The nic on the server has failed.-when the network interface card (nic) on host fails, it will not be able to ping its loopback address.incorrect answers:a: dns is used to resolve fully qualified domain names (fqdns) to ip addresses.b: dhcp is responsible for automating the assignment of ip configurations to computer systems on a tcp/ip network. if dhcp was down, none of the workstations would be able to access the server but the server would be able to ping its loopback address.c: if the switch was down, we would not be able to access the server but the server would be able to ping its loopback address.references:david groth and toby skandier, network+ study guide (4th edition), sybex, alamedaca, 2005, pp. 117, 136-144, 184.
