B.
Internet
C.
Network access
D.
Physical
Explanation:
The Internet Layer in the Internet Model maps to the Network Layer in the OSI model.
Functionality remains the same, so routing is done at this level.Incorrect Answers:
A: The transport layer works with host-to-host issues, and routing functions do not occur at this
level.
C: The Network Access layer maps to the Physical and Data Link layers of the OSI model. Routing
is not performed here.
D: There is no physical layer in the Internet Architecture model. The physical and data link layers
of the OSI model map to the network access layer. Routing does not occur here.
