1.3-2 Packet switching versus circuit switching (1).  Which of the characteristics below are associated with the technique of packet switching? Select all correct answers. [Hint: more than one of the answers is correct].Group of answer choicesThis technique is used in the Internet.Resources are used on demand, not reserved in advance.Reserves resources needed for a call from source to destination.Data may be queued before being transmitted due to other user’s data that’s also queueing for transmission.Frequency Division Multiplexing (FDM) and Time Division Multiplexing (TDM) are two approaches for implementing this technique.This technique was the basis for the telephone call switching during the 20th century and into the beginning of this current century.Congestion loss and variable end-end delays are possible with this technique.

Which statement is correct about Ethernet switch frame forwarding decisions?Frame forwarding decisions are based on MAC address and port mappings in the CAM table.Cut-through frame forwarding ensures that invalid frames are always dropped.Unicast frames are always forwarded regardless of the destination MAC address.Only frames with a broadcast destination address are forwarded out all active switch ports.

How does a switch help improve Ethernet performance A. By restricting broadcast traffic B. By replacing hubs as mainstream devices C. By confining collisions to a particular scope D. By improving data link layer communication

For which three reasons was a packet-switched connectionless data communications technology used when developing the Internet? (Choose three.)Group of answer choicesIt can rapidly adapt to the loss of data transmission facilities.It efficiently utilizes the network infrastructure to transfer data.Data packets can travel multiple paths through the network simultaneously.It allows for billing of network use by the amount of time a connection is established.It requires that a data circuit between the source and destination be established before data can be transferred.
