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

1. 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 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 ruleset.bom.enabled property to false and in Customer.toString() return a value containing Customer.largeString1 and Customer.largeString2

2. During development, a ruleset that determines the eligibility of an applicant is in the Risk Department's Decision Center repository. The architecture team decides to use the ruleset as a web service generated from a Rule Designer project wizard for other departments in the company to invoke. Which execution approach should the application developer use?

A) Remote EJB Rule Session
B) Monitored Transparent Decision Service (MTDS)
C) Hosted Transparent Decision Service with the InterceptorEnabled parameter set to false
D) Hosted Transparent Decision Service (HTDS)

3. A company is developing their insurance claim validation system with business rules. It is required that the latest activated version of the ruleset should be executed when a new ruleset is deployed regardless of the versioning policy. The ruleset will be executed in Java SE. What should an application developer do to satisfy the requirements when implementing rule execution code?

A) Set a unique execution ID with IlrSessionRequest.setExecutionID()
B) Configure the IlrSessionRequest class to set the ruleset path to /RuleAppname/rulesetname.
C) Edit the resource adapter descriptor ra.xml to set the asynchronousRulesetParsing property to true.
D) Set the ruleset property ilog.rules.engine.useJIT to true.

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

5. 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.
