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

1. A ruleset contains one rule task that uses RetePlus execution mode, and one rule task that uses FastPath. For troubleshooting purposes, the application developer implements logging of the names of all the rules fired for every ruleset execution, using the API IlrSessionRequest.setTraceEnabled(true) and IlrSessionResponse.getRulesetExecutionTrace(). What property should the application developer also configure on the ruleset?

A) ruleset.bom.enabled = true
B) ruleset.optimization.enabled = false
C) ruleset.trace.enabled = true
D) ruleset.sequential.trace.enabled = true

2. After a company deploys their rules to production, a series of new business policies affect several of the deployed rules. The rule authors fix the rules, and the updated ruleset is deployed.
However, another business policy change makes some of the rule fixes incorrect and the original rules need to be reinstated. The rule authors ask for help from the application developer so that they do not lose their correct changes. What should the application developer do?

A) Clone the deployment baseline to a branch, and use the Diff and Merge tool to select the correct rules to keep on the current branch of the project.
B) Unfreeze the deployment baseline so the rule authors can fix the rules again, and then redeploy the baseline.
C) Erase the current project and synchronize with Rule Designer to get the originally deployed rules.
D) Restore the baseline so that it becomes the current state of the project so that the rule authors redo the appropriate rule changes.

3. The business users require the ability to maintain Business Object Model (BOM) domains using the Decision Center. To address this requirement, the application developer should create:

A) domains of collection type.
B) domains of bounded type.
C) domains from Excel files.
D) domains of static references.

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 monitoring.inout.filters property to INFO_WORKING_MEMORY=true,WORKING_MEMORY_FILTER=com.test.Customer.
B) Set the monitoring.filters property to Customer.largeString1,Customer.largeString2.
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

5. An application developer must implement verbalization changes in a rule project. This rule project:
-is primarily maintained by rule authors in Decision Center which is the source of record ("source
of truth"). -is not present in the application developer's Rule Designer workspace. -does not have any dependency to or from any other rule project. -contains historical versions of rules that should be retained.
What should the application developer do?

A) Create a new "Rule Project from Decision Center" in Rule Designer, implement verbalization changes and publish to Decision Center
B) Publish the rule project to a Rule Solutions for Office RuleDoc, implement rule changes and update Decision Center
C) Choose "Export Current Project State" in Decision Center, import the ".zip" file in Rule Designer, implement verbalization changes, delete the Decision Center rule project and import it back with a ".zip" file exported from Rule Designer
D) Create a new "Rule Project" in Rule Designer, synchronize it with the rule project from Decision Center, implement verbalization changes and publish to Decision Center
