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.bom.enabled = true
• B. ruleset.sequential.trace.enabled = true
• C. ruleset.optimization.enabled = false
• D. ruleset.trace.enabled = true

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. Tracing cannot be enabled without deploying the ruleset again with the monitoring.enabled ruleset property set to true.
• B. Navigate to the ruleset within Rule Execution Server console and add the ruleset.trace.enabled property.
• C. Use the res-deploy Ant task with the correct parameters to enable tracing on the deployed ruleset.
• D. Navigate to the ruleset within Rule Execution Server console and click the Show Monitoring Options to enable tracing.

The Java method Customer.getLastOrderAmt() is verbalized as last order amt} of {this}? and returns the amount of the last customer order. The rule authors decided that ?amt? should be spelled out as ?amount? in rule artifacts. Many rule artifacts already exist using the ?amt? abbreviation. To address the new requirement, the application developer should:

• A. edit the subject used in the verbalization and apply refactoring to the rules.
• B. use Alt+Shift+R from a rule editor to rename ?amt? to ?amount? and apply refactoring to the rule artifacts.
• C. use a semantic query with an action to refactor the rule artifacts.
• D. rename the Business Object Model (BOM) method and perform a BOM update to refactor the rule projects.

The following figure shows the organization of rule project references.
-Project B and Project C reference Project D -Project A references Project B and Project C Where should the application developer define a ruleset parameter so that the parameter is visible in all the rule projects?

• A. Project B
• B. Project C
• C. Project A
• D. Project D

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. 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.
• B. Make sure the cache is empty before the first ruleset is parsed.
• C. In the ra.xml file, set the asynchronousRulesetParsing property to false to handle concurrent requests.
• D. Set the ruleset property ruleset.maxIdleTime to 0 to ensure the ruleset is not removed from cache.
