Answer:
Speed Mismatch
Step-by-step explanation:
The full form of MDIX is Medium Dependent Interface Crossover. It is a 8C8P port connection that is often found on a computer system or a router. It describes the interface of computer network to the physical medium from a physical layer implementation.
In the context, a technician while working on a layer 2 issue sees that there are two switches that supports the MDIX. They are also connected through a crossover cable.
The issue is due to the difference in the speed that they are not matching so the they are unable to communicate with each other.
