Implementing and Operating Cisco Enterprise Network Core Technologies (ENCOR) — Question 627

Which DNS record type is required to allow APs to discover a WLC by using DNS on IPv4?

Answer options

• A. NS
• B. A
• C. SOA
• D. MX

Correct answer: B

Explanation

The correct answer is B, as an A record maps a domain name to an IPv4 address, which is essential for APs to locate the WLC. The other options do not serve this purpose: NS records define the name servers for a domain, SOA records provide administrative information about the domain, and MX records are used for email routing.
