You are one of the network administrators for your company. The network hosts several computers running Microsoft Windows Server 2003. Client computers are running Microsoft Windows XP Professional. One of the servers is configured as a Domain Name System (DNS) server. This server maintains the primary forward zone and reverse lookup zone for the company domain. You attempt to use the Nslookup command from your administrative workstation, Computer-01. You are unable to resolve the host name of Computer-12 to an IP address using the command. You can successfully use the command to resolve the host names of other computers on the network to IP addresses. You need to be able to resolve the host name of Computer-12 to an IP address. What should you do?
A. Create a host (A) record for Computer-01. B. Create a pointer (PTR) record for Computer-12. C. Create a pointer (PTR) record for Computer-01. D. Create a host (A) record for Computer-12.
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.
