Salesforce Surveys is the best solution for moving existing PROMs surveys to Health Cloud. It allows for question banks and version control for this standardized survey.

A is incorrect because setting Person Accounts to Private is not a valid organization-wide default setting. Person Accounts inherit their sharing settings from Accounts and Contacts.
B is correct because setting Contact to Controlled by Parent ensures that the original business unit that leverages Service Cloud does not have visibility into protected health information (PHI) stored in Contact records. This setting means that the access level for Contact records depends on the access level for their parent Account records.
C is correct because setting related clinical objects to Controlled by Parent or Private ensures that the original business unit that leverages Service Cloud does not have visibility into protected health information (PHI) stored in clinical objects, such as Allergy, Diagnosis, Medication Order, and Procedure Order. These objects are related to either Account or Contact objects, and their sharing settings should match or be more restrictive than their parent objects.
D is incorrect because setting Health Details to Controlled by Parent or Private is not a valid organization-wide default setting. Health Details is a custom object that stores health information for patients and members. It is related to the Person Account object, and its sharing settings are controlled by its parent object.
E is correct because setting Account and Contract to Private ensures that the original business unit that leverages Service Cloud does not have visibility into protected health information (PHI) stored in Account and Contract records. This setting means that users can only access the records that they own or are explicitly shared with them.

C is correct because the dataset required needs to read two SObjects with a clearly defined relationship is a scenario where a single DataRaptor can be used. A DataRaptor Extract can query data from one or more Salesforce sObjects and their related fields using SOQL. A DataRaptor Load can save data to one or more Salesforce sObjects by creating or updating records.

A is correct because administrators can restrict access to patient or member lists using standard Salesforce sharing settings on the list. The Patient List object has an organization-wide default sharing setting that determines the baseline access level for all users in the org. Administrators can also use sharing rules, manual sharing, or Apex managed sharing to grant additional access to specific users or groups.
B is correct because users with profile or permission sets that restrict access to an object cannot create a list using that object. Users need to have at least read access to the objects and fields that they want to use as filters or display columns in their lists. Administrators can check and modify the user's object and field permissions from their profile or permission set.
C is incorrect because administrators cannot restrict access using HCPatientListSecurity custom setting. This custom setting is used to control the visibility of patient or member lists in the Patient List tab, not the access to the lists. Administrators can use this custom setting to specify which lists are visible to which profiles or permission sets, or hide all lists from a profile or permission set.
D is correct because when a user's field-level security restricts access to a field used as a display column, the column does not appear in the list. This is because the field-level security settings override the list settings and prevent the user from viewing the field value. Administrators can check and modify the user's field-level security settings from their profile or permission set.

According to the Health Cloud Data Model Developer Guide, Orders is the underlying object that helps with sales compliance with sales agreements. Orders is a standard object that represents a confirmed request to purchase one or more products. Orders can be used to track the fulfillment and invoicing of products that are sold to customers. Orders can also be linked to contracts or agreements to ensure compliance with the terms and conditions of the sales. Opportunities, Contacts, and Forecasts are not objects that help with sales compliance with sales agreements.
