Three topic types that can be used in an Aura site are:
Standard Topic. This is a topic that is created by users or administrators and assigned to content, such as posts, files, or articles. Users can follow or unfollow standard topics and see the related content on the topic detail page.
Featured Topic. This is a topic that is selected by administrators to highlight important or popular content on the site. Featured topics appear on the home page or on the topic catalog page of the site.
Navigational Topic. This is a topic that is used to organize content into categories or subcategories on the site. Navigational topics appear on the navigation menu of the site and allow users to browse content by topic.

Three items that are reportable by a site administrator through Google Analytics for Experience Cloud sites are B, C, and E. Google Analytics is a tool that allows you to measure and analyze the traffic and behavior of your Experience Cloud site visitors. Google Analytics can report on various items, such as:
Search Activity: This item shows how users search for content on your site, such as the number of searches, the search terms used, the number of results returned, and the click-through rate.
User Login History Option: This item shows how users log in to your site, such as the number of logins, the login methods used, the login duration, and the login frequency.
Contact Support page Activity: This item shows how users interact with your contact support page, such as the number of visits, the bounce rate, the average time on page, and the conversion rate.

Partner Super User access is a feature that allows you to grant access to records owned by other partner users who have the same role or a role below them in the role hierarchy. You can apply Partner Super User access to three objects: Opportunities, Accounts, and Custom Objects.

To support the sharing requirement of using advanced sharing rules for the custom object, CK should grant two user license types to customers: Partner Community User and Customer Community Plus Login User. 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.

The first step to create a site is to enable Digital Experiences in your org. This will allow you to access the Experience Cloud site creation wizard, where you can choose a template, a domain name, and a URL for your site.
