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.
Which Apache module is used to rewrite URLs based on rules?
mod_rewrite
mod_rewrite is the module that provides a rule-based rewriting engine.
mod_proxy
Why wrong: mod_proxy is used to proxy requests to another server, not for URL rewriting.
mod_alias
Why wrong: mod_alias provides simple URL mapping but not rule-based rewriting.
mod_redirect
Why wrong: mod_redirect is not a standard Apache module; redirects are implemented by mod_alias or mod_rewrite.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
mod_rewrite
mod_rewrite is the correct Apache module for rewriting URLs based on rules. It uses a regular expression engine to match incoming request URIs against patterns defined in .htaccess or server configuration files, then transforms them according to specified substitution rules. This module is essential for creating clean URLs, redirecting traffic, and implementing URL-based access control.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis

mod_proxy
Why it's wrong here
mod_proxy is used to proxy requests to another server, not for URL rewriting.
mod_alias
Why it's wrong here
mod_alias provides simple URL mapping but not rule-based rewriting.
mod_redirect
Why it's wrong here
mod_redirect is not a standard Apache module; redirects are implemented by mod_alias or mod_rewrite.
Common exam traps
The trap here is that candidates may confuse mod_alias's Redirect directive (which performs simple, static redirects) with the dynamic, rule-based rewriting capability of mod_rewrite, or incorrectly assume a module named 'mod_redirect' exists.
Detailed technical explanation
mod_rewrite operates by processing a set of RewriteRule directives, each consisting of a pattern (Perl-compatible regular expression), a substitution string, and optional flags (e.g., [L] for last rule, [R] for external redirect). It can also use RewriteCond directives to apply conditions based on server variables like HTTP_HOST or QUERY_STRING. A real-world scenario is implementing a canonical URL redirect (e.g., forcing www.example.com to example.com) where mod_rewrite checks the hostname and issues a 301 redirect only when needed, preserving SEO rankings.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A small business has 20 workstations on the 192.168.1.0/24 network and one public IP from its ISP. The router uses PAT (NAT overload) so all 20 devices share one public address using different source ports. NAT questions test whether you understand the four address terms and which direction each translation applies.
