At which OSI layer is a logical path created between two host systems named TK1
and TK2 on the TestKing LAN?
A. Physical
B. Session
C. Data link
D. Transport
E. Network
F. Application
G. Presentation

Answer: E
Explanation:
The Network layer (also called layer 3) manages device addressing, tracks the location of
devices on the network, and determines the best way to move data, which means that the
Network layer must transport traffic between devices that aren't locally attached. Routers
(layer 3 devices) are specified at the Network layer and provide the routing services
within an internetwork.
