Acquia Certified Drupal Developer — Questions and Answers

Question 1: In Drupal, what is the 'State API' used for versus the 'Configuration API'?

State stores temporary session data; Configuration stores permanent user profiles
State stores per-user preferences; Configuration stores global settings
State stores runtime server-specific values; Configuration stores deployable site settings (Correct answer)
State stores encrypted secrets; Configuration stores public metadata

Correct answer: State stores runtime server-specific values; Configuration stores deployable site settings

The State API stores environment-specific runtime values (like last cron run time) that should NOT be exported; Configuration API stores settings that should travel with the codebase.

Question 2: Which coding standard does the Drupal community officially use for PHP code style compliance?

WordPress PHP Coding Standards
Google PHP Style Guide
PSR-12 exclusively
Drupal Coding Standards (based on PSR-2 with Drupal-specific extensions) (Correct answer)

Correct answer: Drupal Coding Standards (based on PSR-2 with Drupal-specific extensions)

Drupal maintains its own coding standards document that extends common PHP conventions with Drupal-specific rules enforced by PHP_CodeSniffer.

Question 3: What is the value of written documentation in Drupal professional communication?

It is optional
It replaces verbal communication
It is only for formal occasions
It creates permanent records, ensures clarity, and provides legal protection (Correct answer)

Correct answer: It creates permanent records, ensures clarity, and provides legal protection

This is fundamental to Drupal practice. It creates permanent records, ensures clarity, and provides legal protection represents the professional standard for communication in the Drupal certification framework.

Question 4: In Drupal theming, what is the purpose of a 'preprocess function' in a .theme file?

Cache theme suggestion arrays per user role
Override a core module's block output
Compile SCSS to CSS before the theme renders
Add or modify variables available inside a Twig template (Correct answer)

Correct answer: Add or modify variables available inside a Twig template

Preprocess functions (e.g., THEME_preprocess_node()) allow theme PHP code to add, modify, or compute variables that are then passed into corresponding Twig templates.

Question 5: Which Drush command can be used to check whether a Drupal site has any pending database updates that need to be run?

drush updb --check
drush db-pending
drush updatedb-status (Correct answer)
drush status-check

Correct answer: drush updatedb-status

`drush updatedb-status` (alias `updb-status`) lists all pending hook_update_N implementations without actually running them.

Question 6: In Drupal's Twig templating system, how do you safely output a variable to prevent XSS?

<?php print $variable; ?>
{{ variable }} (Correct answer)
{{ variable | raw }}
{% print variable %}

Correct answer: {{ variable }}

The {{ variable }} syntax in Twig automatically escapes output, preventing XSS attacks; use |raw only when the value is already sanitized markup.

Question 7: An agency deploys Drupal configuration between environments using config management. A developer accidentally exports config with a database credential in a YAML file. What is the correct remediation?

Move the credential to settings.php or an environment variable and remove it from git history using git filter-branch or BFG (Correct answer)
Delete the YAML file and force-push to clear git history
Encrypt the YAML file with Drupal's Key module
Rename the YAML file so it is ignored by config-import

Correct answer: Move the credential to settings.php or an environment variable and remove it from git history using git filter-branch or BFG

Credentials must be removed from all git history using a history-rewriting tool and relocated to settings.php or environment variables outside version control.

Question 8: In Drupal, what does enabling Twig debug mode output into the HTML source?

PHP error logs and database query times
Template file paths, theme hook suggestions, and BEGIN/END template comments (Correct answer)
JavaScript console warnings for deprecated API calls
CSS class names and their originating SCSS files

Correct answer: Template file paths, theme hook suggestions, and BEGIN/END template comments

Twig debug mode injects HTML comments showing the exact template file being used, all candidate theme hook suggestions, and begin/end markers for each template.

Question 9: What is the correct format for defining a JavaScript library with a dependency on jQuery in a Drupal libraries.yml file?

import: jquery from core
dependencies: [jquery]
requires: jquery/core
dependencies: - core/jquery (Correct answer)

Correct answer: dependencies: - core/jquery

In Drupal's libraries.yml, dependencies are listed as 'package/library-name' strings under the dependencies key, and Drupal's jQuery is referenced as 'core/jquery'.

Question 10: Which Drupal mechanism reduces the risk of cross-site request forgery (CSRF) attacks on state-changing operations?

Drupal validates the user's IP address on every form submit
Drupal's form API automatically generates and validates unique form tokens (Correct answer)
Drupal's Block system prevents unauthorized form submissions
Drupal forces all POST requests to use HTTPS

Correct answer: Drupal's form API automatically generates and validates unique form tokens

Drupal's Form API includes built-in CSRF tokens (form_token and form_build_id) that are validated on submission, preventing cross-site request forgery.

Question 11: A large Drupal project has stakeholders across legal, marketing, and IT. Who should typically own the content governance policy document?

The Drupal community forums
The lead Drupal developer
The server hosting provider
A designated Content Strategist or Digital Manager who coordinates across all departments (Correct answer)

Correct answer: A designated Content Strategist or Digital Manager who coordinates across all departments

Content governance requires cross-departmental coordination, making a content strategist or digital manager the appropriate policy owner bridging technical and business teams.

Question 12: In Drupal's Twig, what function renders a render array variable into HTML output?

{% print content.field_name %}
{{ render(content.field_name) }}
{{ content.field_name | render }}
{{ content.field_name }} (Correct answer)

Correct answer: {{ content.field_name }}

In Drupal Twig templates, printing a render array variable with {{ variable }} automatically invokes the render pipeline to output its HTML.

Question 13: How do Drupal professionals transfer knowledge from training to practice?

Knowledge transfers automatically
Through supervised practice, mentoring, gradual independence, and ongoing feedback (Correct answer)
By passing the certification exam only

Question 15: What file is required in every Drupal theme to declare its name, regions, and base theme?

theme_name.info.yml (Correct answer)
theme_name.libraries.yml
theme_name.breakpoints.yml
theme_name.theme

Correct answer: theme_name.info.yml

Every Drupal theme must have a .info.yml file declaring its name, type: theme, core_version_requirement, regions, and optional base theme.

Question 16: What is the correct way to define a custom Drupal permission that can be assigned to roles?

Declare it in the module's .permissions.yml file (Correct answer)
Add it to the system.permissions config entity
Add it to the module's .routing.yml under 'requirements'
Register it in hook_install() with permission_save()

Correct answer: Declare it in the module's .permissions.yml file

Custom permissions are declared in a module's .permissions.yml file with a machine name, title, description, and optional restrict access flag.

Question 17: A client insists on using a module with a full security advisory and no available patch. What should a professional Drupal developer do?

Remove the functionality entirely without consulting the client
Refuse all work on the project
Install it anyway since the client accepts the risk verbally
Document the risk formally, obtain written client approval, and implement a compensating control (Correct answer)

Correct answer: Document the risk formally, obtain written client approval, and implement a compensating control

Written acknowledgment plus a compensating control (e.g., WAF rule, access restriction) is the professional approach when a patched alternative doesn't exist yet.

Question 18: Which Drupal community resource serves as the primary hub for reporting security vulnerabilities in contributed modules?

github.com/drupal
drupal.org/security (Correct answer)
drupal.stackexchange.com
groups.drupal.org

The Drupal Security Team publishes all advisories and accepts vulnerability reports at drupal.org/security.

Question 19: In Drupal, what does 'cache tags' invalidation allow?

Tagging content for SEO optimization
Marking cache entries for manual review
Deleting all cache bins at once
Selectively clearing only the cached pages affected by a specific piece of content (Correct answer)

Correct answer: Selectively clearing only the cached pages affected by a specific piece of content

Cache tags let Drupal track which cached responses depend on specific data, so when that data changes only the relevant cached pages are invalidated rather than the entire cache.

Question 20: Which programming language did it have to be written in?

Java
HTML
PHP (Correct answer)
Pascal

Correct answer: PHP

Drupal is primarily written in PHP (Hypertext Preprocessor), a widely used open-source server-side scripting language specifically designed for web development. Its database interactions are typically handled with MySQL or PostgreSQL, making it a powerful and flexible platform for building dynamic websites.

Question 21: What role does active listening play in Drupal practice?

Question 25: A client wants real-time notifications when content is published on their Drupal site. Which module family best addresses this requirement?

Rules + Action modules (Correct answer)
Webform + Notification modules
Search API + Facets modules
Flag + Views modules

Correct answer: Rules + Action modules

The Rules module triggers actions based on events like content publication, making it ideal for real-time notification workflows.

Question 26: What does the principle of 'least privilege' mean when assigning Drupal user roles?

New users should start with no permissions and formally request access upgrades
Anonymous users must always have fewer permissions than authenticated users
Administrators should create separate accounts for privileged versus routine operations
Users should receive only the minimum permissions required to perform their assigned tasks (Correct answer)

Correct answer: Users should receive only the minimum permissions required to perform their assigned tasks

Least privilege means granting each role only the specific permissions needed for its responsibilities, limiting the blast radius if an account is compromised or misused.

Question 27: What risk is introduced when Drupal's update.php is left accessible without authentication after a site update?

The site's cron jobs would run update.php on every cron cycle
Update.php would overwrite custom modules with core defaults
Any visitor could run database updates and potentially corrupt data or escalate privileges (Correct answer)
Search engines would index the update log and expose version information

Correct answer: Any visitor could run database updates and potentially corrupt data or escalate privileges

An unauthenticated update.php allows anyone to trigger database schema changes, risking data corruption, denial of service, or privilege escalation.

Question 28: Which practice best demonstrates a Drupal developer's commitment to backward compatibility when releasing a module update?

Renaming all hooks without an alias
Removing deprecated functions immediately
Incrementing the major version for any API change and following semantic versioning (Correct answer)
Avoiding all API changes indefinitely

Correct answer: Incrementing the major version for any API change and following semantic versioning

Following semantic versioning and incrementing the major version signals breaking changes, allowing site owners to test before upgrading.

Question 29: Which Drupal module allows you to create REST API endpoints without writing custom code?

GraphQL
Services
JSON:API (core) (Correct answer)
RESTful Web Services (core)

Correct answer: JSON:API (core)

The JSON:API module, included in Drupal core since version 8.7, automatically exposes all content entities as REST API endpoints following the JSON:API specification.

Question 31: What Drupal theme setting enables the display of the site logo, site name, and site slogan in the header?

They are configured via the system.site configuration object only
They are controlled by block placement in Block Layout
They are set in Appearance > Settings for the active theme (Correct answer)
They are hardcoded in the page.html.twig template

Correct answer: They are set in Appearance > Settings for the active theme

Site logo, name, and slogan visibility are toggled per-theme in Appearance > Settings, which stores the choices in the theme's configuration.

Question 32: What is the purpose of the 'breakpoints.yml' file in a Drupal theme?

Configure server-side adaptive theme switching per device type
Declare responsive image breakpoints used by core's Responsive Image module (Correct answer)
Set CSS media query values for the theme's grid system
Define JavaScript event listeners for window resize events

Correct answer: Declare responsive image breakpoints used by core's Responsive Image module

A theme's breakpoints.yml file registers named breakpoints (e.g., mobile, tablet, desktop) that the core Responsive Image module uses to serve appropriately sized images.

Question 33: Which Drush command regenerates CSS/JS aggregate files and clears the Drupal theme registry?

drush asset:rebuild
drush cr (cache:rebuild) (Correct answer)
drush theme:rebuild
drush php:eval drupal_flush_all_caches()

Correct answer: drush cr (cache:rebuild)

drush cr (cache:rebuild) clears all Drupal caches including the theme registry, asset aggregates, Twig compiled templates, and the service container.

Question 34: A junior developer on your team hardcodes a user role check using a role ID integer instead of the role machine name. Why is this a professional concern?

Role IDs can differ between environments, making the code environment-dependent and fragile (Correct answer)
Hardcoding role IDs improves performance
Role IDs are always the same across environments, so there is no real issue
Drupal automatically translates role IDs to machine names

Correct answer: Role IDs can differ between environments, making the code environment-dependent and fragile

Role IDs are auto-incremented and may differ between development, staging, and production databases, making machine names the only reliable identifier.

Question 35: Which tool do Drupal developers use to enforce coding standards automatically during development?

Xdebug
PHP_CodeSniffer with the Drupal ruleset (Correct answer)
Composer
Drush

Correct answer: PHP_CodeSniffer with the Drupal ruleset

PHP_CodeSniffer with the Drupal and DrupalPractice sniff sets automatically detects coding standard violations in Drupal projects.

Question 36: A university's Drupal site was hacked and backdoor PHP files were found in the public files directory. What hardening measure directly prevents this attack vector?

Restrict PHP execution in the public files directory via server configuration (e.g., deny .php in Nginx) (Correct answer)
Move the files directory inside the Drupal docroot
Enable Drupal's File Security module to scan uploads
Set the files directory to read-only using file system permissions

Correct answer: Restrict PHP execution in the public files directory via server configuration (e.g., deny .php in Nginx)

Configuring the web server to deny execution of PHP (and other scripts) inside the public files directory prevents uploaded malicious files from being executed.

Question 37: What is the significance of a code of conduct for Drupal professionals?

It establishes expected behaviors and ethical standards that protect the public and profession (Correct answer)
It limits professional freedom
It is merely symbolic
It applies only to new practitioners

Correct answer: It establishes expected behaviors and ethical standards that protect the public and profession

Generate sitemaps automatically
Block bots from crawling admin pages
Redirect broken URLs to valid paths
Create URL aliases based on configurable patterns (Correct answer)

Correct answer: Create URL aliases based on configurable patterns

Pathauto automatically generates clean URL aliases for nodes, taxonomy terms, and users using token-based patterns.

Question 39: Which Drupal theming approach allows you to override a contrib module's template from your custom theme?

Declare an override in the theme's .breakpoints.yml
Copy the template to themes/custom/mytheme/templates/ with the same filename (Correct answer)
Add the module template directory to the theme's info.yml
Create a hook_theme_registry_alter() to redirect the path

Correct answer: Copy the template to themes/custom/mytheme/templates/ with the same filename

Placing a template file with the same name inside your theme's templates directory causes Drupal to use your copy instead of the module's original template.

Question 40: Which Drupal core module allows administrators to communicate site maintenance windows to logged-in users?

Block module with role visibility
Custom Menu module
Site Maintenance mode with a custom message (Correct answer)
Announcements Feed module

A CSS class automatically applied to body tags based on content type
A Twig macro that suggests reusable partial templates
A configuration flag that enables dark-mode theming
A prioritized list of template filenames Drupal tries before falling back to defaults (Correct answer)

Correct answer: A prioritized list of template filenames Drupal tries before falling back to defaults

Theme suggestions give Drupal an ordered list of template filenames to try (e.g., node--article.html.twig before node.html.twig), enabling granular per-bundle overrides.

Question 42: Which strategy should a QA team adopt to validate that a Drupal site's Views-generated pages remain correct after a database schema change?

Exporting the view configuration to YAML and diffing it against a baseline
Automated functional tests that assert specific field values appear in the rendered view output (Correct answer)
Running `drush cr` and checking the Drupal status report
Manually browsing each view page after the schema change

Correct answer: Automated functional tests that assert specific field values appear in the rendered view output

Functional tests that render views and assert expected field values in the HTML output will immediately fail if a schema change causes a view query to break or return unexpected data.

Question 43: An organization accepts the risk of running an end-of-life Drupal version on an isolated internal tool. Which risk management strategy does this represent?

Risk acceptance with documented justification (Correct answer)
Risk avoidance by decommissioning the tool
Risk transference by purchasing cyber insurance

A Drupal module for managing assets
The PHP templating engine used to render HTML output (Correct answer)
A front-end build tool
A CSS framework bundled with Drupal

Correct answer: The PHP templating engine used to render HTML output

Drupal 8+ uses the Twig templating engine, which separates business logic from presentation and auto-escapes output for security.

Question 47: A stakeholder claims a published article is missing from the site search. After checking content is published, what should be investigated next?

Whether the Search index has been rebuilt and includes the content type (Correct answer)
Whether the node's URL alias is too long
Whether the theme's page template is correct
Whether CKEditor is enabled on the body field

Correct answer: Whether the Search index has been rebuilt and includes the content type

Search results depend on an up-to-date index; if the content type is excluded or the index hasn't rebuilt, content won't appear in search.

Question 48: Which coding standard tool is most commonly used for Drupal PHP code quality checks in CI pipelines?

PHPStan alone
SonarQube PHP plugin
PHP_CodeSniffer with Drupal standards (Correct answer)
Psalm

Correct answer: PHP_CodeSniffer with Drupal standards

Correct answer: NIST SP 800-53 controls at the appropriate impact level

FedRAMP requires cloud systems hosting federal data to implement NIST SP 800-53 security controls at Low, Moderate, or High impact level.

Question 50: In Drupal theming, what is the difference between a 'template_preprocess' hook and a theme-specific 'THEME_preprocess' hook?

template_preprocess runs after rendering; THEME_preprocess runs before asset attachment
template_preprocess is deprecated; THEME_preprocess is the only supported pattern
template_preprocess only works for node templates; THEME_preprocess works for all entity types
template_preprocess runs in modules; THEME_preprocess runs last and can override module variables (Correct answer)

Correct answer: template_preprocess runs in modules; THEME_preprocess runs last and can override module variables

template_preprocess hooks in modules run first to set default variables; THEME_preprocess hooks in the active theme run last, giving themes final control to override or extend variables.

Question 51: What Drupal behavior pattern is used to safely attach JavaScript functionality to dynamically loaded AJAX content?

Drupal.behaviors with attach() and detach() methods (Correct answer)
window.onload event listeners
jQuery .ready() document handlers
DOMContentLoaded event listeners

Correct answer: Drupal.behaviors with attach() and detach() methods

Drupal.behaviors objects with attach() methods are called both on full page load and after every AJAX response, ensuring JS initializes correctly on dynamic content.

Question 52: A stakeholder requests that certain editorial comments on content be visible only to editors, not to the public. Which Drupal feature supports this?

Custom block visibility
Path aliases
Taxonomy terms
Revision log messages (Correct answer)

Correct answer: Revision log messages

Revision log messages are stored per revision and are only accessible to users with permission to view revision history, keeping editorial notes internal.

Question 53: In a Drupal theme's libraries.yml, what does the 'minified: true' flag tell Drupal?

Drupal should automatically minify the file during caching
The file is already minified and Drupal should not attempt to aggregate it further (Correct answer)
Only serve this file when CSS aggregation is enabled
Skip this file during automated front-end testing

Correct answer: The file is already minified and Drupal should not attempt to aggregate it further

The 'minified: true' flag tells Drupal's asset aggregation system that the file is already minified so it can skip redundant re-minification during aggregation.

Question 54: How do you attach a CSS or JS library to a specific Twig template in Drupal?

Call drupal_add_css() in the theme's .theme file
Use @import in CSS files
Add {{ attach_library('mytheme/library-name') }} in the Twig file (Correct answer)
List the file in the .info.yml css section

Correct answer: Add {{ attach_library('mytheme/library-name') }} in the Twig file

The attach_library() Twig function loads a named library (defined in libraries.yml) only on pages where that template renders, avoiding global CSS/JS bloat.

Question 55: A Drupal site must display a GDPR-compliant cookie notice that does not use 'pre-ticked' consent boxes. What does this mean technically?

Non-essential cookies must be disabled by default until the user actively gives consent (Correct answer)
Analytics cookies require a separate consent form
Cookies must be opt-out, not opt-in
Cookie notices must appear only on the homepage

Correct answer: Non-essential cookies must be disabled by default until the user actively gives consent

GDPR requires freely given, specific, informed, and unambiguous consent — non-essential cookies must be off by default, with consent obtained before they fire.
