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...

DHCP - Dynamic Host Configuration Protocol is used to assign IP addresses automatically to clients on the network. The connectionless DHCP uses UDP port 67 for sending data to the server and UDP port 68 for sending data to the client. DHCP replaced an earlier protocol called BOOTP that functioned similarly. Port: 67 and 68 Transport Protocol: UDP DNS - Domain Name System maps computer names to IP addresses. TCP 53 is used for DNS zone transfers, whereas UDP 53 is used for DNS queries and ...
