質問 1：
A company is running 20,000 rules in one ruleset and experiences latency during some ruleset executions. No hot deployments are used. After reviewing the execution traces, the application developer recognizes that the performance is affected by reparsing of the same ruleset after overnight inactivity. What should the application developer do to minimize the impact of ruleset parsing and speed up performance?
A. Set the ruleset property ruleset.maxIdleTime to 0 to ensure the ruleset is not removed from cache.
B. In the ra.xml file, set the asynchronousRulesetParsing property to false to handle concurrent requests.
C. In the ra.xml file, set the pool.maxSize parameter to make sure that the number of active rulesets is greater than the size of the XU connection pool.
D. Make sure the cache is empty before the first ruleset is parsed.
正解：A

質問 2：
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. Initialize LineItem instances with a default non-null coupon code.
B. Fix the ruleset invocation code to pass non-null Order and LineItem instances.
C. Fix the implementation of the LineItem.toString() method to handle null cases.
D. Initialize LineItem instances with a default quantity and ID.
正解：A

質問 3：
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.
正解：D

質問 4：
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.optimization.enabled = false
B. ruleset.bom.enabled = true
C. ruleset.trace.enabled = true
D. ruleset.sequential.trace.enabled = true
正解：D

質問 5：
Decision Center contains the following:
-Two rule projects: CorporateRiskAssessment and NewYorkRiskAssessment.
-One RuleApp RiskAssessmentRuleApp with a single ruleset CorporateRiskAssessmentRuleset.
An application developer needs to deploy the NewYorkRiskAssessment rule project to Rule
Execution Server as a separate ruleset. Updates to NewYorkRiskAssessment need to be
deployed in a single action with updates to CorporateRiskAssessment. How should the application
developer setup the RuleApp structure in Decision Center to accomplish these requirements?
A. Select the NewYorkRiskAssessment rule project on the Home tab, and under Project > Manage Subbranches and Baselines > Baselines, click New to add the NewYorkRiskAssessmentRuleset ruleset.
B. Under Configure > Manage RuleApps, select RiskAssessmentRuleApp and click Edit to add the NewYorkRiskAssessmentRuleset ruleset.
C. Under Configure > Manage RuleApps, click New to create a new NewYorkRiskAssessmentRuleset ruleset.
D. Under Configure > Manage RuleApps, click Deploy to add the NewYorkRiskAssessmentRuleset ruleset.
正解：B
