In the DoD reference model, which layer conforms to the OSI transport layer?

A.
Process/Application Layer

B.
Internet Layer

C.
Host-to-Host Layer

D.
Network Access Layer

Explanation:
In the DoD reference model, the Host-to-Host layer parallels the function of the OSI’s transport
layer. This layer contains the Transmission Control Protocol (TCP), and the User Datagram Protocol
(UDP). * the DoD Process/Application layer, corresponds to the OSI’s top three layers, the
Application, Presentation, and Session layers. *The DoD Internet layer corresponds to the OSI’s
Network layer. * the DoD Network Access Layer, is the equivalent of the Data Link and Physical
layers of the OSI model. Source: MCSE:TCP/IP Study Guide by Todd Lammle, Monica Lammle, and
