A.
That ISP then assigned this entire Class C network to one of its Asian customers.
Network 200.1.2.0/24 has yet to be assigned to any ISP. Which of the following is most likely

B.
200.1.2.0/24 will be assigned in the same geography (Asia) as 200.1.1.0/24.

C.
200.1.2.0/24 cannot be assigned as public address spacE.

D.
Routers inside North American ISPs increase their routing table size by 1 as a result of
the customer with 200.1.1.0/24 connecting to the Internet.

Explanation:
ICANN and IANA manage the assignment of public IPv4 address space such that large
address blocks (often called CIDR blocks) exist in a particular geography or are assigned to
particular ISPs. As such, Internet routers can more easily create summary routes to help
keep the routing table small in the Internet. 200.1.2.0/24 would likely also be allocated to
some registrar, ISP, or customer in AsiA. Because of the large route summaries, in this case
possibly a summary for 200.0.0.0/8, routers in North America would not see an increase in
the size of their routing tables.

that’s partially true for PA (provider assigned address space). For PI (provider independent) addresses, single address blocks not coming from an aggregate are common.
