This LPIC-2 practice question tests your understanding of dns, web and mail services. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A company wants to host multiple websites on a single Apache server with different domain names. Which approach is most appropriate?
Name-based virtual hosting
Allows multiple domain names on a single IP/port using the Host header.
IP-based virtual hosting
Why wrong: Requires multiple IP addresses, which may not be available.
Port-based virtual hosting
Why wrong: Requires different ports, which is not standard for web browsing.
Using mod_rewrite for each domain
Why wrong: mod_rewrite is for URL manipulation, not for virtual hosting.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Name-based virtual hosting
Name-based virtual hosting allows a single Apache server to serve multiple websites using the same IP address and port by relying on the HTTP Host header sent by the client. This is the most efficient and commonly used method for hosting multiple domains on one server, as it conserves IP addresses and requires minimal configuration via the `<VirtualHost *:80>` directive.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Name-based virtual hosting
Why this is correct
Allows multiple domain names on a single IP/port using the Host header.
Related concept

IP-based virtual hosting
Why it's wrong here
Requires multiple IP addresses, which may not be available.
Port-based virtual hosting
Why it's wrong here
Requires different ports, which is not standard for web browsing.
Using mod_rewrite for each domain
Why it's wrong here
mod_rewrite is for URL manipulation, not for virtual hosting.
Common exam traps
The trap here is that candidates often confuse name-based virtual hosting with IP-based hosting, assuming each domain needs its own IP address, or mistakenly think mod_rewrite can handle domain routing without virtual host containers.
Detailed technical explanation
Name-based virtual hosting works by Apache examining the `Host` header in the HTTP/1.1 request (RFC 7230) to determine which virtual host configuration to apply. A subtle behavior is that SSL/TLS (HTTPS) complicates this because the Host header is encrypted until the TLS handshake completes; this is why SNI (Server Name Indication) was introduced, allowing the client to indicate the domain name during the TLS handshake so Apache can select the correct certificate and virtual host.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A practitioner preparing for the LPIC-2 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
