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

2. A company is running 20,000 rules in one ruleset and experiences latency during some ruleset executions. No hot deployments are used. After reviewing the execution traces, the application developer recognizes that the performance is affected by reparsing of the same ruleset after overnight inactivity. What should the application developer do to minimize the impact of ruleset parsing and speed up performance?

A) Set the ruleset property ruleset.maxIdleTime to 0 to ensure the ruleset is not removed from cache.
B) In the ra.xml file, set the pool.maxSize parameter to make sure that the number of active rulesets is greater than the size of the XU connection pool.
C) Make sure the cache is empty before the first ruleset is parsed.
D) In the ra.xml file, set the asynchronousRulesetParsing property to false to handle concurrent requests.

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

4. The business users require the ability to maintain Business Object Model (BOM) domains using the Decision Center. To address this requirement, the application developer should create:

A) domains of collection type.
B) domains of bounded type.
C) domains of static references.
D) domains from Excel files.

5. The following user groups are in the Decision Center: ?Authors: can create rules and set the status to defined after authoring is complete ?Testers: can only view rules in defined status and change status to validated after testing is complete ?Deployers: can only view rules in validated status and change status to deployed ?Administrators: have all permissions What mechanism can the application developer use to implement the above governance policy?

A) Set up the user group permissions and implement a session controller in Decision Center.
B) Use the built-in Decision Center permission management.
C) Set up the user group permissions in Decision Center.
D) Implement a rule session interceptor in Decision Center.
