Networking ConceptsCâu 6 / 100
How many usable host addresses are available in a subnet with a /29 prefix?
a.2
b.4
c.6
d.8
Giải thích
A /29 leaves 3 host bits, giving 2^3 = 8 total addresses, minus the network and broadcast addresses, for 6 usable hosts. Subnetting math requires subtracting two reserved addresses from the total. /29 subnets are common for small point-to-point or device segments.
