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

1. The Business Object Model (BOM) includes a Customer class with an Age attribute and a Score attribute both of type int. There are three rules and one query:

When the application developer runs Query 1, which rules will be returned?

A) Rule 1 only
B) Rule 2 only
C) Rule 1 and Rule 2
D) Rule 3 only
E) Rule 2 and Rule 3

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) 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

3. A rule task associated with 10 action rules performs elaborate computations on a set of objects. The action part of the rules changes the state of the objects involved in the conditions so that the firing of one rule may cause another rule to fire. For the computation to be correct, the firing of rules should continue until there are no more rules eligible to fire. How should the application developer implement this requirement? Set the rule task algorithm to:

A) Fastpath and check "Update object state" on BOM members as needed
B) Sequential and implement a loop construct in the ruleflow
C) Fastpath and implement a loop construct in the ruleflow
D) RetePlus and check "Update object state" on BOM members as needed

4. Decision Center contains the following:
-Two rule projects: CorporateRiskAssessment and NewYorkRiskAssessment.
-One RuleApp RiskAssessmentRuleApp with a single ruleset CorporateRiskAssessmentRuleset.
An application developer needs to deploy the NewYorkRiskAssessment rule project to Rule
Execution Server as a separate ruleset. Updates to NewYorkRiskAssessment need to be
deployed in a single action with updates to CorporateRiskAssessment. How should the application
developer setup the RuleApp structure in Decision Center to accomplish these requirements?

A) Under Configure > Manage RuleApps, click Deploy to add the NewYorkRiskAssessmentRuleset ruleset.
B) Under Configure > Manage RuleApps, select RiskAssessmentRuleApp and click Edit to add the NewYorkRiskAssessmentRuleset ruleset.
C) Under Configure > Manage RuleApps, click New to create a new NewYorkRiskAssessmentRuleset ruleset.
D) Select the NewYorkRiskAssessment rule project on the Home tab, and under Project > Manage Subbranches and Baselines > Baselines, click New to add the NewYorkRiskAssessmentRuleset ruleset.

5. 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) 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.
C) Set the domainValueProviderName property on the BOM class and integrate the implementation class of interface IlrValueProvider into DecisionCenter.
D) Set the domainValueProviderName property on the BOM class and integrate the implementation class of interface IlrBOMDomainValueProviderinto Decision Center.
