IBM A2180-400 問題集

質問 1：
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: RuleInstance
B. Algorithm: Fastpath Exit Criteria: RuleInstance
C. Algorithm: RetePlus Exit Criteria: None
D. Algorithm: Sequential Exit Criteria: None
正解：D

質問 2：
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. Change the BOM class to add the virtual method: Collection getValues(IlrClass class) for loading data from the database and generatingdomain values.
B. Set the domainValueProviderName property on the BOM class and integrate the implementation class of interface IlrValueProvider into DecisionCenter.
C. Set the domainValueProviderName property on the BOM class and integrate the implementation class of interface IlrBOMDomainValueProviderinto Decision Center.
D. 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.
正解：C

質問 3：
A Rule Project was developed in Rule Designer and is ready to be tested. To facilitate troubleshooting of ruleset executions using sample data, the application developer needs to build a custom test harness that embeds a native rule engine and uses the IlrRuleset and IlrContext API. What type of project should the application developer create?
A. Java Project for Rules
B. RuleApp Project
C. Rule Project from Decision Center
D. Client Project for RuleApps
正解：A

質問 4：
A Hosted Transparent Decision Service (HTDS) for a car insurance company has the following input and output. Input: A form that includes information about the driver, the vehicle and the type of insurance. Output: The cost of insurance if the request is eligible. How should the application developer implement this flow of information between the calling application and the decision service?
A. Implement an IlrContext subclass to populate the working memory with all the driver, vehicle, and insurance objects. Define a ruleset parameter to return the decision results.
B. Implement a database call that is triggered during rule execution so the rule engine can access all relevant driver, vehicle, and insurance information. Define a ruleset variable to return the decision results.
C. Define one ruleset parameter to pass the driver, vehicle, and insurance information to the rule engine. Define one ruleset parameter to return the decision results.
D. Define three ruleset variables for the application to pass the driver, vehicle, and insurance input objects. Define one ruleset parameter to return the decision results.
正解：C

質問 5：
A ruleset for validating the content of a message including cross-field validation and business range checking is ready to be integrated into an architecture with only a JVM container. The application must have the capability of providing to and removing from working memory any number of objects without resetting the rule session. Which execution approach should the application developer choose for this application integration?
A. POJO with stateless rule session
B. POJO with stateful rule session
C. Java SE with stateful rule session
D. Java SE with stateless rule session
正解：C
