Variable Length Subnet Masking (VLSM) lets an administrator apply different mask lengths to subnets within the same network, matching each subnet's host requirement. This conserves address space compared with fixed-size subnets. VLSM requires classless routing protocols.
