Question 1

A global site has twelve live copies of a master blueprint. In one regional copy a hero headline was deliberately rewritten and must survive future rollouts, while other inherited components keep receiving blueprint updates. What should the team do on that regional copy?

A. Disable the live relationship for the whole regional site and re-copy the blueprint manually each sprint B. Move the hero component into a separate blueprint that is never rolled out to any live copy C. Cancel inheritance for only the rewritten hero component so later rollouts leave it untouched D. Set a global flag in the Dispatcher so rollouts skip any component whose headline was modified

Question 2

A French site must be created from an English site. Translators edit the French pages independently after the initial copy, and English changes must not roll out automatically. Which Sites capability should be used?

A. Create a live copy with a rollout configuration that triggers on every English modification B. Create a language copy of the English pages with no live relationship C. Publish the English pages to a second Publish service and map its domain to the French locale D. Use a Launch that stages all English changes into the French tree automatically

Question 3

A global retailer shares one set of product pages across markets. Marketing wants shared product tags kept consistent while each market adds its own region labels for filtering. Which content modelling choice best supports this?

A. Create a copy of every product page per market and tag each copy with a different region name B. Store region labels as free-text page properties and skip tagging so authors type what they need C. Store all tags as a single flat list in one DAM folder that every market can edit D. Keep shared tags in the global namespace and add a market namespace

Question 4

A product content fragment must reference a shared legal disclaimer. Legal updates the disclaimer and expects every product that uses it to show the new text without editing each product. Which modelling choice meets this?

A. Copy the disclaimer text into each product fragment and update the copies with a nightly script B. Insert the disclaimer as an Experience Fragment into each product page as static HTML markup C. Store the disclaimer in a root page property that each product fragment reads when it renders D. Use a fragment reference to the shared disclaimer, so one published edit reaches every referencing product on delivery

Question 5

A template designer wants a campaign landing page where the hero section is locked to a fixed layout, while the body below stays free-form for authors. Which editable template approach supports this?

A. Put the hero in the page properties as a text value so authors type the layout they want B. Create two templates, one with the hero and one without, and let authors choose either freely C. Place the hero in the template structure so authors cannot change it, and leave the body as an editable container in initial content D. Hide the hero from authors with an ACL and expect a Dispatcher rule to show it on publish

Question 6

A Sling Model on a page component needs an OSGi service that exists only on Author. The model must still render on Publish without failing. Which approach is safest?

A. Inject the service as required so that a missing service stops the component from rendering early B. Call the service through a static field that is initialised in a static block of the model C. Use optional service injection and a null check in PostConstruct D. Look up the service from the class loader inside every getter call on the model

Question 7

A bundle must support several independent endpoints, each with its own URL and timeout, using one component implementation. Which OSGi pattern supports this?

A. Set the component's configuration policy to require configuration and create one factory configuration per endpoint B. Use one component with several properties named endpoint1, endpoint2, and so on C. Create a separate bundle for each endpoint and deploy each one with its own version D. Read every endpoint from a shared static map that the component fills at activation

Question 8

A servlet must answer GET requests for any node of a card resource type, selected by a specific selector and extension, without claiming unrelated paths. Which registration is most appropriate?

A. Register it with the absolute path of every card node so the servlet is bound to each node B. Bind by the card resource type with GET, a selector, and an extension C. Implement a filter on a wildcard pattern for all requests and forward GET calls manually D. Expose a Sling Model with an exporter and rely on the model to answer GET requests for the component

Question 9

A servlet must return HTTP 404 for unknown resources and let Sling's standard error handling render the configured error page. Which approach should it use?

A. Call sendError with status 404 so Sling applies its error handling B. Write a 200 status with an error property in the JSON body and let clients parse the message C. Throw a RuntimeException so the container returns a generic 500 page for the request D. Redirect every unknown resource to the home page with a 302 response

Question 10

An OSGi service must react when nodes of a custom type are created under a content path, without polling and without blocking authors. Which approach fits?

A. Schedule a Sling Scheduler job every minute that queries the repository for newly created nodes B. Subscribe to every JCR event and filter them inside a synchronous servlet that authors call C. Implement a resource change listener with a path filter for the content path and a type filter for the custom node type D. Register a workflow process step on the content path and make authors wait until it completes

Question 11

A project extends the Core Image component to add a lightbox option, and Core Components will be upgraded independently. Which approach minimises upgrade risk?

A. Copy the full Core Image component into the project and rename its resource type to keep control of the markup B. Create a proxy component with sling:resourceSuperType set to Core Image C. Modify the Core Image HTL file in the core component directory directly so the change applies everywhere D. Add the lightbox script to the Dispatcher so it is injected into every image response

Question 12

A single-page application uses the SPA Editor. Authors save changes, but the preview shows stale model JSON because the model responses are cached at the Dispatcher. Which change fixes the preview without disabling caching for Publish?

A. Disable the SPA Editor and render the React app with server-side Core Component markup B. Increase the Dispatcher TTL so the editor always receives the latest model from the cache C. Exclude author model requests from the Dispatcher cache only D. Remove the model selector from the editable page so the Editor fetches only the default JSON

Question 13

A component renders an author-entered URL in an anchor element. Security review requires that javascript and other dangerous schemes are blocked. Which HTL expression context achieves this?

A. The uri context, which filters dangerous schemes such as javascript from href values B. The unsafe context, which keeps the author value exactly as typed so links work in all schemes C. The text context, which escapes angle brackets but still allows any scheme in attributes D. The html context, which preserves markup and is therefore recommended for href values

Question 14

A shared utilities script must load once per page for every component that needs it, without being copied into each page. Which clientlib approach fits?

A. Put every script into one global clientlib at the site root that loads on every page of the site B. Write script tags directly in each component HTL file so the browser caches each one separately C. Add the utilities inline with style tags in each component so each page carries its own copy D. Give each clientlib a category and pull the shared utilities in through the dependencies property so each loads once

Question 15

A brand wants one editable template to offer different allowed components and style options on two sites, without forking the template. Which configuration achieves this?

A. Create a site-specific design that overrides the template policy per brand B. Create a separate template for each site and copy the initial content into both templates C. Store the allowed component list as a page property on the root page that the HTL reads D. Use the Style System with a CSS class per brand and leave the allowed components unrestricted

Question 16

A rich text component must allow bold and links on one site, but headings and tables on another, with no code changes. Which configuration achieves this?

A. Create a separate rich text component per site with the toolbar buttons hard-coded in its dialog B. Configure rich text features in each site's policy for the component C. Strip all HTML in the HTL template with a regex so every site renders plain text only D. Store the allowed tags as a comma-separated page property that a client-side script reads

Question 17

A Dispatcher serves a parent section listing that stays stale after a new child page is activated. Which Dispatcher setting addresses this?

A. Set statfileslevel so that a change in a child invalidates the cached parent directory B. Set the TTL of the parent directory to zero so every request reaches Publish C. Disable replication for the parent page so the child activation is not sent to Publish D. Add the parent path to the ignoreUrlParams list so its cache key ignores the child

Question 18

A release activated a fix, but the Dispatcher and the CDN both keep old HTML for hours because their lifetimes are long. Which combination minimises staleness while keeping the cache useful?

A. Flush the affected paths on activation and set a moderate CDN lifetime for HTML B. Disable the Dispatcher cache entirely so every request reaches Publish and never serves stale HTML C. Set the lifetime to one year and rely on a weekly manual cache clear by the operations team D. Turn off replication so that Publish always reads the latest content directly from Author

Question 19

Campaign URLs with tracking query parameters create thousands of Dispatcher cache entries and load Publish heavily. Which Dispatcher change reduces this?

A. Add a rewrite rule that appends each tracking parameter to the path so every variant is cached B. Add the tracking parameters to the ignoreUrlParams list C. Disable caching for all paths under the campaign folder so every visitor reaches Publish D. Move the campaign pages to a separate Publish farm that uses a different document root

Question 20

A homepage Sling Model runs an expensive JCR query on every request, and traffic is high while content changes only a few times a day. Which change addresses the root cause and the load?

A. Move the query into browser JavaScript so each visitor runs the query locally B. Increase the Java heap for the Publish JVM and keep the query exactly as it is C. Cache the query result in an OSGi service with time-based expiry, and invalidate it on relevant resource change events D. Add a Dispatcher ignoreUrlParams rule for the query string so every request shares one cache

Question 21

A page shows many large Dynamic Media images, and mobile users download the original uploads. Which approach improves performance without changing author workflow?

A. Serve the original upload to every device and let the browser scale the image with CSS B. Request responsive renditions through the Dynamic Media image service with width parameters so each device receives a suitably sized file C. Store each image as a base64 string in a page property so it loads with the HTML D. Disable image caching in the Dispatcher so every device requests the latest original

Question 22

A content team reports a single-page application login form stores user passwords in a content property for a custom flow. What is the secure replacement?

A. Store the password encrypted with a key kept in the page properties beside the value B. Delegate authentication to AEM's authentication handler or an external IdP C. Hash the password with MD5 in the component before saving it to the page node D. Keep the password in a hidden dialog field so the component can compare it later

Question 23

A form posted from another domain modified author data on the Author instance. The forms use Sling POST. Which control best mitigates this?

A. Disable the Sling POST servlet so forms can only be submitted through the public Publish instance B. Add a random number to every page URL and assume attackers cannot guess the value C. Rely on the browser same-origin policy because the Author instance already uses HTTPS D. Enable the CSRF protection filter and keep the referrer allowlist limited to the Author host

Question 24

A restricted group must not read a sensitive subtree, while its members keep read access to everything else. Which repository configuration achieves this?

A. Remove the group from all ACLs and reinstate read access on each page one by one B. Move the sensitive content under the home folder so the group is excluded by default C. Add a deny entry for the group on the sensitive subtree D. Hide the sensitive subtree in the Sites console by applying a page property

Question 25

Authors sign in through SAML, and group membership is synchronised from the identity provider. A departing contractor must lose AEM access immediately. What is the most reliable control?

A. Disable the account at the identity provider and end active sessions B. Delete the local AEM user profile only, because SAML sign-ins recreate it from a cached copy C. Remove the contractor from the AEM group but leave the account active for audit purposes D. Change the AEM administrator password so the contractor's session token becomes invalid

Question 26

A Cloud Manager pipeline fails a code coverage quality gate on a hotfix branch, and the team needs the fix in production today. What is the appropriate action?

A. Fix the failing tests or coverage gap in the hotfix branch B. Deploy the hotfix manually to production with Package Manager to skip the pipeline gate C. Lower the coverage threshold permanently for the production pipeline D. Disable the security scan step in the pipeline so the build finishes faster

Question 27

Configuration must differ between development and production on Cloud Service, and environment values must stay out of the codebase. Which mechanism meets this?

A. Hard-code the production URL in each bundle and rebuild the project for each environment B. Store the production values as page properties under the conf folder so they load at runtime C. Keep one configuration file on the Author instance and copy it to Publish by hand after each release D. Use run-mode configuration folders deployed per environment, and keep secrets in the Cloud Manager environment variables

Question 28

Editors need to preview unpublished content fragment changes in a headless app before publication. Which pattern supports this without publishing?

A. Publish fragments to a staging Publish instance every hour and point previews at that instance B. Point the preview build at the Author GraphQL endpoint with authenticated access, while production builds keep using the Publish endpoint C. Export the fragments as JSON files and commit them to the front-end repository before each preview D. Enable Dispatcher caching on the Author instance so previews return cached draft content

Question 29

A DAM workflow step must call an external translation service that can take several minutes. Authors must not wait during upload. Which design fits?

A. Call the external service synchronously from a servlet that the author's browser invokes after upload B. Run the translation inside a Dispatcher rewrite rule so it happens on each asset request C. Place the external call in a static initializer of the process step so it runs once at startup D. Run the call as an asynchronous workflow step or Sling job, so the workflow waits for the result instead of blocking the upload request

Question 30

A replication agent's queue backs up because its external endpoint went down. The team must avoid data loss and keep other agents unaffected. Which action is appropriate?

A. Delete the agent's queue and rely on a nightly full content sync to restore the missed changes B. Disable all replication agents until the external endpoint is restored to avoid conflicts C. Set the agent's retry count to unlimited so it retries in parallel with every other agent D. Keep the queue persisted, fix the endpoint, and let it drain in order
