Drupal Interview Questions

Q   |   QA

- 3MB of disk space

- If you install many contributed modules and contributed themes, the actual disk space for your installation could easily be 40 MB or more (exclusive of database content, media, backups and other files).

Web Server
Drupal has been deployed successfully on both Apache and IIS.
Drupal is being developed to be web server independent, but we have limited or no reports of successful use on web servers not listed here.

Database server
Recommended: MySQL 4.1 or MySQL 5.0
PostgreSQL 7.4 or higher

Websites built using just Drupal core (i.e. with no additional, contributed modules) are compatible with, and fully functional, in all modern browsers that support CSS and JavaScript. However, browsers have varying levels of compliance with Internet standards such as CSS 2, so there may be minor variations in appearance.
Here is an incomplete list of browsers that are known to work well with Drupal core and support all of its features:

  • Internet Explorer 6.x and later
  • Firefox 2.x and later
  • Opera 7 and later
  • Safari 1.x and later
  • Camino 1.x and later
  • Google Chrome

It’s worth mentioning here that IE6 has an problem with loading more than 30 stylesheets, and it’s fairly easy to run into this problem once you start adding contrib modules.

PHP
Recommended: PHP 5.2.x
Required: PHP version 4.3.5 or higher (Contributed modules may not support this version of PHP)

PDO is an acronym for PHP Data Objects. PDO is a lean, consistent way to access databases. This means developers can write portable code much easier. PDO is not an abstraction layer like PearDB. PDO is a more like a data access layer which uses a unified API (Application Programming Interface).

The standard Drupal installation contains a sample .htaccess file which supports clean URLs. It is easy to miss copying this file, because of the leading “dot”. So before trying to enable Clean URLs, make sure this file exists in your Drupal installation.

Drupal 6.x

In Drupal 6, the installer tests for compatibility with Clean URLs as a part of the installation process.

Drupal 5.x

Goto the administer >> site configuration >> clean urls section of the administrative interface.
Clean urls can be enabled by following the above two options in respective versions of drupal website.

1. Block — Controls the boxes that are displayed around the main content.
2. Filter — Handles the filtering of content in preparation for display.
3. Node — Allows content to be submitted to the site and displayed on pages.
4. System — Handles general site configuration for administrators.
5. User — Manages the user registration and login system.
