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

1. The response time of Decision Center while browsing and editing rule artifacts is slow. What should the application developer do to improve the performance?

A) Tune the JVM maximum heap size.
B) Use an Embedded Derby database.
C) Increase the Execution Unit (XU) connection pool size.
D) Augment the number of Business Object Model (BOM) entries and add more verbalizations.

2. After a company deploys their rules to production, a series of new business policies affect several of the deployed rules. The rule authors fix the rules, and the updated ruleset is deployed.
However, another business policy change makes some of the rule fixes incorrect and the original rules need to be reinstated. The rule authors ask for help from the application developer so that they do not lose their correct changes. What should the application developer do?

A) Erase the current project and synchronize with Rule Designer to get the originally deployed rules.
B) Unfreeze the deployment baseline so the rule authors can fix the rules again, and then redeploy the baseline.
C) Restore the baseline so that it becomes the current state of the project so that the rule authors redo the appropriate rule changes.
D) Clone the deployment baseline to a branch, and use the Diff and Merge tool to select the correct rules to keep on the current branch of the project.

3. CORRECT TEXT
Business users would like the output of a simulation run to be displayed as a pie chart. What should the application developer do to implement this requirement?

A) Implement the interface IlrScenarioSuiteKPIRenderer and repackage the Decision Center EAR file to include this new class.
B) Implement the interface IlrScenarioSuiteResourcesRenderer and repackage the Decision Center EAR file to include this new class.
C) Implement the interface IlrKPIResultAggregator and repackage the Decision Center EAR file to include the new class.
D) Create a custom JSP page that includes pie chart widget and repackage the Decision Center EAR file to include this JSP Page.

4. The Java method Customer.getLastOrderAmt() is verbalized as last order amt} of {this}? and returns the amount of the last customer order. The rule authors decided that ?amt? should be spelled out as ?amount? in rule artifacts. Many rule artifacts already exist using the ?amt? abbreviation. To address the new requirement, the application developer should:

A) use a semantic query with an action to refactor the rule artifacts.
B) rename the Business Object Model (BOM) method and perform a BOM update to refactor the rule projects.
C) use Alt+Shift+R from a rule editor to rename ?amt? to ?amount? and apply refactoring to the rule artifacts.
D) edit the subject used in the verbalization and apply refactoring to the rules.

5. During development, a ruleset that determines the eligibility of an applicant is in the Risk Department's Decision Center repository. The architecture team decides to use the ruleset as a web service generated from a Rule Designer project wizard for other departments in the company to invoke. Which execution approach should the application developer use?

A) Hosted Transparent Decision Service (HTDS)
B) Monitored Transparent Decision Service (MTDS)
C) Hosted Transparent Decision Service with the InterceptorEnabled parameter set to false
D) Remote EJB Rule Session
