The Forward lookup zone resolves the __________.

The Forward lookup zone resolves the __________.

• A. IP address to host name
• B. Domain to IP
• C. Mail exchange
• D. Host name to IP address

Answer: (D)

Forward lookup zones are used to translate a host name into an IP address. When you query a hostname like server.example.com, the DNS server looks for an A record (for IPv4) or an AAAA record (for IPv6) in the forward lookup zone and returns the corresponding numeric IP. This allows applications to be reached by human-friendly names while the network routes traffic using IP addresses. The opposite function is done by the reverse lookup zone, which maps IP addresses back to host names using PTR records. Other options refer to different DNS records (like MX for mail) and aren’t how forward lookups resolve names to addresses. Hence, the correct description is host name to IP address.
