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

1. Within a pricing application, there are three valid regions: A, B, and C.
The pricing rules currently include this decision table. The current version of this table has a gap in the rules and does not assign a discount for Gold customers in region C.
To prevent this rule from getting deployed in the future, gaps for this decision table should be treated as an error.

What should the application developer do in Rule Designer to treat gaps as an error condition within this decision table?

A) From the decision tables properties, turn on gap checking for all condition columns and set the reporting of gaps to an error level.
B) From the column condition builder, turn on check interval for each condition column.
C) From the general tab, update the preconditions section with gapChecking=true;
D) From the decision tables properties, turn on gap checking for all condition columns and enforce locking for this table.

2. A bank is developing a loan application system with business rules. An application developer adds a ruleset parameter loanReport of type LoanReport which contains the ?valid? attribute. The application developer needs to initialize the ruleset parameter ?loanReport? and set default value of the valid attribute to ?true? with ILOG Rule Language (IRL) code. How should the application developer do this?

A) Add an Action task node in the ruleflow, and enter the IRL code to set the default value.
B) In the transition that links Start node to the first rule task, enter the IRL code to set the default value.
C) Add a rule task node in the ruleflow and in its Initial Action section enter Business Action Language (BAL) and edit the IRL translation.
D) Set the default value of the loanReport parameter to: new LoanReport(valid=true)

3. Business users manage promotions within Decision Center. To manage the promotions within Decision Center, the user interface needs to be customized with a new Promotion tab on the top menu. What should an application developer to do to register the Promotion tab?

A) Add the tab to the /WEB-INF/teamserver.tld file.
B) Register the tab through Installation Settings Wizard within Decision Center.
C) Add a teamserver:tab tag to /custom/tabs.jsp.
D) Register the tab through modifying the Decision Center configuration parameters in the application server.

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

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