Microsoft MB6-704 Online Questions & Answers

• Question 81:

  You have two tables named sales Table and sales Line. Sales Table contains the data shown in the following table.

  

  Sales Line contains the data shown in the following table.

  

  You have the following X++ statement:

  

  A. SO0002 SOO002 SOO003
  B. SOO003 SO0002 SOO003
  C. SOOOOl SOO002 SO0003
  D. SOO002 SO0003 SO0003
  B. SOO003 SO0002 SOO003

  ---

  The output is sorted by the RecID column in the SaleLine Table in descending order, ie 2234569 line first.

• Question 82:

  You are writing logic to fetch data from a database. The logic will use a select statement. You need to identify which keyword to use to fetch a single record from the database. Which keyword should you use?

  A. FirstFast
  B. ForUpdate
  C. Exists
  D. FirstOnly
  D. FirstOnly

  ---

  firstOnly

  Speeds up the fetch. Instructs MorphX to fetch only the first record.

  Example:

  select firstFast custTable

  order by AccountNum;

• Question 83:

  You have a class named Class l that has a public method named methodl.

  For method1, you plan to create an event handler that is defined in the Application Object Tree (AOT).

  For the event handler, you need to develop code that runs after method l executes.

  What should you use to define the code for the event handler?

  A. A display method on a table
  B. A static method on a class
  C. The new method on a class.
  D. A public instance method on a class
  B. A static method on a class

  ---

  All event handlers that subscribe to a method must return void. Event handlers for host methods can use one of two parameter signatures:

  One parameter of the type XppPrePostArgs

  The same parameters that are on the host method that the event handler subscribes to The following code shows an example of an event handler that has the XppPrePostArgs class as the only parameter.

  X++

  static public void myEventHandler(XppPrePostArgs _ppArgs) { // Add useful code here.

  }

  Note:

  *

  In the AOT, you can assign a method as an event handler for the pre-method event or the post- method event of another method. We say the event handler subscribes to an event of the host method. The nodes that represent the subscription of an event handler to a host method are underneath the node for the host method. AOT elements such as classes, tables, and forms can have methods.

  *

  You can subscribe methods as event handlers in two locations in the Application Object Tree (AOT): Under a delegate node

  

  Under a method node

• Question 84:

  You have a table named sales Table that contains the data shown in the following table.

  

  You have the following X++ statement:

  

  You need to identify the output of the X++ statement. What should you identify?

  A. Order3
  B. -Order3
  C. SO0003
  D. SO0003-Order3
  D. SO0003-Order3

  Strfmt formats the specified string and substitutes any occurrences of % n with the nth argument. Syntax: str strFmt(str _string, ...)

  Reference: strFmt Function [AX 2012]

• Question 85:

  You have a table named Table l that contains a string field named Description.

  Users want to search for records in Table l based on words that might be present in Description. The words can be anywhere in the Description field.

  You need to ensure that when the users create queries that are filtered based on the Description field, the query results must be returned in the least amount of time possible. What should you do on Table l?

  A. Create a non-unique index in Description.
  B. Add Description to the AutoSummary field group.
  C. Create a full text index in Description.
  D. Write a find method.
  C. Create a full text index in Description.

  ---

  A full text index contains location information about each significant word in a string field of a table. Some queries can use this information to run more efficiently and complete much sooner. These are queries that search for words that are embedded in the middle of string fields A regular index on a long string field can help a query complete quickly only if the query searches for the word that is at the start of the string field. In X++ SQL this is done with the like keyword and the * wildcard character, such as in the code phrase like "*diamond*".

• Question 86:

  You need to add a menu item to a list page. To which pane should you add the menu item?

  A. Preview
  B. Action
  C. Filter
  D. Fact Box
  B. Action

  ---

  An action pane and action pane strip is a collection of buttons that represent the tasks and opera- tions associated with a Microsoft Dynamics AX form.

  The action pane buttons access menu items that are defined in the AOT.

  When you add a button to an action pane button group, the application object tree (AOT) enables you to select the following types of buttons:

  Command button

  

  Menu item button

  

  Menu button

  

  Button

• Question 87:

  Which two statements accurately describe the characteristics of X++?

  A. Performs automatic garbage collection
  B. Performs runtime checking
  C. Supports method overloading
  D. Supports explicit programmer-defined pointer data types
  A. Performs automatic garbage collection
  B. Performs runtime checking

  ---

  A: The basic strategy of the AX 2012 GC (garbage collection) is the same as it was even before AX 4. AX uses a deterministic GC to manage the lifetime of X++ objects and table buffers. The GC is deterministic in the sense that objects are guaranteed to be disposed from the C++ memory space at the earliest possible moment after they are no longer needed.

  The garbage collector in Dynamics Ax is very simple: it collects all unreferenced object every 3 seconds (ok, this is a little bit simplified, but it's pretty much what the GC does).

  Incorrect:

  Not C: X++ supports overriding, but it does not support overloading. Not D: X++ is an object-oriented language with similarities to C#. The memory management model of X++ is simple. Objects are created with a new operator. There are no

  explicit program- mer-defined pointer data types, and there is no pointer arithmetic.

• Question 88:

  You need to replace a value from a specific position of a container Which function should you use?

  A. ConDel
  B. ConPoke
  C. ConFind
  D. ConNull
  B. ConPoke

  ---

  ConPoke modifies a container by replacing one or more of the existing elements.

  Incorrect:

  Not A: ConDel removes the specified number of elements from a container.

• Question 89:

  You enable a feature for a Dynamics AX instance. What should you use?

  A. An extensible data security (XDS) policy
  B. A configuration key
  C. The Table Permissions Framework (TPF)
  D. A security key
  B. A configuration key

  ---

  The administrator can enable or disable configuration keys to control the features and functional- ity that are available in Microsoft Dynamics AX.

  Reference: Configure application functionality [AX 2012]

  Incorrect:

  Not A: XDS is a powerful mechanism that allows the ability to express and implement complex data security needs.

• Question 90:

  Which three statements accurately describe views in Dynamics AX? Each correct answer presents a complete solution.

  A. A view can be created from a query.
  B. You can update a view by using the Table Browser.
  C. Views can be used to display a subset of the data from the source tables.
  D. The data for the view is refreshed periodically by using a batch job.
  E. The definition of the view is stored in the database when the view is synchronized.
  A. A view can be created from a query.
  C. Views can be used to display a subset of the data from the source tables.

  ---

  A: A view uses a query to retrieve data fields from one or more database tables.

  C: A view enables you to retrieve and return only the data that is relevant for a particular user or scenario. A view can improve performance by returning only relevant fields to the user.

  E: When you create a view, the view definition is generated and stored in the database. When that view is accessed, the view dynamically retrieves the data that satisfies the view definition. Reference: View Basics [AX 2012]
