Exam AD0-E123 Topic 2 Question 50 Discussion

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.
