dashboard. The content displayed in this dashboard differs strictly depending on whether the current user is
an anonymous visitor, a standard authenticated user, or an administrator. Which cache configuration MUST be
added to the render array so the page is cached correctly without accidentally serving administrator-only
content to anonymous users?
Choose one answer.

A '#cache' => ['contexts' => ['user']]

B '#cache' => ['contexts' => ['user.roles']]

C '#cache' => ['tags' => ['user_roles']]

D '#cache' => ['max-age' => 0]


4. (Cache Tags - List Invalidation) Scenario: You built a custom block rendering a grid of the 5 most recently
updated 'News' nodes. Which cache configuration must you add to the render array so the block's cache

Choose one answer.

6. (Events vs Hooks - Modifying HTTP Headers) Scenario: The security team requires that a custom HTTP
header (X-Acme-Security-Policy: strict) be attached to the HTTP Response of every single page request served
by Drupal. What is the correct modern mechanism to alter the HTTP response and append this header before it
is dispatched to the browser?
Choose one answer.

A Implement hook_page_attachments_alter() in the .module file.

B Create an Event Subscriber that listens to the KernelEvents::RESPONSE event.

C Implement hook_exit() to modify the PHP header() function directly.

D Add the header definition to the module's my_module.info.yml file.
