A user has no network connectivity. A check of the associated port indicates that the interface is
up, the line protocol is down. Which item would most likely cause this problem?
A.
Speed mismatch
B.
Incorrect encapsulation
C.
MTU set too low
D.
Duplex mismatch
Explanation:
If there is duplex mismatch, there will be connectivity, but there will be errors and late collisions.
Incorrect encapsulation – This is a user connectivity, so it is an ethernet connection, no
encapsulation configuration.
If MTU is different on each device or too low, there might problems in data transfer but the line
protocol will not go down
