HOTSPOT (Drag and Drop is not supported)
You are a Dynamics 365 Finance developer. You have the following code: (Line numbers are created for reference only.)


Which values does the info() method return? To answer, select the appropriate option in the answer area.

NOTE: Each correct selection is worth one point.
Hot Area:

  1. See Explanation section for answer.

Answer(s): A

Explanation:




Box 1: SID1234
Parameters
All methods have their own scope. A method can take one or more parameters. Within the scope of the method, these parameters are treated as local variables and are initialized with a value from the parameter in the method call. All parameters are passed by value, which means that you can't change the value of the original variable. You can change only the local variable in the method. This local variable is a copy of the original variable.
Box 2: 5

You are a Dynamics 365 Finance developer.
You have a table named FMVehicle that contains a field named VehicleId. The table has a clustered index named VehicleIdIdx on the VehicleId field. You declare a table buffer named vehicle to refer to the table.

You need to select all records from the FMVehicle table in ascending order based on VehicleId field in the vehicle variable.

Which embedded-SQL statement should you use?

  1. select vehicle index VehicleId;
  2. select vehicle order by VehicleId;
  3. select VehicleId from vehicle order by VehicleId asc;
  4. select vehicle order by VehicleId desc;

Answer(s): B

Explanation:

All select statements use a table variable to fetch records. The results of a select statement are returned in a table buffer variable, here vehicle.

You are a Dynamics 365 Finance and Operations developer. You create a class.
You need to mark the class to ensure that when code is compiled, the process fails if a specific method is called in the source code.

Which attribute should you use?

  1. SysEntryPointAttribute
  2. getAttributes
  3. SysAttribute
  4. SysObsoleteAttribute

Answer(s): D

Explanation:

One use of the SysObsoleteAttribute class is to notify the compiler that the compile should fail if a particular method is called in the source code. The compiler rejects the compile, and displays the specific message that is stored in this use of the attribute.

  2. select vehicle index VehicleIdIdx;
  3. select VehicleId from vehicle order by VehicleIdIdx asc;
  4. select vehicle order by VehicleId desc;

Answer(s): B

Explanation:

The ‘index VehicleIdIdx’ statement will cause an Order By Asc of the fields contained in the index. In this case, that means an Order By Asc of the VehicleID field.

HOTSPOT (Drag and Drop is not supported)
You have a Dynamics 365 Finance environment.
You have the following code: (Line numbers are included for reference only.)

For each of the following statements, select Yes if the statement is true. Otherwise, select No.
NOTE: Each correct selection is worth one point.
Hot Area:

  1. See Explanation section for answer.

Answer(s): A

Explanation:



Box 1: Yes
Class extension - Method wrapping and Chain of Command.
The functionality for class extension, or class augmentation, has been improved. You can now wrap logic around methods that are defined in the base class that you're augmenting. You can extend the logic of public and protected methods without having to use event handlers. When you wrap a method, you can also access public and protected methods, and variables of the base class. In this way, you can start transactions and easily manage state variables that are associated with your class.

Box 2: Yes
In the following example, the wrapper around doSomething and the required use of the next keyword create a Chain of Command (CoC) for the method. CoC is a design pattern where a request is handled by a series of receivers. The pattern supports loose coupling of the sender and the receivers [ExtensionOf(classStr(BusinessLogic1))]
final class BusinessLogic1_Extension
{
str doSomething(int arg)
{
// Part 1
var s = next doSomething(arg + 4);
// Part 2 return s;
}
}

Box 3: Yes
Instance and static methods can be wrapped by extension classes. If a static method is the target that will be wrapped, the method in the extension must be qualified by using the static keyword.

Box 4: No
Wrapper methods must always call next.

Note: Wrapper methods in an extension class must always call next, so that the next method in the chain and, finally, the original implementation are always called. This restriction helps guarantee that every method in the chain contributes to the result.
In the current implementation of this restriction, the call to next must be in the first-level statements in the method body.

Here are some important rules:
-Calls to next can't be done conditionally inside an if statement.
-Calls to next can't be done in while, do-while, or for loop statements.
-A next statement can't be preceded by a return statement.
-Because logical expressions are optimized, calls to next can't occur in logical expressions. At runtime, the execution of the complete expression isn't guaranteed.
