Alcatel-Lucent NRS I Composite Exam — Question 14

The 201.148.26.0/24 network is subnetted using a /26 mask. How many subnets and host addresses will you obtain with this mask?

Answer options

• A. 4 subnets, 64 hosts
• B. 64 subnets, 4 hosts
• C. 4 subnets, 62 hosts
• D. 64 subnets, 2 hosts
• E. 6 subnets, 30 hosts

Correct answer: C

Explanation

Using a /26 subnet mask, the original /24 network is split into 4 subnets, as the subnetting increases the number of bits used for the subnet from 24 to 26. Each subnet has 64 IP addresses, but 2 are reserved (network and broadcast), leaving 62 usable host addresses per subnet, making option C correct while the others do not accurately represent the calculations.
