The contact hierarchy is a feature that allows users to view contacts related to an account in a hierarchical tree structure based on their role or position within the account. The contact hierarchy respects record-level access by user, meaning that users can see only those contacts that they have access to based on their profile permissions and sharing settings. The other options are incorrect because contact hierarchy is not limited to
3,000 contacts at one time (it can display up to 5,000 contacts), customizing hierarchy columns does not change the recently viewed contacts list view (it only affects how contacts are displayed in the hierarchy), and sharing settings are not ignored by contacts displayed in the contact hierarchy (they determine which contacts are visible to users).

Master-detail lookup is a type of relationship field that can be used to create a relationship between Account and Shoe and prevent orphaned Shoe records. Master-detail lookup establishes a parent-child relationship between two objects, where the parent record controls certain behaviors of the child record, such as security, ownership, and deletion. If the parent record is deleted, all the child records are deleted as well. References:

To enable users to add repeating tasks in Salesforce, the administrator needs to do two things: first, enable the creation of recurring tasks in activity settings under setup; second, add the create recurring series of tasks field on the page layouts for tasks. This will allow users to create a series of tasks that repeat based on a specified frequency and end date. References:

A lookup field is a type of field that creates a relationship between two objects and allows users to select a record from one object as a value for another object. A lookup relationship creates a one-to-many relationship between two objects, where each parent record can have many child records but each child record can have only one parent record. A lookup relationship also allows limited access to child records, meaning that users can see only those child records that they have access to based on their profile permissions and sharing settings.

A custom profile is a profile that can be created and customized by administrators to define what users can see and do in Salesforce based on their job function or role. It can be used by Cloud Kicks to give read, create, and edit access for objects and restrict users from deleting any records by creating and assigning a custom profile with delete access removed for each object in the object settings. Assigning the standard system administrator profile to analytical user, giving user view all access and assigning them to highest role in role hierarchy, or creating and assigning permission set that includes read, create, and edit access are not solutions for giving read, create, and edit access for objects and restricting users from deleting any records; they either give too much access or do not remove delete access.
