Two Salesforce recommendations for setting up partner roles in large orgs are B and C. Partner roles are roles that are assigned to partner users who access your Experience Cloud site through a partner account. A partner account is an account that has the Is Partner checkbox enabled. To set up partner roles, you should create them in a separate branch in your Role Hierarchy, which allows you to isolate partner data from internal data and control partner visibility and access. You should also grant partner users access to the partner account using a Sharing Rule, which allows you to share records owned by internal users with partner users based on criteria that you define.

To make Knowledge articles available to site users, you need to map topics to data categories and enable the
"Share on Sites" setting. Topics are labels that you can assign to articles to make them easier to find and organize. Data categories are away of classifying articles based on a predefined hierarchy. You can map topics to data categories, so that when you assign a topic to an article, it automatically inherits the data category visibility settings. The "Share on Sites" setting allows you to share articles with public users on your site.

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 solve these requirements, the administrator should create branding sets, audience targeting, and navigation menu targeting. Branding sets are collections of branding elements, such as colors, fonts, images, and logos, that you can apply to your Experience Cloud site. Audience targeting is a feature that allows you to display pages and components to certain users based on their assigned audience. Navigation menu targeting is a feature that allows you to display different navigation menu items to different users based on their assigned audience. By using these features, the administrator can create different branded experiences for each partner, control the access to the Leads inbox component and the Leads tab, and customize the navigation menu for each partner.

To prevent authenticated external users from searching for Quote and Contract objects but not Opportunity or Asset objects, you need to remove Opportunity and Asset from the object list in the Global Search Result component property editor and the Autocomplete object list in the Search component property editor. The Global Search Result component displays the search results for all objects that match the search term. The Autocomplete object list displays the suggested objects that match the search term as you type. You can customize these components by selecting or deselecting the objects that you want to include or exclude from the search.
