The ContentDelivery Network (CDN) is a feature that improves the performance of public sites by caching static content, such as images, CSS files, and JavaScript files, on servers that are closer to the site visitors.
This reduces the load on the Salesforce servers and speeds up the page loading time. CK can enable and configure the CDN from Experience Builder settings.

This option allows CK to use Google as an external identity provider and enable customers to log in to the site using their Google credentials. CK can also access customers' basic profile data, such as name, email, and picture, by specifying the scopes and attributes in the authentication provider settings. CK can also use the authentication provider to configure single sign-on (SSO) and just-in-time (JIT) provisioning for the site.

These license types allow customers to access custom objects and a subset of standard CRM objects, such as accounts, contacts, cases, and dashboards. These license types also support advanced sharing features, such as role hierarchy, sharing rules, manual sharing, and Apex sharing.

This option allows UC to give retail store managers access to the records owned by their peers and subordinates. Super User access is a feature that grants community users access to records that are owned by users who have the same role or a role below them in the role hierarchy. Super User access can be enabled for partner users or customer users with Customer Community Plus or Partner Community licenses2
