Which DNS record type can be updated automatically?

Which DNS record type can be updated automatically?

• A. Static
• B. Dynamic
• C. Both
• D. Neither

Answer: (B)

Dynamic updates are designed to happen without human intervention. A DNS setup that uses dynamic updates allows a client to automatically change its DNS records on the server (for example, A or AAAA records) when its IP address changes, which is common on networks using DHCP. This keeps the domain mapping current without manual edits. Static records, on the other hand, are manually configured and don’t update themselves. So the option that best fits “can be updated automatically” is Dynamic, because it specifically enables automatic changes to DNS records.
