_http._tcp.test.com. IN SRV 0 0 80 server1.wh.test.com.
_http._tcp.test.com. IN SRV 10 0 80 server2.wh.test.com.
A. Server2 will be the preferred server because it has a priority value of 10.
B. Server1 will be the preferred server because it is listed first.
C. Server1 will be the preferred server because it has a priority value of 0.

Mmmm...ok, let me think. If i recall well, the meaning of the SRV record is:
SRV 0 0 80 (Server 1)
SRV 10 0 80 (Server 2)
For Server 1
1st number (0 in this case): priority
2nd number (0 in this case): weight
3rd number (80 in this case): port Number
For Server 2
1st number (10 in this case): priority
2nd number (0 in this case): weight
3rd number (80 in this case): port Number
Priority: lower values have higher priority. If two records have the same priority, then the "weight" is used, and the record with heavy weight wins.
So, my answer is letter "C"...

| The answer is C. Priority takes precedence. | |

And the answer is of course C. Server1 will be the preferred server because it has a priority value of 0.
Well done everyone
From the Introduction to DNS chapter of the Windows 2000 Resource Kit, the format of an SRV record is as follows:
_Service._Proto.Name TTL Class SRV Priority Weight Port Target
The Priority field specifies the priority of the host. Clients attempt to contact the host with the lowest priority. |
