Updating the cache in AEM is critical to ensure that users receive the most current content without unnecessary delays. Two common methods used to update the cache include:
A: Content Updates - Content updates can trigger an invalidation or flush of the cache. When content is published or updated on the AEM author instance and replicated to the publish instance, the dispatcher cache can be set to automatically invalidate the affected pages. This ensures that the next request to these pages serves the latest content.
D: Auto-invalidation on the Dispatcher - The dispatcher can be configured to automatically invalidate cached content under certain conditions, such as when a TTL (Time To Live) expires or when specific actions occur, such as a page activation ordeactivation. This is often preferred to manual cache clearing as it can be more efficient and targeted to the specific content that has changed.
Options B and C are incorrect because restarting the AEM Author or Publish instances does not directly relate to cache update methods. These actions are more associated with system maintenance or updates and would not be standard practice for updating cached content.

In Maven, themaven-clean-pluginis used to clean the project by removing files generated at build-time in the targetdirectory. Before a new build, cleaning the project is a common practice to ensure that no stale artifacts affect the new build. The plugin's goalcleanis bound to the clean phase of the build lifecycle and can be executed with the commandmvn clean.
Option A,mvn-clean-plugin, is incorrectly named; the correct name ismaven-clean-plugin.
Option B,maven-scr-plugin, is related to Service Component Runtime and not to cleaning build artifacts.

Global project properties in a Maven project are typically defined in the<properties>section of the parent pom.xmlfile. This allows these properties to be shared across all modules of the project, ensuring consistency and easy maintenance of project-wide settings such as versions of dependencies, plugin configurations, and other properties that are common across multiple modules of the project.

AEM service pack release notes typically include information that helps users understand the changes that the service pack will bring to their AEM instance. These release notes commonly include:
A: Deprecated features - This section informs users about the features that are being deprecated with the current release and guides them on migrating away from deprecated features to the recommended alternatives.
B: Known issues - This section provides information about any issues or bugs that are known at the time of the release, which might not yet be fixed. It often includes workarounds for these issues if they are available.
Option C, "Next service pack release date," is not typically included because release dates are subject to change and are usually communicated through official channels closer to the actual release.
Option D, "Download link to AEM jar," is not included in the release notes but is typically available through the Adobe Software Distribution site or Cloud Manager for AEM as a Cloud Service.

The request log in AEM records details about requests processed by the AEM instance, including transaction response times. This log is useful for developers when they need to analyze the performance of page requests, including how long each page takes to load. The request log can typically be found in thelogsdirectory of the AEM installation and may be namedrequest.log.
stdout.logtypically contains the standard output of the AEM process and is not specific to request transactions.
audit.logis used to log user actions for auditing purposes and does not include transaction response times.
