B. Two business action language rules using the else statement in both.
C. A decision table with a precondition, three condition columns, and multiple action columns.
D. A decision table without preconditions, four condition columns, and multiple action columns.
Question 2
An application developer notices that a class in the Java Execution Object Model (XOM) contains a number of methods that should not be imported into the Business Object Model (BOM). How should the application developer annotate the XOM to filter the methods that should not be imported into the BOM?
A. Add the @BusinessName annotation and do not specify a value for the annotation.
B. Add the @NotBusiness annotation.
C. Add the @CustomProperty annotation and set name of the property as import and value as false.
D. Add the @BusinessType annotation and specify null as the business type.
Question 3
An application developer needs to ensure that a set of rules covers all possible cases leaving no gaps. Which artifact should the application developer use to perform this task?
A. Consistency analysis report
B. Rule project statistics report
C. Completeness analysis report
D. Ruleset execution trace
Question 4
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 asynchronousRulesetParsing property to false to handle concurrent requests.
B. Make sure the cache is empty before the first ruleset is parsed.
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. Set the ruleset property ruleset.maxIdleTime to 0 to ensure the ruleset is not removed from cache.
Question 5
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. Set pool size of the Execution Unit (XU) connection factory in the application server to 20.
B. Edit the resource adapter descriptor file ra.xml to set the pool.maxSize property to 20.
C. Configure the IlrSessionRequest class to set connection pool size to 20.
D. Set the ruleset property pool.maxSize to 20.
