IBM WebSphere Operational Decision Management V8.0 Application Development

Question 1

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. Edit the resource adapter descriptor ra.xml to set the asynchronousRulesetParsing property to true.

C. Configure the IlrSessionRequest class to set the ruleset path to /RuleAppname/rulesetname.

D. Set the ruleset property ilog.rules.engine.useJIT to true.

Correct Answer: C

Question 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 an Action task node in the ruleflow, and enter the IRL code to set the default value.

B. In the transition that links Start node to the first rule task, enter the IRL code to set the default value.

C. Add a rule task node in the ruleflow and in its Initial Action section enter Business Action Language (BAL) and edit the IRL translation.

D. Set the default value of the loanReport parameter to: new LoanReport(valid=true)

Correct Answer: A

Question 3

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 three ruleset variables for the application to pass the driver, vehicle, and insurance input objects. Define one ruleset parameter to return the decision results.

B. 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.

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. 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.

Correct Answer: B

Question 4

An application developer collects the following requirements from the business analyst for the case assignment system:
-There are 4 sets of rules to be executed in successive tasks: initialization, preprocess, check
workload and assign case. -The initialization rules should be divided into 5 subsets and orchestrated with 1 ruleflow. -The assign case rules should be divided into 6 subsets and orchestrated with 1 ruleflow.
How should the application developer create the ruleflows?

A. Create 4 ruleflows, set the main flow task property of the main ruleflow to the name of the decision service and for each other ruleflow set it to the label of relevant rule task.

B. Create 5 ruleflows, set the main flow task property of the main ruleflow to the name of the ruleset and for each other ruleflow set it to name of the ruleflow.

C. Create 2 ruleflows and set the main flow task property of each ruleflow to true.

D. Create 3 ruleflows, set the main flow task property of the main ruleflow to true and set other ruleflows to false.

Correct Answer: D

Question 5

Given the rules under Append 1, and the scenarios under Append 2, what are the correct expected results?

A. Option D

B. Option B

C. Option A

D. Option C

Correct Answer: D

Question 6

An application developer just activated Decision Warehouse for a ruleset deployed to Rule Execution Server. The ruleset has a Business Object Model (BOM) class com.test.Customer with two large properties: Customer.largeString1 and Customer.largeString2. Activating Decision Warehouse resulted in a decrease in ruleset execution performance. How can the application developer reduce the BOM serialization performance impact and retain the ability to search input and output parameters on the Decision Warehouse tab of the Rule Execution Server Console?

A. Set the ruleset.bom.enabled property to false and in Customer.toString() return a value containing Customer.largeString1 and Customer.largeString2

B. Set the monitoring.filters property to Customer.largeString1,Customer.largeString2.

C. Set the monitoring.inout.filters property to INFO_WORKING_MEMORY=true,WORKING_MEMORY_FILTER=com.test.Customer.

D. Set the monitoring.inout.filters property to Customer.largeString1,Customer.largeString2.
