| A. A Time To Live value for the record.
C. A listing of all authoritative DNS servers for the zone.
E. The serial number, which denotes the DNS zone version.
G. A responsible person address in the format person@domain. | |

| Again, i'm with A,C,E. I checked my 216's books and resources and i was able to see that in the SOA TAB, there is a field for the responsible person, but in the format: name.myzone.net. So...i would say "F" and "G" are not valid options.

| Jonoplunk 2003-07-23, 11:02 am |
| I think I'll ammend my answer to be A, C and E, initially I thought it was F too as I remember reading somewhere in the MS book that the Responsible person field was an email address, but looking at the server it is in the format of name.domain.com. | |

OK, we seem to have got there eventually, the answer is ACE
From the Introduction to DNS chapter of the Windows 2000 Resource Kit, an SOA records contains the following information:
The Owner, TTL, Class, and Type fields. The authoritative server field shows the primary DNS server authoritative for the zone. The responsible person field shows the e-mail address of the administrator responsible for the zone. It uses a period (.) instead of an at symbol (@). The serial number field shows how many times the zone has been updated. When a zone's secondary server contacts the master server for that zone to determine whether it needs to initiate a zone transfer, the zone's secondary server compares its own serial number with that of the master. If the serial number of the master is higher, the secondary server initiates a zone transfer. The refresh field shows how often the secondary server for the zone checks to see whether the zone has been changed. The retry field shows how long after sending a zone transfer request the secondary server for the zone waits for a response from the master server before retrying. The expire field shows how long after the previous zone transfer the secondary server for the zone continues to respond to queries for the zone before discarding its own zone as invalid. The minimum TTL field applies to all the resource records in the zone whenever a time to live value is not specified in a resource record. Whenever a resolver queries the server, the server sends back resource records along with the minimum time to live. Negative responses are cached for the minimum TTL of the SOA resource record of the authoritative zone. | |

| Hmmm. The SOA record dictates what the primary authoritative server is. Should you use an ADI zone, you are using a multi-master system, in which case, aren't all considered authoritative?
