FC0-U71 Practice Question: Based on the exhibit, which of the following is…
Exhibit
Refer to the exhibit. ipconfig /all output: IPv4 Address: 192.168.1.100 Subnet Mask: 255.255.255.0 Default Gateway: 192.168.1.1 DHCP Server: 192.168.1.1 DNS Server: 8.8.8.8
Based on the exhibit, which of the following is the purpose of the DNS server address?
⚠ Common exam trap
Candidates often confuse the DNS server's role with that of a DHCP server or a router, especially when the exhibit shows network configuration fields where both DNS and gateway addresses are listed.
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
✓
To convert domain names to IP addresses
The DNS server address is used to resolve human-readable domain names (like www.example.com) into machine-readable IP addresses. This is the fundamental purpose of the Domain Name System, which translates names to IPs so that network devices can locate and communicate with each other.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
To convert domain names to IP addresses
Why this is correct
DNS resolves human-readable domain names into routable IP addresses, letting clients locate servers without hard-coded numeric endpoints. This satisfies the exhibit's requirement that name queries reach the correct host, since DNS is the service responsible for forward lookups within the network's name resolution chain.
- ✗
To encrypt network traffic
Why it's wrong here
Encrypting network traffic is handled by protocols such as TLS or IPsec, not by the DNS server address, which merely identifies the resolver clients query. It is tempting because DNS traffic itself can be encrypted via DoH or DoT, and such a mechanism would be correct where resolver privacy is the stated requirement.
- ✗
To route packets to the internet
Why it's wrong here
Routing packets to the internet is the default gateway's role; the DNS server address only resolves hostnames into IP addresses before routing occurs. It is tempting because both appear in the same IP configuration dialog, and the gateway address would be correct where forwarding traffic beyond the local subnet is required.
- ✗
To assign IP addresses to clients
Why it's wrong here
Assigning IP addresses to clients is DHCP's function, not DNS's; the DNS server address only tells clients which resolver to query for name resolution. It is tempting because both are network configuration values delivered to clients, and DHCP would be the correct answer where automatic address allocation is required.
