What are two reasons for physical layer protocols to use frame encoding techniques? (Choose two.) to identify where the frame starts and ends* to distinguish data bits from control bits* to reduce the number of collisions on the media to increase the media throughput to provide better media error correction
Which statement is correct about multimode fiber?

What is one main characteristic of the data link layer?
It converts a stream of data bits into a predefined code.
It shields the upper layer protocol from being aware of the physical medium to be used in the communication.*
It accepts Layer 3 packets and decides the path by which to forward a frame to a host on a remote network.
It generates the electrical or optical signals that represent the 1 and 0 on the media.
What is one advantage of using fiber optic cabling rather than copper cabling?
It is easier to terminate and install than copper cabling.
It is able to be installed around sharp bends.
It is usually cheaper than copper cabling.
It is able to carry signals much farther than copper cabling.*
