Solution

The network 172.16.0.0/20 provides 16 subnets and 4094 hosts.

Here's how:

The /20 in the IP address means that the first 20 bits are used for the network address leaving 12 bits for host addresses.

  1. Calculate the number of subnets: 2^(number of borrowed bits). In this case, we have borrowed 4 bits (as the default subnet mask for class B IP address is /16 and we have /20), so the number of subnets is 2^4 = 16.

  2. Calculate the number of hosts: 2^(number of host bits) - 2 (subtract 2 for the network address and broadcast address). In this case, we have 12 host bits, so the number of hosts is 2^12 - 2 = 4094.

So, the correct answer is "16 subnets and 4094 hosts".
