Which feature can be used to ensure that links on published pages are all valid in AEM?

The Link Checker feature is specifically designed to scan published pages in AEM to identify and validate all hyperlinks contained within those pages. This tool is crucial for maintaining the integrity of content on a website, ensuring that all links lead to active and relevant destinations. It helps prevent users from encountering broken links, which can lead to a poor user experience and diminish the site's credibility.

Using the Link Checker, content authors and site administrators can run checks on the links, identify any that may be broken or misconfigured, and make necessary adjustments to keep the site functioning smoothly. This capability is especially important for maintaining a professional online presence, as it allows proactive management of content and user navigation.

The other options, while possibly related to URL validation in some capacity, do not focus primarily on the comprehensive validation of links within published pages in the way that the Link Checker does. Each of these alternatives serves different roles within AEM or might be limited in their scope regarding ensuring the validity of links across published content.
