Which two of the following Class B IPv4 networks are reserved by IANA for private address assignment and private routing?
(Choose two)
A. 128.0.0.0
B. 169.16.0.0
C. 169.254.0.0
D. 172.16.0.0
E. 172.20.0.0
Correct Answer: DE
Explanation/Reference:
172.16.0.0/16 172.31.0.0/16 Class B addresses are reserved for both private assignment and routing.
169.254.0.0/16 is an APIPA address, and used only locally (see http://tools.ietf.org/html/rfc3927)
169.16/16 and 128.0/16 are public IPv4 addresses and should not be used for internal routing.
