Explanation
To see certain information about one or more cases when referencing the contact record, an administrator can use two methods: edit the Related List component in the Lightning App Builder and choose Related List as the related list type; and use the page layout editor to include the appropriate column in the Cases related list. The Related List component is a component that allows users to view and edit records related to a parent record on a record page. The Related List component has two types: Related List and Enhanced List. The Related List type shows records in a table format with columns that match the page layout of the parent record. The Enhanced List type shows records in a compact format with fewer columns and actions. To change the type of the Related List component, an administrator can use the Lightning App Builder and select either Related List or Enhanced List from the properties panel. The page layout editor is a tool that allows administrators to control how fields, related lists, buttons, etc., are arranged on a record detail or edit page for each object. To include appropriate columns in a related list, such as case name, case ID, customer name, case reason, case status, and case creation date for cases related to contacts, an administrator can use the page layout editor and drag and drop the desired fields from the palette to the Cases related list on the contact page layout.

Explanation
To identify new leads entered by interns from existing leads, the administrator should define a record type and assign it to the interns. This will allow them to select a different record type when creating leads, and distinguish them from other leads based on record type. Creating a separate Lead Lightning App or updating the active Lead Assignment Rules will not affect lead identification. Setting up Web-to-Lead formwill not work if the interns are entering leads manually in Salesforce.

Explanation
To re-assign cases that meet the 24 hour SLA to the next tier queue, the administrator should use a case escalation rule that defines the criteria for escalating cases, such as age or priority, and the actions to perform when those criteria are met, such as changing owner or sending email alerts. Case escalation rules can help ensure that cases are handled in a timely manner and escalated to appropriate users or queues. Einstein Case Routing, Auto-response rule, and Case assignment rule are not able to re-assign cases based on SLA or age.

Explanation
Validation rule is a tool that can be used to enforce data quality and business logic by preventing users from saving records that do not meet certain criteria. In this case, a validation rule can be created on the Lead object to display an error message if the Lead Status field is marked as qualified and the Budget field is blank.
