Which of the following features allows authors to manage content updates on different instances?

Content Synchronization is the feature that allows authors to manage content updates across different instances effectively. This functionality enables the seamless transfer of content changes from one environment, like a development or staging environment, to another, such as production. By using content synchronization, authors can ensure that all instances have the latest updates, which is particularly important in scenarios where multiple teams may be working on the same content or projects simultaneously. This helps maintain consistency and accuracy across the various environments.

Draft and Review Workflow primarily focuses on the process of content creation, editing, and approval within a single instance, rather than managing content across multiple instances. Translation Management deals with the localization of content but does not specifically address updates across different environments. Version Control is crucial for tracking changes and managing multiple iterations of content but does not inherently manage synchronization across different instances. Thus, while all the other options have valuable roles in content management, it is Content Synchronization that specifically addresses the need for managing updates across different instances.
