A company has been given a Class C address to be utilized for all devices. The company has several
subnets and the largest subnet has 15 hosts. Which of the following represents the MINIMUM CIDR
notation of this subnet mask?
A.
/26
B.
/27
C.
/28
D.
/29
The answer should be /28 because, if we use /27 the largest subnet will have 31 hosts.
/28 255.255.255.240 you gonna get 16 address and 14 host; 2 will be excluded for network id and broad cast, but /27 255.255.255.224 you gonna get 32 address and 30 host which is lowest cidr
You are right!
