A. B. C. D.D
To calculate the number of subnets that can be created from a given IP address range, we need to use the formula:
Number of subnets = 2^(number of subnet bits)
In this case, we have been assigned a /24 network, which means we have 24 bits for the network portion and 8 bits for the host portion.
We need to segment this network into at least 60 subnets, which means we need to find a subnet mask that will give us at least 60 subnets.
To determine which subnet mask will meet this requirement, we need to find the number of subnet bits required to create at least 60 subnets.
Number of subnets = 2^(number of subnet bits) 60 = 2^(number of subnet bits)
Taking the log of both sides, we get:
log2(60) = number of subnet bits
number of subnet bits = 5.91
Since we can only use whole numbers for the number of subnet bits, we need to round up to 6.
So, we need at least 6 subnet bits to create 60 subnets.
To determine the subnet mask, we add the 6 subnet bits to the existing 24 network bits, which gives us a total of 30 bits for the network portion.
Therefore, the subnet mask that meets the requirement of segmenting the /24 network into at least 60 subnets is /30.
Option D, /30, is the correct answer.
