Drupal Case Studies & Practical Application 4

Question 1

A Drupal 10 site must expose content to a React frontend via JSON:API. An endpoint returns 403 for authenticated users on a specific content type. What should you check first?

Accepted Answer

The content type's 'View published content' permission for the user's role

Answer

JSON:API respects Drupal's node access system; if authenticated users get 403, the role is missing the 'View published content' permission for that content type.

Question 2

A client running Drupal 9 must urgently apply a security advisory. The fix is available only in Drupal 10. What is the correct order of operations?

Accepted Answer

Apply any available Drupal 9 patch first, then plan the Drupal 10 upgrade

Answer

Check for any available Drupal 9-compatible patch or release first; if none exists, applying a manual backport and then scheduling the major version upgrade is the responsible path.

Question 3

An agency builds a Drupal distribution (install profile) for clients. Clients report that running `drush config-import` overwrites customizations they made post-install. What is the root cause?

Accepted Answer

Clients must use config_split to manage environment-specific overrides

Answer

Config Split allows separating environment-specific or client-specific configuration from the shared base configuration, preventing client customizations from being overwritten during imports.

Question 4

A multilingual Drupal site serves English and Spanish. The SEO team finds Spanish pages are not indexed because hreflang tags are missing. What module generates hreflang tags in Drupal core?

Accepted Answer

Content Translation module adds hreflang automatically when translations exist

Answer

Drupal core's Content Translation module automatically outputs hreflang link elements in the HTML head for each available translation of a node.

Question 5

A media agency needs video files transcoded to multiple formats after upload in Drupal. Which approach best fits this requirement?

Accepted Answer

Integrate a cloud transcoding service via a queue worker triggered on media entity save

Answer

Triggering a queue worker that calls a cloud transcoding API (e.g., Mux, Transloadit) on media entity save offloads CPU-intensive work and scales reliably.
