Question 45

How many subnets and host addresses are obtained by subnetting network 201.148.26.0/24 using a /26 subnet mask?

    Correct Answer: C

    Subnetting a /24 network with a /26 subnet mask results in 4 subnets, as each subnet is formed by borrowing 2 bits from the host portion (2^2 = 4). Each /26 subnet has 64 addresses (2^(32-26) = 64), but 2 addresses in each subnet are reserved (1 for the network address and 1 for the broadcast address), leaving 62 usable host addresses per subnet.

question doesn't specify usable host, so it could be 4-64

LungfulOption: C

C is the correct answer. 62 hosts.

It asked number of hosts for /26, it should be 64. Number of useable hosts is 62. IMHO, A is correct.
