A hub or repeater is a layer _ device. - Layer 1 A Repeater is a Physical Layer Device and has no logic at all. It just repeats all signals. A packet that is sent using UDP which is a protocol at the transport layer, may or may not arrive at it's source and therefore is considered efficient but unreliable. - True An ARP request maps - IP address to a MAC address or layer 2 to layer 3 Correct ARP maps an IP to a MAC An Ethernet switch builds a table at the network layer (Layer 3) of the O...
