In AEM, what is the role of a live copy page?

The function of a live copy page in Adobe Experience Manager (AEM) is to enable the ability to create and manage content that is linked to an original page, allowing for modifications while keeping the content synchronized with the original. This means that any updates made to the original page can automatically reflect on the live copy, ensuring consistency across different instances of the page.

This feature is particularly useful in scenarios where a company needs to maintain localized versions of content for different markets or regions while ensuring that all those versions are automatically updated when changes occur on the main page. It provides a streamlined workflow for content management, allowing practitioners to efficiently manage variations of content without the need to replicate all updates manually.

The other options do not accurately represent the purpose or functionality of a live copy page in AEM. For instance, duplicating an entire website for backup does not involve the live copy mechanism, managing user roles pertains to permissions and governance rather than content replication, and restricting access to editing is related to user permissions rather than the content management capabilities of live copies.
