What can computer A do to identify B's location and send data to it? (Select all that apply) Send a network layer (IP) broadcast message asking for the ARP table of Computer B Send a TCP Syn packet to Computer B's IP address Checkits own internal ARP table to find the MAC address of computer B Use the MAC translation list to find the location of computer B Which of the following statements are true for circuit switching? (Select all that apply) Setting up connection in circuit switching networks can take time Circuit switching is optimal for streams of data, rather than bursts of data Circuit Switching has no connection overhead Circuit Swithing is a very eficient mechanism for computer network communications Modern data networks wie circuit switching as its underlying technology Gircuit switching can automatically find a new route to the destination if a circuit fails Which statements about Virtual Local Area Network (VLAN) are true? (Select all that apply) The VLAN identifier is 2 bytes long, thus allowing a maximum of 65,536 VLANs to be defined VUAN allows for the grouping of devices in a logically separated zone on a network VAN rechnology aliows the modification of the destination MAC address The VLAN 10 field is 12 bits long, theoretically allowing up to 4096 VLANs VLAN is identified through an optional 4 byte frame header field in the Ethernet Frame header .
