What should the application developer do?
A. Initialize LineItem instances with a default quantity and ID.
B. Fix the ruleset invocation code to pass non-null Order and LineItem instances.
C. Initialize LineItem instances with a default non-null coupon code.
D. Fix the implementation of the LineItem.toString() method to handle null cases.
正解：C
質問 2：
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. In the ra.xml file, set the asynchronousRulesetParsing property to false to handle concurrent requests.
C. Set the ruleset property ruleset.maxIdleTime to 0 to ensure the ruleset is not removed from cache.
D. Make sure the cache is empty before the first ruleset is parsed.
正解：C

CORRECT TEXT
A company wants to run a simulation against millions of database records to evaluate the
business impact. The Rule Execution Server and Scenario Service Provider (SSP) used to run
simulation are deployed on computer with multiple processors. What should the application
developer do to reduce time required to run the simulation?
A. Implement a IlrParallelScenarioProvider
B. Implement IlrScenarioProvider and use multiple threads to run rule session.
C. Divide the database records into subsets and run the simulation against the subset data.
D. Deploy the SSP onto a application server cluster.
正解：A
質問 4：
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. use Alt+Shift+R from a rule editor to rename ?amt? to ?amount? and apply refactoring to the rule artifacts.
B. use a semantic query with an action to refactor the rule artifacts.
C. edit the subject used in the verbalization and apply refactoring to the rules.
D. rename the Business Object Model (BOM) method and perform a BOM update to refactor the rule projects.
正解：C
