NEW QUESTION 1
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 2

NEW QUESTION 4
You manage package deployments for a Microsoft Dynamics 365 Retail environment, and you need to
determine if a package rebuild is necessary. Which scenario requires a package rebuild?

• A. You want to re-run a build due to warnings that appear in the Error List pane concerning best practices.


• B. You want to force a build of all objects, regardless of whether they have changed.


• C. You want to build dependent and reference models at the same time.


• D. You cannot set the Synchronize database on the Build Property to True.

Answer: B

Explanation:
Section: Develop and extend retail components (15-20%) Explanation
Explanation/Reference:
The rebuild will perform a full compile, which will take a bit longer. The rebuild option combines the clean and build steps so we don't have to separately run clean and build.

NEW QUESTION 5
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.

Which two steps are recommended when creating the label? Each correct answer presents part of the solution.

• A. Search for the text of the new label to ensure there are no duplicates.


• B. Give the new label a meaningful Label ID after clicking the New button.


• C. Use all capital letters and numbers for the Label ID of the new label.
