A user wants to access a website but types the wrong URL. Which technology resolves domain names to IP addresses?
⚠ Common exam trap
Many exam-takers confuse DNS with DHCP because both involve network configuration, but DHCP assigns IP addresses dynamically while DNS resolves names to IPs; Cisco tests this distinction by pairing them as distractors.

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
DNS (Domain Name System) is the technology that translates human-readable domain names (like www.example.com) into machine-readable IP addresses (like 192.0.2.1). When a user types a wrong URL, the browser still sends a DNS query to resolve the domain portion of the URL; if the domain is valid but the path is wrong, DNS resolves correctly, but if the domain itself is mistyped, DNS may fail or redirect to a different IP. This resolution is essential for locating the web server on the internet.

Same concept, more angles
4 more ways this is tested on FC0-U71
These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. A user connects to a website using its domain name. Which server translates that domain name into an IP address?
hard- A.Proxy server
- ✓ B.DNS server
- C.Web server
- D.DHCP server
Why B: DNS (Domain Name System) servers resolve domain names to IP addresses, enabling browsers to locate web servers.
Variation 2. Which of the following is used to translate human-readable domain names (like www.example.com) into IP addresses that computers use to identify each other on the network?
easy- A.NAT
- B.HTTP
- C.DHCP
- ✓ D.DNS
Why D: DNS (Domain Name System) resolves domain names to IP addresses, allowing users to access websites using easy-to-remember names instead of numeric IP addresses.
Variation 3. A technician is troubleshooting a network connectivity issue. The user can access local network resources but cannot browse the internet. The technician suspects a DNS problem. Which of the following is the primary function of DNS?
hard- A.Filter unwanted network traffic
- ✓ B.Translate domain names to IP addresses
- C.Provide wireless network access
- D.Assign IP addresses to devices on the network
Why B: DNS translates human-readable domain names (e.g., www.example.com) into IP addresses that computers use to communicate.
Variation 4. A user reports that they can access websites by IP address but not by domain name. Based on the exhibit, which of the following is the MOST likely cause?
medium- A.Duplicate IP address on the network
- B.Incorrect default gateway
- C.Incorrect subnet mask
- ✓ D.Incorrect or unreachable DNS server
Why D: The user can access websites by IP address but not by domain name, which indicates that IP routing and connectivity are functioning correctly. The failure to resolve domain names points directly to a DNS issue, such as an incorrect or unreachable DNS server. DNS translates human-readable domain names into IP addresses; without a working DNS server, name resolution fails while direct IP access remains unaffected.
