The CertKiller.com network currently has three departments and CertKiller.com plans to add a
fourth in the future. During the course of the day you receive instruction from CertKiller.com to
assign a subnet for the departments using the global address prefix 3FFA:FF2B:4D:B000::/41
assigned to you.
What should you do?
A. You should consider having the IPv6 address 3FFA:FF2B:4D:C000::/43 for the added
department.
B. You should consider having the IPv6 address 3FFA:FF2B:4D:F000::/45 for the added
department.
C. You should consider having the IPv6 address 3FFA:FF2B:4D:C800::/43 for the added
department.

Again.

E) none of the above.

or
 
F) any of the above

depending on how you read between the lines.

3ffa:ff2b:4d:b000::/52 describes all the addresses from 3ffa:ff2b:004d:b000:0000:0000:0000:0000 - 3ffa:ff2b:004d:bfff:ffff:ffff:ffff:ffff

3ffa:ff2b::/41 describes all the addresses from
3ffa:ff2b:0000:0000:0000:0000:0000:0000 - 3ffa:ff2b:007f:ffff:ffff:ffff:ffff:ffff

normal practice is to use the starting address when specifiying a block.

A) should be 3ffa:ff2b:40:0:0:0:0:0/43
B) should be 3ffa:ff2b:48:0:0:0:0:0/45
C) should be 3ffa:ff2b:40:0:0:0:0:0/43
D) should be 3ffa:ff2b:40:0:0:0:0:0/43

Since A, C & D are the same maybe B is the answer but who would really know.

Good luck!
