In the graphic, Host A has reached 50% completion in sending a 1 KBEthernet frame to Host D when Host B wishes to transmit its own frame toHost C.
What must Host B do?Host B can transmit immediately since it is connected on its own cable segment.Host B must wait to receive a CSMA transmission from the hub, to signal its turn.Host B must send a request signal to Host A by transmitting an interframe gap.Host B must wait until it is certain that Host A has completed sending its frame.2.

Which of the following describe interframe spacing? (Choose two.)the minimum interval, measured in bit-times, that any station must wait beforesending another frame.the maximum interval, measured in bit-times, that any station must wait beforesending another frame.the 96-bit payload padding inserted into a frame to achieve a legal frame sizethe 96-bit frame padding transmitted between frames to achieve propersynchronizationthe time allowed for slow stations to process a frame and prepare for the nextframe.the maximum interval within which a station must send another frame to avoid beingconsidered unreachable4.
What three primary functions does data link layer encapsulation provide?(Choose three.)addressingerror detectionframe delimitingport identificationpath determinationIP address resolution5. When a collision occurs in a network using CSMA/CD, how do hosts withdata to transmit respond after the backoff period has expired?The hosts return to a listen-before-transmit mode. <--The hosts creating the collision have priority to send data.The hosts creating the collision retransmit the last 16 frames.The hosts extend their delay period to allow for rapid transmission.6. What are three functions of the upper data link sublayer in the OSImodel? (Choose three.)recognizes streams of bitsidentifies the network layer protocol.makes the connection with the upper layers.identifies the source and destination applicationsinsulates network layer protocols from changes in physical equipment.determines the source of a transmission when multiple devices are transmitting7.
