Question 1

Which Drupal core module caches fully rendered pages for anonymous users to reduce server load?

Accepted Answer

Internal Page Cache

Answer

The Internal Page Cache module caches rendered pages for anonymous users, serving subsequent requests directly from cache without bootstrapping Drupal fully.

Question 2

What does Drupal's BigPipe module primarily accomplish?

Accepted Answer

Streams cacheable page parts immediately while lazy-loading uncacheable placeholders

Answer

BigPipe improves perceived performance by streaming the cacheable portions of a page to the browser first, then filling in non-cacheable placeholders asynchronously.

Question 3

What does enabling 'CSS Preprocessing' in Drupal's Performance settings do?

Accepted Answer

Combines multiple CSS files into fewer aggregated files to reduce HTTP requests

Answer

CSS Preprocessing aggregates multiple CSS files into a smaller number of combined files, reducing the number of HTTP requests needed to load a page.

Question 4

What is the purpose of Drupal's cache tags system when integrating with a reverse proxy like Varnish?

Accepted Answer

Tags allow granular cache invalidation so only affected pages are purged when content changes

Answer

Cache tags allow Drupal to tell reverse proxies exactly which cached pages contain a specific piece of content, enabling precise invalidation when that content is updated.

Question 5

What does a cache max-age of 0 signify in Drupal's cacheability metadata?

Accepted Answer

The element is not cacheable and must always be rendered fresh

Answer

A max-age of 0 marks a render element as not cacheable, instructing Drupal's caching system to never store or reuse that element.
