Question 1

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 general tab, update the preconditions section with gapChecking=true;

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

Correct Answer: D

Question 2

The design team decided to populate a Business Object Model (BOM) domain from a database and allow the rule authors to reload domain values within Decision Center when the database is updated. What should an application developer do to implement these requirements?

A. Add a datasource which connects to the database in application server and configure Decision Center to have a reference to the datasource, and set thedomainValueProviderName property to the datasource name on the BOM class.

B. Set the domainValueProviderName property on the BOM class and integrate the implementation class of interface IlrValueProvider into DecisionCenter.

C. Set the domainValueProviderName property on the BOM class and integrate the implementation class of interface IlrBOMDomainValueProviderinto Decision Center.

D. Change the BOM class to add the virtual method: Collection getValues(IlrClass class) for loading data from the database and generatingdomain values.

Correct Answer: C

Question 3

A business analyst requests that Decision Center users who belong to the: ?Manager group can create, update, view, and delete rule artifacts, but cannot update the status of rule artifacts. ?Validator group can view rule artifacts or change their status, but cannot create, update and delete them. How should the application developer set up the Decision Center permissions table to meet these requirements?

A. Option D

B. Option C

C. Option A

D. Option B

Correct Answer: C

Question 4

The rule 'NewYearDiscount' was introduced to apply a 30% discount based on quantity purchased and coupon code for the store items with id 1000, 1001 and 1002. The IRL for the rule is as follows:

What should the application developer do?

A. Fix the ruleset invocation code to pass non-null Order and LineItem instances.

B. Fix the implementation of the LineItem.toString() method to handle null cases.

C. Initialize LineItem instances with a default quantity and ID.

D. Initialize LineItem instances with a default non-null coupon code.

Correct Answer: D

Question 5

An application developer is using Decision Validation Services (DVS) to test business rules. The application developer notices that the required column headings in the generated Excel scenario file template do not contain meaningful text. What should an application developer do to make the column headings meaningful before generating a new scenario file template ?

A. Specify meaningful names on the Business Object Model (BOM) members corresponding to the required columns.

B. Manually change the column headings in the scenario file template.

C. Specify meaningful names for column headings during scenario file template generation.

D. Modify the names of the constructor parameters to give them meaningful names.

Correct Answer: D

Question 6

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

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

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

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