IBM WebSphere Operational Decision Management V8.0 Application Development Sample Questions:

1. An application developer is creating the enumeration LoanType in the Business Object Model (BOM). After creating a new class LoanType in the BOM using the BOM Editor, the application developer notices the following error: [B2X] Cannot find execution class ?LoanType? for translating business class ?LoanType? What should the application developer do to remove this error?

A) Specify LoanType as the execution class.
B) Specify java.lang.String as the execution class.
C) Import the java.lang.String class.
D) Specify java.lang.String as a super class.

2. The design team decided to populate a Business Object Model (BOM) domain from a database and allow the rule authors to reload domain values within Decision Center when the database is updated. What should an application developer do to implement these requirements?

A) Set the domainValueProviderName property on the BOM class and integrate the implementation class of interface IlrValueProvider into DecisionCenter.
B) Change the BOM class to add the virtual method: Collection getValues(IlrClass class) for loading data from the database and generatingdomain values.
C) Add a datasource which connects to the database in application server and configure Decision Center to have a reference to the datasource, and set thedomainValueProviderName property to the datasource name on the BOM class.
D) Set the domainValueProviderName property on the BOM class and integrate the implementation class of interface IlrBOMDomainValueProviderinto Decision Center.

3. A Rule Project was developed in Rule Designer and is ready to be tested. To facilitate troubleshooting of ruleset executions using sample data, the application developer needs to build a custom test harness that embeds a native rule engine and uses the IlrRuleset and IlrContext API. What type of project should the application developer create?

A) RuleApp Project
B) Client Project for RuleApps
C) Rule Project from Decision Center
D) Java Project for Rules

4. A bank is developing a loan application system with business rules. An application developer adds a ruleset parameter loanReport of type LoanReport which contains the ?valid? attribute. The application developer needs to initialize the ruleset parameter ?loanReport? and set default value of the valid attribute to ?true? with ILOG Rule Language (IRL) code. How should the application developer do this?

A) Set the default value of the loanReport parameter to: new LoanReport(valid=true)
B) Add an Action task node in the ruleflow, and enter the IRL code to set the default value.
C) In the transition that links Start node to the first rule task, enter the IRL code to set the default value.
D) Add a rule task node in the ruleflow and in its Initial Action section enter Business Action Language (BAL) and edit the IRL translation.

5. An application developer is validating a rule project in Rule Designer and needs to create a new DVS Excel File Run Configuration. Instead of testing all of the rules, the new run configuration must also specify a subset of the rules to test. Which setting in the run configuration must the application developer apply?

A) On the Extraction tab, select to use an extractor which specifies the rules to test.
B) On the Rules tab, specify the rules to test.
C) On the Excel File tab, click Browse next to Rule Project and specify the rules to test.
D) On the Excel File tab, specify the rules to test.
