NEW QUESTION 11
You are adding a relationship to a table.
Which two best practices should you follow? Each correct answer presents part of the solution.

• A. Define a navigational relationship; the validate property on the relation should be set to "Yes" for easiernavigation.
• B. Set the validate property to No when you are using navigational relationships so that the application iseasy to navigate.
• C. Name the relationship with an "_rel" suffix in order to differentiate it from the index that is appended with "_idx".
• D. Define the relationship to a foreign key on the child table by setting the validate property on the relationto Yes.

Answer: BD

Explanation: Section: Develop new elements by using Application Explorer (20-25%)
Explanation/Reference:
Name
The name of a relation should be postfixed with the name of the table it relates to. For example,
CustBankAccounts could be a relation on the BankAccounts table.
If there is only one relation for a table, you can just use the table name for the relation instead.
Relations in the Data Model
A relation should be defined on the table that is holding the foreign key to the relating table.
The Validate
property must be set to Yes.
The system guarantees that data entered in the database fulfills the specified relations. The Self Relation
If a table has a key, the key must be defined by using relations. Such a relation is called the 'self relation'.
The self relation should not be set up in situations where the fields in the key are all foreign keys (such as
relations to other tables) - or more specifically, where the last field in the self relation is a foreign key.
Navigational Relations
Navigational relations are definitions of relations that exist among data in tables where there are no integrity constraints.
Defining a navigational relation benefits the system’s Auto Join system when one form is opened from within another form.
Define navigational relations to make it easy to navigate in the application by using related information.
A navigational relation has the Validate property set to No.
The Auto Join system uses relations that are defined at both the involved tables, which means that you only have to define a navigational relation on the one table to the other to make the Auto Join system work both ways.
Configuration Keys
The configuration key that is specified for the field in a relation must be the same key, or in the same tree
of keys, as the key used for the related field. If the external field in a relationship can be removed, due to
configuration key settings, and the field on which the relation is set is not also removed, you will get a best practices warning.

NEW QUESTION 12
You are writing a JSON-based custom service to consume a new data entity. You need to expose the data entity to the OData service.
What should you do on the data entity to achieve this goal?

• A. Set the PrimaryKey to EntityKey.
• B. Set the Visible property to Yes.
• C. Set the IsPublic property to Yes.
• D. Set the DataManagementEnabled to Yes.

Answer: C

Explanation: Section: Manage the User Interface and Security for Developers (20-25%) Explanation
Explanation/Reference:
OData entities in Dynamics 365 for Finance and Operations are based on the concept of an updatable view. When the public property for an updatable view is set to true, this view is exposed as a top level
OData entity.

• C. a tile item in the model
• D. a resource item in the model

Answer: D

Explanation: Section: Develop new elements by using Application Explorer (20-25%)

NEW QUESTION 14
You are a developer for an Independent Software Vendor (ISV).
You need to create new extended data types in Microsoft Dynamics 365 for Finance and Operations.
What are two best practices for extending a series of data types? Each correct answer presents a complete solution.

• A. An EDT should be created for each atomic entity being utilized.
• B. Subtypes are not required for EDTs that do not contain any property changes.
• C. You cannot extend the recID or tableID system data types.
• D. You cannot use EDTs if one of them is a member of the parent extended data.

Answer: AB

Explanation: Section: Develop new elements by using Application Explorer (20-25%)
Explanation/Reference:
Whenever possible, you will want to use EDTs and EDTs should be created for each atomic entity in the situation that your application is modeling. You should only create subtypes when they are needed. In other words, when you are creating an EDT that
extends another EDT, but you aren't changing any of its properties, you probably do not need to create a new subtype.

NEW QUESTION 17
You need to explain to a team member the difference between TempDB and InMemory table types.
In which three ways do TempDB table types differ from InMemory table types for reporting? Each correct answer presents part of the solution.

• A. TempDB tables have a persistent database schema, and the data is deleted when the table goes out of scope.
• B. TempDB tables are created and destroyed upon use, which not take any database schema space.
• C. TempDB tables are for the storage of large data sets and do not allow exchanging between RAM anddisk space.
• D. TempDB tables are used for small data sets that are under 128 KB in size.
• E. TempDB tables are used when you are unsure of the size of the data set returned.

Answer: ACE

Explanation: Section: Develop new elements by using Application Explorer (20-25%) Explanation
Explanation/Reference:
Temp DB tables have a persistent schema in the database, but they are configured to delete table data when references to the table go out of scope.
An important thing to remember about in-memory tables is that once the table size exceeds 128 kilobytes, the system begins to allocate additional space between the RAM and disk space, which can cause performance to suffer. Because of this, it is recommended to use temp DB tables to handle larger temporary datasets.
Temp DB tables are often used to store data from reports, as report data is usually temporary and that it is not needed after the report is closed.
