• B.Simple List
• C.Lookup with Tabs
• D.Dialog - Advanced Selection

답을 확인하기

정답:
Explanation:
Lookup basic C This is the basic Lookup pattern that has just one list or tree, and also optional custom filters and actions.
Lookup w/tabs C This Lookup pattern is used when more than one view of the lookup can be made available to the user. Tab captions aren't shown. Instead, the tab is selected through a combo box.
Lookup w/preview C This more advanced Lookup pattern enables a preview of the current record in the lookup grid.

What are two benefits of applying a form pattern to a form? Each correct answer presents part of the solution.

• A.ensures data consistency by enforcing common relationship patterns between datasources
• B.provides default values for many properties on controls
• C.enforces a consistent style so that the forms a user encounters are immediately recognizable
• D.allows a developer to create many delivered forms from a base form

답을 확인하기

정답:
Explanation:
Microsoft Dynamics 365 for Finance and Operations, Enterprise Edition, makes development easier by providing a guided experience for applying patterns to forms to ensure they are correct and consistent.
They help validate forms and control structures and the use of controls in certain places. Using patterns also ensures that each new form encountered by a user is immediately recognizable in appearance and function. Form patterns can provide many default control properties, which leads to a more guided development experience.

Question No : 11

A team member who is not familiar with IntelliMorph needs to understand what field groups are and the primary advantage of using them.
What should you tell the team member?

• A.They are groups of fields referenced directly on forms and reports; however, you need to update ans refresh the filed groups on the forms or reports if there are additions or deletions from the table.
• B.They are groupings of fields by data type; field groups allow for the update or data by using indexes to quickly access key columns and rows.
• C.They are groupings of fields on the table; they are used for speeding up the entity of information based on the form for which they are designed.
• D.They are groupings of physical database fields by logical choice; field groups can be referenced directly on forms and reports, and, upon modification, related references are automatically updated.

답을 확인하기

정답:
Explanation:
Field groups: These are logical groupings of physical database fields. So field groups can be referenced directly on forms and reports so that when a modification is made to a field group, related references are automatically updated to reference the new content of the group.

Question No : 12

You are extending primitive data types to make your code more readable, and you need to assign
Extended Data Types (EDT) properties.
Which best practice should you follow?

• A.Do not leave the display length and style an Auto.
• B.Ensure that the HelpText property is the same as the label.
• C.Do not use labels for user interface text.
• D.Ensure that you reference an EDT when creating table fields.

답을 확인하기

정답:
Explanation:
Wherever possible, you should avoid the creation of table fields which don't reference an EDT, as this
makes potential future changes more difficult to implement.

Question No : 13

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 easier navigation.
• B.Set the validate property to No when you are using navigational relationships so that the application is easy 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 relation to Yes.

답을 확인하기

정답:
Explanation:
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.

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 and disk 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.

답을 확인하기

정답:
Explanation:
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.
