FC0-U71 Infrastructure Practice Question
A user connects to a website using its domain name. Which server translates that domain name into an IP address?
⚠ Common exam trap
The trap is confusing DNS with DHCP because both are network services that 'give' something to clients — DNS gives name-to-IP resolution, while DHCP gives IP address configuration; the question specifically asks about translating a domain name.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
DNS server
A DNS (Domain Name System) server translates human-readable domain names like www.example.com into IP addresses that computers use to route traffic. When a user types a domain name, the resolver queries DNS servers to resolve the name to an IP address before the connection can be established.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Proxy server
Why it's wrong here
A proxy server forwards client requests and can cache content, but it does not translate domain names into IP addresses. It is tempting because proxies handle outbound web traffic, yet the resolver that maps a hostname to an IP address is the DNS server.
- ✓
DNS server
Why this is correct
A DNS server resolves human-readable domain names into the numeric IP addresses that clients need to reach the destination host. It satisfies the stem's requirement for name-to-address translation, performing recursive or iterative lookups against the domain hierarchy before returning the resolved record.
- ✗
Web server
Why it's wrong here
A web server hosts and serves the site's content once the client already knows the destination IP address; it does not resolve domain names. It is tempting because the user is visiting a website, but resolution happens before any HTTP request reaches the web server, via DNS.
- ✗
DHCP server
Why it's wrong here
A DHCP server assigns IP addresses, subnet masks and default gateways to clients; it performs no name-to-address lookup. It is tempting because DHCP also hands out DNS server addresses, but the server that actually resolves a domain name into an IP address is the DNS server.
