Q12. HOTSPOT
Corporate headquarters provided your office a portion of their class B subnet to use at a new office location. Allocate the minimum number of addresses (using CIDR notation) needed to accommodate each department.
Alter accommodating each department, identify the unused portion of the subnet by responding to the question on the graphic. All drop downs must be filled.
Instructions: When the simulation is complete, please select the Done button to submit.
All Networks have the range form /0 to/32
Answer:
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 30 usable 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.
So the last unused box should be a /26, which equates to 64 addresses
