A ruleset contains one rule task that uses RetePlus execution mode, and one rule task that uses FastPath. For troubleshooting purposes, the application developer implements logging of the names of all the rules fired for every ruleset execution, using the API IlrSessionRequest.setTraceEnabled(true) and IlrSessionResponse.getRulesetExecutionTrace(). What property should the application developer also configure on the ruleset?

• A.  ruleset.sequential.trace.enabled = true
• B.  ruleset.bom.enabled = true
• C.  ruleset.optimization.enabled = false
• D.  ruleset.trace.enabled = true

Within a pricing application, there are three valid regions: A, B, and C.
The pricing rules currently include this decision table. The current version of this table has a gap in the rules and does not assign a discount for Gold customers in region C.
To prevent this rule from getting deployed in the future, gaps for this decision table should be treated as an error.

What should the application developer do in Rule Designer to treat gaps as an error condition within this decision table?

• A.  From the decision tables properties, turn on gap checking for all condition columns and set the reporting of gaps to an error level.
• B.  From the column condition builder, turn on check interval for each condition column.
• C.  From the general tab, update the preconditions section with gapChecking=true;
• D.  From the decision tables properties, turn on gap checking for all condition columns and enforce locking for this table.

An application developer is using Decision Validation Services (DVS) to test business rules. The application developer notices that the required column headings in the generated Excel scenario file template do not contain meaningful text. What should an application developer do to make the column headings meaningful before generating a new scenario file template ?

• A.  Modify the names of the constructor parameters to give them meaningful names.
• B.  Specify meaningful names on the Business Object Model (BOM) members corresponding to the required columns.
• C.  Manually change the column headings in the scenario file template.
• D.  Specify meaningful names for column headings during scenario file template generation.

The Business Object Model (BOM) includes a Customer class with an Age attribute and a Score attribute both of type int. There are three rules and one query:

When the application developer runs Query 1, which rules will be returned?

• A.  Rule 2 and Rule 3
• B.  Rule 1 and Rule 2
• C.  Rule 1 only
• D.  Rule 2 only
• E.  Rule 3 only

There is a RuleApp project called MyRuleApp present in an application developer's Rule Designer workspace. In addition, a ruleset interceptor com.example.MyRulesetInterceptor was implemented for the RuleApp and packaged in the relevant client EAR files. What does the application developer need to do to register the interceptor with Rule Execution Server?

• A.  Set the ruleapp.interceptor.classname property on the RuleApp to com.example.MyRulesetInterceptor.
• B.  Package the ruleset interceptor com.example.MyRulesetInterceptor inside the RuleApp.
• C.  Call the method beforeExecute() during the client code before the ruleset is executed.
• D.  Call the method setInterceptorEnabled() on the session request or session factory instances.
