on a DNS server?
B/D? The record type should be PTR, so D is tempting since it’s correct on that. But the domain should be in-addr.arpa, not .rev. B’s reversed IP looks right except for the typo. So it’s about which error is less bad.
B/D? The record type for reverse DNS is definitely PTR, so B or D seems right. But B has that weird “arpA” typo, which should be “arpa.” D uses “.rev” instead of “.arpa,” which doesn’t look standard either. Since the question might want the closest proper syntax, I’d say B is better despite the typo, because the reversed IP and in-addr.arpa format is the usual way it’s stored. The key is the PTR record and proper reversed IP under in-addr.arpa domain, so B fits best if we overlook the typo.
Yeah, PTR records are the standard for reverse DNS, so gotta go with B.
Maybe B, since PTR records are definitely used for reverse DNS, and the IP reversed in the domain looks right. The capitalization in “arpA” seems like a typo, but the structure fits best here.
B imo, PTR records are definitely the standard for reverse DNS. The reversed IP format is correct even if the exact suffix is a bit off in the option wording.
It’s D because the reverse DNS zone always ends with .in-addr.arpa, not .arpA like in B. The IP is reversed and appended with .in-addr.arpa, so the format in D fits best.
B tbh, PTR records are used for reverse DNS lookups, so option B makes the most sense here.
