Map the Sling request pipeline from URL to rendered output by tracing a resource path through the resource resolver, servlet/servlet-resolution rules, and the selected rendering script

Configure three OSGi components using Declarative Services annotations (@Component, @Activate, @Reference) and change one configuration value at runtime through the Web Console

Define a custom JCR node type with at least four properties and one mandatory property, register it in a CND file, and create a node of that type in CRXDE

Explain and demonstrate the difference between a hard reference and a weak reference when deleting an OSGi service consumer

Build two Sling Models: one adapted from Resource and one adapted from SlingHttpServletRequest, and inject values with @ValueMapValue, @ChildResource, and @OSGiService

Write a servlet registered by resource type and verify its output with a curl request in the browser against a local instance

Author a proxy component over a core component and override one HTL block without copying the whole script

Document the JCR namespaces, mixin types, and index rules needed for a custom query you write with the QueryBuilder API

Create an editable template with at least three policy-driven component restrictions and two responsive layout configurations

Implement an HTL component using data-sly-use, data-sly-list, data-sly-resource, and the contextual resource parameter, with no scriptlets or JSP

Build a dialog with a multifield, a nested composite field, and a validation rule, then verify the persisted JSON in the JCR

Register a client library with categories, dependencies, and embed rules, and confirm the generated CSS/JS bundle through the HTML clientlib include

Configure MSM on a blueprint-to-live-copy relationship, roll out one page edit, and break the inheritance on a single component to observe the detached state

Create a language copy and link it to a translation project to show the copy structure

Add two custom workflow steps or launchers that trigger on page activation and log the payload

Map how template policies, content policies, and the design configuration differ between static and editable templates

Configure replication agents for author and publish, including one custom agent transport handler, and verify with a test connection

Build a user group structure with three groups, assign ACLs at /content and /apps at differing privilege levels, and prove the effect with a test user

Set up two distinct maintenance tasks such as workflow purge and version purge and record their default configuration

Explain the difference between an author-only and publish-only service and list the bundles you would verify after a package install

Implement a client-side component that lazy-loads its JavaScript from a categorized clientlib and measures render impact in the browser performance panel

Serve three image renditions through the image component with a defined smart-crop configuration and compare delivered asset dimensions

Configure a dynamic media or asset metadata schema with custom fields, then upload an asset and verify the extracted metadata

Write a component that consumes the model JSON endpoint (model.json) and renders a list client-side

Write a Dispatcher farm file including a cache rule set, a filter allowlist, statfileslevel, and an invalidate section

Simulate author activation triggering a POST to /dispatcher/invalidate.cache and confirm the correct paths are flushed

Set cache headers and TTL behavior for HTML versus clientlibs and document which one you would not raise and why

Stand up a local Dispatcher with Docker in front of a local publish instance and verify a cached versus uncached response via response headers

Retake a timed 60-question practice set across all five domains and log the reasoning for every missed item

Re-derive from memory the Sling resolution order, editable template to policy relationship, and Dispatcher invalidation flow

Review every flagged weak area from weeks 1 through 7 and rewrite the corresponding cheat sheet section

Practice explaining three architecture trade-offs out loud in under two minutes each
