|  And today's poser is ....
Q22. To aid with troubleshooting, you need to provide the ability for some of the other administrators in your company to perform reverse lookups on several of your servers. They need to be able to enter the IP address of the server and receive the host name of the machine in return. However, some of these machines have been configured to dynamically update their records with the DNS server and therefore you will have to enter these records manually. What type of records must you create to support reverse lookup queries?
A. Reverse Lookup (RL)
B. Name Server (NS)
C. Pointer (PTR)
D. Service (SRV)
E. Host (A)
F. Reverse Query (RQ)
Good Luck .... see you tomorrow for the answer!! | |

Correct Answer: C
The following resource records are commonly used in Windows 2000:
A (Host Address) - Used to hold a specific host's IP address.
CNAME (Canonical Name or Alias) - Used to make an alias name for a host.
MX (Mail Exchanger) - Provides message routing to a mail server, plus backup server(s) in case the target server isn't active.
NS (Name Server) - Provides a list of authoritative servers for a domain or indicates authoritative DNS servers for any delegated sub-domains.
PTR (Pointer) - Used for reverse lookup—resolving an IP address into a domain name using the IN-ADDR.ARPA domain.
SOA (Start of Authority) - Used to determine the DNS server that's the primary server for a DNS zone and to store other zone property information.
SRV (Service Locator) - Provides the ability to find the server providing a specific service. Active Directory uses SRV records to locate domain controllers, global catalog servers, and Lightweight Directory Access Protocol (LDAP) servers. |
