AWS Certified Advanced Networking – Specialty (ANS-C00) — Question 272

Which is not a valid Route 53 record?

Answer options

• A. SPF
• B. NAPTR
• C. AAAA
• D. BFD

Correct answer: D

Explanation

Amazon Route 53 supports a wide variety of DNS record types, including SPF, NAPTR, and AAAA records. BFD, which stands for Bidirectional Forwarding Detection, is a network routing detection protocol rather than a valid DNS resource record type. Therefore, BFD is the only option listed that cannot be configured in Route 53.
