문제 #1

The response time of Decision Center while browsing and editing rule artifacts is slow. What should the application developer do to improve the performance?

A. Augment the number of Business Object Model (BOM) entries and add more verbalizations.
B. Tune the JVM maximum heap size.
C. Increase the Execution Unit (XU) connection pool size.
D. Use an Embedded Derby database.

문제 #2

A Record instance is passed to the ruleflow as a ruleset parameter. A rule task performs validation and should accumulate all the issues found in the Record. The associated rules have the following characteristics:
-There are numerous action rules and decision tables. ?The rule conditions only involve the
Record class and its attributes. -The rule conditions perform many different tests in various order. -The action part of the rules only adds messages to a list that is not involved in the conditions of the rules.
Which execution settings should the application developer choose for the validation rule task?

A. Algorithm: RetePlus Exit Criteria: None
B. Algorithm: Fastpath Exit Criteria: RuleInstance
C. Algorithm: RetePlus Exit Criteria: RuleInstance
D. Algorithm: Sequential Exit Criteria: None

문제 #3

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. Use the res-deploy Ant task with the correct parameters to enable tracing on the deployed ruleset.
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 click the Show Monitoring Options to enable tracing.
D. Navigate to the ruleset within Rule Execution Server console and add the ruleset.trace.enabled property.

문제 #4

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 set the reporting of gaps to an error level.
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 enforce locking for this table.

문제 #5

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. Change the BOM class to add the virtual method: Collection getValues(IlrClass class) for loading data from the database and generatingdomain values.
C. Set the domainValueProviderName property on the BOM class and integrate the implementation class of interface IlrBOMDomainValueProviderinto Decision Center.
D. Set the domainValueProviderName property on the BOM class and integrate the implementation class of interface IlrValueProvider into DecisionCenter.
