A DNS server is experiencing problems resolving hosts. Your troubleshooting efforts identify the
following SOA record as the cause of the problem:
@ soa in host1.abc.com. root.abc.com. (
1002 ; Version number
43200 ; Refresh after 12 hours
3600 ; Retry after 1 hour
604800 ; Expire after 1 week
3600) ; Minimum TTL of 1 hr
What is causing the error?
A.
The soa and in fields are in the wrong order.
B.
The final “)” must be on a line by itself.
C.
A serial number of 1002 is too small.
D.
The soa must be in uppercase.
