The SOA (Start of Authority) record is a DNS record that defines the authoritative information about a domain. Its format includes the following fields:
(domain) IN SOA (Primary Name Server) (Responsible Email)
(Serial) (Refresh) (Retry) (Expire) (Minimum TTL)
Given:
Rutgers.edu. SOA NS1.Rutgers.edu ipad.college.edu (200302028 3600 3600 604800 2400.)
Field values:
Serial: 200302028 (→ This is the version number of the zone file.)
Refresh: 3600 seconds
Retry: 3600 seconds
Expire: 604800 seconds
Minimum TTL: 2400 seconds
These values represent key configurations and are all part of the SOA record's operational data.
A: 200302028 = Serial/version (correct)
B: 3600 = Refresh (correct)
C: 604800 = Expire (correct)
D: 2400 = Minimum TTL (correct)
Incorrect Options:
E and F (60, 4800): Not part of the SOA record shown.
