Microsoft MB6-704 Online Questions & Answers

• Question 51:

  You need to identify which permission can be set only on a form that has date effective data. Which permission should you identify?

  A. Correct
  B. Create
  C. Delete
  D. Read
  E. Update
  A. Correct

  ---

  For example, you have a role where you set the PastDataAccess property to Read, the Current- DataAccess to Update, and FutureDataAccess to Delete. The role also includes a privilege that contains a permission to a valid time state table

  where the EffectiveAccess property is set to Cor- rect. As a result, the role has read access to past records, update access to current records, and correct access to future records.

  Note:

  To grant access to the records in a valid time state table, you use the role-based security. You can specify whether a role can view, create, or update records in the table.

  * When you add date effective fields to a form, you use one of the following patterns.

  Show the current value.

  Show a list of editable records.

  Show a read-only list of records.

• Question 52:

  You have a form that uses a grid view. The form has one data source.

  You need to identify when the data entered in the form is committed to the database table. What should you identify?

  A. When the form is compiled
  B. When the focus changes from one row to another row
  C. When the form is synchronized
  D. When the focus changes between fields in the same row
  B. When the focus changes from one row to another row

• Question 53:

  You are developing a solution for a customer.

  You plan to add a local embedded function to perform a recursive operation by using the follow- ing code:

  

  You need to identify which variables can be accessed from mainMethod. Which variables should you identify?

  A. MainMethodParam and embededFunctionParam
  B. MainMethodParam and CounterInMain Method
  C. EmbededFunctionParam and CounterInembeded Function
  D. CounterInMainMethod and CounterInembeded Function
  B. MainMethodParam and CounterInMain Method

  ---

  The variables local to the to embededFunction cannot be accessed by MainMethod.

• Question 54:

  You have the following X++ code: (Line numbers are included for reference only.)

  

  Method l and method2 are in Class l. Method3 is in Class2.

  You need to set the value of vanable3 to the value of variable l from class l Obj.

  Which code segment should you insert at line 22?

  A. Variable3 = classl Obj.methodl();
  B. Variable3 = new Class l{) .variable l;
  C. Variable3 = class l Obj. variable l;
  D. Variable3 = this. variable l ;
  A. Variable3 = classl Obj.methodl();

  ---

  The variable from the other class is only accessible through the method method1.

• Question 55:

  You have a table named Tablel that contains the information from a sales invoice.

  For Tablel, you need to create a method named Tax Amount that will return the total amount of tax for the invoice. The method will be used in a report to show the tax amount information.

  Which type of method should you use?

  A. Static
  B. Accessor
  C. Main
  D. display
  A. Static

  ---

  Static methods, or class methods, belong to a class and are created by using the keyword static.

  They are called by using the following syntax:

  ClassName::methodName();

  You do not need to instantiate an object before you use static methods. Static methods are widely used in Microsoft Dynamics AX to work with data that is stored in tables.

  Reference: Methods in X++ [AX 2012]

• Question 56:

  You have two tables named Table l and Table2. There is a relationship between the tables.

  You need to display data from both tables in a form.

  How should you create the data source for the form?

  A. Add both tables to a perspective and use the perspective as the data source.
  B. Create a new table named Table3 that is related to Table l and Table2. Use Tables as the data source.
  C. Add both tables to a map and use the map as the data source.
  D. Add both tables to a query and use the query as the data source.
  D. Add both tables to a query and use the query as the data source.

  ---

  You can add parent and child data sources to a query. Add multiple data sources to a query

  1.

  In the Application Object Tree (AOT), click Queries, locate the query you want to add data sources to, and then click the query node. For information about create queries, see Accessing Data.

  2.

  Right-click Data Dictionary, and then click Open New Window.

  3.

  Drag a table, map, or view from the new window to the Data Sources node below the query node to add a parent data source.

  4.

  Click the parent data source, and then drag a table, map, or view from the new window to the Data Sources node below the parent data source to add a child data source.

  5.

  Specify how the parent and child data sources are joined by setting the JoinMode property on the child data source

  6.

  Create a relationship between the data sources.

  Reference: How to: Add Multiple Data Sources to a Query [AX 2012]

  Incorrect:

  Not C: Maps define X++ elements that wrap table objects at run time. With a map, you associate a map field with a field in one or more tables. This enables you to use the same field name to ac- cess fields with different names in different

  tables. Map methods enable you to create or modify methods that act on the map fields.

• Question 57:

  You have the following X++ statement:

  

  A. Wrong value of variable B variable.
  B. Wrong value of variable B variable. Process was cancelled.
  C. Variable2 cannot have value greater than 2. Process was aborted.
  D. Process was cancelled. Wrong value of variable B variable.
  A. Wrong value of variable B variable.

  ---

  All variables must be declared before they can be used. When a variable is declared, memory is also allocated and the variable is initialized to the default value. Variable b would be initialized to 0 by default.

  Reference: Declaration of Variables [AX 2012]

• Question 58:

  You have the following X++ code: (Line numbers are included for reference only.)

  

  

  Method l and method2 are in Class l. Method3 is in Class2.

  You need to set variablel for class l Obj to a value of 5.

  Which code segment should you insert at line 21?

  A. classl Obj.methodl(5);
  B. new Classl( ).methodl(5);
  C. classl Obj.variable1 = 5;
  D. this. variable l =5:
  A. classl Obj.methodl(5);

  ---

  All classes are public, but all member variables are implicitly private. Use a public Setter Accessor method, here method1, on Obj1 to change the variable of the other class.

  Example:

  Add a Setter Accessor Method

  Follow these steps to add a method that sets the value of a member variable:

  1.

  Right-click the Class1 node, and then click New > Method.

  2.

  Rename the method1 node to setFirstName.

  3.

  In the code Editor window, paste in the following X++ code for the method.

  X++

  public void setFirstName(str _firstName)

  {

  firstName = _firstName;

  }

• Question 59:

  You plan to create two tables named Table l and Table2. Both tables will have a field named Customer Number of the string type that has a length of 15. The tables will have a relationship on the Customer Number field.

  You need to ensure that the string length of Customer Number is identical for both tables. The solution must ensure that if any relationships on the Customer Number field are added to other tables, the other tables will have the same string

  length for Customer Number.

  What should you use?

  A. A view
  B. An extended data type (EOT)
  C. A perspective
  D. A map
  B. An extended data type (EOT)

  ---

  Extended data types (EDTs) are user-defined types, based on the primitive data types boolean, integer, real, string, and date, and the composite type container. You can also base EDTs on other EDTs.

  The benefits of EDTs are as follows:

  Code is easier to read because variables have a meaningful data type. For example, Name instead of

  

  string.

  The properties you set for an EDT are used by all instances of that type, which reduces work and

  

  promotes consistency. For example, account numbers (AccountNum data type) have the same properties throughout the system. You can create hierarchies of EDTs, inheriting the properties that are appropriate from the parent and

  

  changing the other properties.

  Reference: Extended Data Types (EDTs) [AX 2012]

  Incorrect:

  Not C: A perspective is a collection of tables and views that contain the measures and dimen- sions for a cube.

  Not D: Maps define X++ elements that wrap table objects at run time. With a map, you associate a map field with a field in one or more tables. This enables you to use the same field name to ac- cess fields with different names in different

  tables. Map methods enable you to create or modify methods that act on the map fields.

• Question 60:

  You need to extract the last three characters from the string value of 122018 by using X++ code.

  Which two code segments achieve this goal? Each correct answer presents a complete solution.

  A. = substr('122018', 0,3)
  B. = substr('122018', 4,3)
  C. = substr('122018', 6,-3)
  D. = str2num('122018', 3)
  E. = str2num('122018', -3)
  B. = substr('122018', 4,3)
  C. = substr('122018', 6,-3)

  Subst retrieves part of a string.

  str subStr(str _text, int _position, int _number)

  Parameters:

  _text

  The original string.

  _position

  The position in the original string where the part to retrieve begins.

  _number

  A signed integer that indicates the direction and number of positions to retrieve from the original string. If there is a minus sign preceding _number, the system selects the substring backward from the specified position.

  Incorrect:

  Not d, not E: str2Num converts a string to a real number.

  Syntax: real str2Num(str _text)
