Question #7

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

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

Question #8

Within a pricing application, there are three valid regions: A, B, and C.
The pricing rules currently include this decision table. The current version of this table has a gap in the rules and does not assign a discount for Gold customers in region C.
To prevent this rule from getting deployed in the future, gaps for this decision table should be treated as an error.

What should the application developer do in Rule Designer to treat gaps as an error condition within this decision table?

A. From the column condition builder, turn on check interval for each condition column.

B. From the decision tables properties, turn on gap checking for all condition columns and enforce locking for this table.

C. From the decision tables properties, turn on gap checking for all condition columns and set the reporting of gaps to an error level.

Question #10

A company implemented a report data validation system with business rules. As there is a large volume of data, the design team has decided to run validations in batch and parallel mode. The ruleset will be executed in Java SE and the maximum number of threads executing rules is 20). When an application developer tests the rule execution code, the following exception comes up: ilog.rules.res.session.IlrSessionException: An error occurred while the rule session was called: ilog.rules.res.xu.cmanager.impl.IlrLocalizedResourceAllocationException: Default connection manager pool is full, error code: GBRXU0200E ilog.rules.res.xu.pool.IlrPoolException: Pool of connections is full What should the application developer do to resolve the exception?

A. Set the ruleset property pool.maxSize to 20.

B. Edit the resource adapter descriptor file ra.xml to set the pool.maxSize property to 20.

C. Set pool size of the Execution Unit (XU) connection factory in the application server to 20.

D. Configure the IlrSessionRequest class to set connection pool size to 20.

Question #11

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.inout.filters property to INFO_WORKING_MEMORY=true,WORKING_MEMORY_FILTER=com.test.Customer.

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

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

Question #12

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. Restore the baseline so that it becomes the current state of the project so that the rule authors redo the appropriate rule changes.

C. Unfreeze the deployment baseline so the rule authors can fix the rules again, and then redeploy the baseline.

D. Erase the current project and synchronize with Rule Designer to get the originally deployed rules.
