A. Physical Layer
B. Datalink Layer
C. Network Layer
D. Session Layer
E. Transport Layer
F. Presentation Layer
G. Application Layer
A,B 解析：Explanation:
A WAN is a data communications network that covers a relatively broad geographic area and that often uses transmission facilities provided by common carriers, such as telephone companies. WAN technologies generally function at the lower two layers of the OSI reference model: the physical layer and the data link layer as shown below.
Note: Occasionally WAN's would also be considered to operate at layer 3, but since this question asked for only 2 chopices layers 1 and 2 are better choices.
