IBM WebSphere Operational Decision Management V8.0 Application Development Sample Questions:
1. There is a RuleApp project called MyRuleApp present in an application developer's Rule Designer workspace. In addition, a ruleset interceptor com.example.MyRulesetInterceptor was implemented for the RuleApp and packaged in the relevant client EAR files. What does the application developer need to do to register the interceptor with Rule Execution Server?
A) Call the method beforeExecute() during the client code before the ruleset is executed.
B) Package the ruleset interceptor com.example.MyRulesetInterceptor inside the RuleApp.
C) Call the method setInterceptorEnabled() on the session request or session factory instances.
D) Set the ruleapp.interceptor.classname property on the RuleApp to com.example.MyRulesetInterceptor.
2. A business analyst requests that Decision Center users who belong to the: ?Manager group can create, update, view, and delete rule artifacts, but cannot update the status of rule artifacts. ?Validator group can view rule artifacts or change their status, but cannot create, update and delete them. How should the application developer set up the Decision Center permissions table to meet these requirements?
A) Option B
B) Option D
C) Option A
D) Option C
3. An application developer collects the following requirements from the business analyst for the case assignment system:
-There are 4 sets of rules to be executed in successive tasks: initialization, preprocess, check
workload and assign case. -The initialization rules should be divided into 5 subsets and orchestrated with 1 ruleflow. -The assign case rules should be divided into 6 subsets and orchestrated with 1 ruleflow.
How should the application developer create the ruleflows?
A) Create 5 ruleflows, set the main flow task property of the main ruleflow to the name of the ruleset and for each other ruleflow set it to name of the ruleflow.
B) Create 2 ruleflows and set the main flow task property of each ruleflow to true.
C) Create 3 ruleflows, set the main flow task property of the main ruleflow to true and set other ruleflows to false.
D) Create 4 ruleflows, set the main flow task property of the main ruleflow to the name of the decision service and for each other ruleflow set it to the label of relevant rule task.
4. An application developer needs to create a read-only attribute age in the Business Object Model (BOM) member Customer . The BOM uses a Java Execution Object Model (XOM). What should the application developer add to the XOM member that maps to the BOM member Customer?
A) A method public int getAge();
B) An attribute private int age;
C) A method protected int getAge();
D) A method private int getAge();
5. 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 monitoring.filters property to Customer.largeString1,Customer.largeString2.
B) Set the monitoring.inout.filters property to INFO_WORKING_MEMORY=true,WORKING_MEMORY_FILTER=com.test.Customer.
C) Set the monitoring.inout.filters property to Customer.largeString1,Customer.largeString2.
D) Set the ruleset.bom.enabled property to false and in Customer.toString() return a value containing Customer.largeString1 and Customer.largeString2
