IBM Assessment: IBM WebSphere Operational Decision Management V8.0, Application Development Sample Questions:

1. The following user groups are in the Decision Center: ?Authors: can create rules and set the status to defined after authoring is complete ?Testers: can only view rules in defined status and change status to validated after testing is complete ?Deployers: can only view rules in validated status and change status to deployed ?Administrators: have all permissions What mechanism can the application developer use to implement the above governance policy?

A) Implement a rule session interceptor in Decision Center.
B) Use the built-in Decision Center permission management.
C) Set up the user group permissions and implement a session controller in Decision Center.
D) Set up the user group permissions in Decision Center.

2. 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) Java SE with stateful rule session
B) POJO with stateless rule session
C) POJO with stateful rule session
D) Java SE with stateless rule session

3. 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 @CustomProperty annotation and set name of the property as import and value as false.
B) Add the @NotBusiness annotation.
C) Add the @BusinessType annotation and specify null as the business type.
D) Add the @BusinessName annotation and do not specify a value for the annotation.

4. An application developer just activated Decision Warehouse for a ruleset deployed to Rule Execution Server. The ruleset has a Business Object Model (BOM) class com.test.Customer with two large properties: Customer.largeString1 and Customer.largeString2. Activating Decision Warehouse resulted in a decrease in ruleset execution performance. How can the application developer reduce the BOM serialization performance impact and retain the ability to search input and output parameters on the Decision Warehouse tab of the Rule Execution Server Console?

A) Set the ruleset.bom.enabled property to false and in Customer.toString() return a value containing Customer.largeString1 and Customer.largeString2
B) Set the monitoring.filters property to Customer.largeString1,Customer.largeString2.
C) Set the monitoring.inout.filters property to INFO_WORKING_MEMORY=true,WORKING_MEMORY_FILTER=com.test.Customer.
D) Set the monitoring.inout.filters property to Customer.largeString1,Customer.largeString2.

5. 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 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.
B) 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.
C) 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.
D) 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.
