After accommodating each department, identify the unused portion of the subnet by responding to the question on the graphic. All drop downs must be filled. If at any time you would like to bring

Explanation: Sales network - /26 - This will provide up to 62 usable IP addresses (64-2 for subnet and broadcast IP) HR network - /27 - This will provide for up to 30usable IP's (32-2) IT - /28 - This will provide for up to 14 usable IP's (16-2) Finance - /26 - Note that a /27 is 32 IP addresses but 2 of those are reserved for the network and broadcast IP's and can't be used for hosts. Marketing - /28 If we add up how many IP blocks are used that is 64+32+16+64+16=192. A /24 contains 256 IP addresses, so 256-192=64.
