Website was very helpful. Thaks for posting. The answer is definitely B.
I was under the impression that it was A until I read the article posted. Thanks for helping.
Yea I would think the answer would be B. as well.
The Answer is B (DNSSEC). To facilitate signature validation, DNSSEC adds a few new DNS record types:
RRSIG – Contains a cryptographic signature
DNSKEY – Contains a public signing key
DS – Contains the hash of a DNSKEY record
NSEC and NSEC3 – For explicit denial-of-existence of a DNS record
CDNSKEY and CDS – For a child zone requesting updates to DS record(s) in the parent zone.
