Right, A is the broadcast address - it is explained in better detail here: https://stackoverflow.com/questions/29034878/how-can-i-determine-network-and-broadcast-address-from-the-ip-address-and-subnet

There is typo in D; should be 255.255.255.252. Having said that, it's the correct answer.

The Answers B and C are out because their submask have the prefix /29, in A the 10.2.1.3 is the broadcast of 10.2.1.0 network. The answer correct is D because 209.165.201.2 is the 2nd available IP for 209.165.201.0 network.

Was there an instance in the actual exam wherein the choices are typographical errors? Because I chose A over D thinking that it was intentionally written as 225.

The answer is A, I saw some saying that A is a broadcast address and would like to remind everyone that broadcast addresses can be reconfigured while the mistake of having subnet mask 225.255.255.251 eliminates it as a candidate

D. interface e0/0 description to XX-AXXX:XXXXX ip address 209.165.201.2 225.255.255.252 Given address belongs to subnet 209.165.201.0/30, which ranges from 209.165.201.1 to 209.165.201.2.
