Explanation:
Box 1: package
An AOT package is a deployment and compilation unit of one or more models that can be applied to an environment. It includes model metadata, binaries, reports and other associated resources. One or more AOT packages can be packaged into a deployable package, which is the vehicle used for deployment of code (and customizations) on demo, sandbox, and production environments.
Box 2: New model
Model - You configure your model to refer to two other models. This enables your model to reference metadata and code elements that are in other packages.
Box 3: project
Project - You create a project and then associate your project to your new model. You add elements to your project, which are also added to your model. Specifically, you add an extended data type (EDT). You also add a table that you populate with fields and a method.
Box 4: deployable package

A: In Microsoft Visual Studio, on the Dynamics 365 menu, expand the Add-ins option, and click Run form patterns report. A background process generates the report. After several seconds, a message box appears in Visual Studio to indicate that the report has been generated and inform you about the location of the Form Patterns report file. You can filter this file by pattern to find forms that use a particular pattern.
D: Right-click Design, point to Apply pattern, and then click Details Master.

Example of Restricted
Suppose we have two tables (Customer & Order) and the relation is of One-To-Many i.e Customer can have many orders.
So on a parent table i.e.(Customer) if I set a delete action property to "RESTRICTED" for Order table. Then If I go and delete the record from a Customer table. It will first check the record in the child table and if exist that warning prompt saying that first we need to delete a record from child table.
Incorrect Answers:
B: Example of Cascade:
Suppose we have two tables (Customer & Order) and the relation is of One-To-Many i.e. Customer can have many orders.
So on a parent table i.e.(Customer) if I set a delete action property to "CASCADE" for Order table. Then If I go and delete the record from a Customer table. It will also delete all the related records in Order table automatically.
C: Example of Cascade + Restricted
Suppose we have three tables (Person ,Customer & Order) Now Person is a parent of Customer table, and Customer is a parent of Order table having (One-To-Many) relations If I set a Delete action property on Person table to "CASCADE" for customer table and If I set a Delete Action property on a CUSTOMER table for Order table to "CASCADE +RESTRICTED".
So if I delete a record from Customer table then It will first check the record in the child table(order table) and if exist that warning prompt saying that first we need to delete a record from child table.
But if I delete a record from Person table it will automatically delete a record in Customer table and all records related to customer table in Order table would also be deleted.

Requirements
General
* You must configure a cloud-based Dynamics 365 Finance development environment and enable code extension that support updates.
* You must configure version control and a Build environment.
* You must migrate all legacy data to the new system.
* You must implement best practices for X++ coding, the data model, caching, and security.
* All new code must be unit tested in a development environment and then validated by the QA team before code is added to source control.
Business processes
* You must configure vendor trade agreements.
* Products must be shipped directly from suppliers to customers depending on customer location to save indirect costs.
* You must collect customer feedback on products shipped directly from vendors.
* You must deploy code to a UAT environment for testing before deploying code to production.
* You must validate all entries for the purchase order creation form.
* You must develop a web portal that allows customers to browse products, place orders, and check order status. Product data for the web portal must be integrated as periodic batches.
Business systems
* You must install and configure a third-party solution for credit card processing within Dynamics 365 Finance. The third-party company will provide a deployable package.
* The workers compensation application must be able to call an API to update worker compensation details in Dynamics 365 Finance.
* You must develop a process to import payroll journals into the system.
* You must configure the warehouse mobile device portal for warehouse operations.
* You must install a third-party solution to support web portal integration. The solution is supplied as a source code model file.
Vendor exclusion list
You must develop a new solution to maintain a Vendor exclusion list for each customer and item combination.
The solution must meet the following requirements:
* Isolate all new vendor exclusion codes as a new assembly by creating a table named VendExclusions.
* Create an index for the table named PrimaryIdx that uses the following fields: CustAccount, ItemId, VendAccount.
* Ensure that users can open the Vendor Exclusion list report from the customer master form. The list must display the customer account, Item ID, and Vendor account fields.
* Implement the Excel integration for the Vendor Exclusion List form.
* Provide functionality to periodically export the Vendor exclusion list to prepare reports by using standard reporting capabilities of Dynamics 365 Unified Operations.

Permissions must be assigned to security roles to match company security model.
* Maintain referential integrity with other tables.
* Users must be presented with a warning message before a direct delivery purchase order is created for a vendor in exclusion list.
