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

1. 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.trace.enabled = true
B) ruleset.optimization.enabled = false
C) ruleset.bom.enabled = true
D) ruleset.sequential.trace.enabled = true

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

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) 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.
B) Erase the current project and synchronize with Rule Designer to get the originally deployed rules.
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) Unfreeze the deployment baseline so the rule authors can fix the rules again, and then redeploy the baseline.

4. A Hosted Transparent Decision Service (HTDS) for a car insurance company has the following input and output. Input: A form that includes information about the driver, the vehicle and the type of insurance. Output: The cost of insurance if the request is eligible. How should the application developer implement this flow of information between the calling application and the decision service?

A) Define one ruleset parameter to pass the driver, vehicle, and insurance information to the rule engine. Define one ruleset parameter to return the decision results.
B) Implement an IlrContext subclass to populate the working memory with all the driver, vehicle, and insurance objects. Define a ruleset parameter to return the decision results.
C) Implement a database call that is triggered during rule execution so the rule engine can access all relevant driver, vehicle, and insurance information. Define a ruleset variable to return the decision results.
D) Define three ruleset variables for the application to pass the driver, vehicle, and insurance input objects. Define one ruleset parameter to return the decision results.

5. A company is developing their insurance claim validation system with business rules. It is required that the latest activated version of the ruleset should be executed when a new ruleset is deployed regardless of the versioning policy. The ruleset will be executed in Java SE. What should an application developer do to satisfy the requirements when implementing rule execution code?

A) Set a unique execution ID with IlrSessionRequest.setExecutionID()
B) Configure the IlrSessionRequest class to set the ruleset path to /RuleAppname/rulesetname.
C) Set the ruleset property ilog.rules.engine.useJIT to true.
D) Edit the resource adapter descriptor ra.xml to set the asynchronousRulesetParsing property to true.
