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

1. An application developer is preparing to deploy the ruleset that uses a Java Execution Object Model (XOM) to a Java EE environment for remote access, using stateless rule sessions. What should the application developer do to ensure optimal execution performance?

A) Disable Java 2 Security.
B) Change the Execution Unit (XU) traceLevel property from WARNING to FINE on the application server.
C) Set the ruleset property ruleset.sequential.trace.enabled to true.
D) In the ra.xml file, set the transaction-support property to LocalTransaction.

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

3. 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) 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.
C) Unfreeze the deployment baseline so the rule authors can fix the rules again, and then redeploy the baseline.
D) Restore the baseline so that it becomes the current state of the project so that the rule authors redo the appropriate rule changes.

4. A ruleset is deployed to Rule Execution Server and the rule administrators requested that Decision Warehouse be used to store trace information about ruleset executions. What should the application developer do to activate tracing on the already deployed ruleset?

A) Navigate to the ruleset within Rule Execution Server console and add the ruleset.trace.enabled property.
B) Tracing cannot be enabled without deploying the ruleset again with the monitoring.enabled ruleset property set to true.
C) Use the res-deploy Ant task with the correct parameters to enable tracing on the deployed ruleset.
D) Navigate to the ruleset within Rule Execution Server console and click the Show Monitoring Options to enable tracing.

5. CORRECT TEXT
A company wants to run a simulation against millions of database records to evaluate the
business impact. The Rule Execution Server and Scenario Service Provider (SSP) used to run
simulation are deployed on computer with multiple processors. What should the application
developer do to reduce time required to run the simulation?

A) Deploy the SSP onto a application server cluster.
B) Divide the database records into subsets and run the simulation against the subset data.
C) Implement a IlrParallelScenarioProvider
D) Implement IlrScenarioProvider and use multiple threads to run rule session.
