Create a host (a) record for computer-12. -explanation: when using the nslookup command to resolve a host name to an ip address, you are performing a forward lookup. to successfully do this, a host (a) record must exist in the zone file for the host name you are trying to resolve. therefore, to resolve the problem, a host (a) record must be created for computer-12. you do not need to create any resource records for computer-01 since you are not specifying this host name in the command. you are simply running the command from computer-01. you do not need to create a pointer (ptr) record. this type of resource record is required to resolve an ip address to a host name. however, in this scenario, you are trying to resolve a host name to an ip address.
