You work as a network technician at TestKing.com. Please study the exhibit carefully. Based on the information shown above, what is needed to allow host TestKingl to ping host TestKing2?

A.    a crossover cable connecting the switches

B.    a backbone switch connecting the switches with either fiber optic or straight-through cables

C.    a straight-through cable connecting the switches

D.    a CSU/DSU connected to the switches with straight-through cables

E.    a router connected to the switches with straight-through cables

Answer: E Explanation:

Routers are Layers 3 devices used for inter-network communication. In this scenario there are two different networks, so both switches need to connect to a router using straight-through cables.

A straight-through cable is used to connect two different devices like, switch to router, host to switch. Since we need to insert a router for communication between the two switches, straight through cables will be used between the switches and the router.
