Please review this question.
The answer I believe should be:
✔ Correct choice:
Responds to a request for IP address to domain name resolution to the DNS server.
Why the other options are incorrect
- “Serves requests over destination port 53.”
? This describes a technical detail of DNS transport (DNS typically uses port 53), not the lookup operation itself.
- “DNS server pings the destination to verify that it is available.”
❌ DNS does not ping hosts or check availability.
- “DNS server forwards the client to an alternate IP address when the primary IP is down.”
❌ This describes load balancing or failover behavior, not the fundamental DNS lookup process.
