• Question 141:

  A developer submits code for a quality assurance review. Several lines of code use the var data type.

  You need to validate the segments tor the correct X++structure. Which code statement will pass validation?

  A. var var1 = systemDataGet(); var1 = var1 ? today():”Not today”;

  B. var var1 = (var1 >= false) ? true:10;

  C. var var1 = true; var1 = true ? 10:false;

  D. var var1 = true ? 10:“10”;

  Correct Answer: C

• Question 142:

  A company uses Dynamics 365 Finance.

  Two processes attempt to update the same customer record at the same time. One of the updates fails.

  You need to resolve the issue by overriding the table concurrency model.

  Which Select statement should you use?

  A. select firstonly optimisticLock custTable where custTable.AccountNum == '000001';

  B. select firstonly forupdate custTable where custTable.AccountNum == '000001';

  C. select firstonly pessimisticLock custTable where custTable.AccountNum == '000001';

  D. select firstonly firstFast custTable where custTable.AccountNum == '000001';

  Correct Answer: C

  Set the Concurrency Model The concurrency model is set on all tables in the standard application. The majority of tables use optimistic concurrency. You can change these settings, specify settings for your own tables, and specify the concurrency model at a statement level or at a global level.

  To set the concurrency model for a statement, replace the forUpdate keyword in your select statement with optimisticLock or pessimisticLock. This overrules (or enforces) the setting on the table. For example: select pessimisticLock custTable

  where custTable.AccountNum > '1000' If you use the forUpdate keyword, the concurrency model used will be that which was set on the table. Use pessimistic concurrency under the following conditions:

  *

  Update conflicts are likely (otherwise, extra time is used on retries). (Like in this question!)

  *

  Serialization logic exists that requires an update lock on a record in the database. The serializing select statement should include the pessimisticLock keyword. The logic fails if the OccEnabled property is changed on the table.

  Incorrect:

  Not A: Enforce optimistic concurrency in situations where the optimistic model would improve concurrency and throughput when compared with the pessimistic model. For example, where more records are locked than are actually updated.

  Use OCC if a table is never updated or deleted from code but updated only by a client through a form.

• Question 143:

  A company uses Dynamics 365 Finance.

  You are performing a code review for several segments of code that use the Boolean data type.

  You need to validate the segments for the correct X++ structure.

  Which two code statements will compile? Each correct answer presents a complete solution.

  NOTE: Each correct selection is worth one point.

  A. boolean exprValue; exprValue = (8*6 == 48);

  B. boolean exprValue = (8*6 == ‘48’) ? Yes:No;

  C. boolean exprValue; exprValue = (8*6 == 48) ? 1:0;

  D. boolean exprValue = (8*6 == ‘48’) ? false:true;

  Correct Answer: AC

  A: Example:

  // Declares a boolean called exprValue. boolean exprValue;

  // Assigns ExprValue the value of (7*6 == 42), which equates to true.

  exprValue = (7*6 == 42);

  Incorrect:

  Not B, not D: Data type mismatch in 8*6 == ‘48’

• Question 144:

  A company uses Dynamics 365 Finance.

  You implement an extension of a method named calc in ClassA. The calc method:

  1.

  Accepts an integer as an input parameter.

  2.

  Returns an integer as an output parameter.

  You must implement an extension to:

  1.

  Extend the calc method.

  2.

  Prevent the standard code from running if the value of the input parameter is greater than 10.

  You need to implement the correct solution.

  Which code segment should you use?

  

  A. Option A

  B. Option B

  C. Option C

  D. Option D

  Correct Answer: A

  Class extension - Method wrapping and Chain of Command

  Wrapper methods must always call next (not B)

  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. (not D)

  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.

  Incorrect:

  Not B: Need to use the next keyword.

  Not C: Use the if-statement before the next-statement to prevent the standard code to run.

  Not D: Calls to next can't be done conditionally inside an if statement.

• Question 145:

  You develop apps for Dynamics 365 Supply Cham Management.

  You need to track changes only for sales header information by using data entities.

  Which change tracking option should you use?

  A. Enable primary table

  B. Disable change tracking

  C. Enable entire entity

  D. Enable custom query

  Correct Answer: D

  Enable custom query: this option is for a developer to track only a specific set of fields for their custom solution.

  Note 1: An entity can be modeled by using more than one table. The options let you specify the granularity at which changes can be tracked in an entity.

  Enable primary table - Changes that are made to any fields in the primary table trigger a change in entity. Changes that are made to fields in secondary tables don't trigger a change in entity.

  Enable entire entity - Changes that are made to any fields in any table in the entity trigger a change in entity.

  Enable custom query - Uses a custom query that identifies the tables on which changes must be tracked. The custom query is defined in the entity.

  Note: Enable change tracking for non-BYOD scenarios

  Change tracking can be enabled for non-BYOD scenarios. This includes retrieving record changes through Dataverse virtual entities for finance and operations apps. When change tracking is enabled for an entity, changes can be retrieved

  through the entity's OData endpoint by adding odata.track-changes as a preference header.

• Question 147:

  You create a new class.

  Class compilation must fail if a specific method in the source code is called.

  You need to mark the class with the appropriate attribute.

  Which attribute should you use?

  A. SysAppSecurityAttribute

  B. SysTestCategory

  C. SysObsoleteAttribute

  D. SysAttribute

  Correct Answer: C

• Question 148:

  A company uses Dynamics 365 Finance.

  You need to migrate all custom report artifacts from a development environment to a cloud-hosted Tier-1 test environment that has Visual Studio installed.

  Which two actions should you perform? Each correct answer presents part of the solution.

  NOTE: Each correct selection is worth one point.

  A. Apply a deployment package

  B. Export the project as an .axpp file

  C. Create a deployment package

  D. Import the project into a cloud-hosted environment from an .axpp file and ensure that the Overwrite Elements option is selected

• Question 149:

  You are a Dynamics 365 Finance developer. You need to create an extension class. Which action should you perform?

  A. Mark the class as final.

  B. Add the class buffer as the first parameter.

  C. Add the suffix .extension to the file name.

  D. Add the suffix _myextension to the file name.

  Correct Answer: A

  Extension classes are final classes that are adorned with the ExtensionOf attribute and that also have a name that has the _Extension suffix.

  Because the classes are instantiated by the runtime system, it's not meaningful to derive from the extension class. Therefore, the extension class must be marked as final.
