Microsoft MB6-704 Online Questions & Answers

• Question 31:

  Which elements can contain X++ methods?

  A. Info parts
  B. Tables
  C. Enumerators
  D. Extended data types (EDTs)
  B. Tables

  ---

  Every table object has instance methods that can be categorized as either system-defined or ap- plication- defined.

  Tables in Microsoft Dynamics AX have a number of system-defined methods, such as insert, validateField, validateWrite.

  Note:

  Methods can be created on many kinds of items in the AOT other than just classes. The list in- cludes the following:

  Maps

  

  Views

  

  Data Sets

  

  Forms

  

  Queries

• Question 33:

  You have two data sources named Items and Item Details. There is a relationship between the data sources. Item Details contains detailed information about each item in Items. You plan to create a form that contains two grids.

  You need to configure the form to display the details of an item when the item is selected.

  What should you set?

  A. The Link Type of Items
  B. The Join Source of Items
  C. The Link Type of Item Details
  D. The Join Source of Item Details
  D. The Join Source of Item Details

  ---

  Item Details is the Child data source. We set the Join Source on the Item Details to Items. See step 5 below.

  Note:

  You can use form data sources to join tables that create a parent/child relationship between data records. Typically, the records from the data sources are visually separated on the form. For ex- ample, you use a grid to list order records and

  a second grid that us lists the order lines associated with each order. The following steps show how to add and join the tables.

  To Join Data Sources that Create Parent/Child Links

  1.

  In the AOT, expand the form, and then expand the Data Sources node.

  2.

  Press CTRL-D to open a second AOT, expand Data Dictionary, and then expand Tables. The AOT lists the tables you can use as a form data source.

  3.

  To add tables to the form data source, drag two tables and drop each table on the Data Sources node of the form in the first AOT. The tables are added as data sources to the form.

  4.

  Identify the table you will use as the parent data source. The other table will be the child data source.

  5.

  Set the JoinSource property on the child data source to the name of the parent data source.

  6.

  Set the LinkType property of the child data source to Active, Passive, or Delayed. The LinkType property specifies how to update the child data source in response to a change in the parent data source.

  7.

  Create the form design, and then add fields from each data source to the form. Typically, you add two grid controls. One grid displays fields from the parent data source. The second grid displays fields from the child data source. Reference: How to: Join Parent/Child Data Sources for a Form [AX 2012]

• Question 34:

  You need to set up the context for an extensible data security (XDS) policy.

  Which security element should you use?

  A. Permission
  B. Duty
  C. Role
  D. Privilege
  C. Role

  ---

  Concepts of the XDS model include:

  Context:

  A policy context controls the circumstances under which a given policy applies. The policy is not enforced unless the context is set.

  The types of policy contexts are as follows:

  *

  Role context can enable policies that are based on the roles to which the user is assigned.

  *

  Application context can enable policies that are based on information which is set by the ap- plication.

• Question 35:

  You need to identify how the Application Object Server (AOS) implements Code Access Secu- rity to prevent secured APIs from being invoked by untrusted code.

  Which three verifications are performed by the AOS? Each correct answer presents part of the solution.

  A. That the assert is executed on the multiple tiers from the secured class
  B. That the code asserts the appropriate permission on the call stack to use the secured class
  C. That the assert is executed in trusted code and saved in the Application Object Tree (AOT)
  D. That the assert is executed on the same tier as the secured class
  E. That the assert modifies the client only invocations of the secured class
  C. That the assert is executed in trusted code and saved in the Application Object Tree (AOT)
  D. That the assert is executed on the same tier as the secured class
  E. That the assert modifies the client only invocations of the secured class

  ---

  Call a CAS-enabled API

  1.

  Declare a variable for the relevant permission class.

  2.

  Create a new instance of the class.

  3.

  Request permission by using the assert method on the permission class.

  4.

  Revert the assertion (to limit the scope of the permission) after the CAS-enabled API has been used; optional. Permission is automatically reverted when the method finishes executing.

• Question 36:

  You are developing X++ code to update multiple records as a single transaction. The records are located in several tables.

  You need to ensure that if an update of one of the records falls, none of the records update.

  What should you use?

  A. Try and catch
  B. Tts begin and tts commit
  C. Insert record set and tts abort
  D. For update and tts abort
  B. Tts begin and tts commit

  ---

  ttsLevel Checking

  This check ensures that no record can be updated or deleted except from within the same transac- tion scope as it was selected for update. Integrity is ensured by using the following statements:

  *

  ttsBegin: marks the beginning of a transaction. This ensures data integrity, and guarantees that all updates performed until the transaction ends (by ttsCommit or ttsAbort) are consistent (all or none).

  *

  ttsCommit: marks the successful end of a transaction. This ends and commits a transaction. MorphX guarantees that a committed transaction will be performed according to intentions.

  *

  ttsAbort: allows you to explicitly discard all changes in the current transaction. As a result, the database is rolled back to the initial state--nothing will have been changed. Typically, you will use this if you have detected that the user wants to break the current job. Using ttsAbort ensures that the database is consistent.

• Question 37:

  Which three tasks are performed by an Application Object Server (AOS)? Each correct answer presents a complete solution.

  A. Manages client sessions
  B. Stores the Dynamic AX models
  C. Enforces security for Dynamic AX data and features
  D. Runs the X++- code
  E. Hosts help files
  A. Manages client sessions
  B. Stores the Dynamic AX models
  D. Runs the X++- code

  An Application Object Server (AOS) is a core component of the Microsoft Dynamics AX 2012 installation and is installed by using Setup. An AOS enforces security, manages connections be- tween clients and the database, and provides the

  foundation where Microsoft Dynamics AX busi- ness logic is executed.

  The following diagram shows the AOS architecture.

• Question 38:

  You have a class named Class l that contains a static method named smethodl and an instance method named method2. Class l contains the following X+ + code: (Line numbers are included for reference only.)

  

  You need to call smethodl from method2.

  Which code segment should you insert at line 10?

  A. Class l.smethodl()
  B. Class l::smethod l ()
  C. This::smethodl()
  D. This.smthod l()
  B. Class l::smethod l ()

  ---

  Calling a Static Method In the following example, there is no need to first construct an instance of the SoftwareKey class before you call a static method on the class. To call the static method validateSoftwareKey, the syntax starts with the name of the class that contains the method. A pair of colon (::) characters is used to connect the class name to the static method name. boolean yourBool = SoftwareKey::validateSoftwareKey (yourSoftwareKeyString);

  Reference: Static Methods [AX 2012]

• Question 39:

  You have three tables named Table l, Table2, and Table3. Table2 and Table3 extend from Table You define a method on Table2 and you define a field on Table l. You need to identify on which tables the field and the method will be available. Which two options should you identify? Each correct answer presents part of the solution.

  A. The field will be available on Table l only.
  B. The field will be available on Table l, Table2, and Table3.
  C. The method will be available on Table2 and Table3 only.
  D. The method will be available on Table2 only.
  E. The method will be available on Table l, Table2, and Table3.
  B. The field will be available on Table l, Table2, and Table3.
  D. The method will be available on Table2 only.

  ---

  A table can extend from or derive from another table. Each table has the SupportInheritance property and the Extends property, which together control table inheritance. Reference: Table Inheritance Overview [AX 2012]

• Question 40:

  You are developing a solution to store sales orders in Dynamics AX. Each sales order can con- tain multiple sales order lines. A sales order line can be part of only one sales order.

  You create two tables named Sales Table and Sales Line. The tables will model the sales order and the sales order line entities. Sales Table will store sales orders and Sales Line will store sales order lines.

  You need to specify the relationship between the tables.

  Which relationship should you specify?

  A. A foreign key relationship from Sales Table to Sales Line
  B. A field fixed relationship from Sales Table to Sales Line
  C. A foreign key relationship from Sales Line to Sales Table
  D. A related field fixed relationship from Sales Line to Sales Table
  C. A foreign key relationship from Sales Line to Sales Table

  ---

  Create a foreign key relationship in the Sales Line, which is on in many-side of the relationship, to the Sales table, which is on the one-side of the one-to-many relationship.
