Which Open Systems Interconnection (OSI) layer(s) BEST corresponds to the network access layer in the Transmission Control Protocol/Internet Protocol (TCP/ IP) model?
The answer is -A-
Hardware (Lower layers) - Physical, Data Link, Network
Heart of OSI - Transport
Sofware (Upper layers) - Session, Presentation, Application
Answer is A.
Osi Model - TCP/IP model
Application, presentation, session = Application layer
Transport =Transport
Network=Internet
Data link, physical = Network access layer
As a CCNA and network analyst, how inthe world did you guys come up with A as the right answer? Data link and Physical layer has absolutely nithing to do with the network layer. Clearly the answer has to be B. WOW!
The correct answer is A.
Very tricky question: It does not say "Network" Layer, instead there is a mention of "Network Access" - Which is basically a combination of Physical and Data Links from OSI model and the Network Interface Layer of TCP/IP model.
