To calculate the most efficient subnet for 31 devices, consider subnet sizes and available host addresses. A /27 subnet provides 32 addresses, but 2 are reserved (network and broadcast addresses), leaving 30 usable, which is insufficient. A /26 subnet offers 64 addresses, with 62 usable, sufficient for 31 devices. Thus, the best choice is 10.10.10.0/26.
Should be 10.10.10.0/26 (64IPs - 2 = 62 usable) 10.10.10.0/27 is 32 IPs - 2 = 30 usable. We need to fit 31 IPs therefore it should be /26. Correct me if I am wrong.
/26 gives us 64 minus 2 for BR and Net ID 62 /27 is to few 32 minus 2 = 30
We need 31 hosts. /27 = 32 hosts BUT 2 are reserved for network and broadcast addresses (30 hosts) . /26 is the right answer (62 hosts)
C is correct, easy
C is the answer
