IBM Assessment: IBM WebSphere Operational Decision Management V8.0, Application Development Sample Questions:
1. An application developer is preparing to deploy the ruleset that uses a Java Execution Object Model (XOM) to a Java EE environment for remote access, using stateless rule sessions. What should the application developer do to ensure optimal execution performance?
A) Change the Execution Unit (XU) traceLevel property from WARNING to FINE on the application server.
B) Disable Java 2 Security.
C) In the ra.xml file, set the transaction-support property to LocalTransaction.
D) Set the ruleset property ruleset.sequential.trace.enabled to true.
2. The Java method Customer.getLastOrderAmt() is verbalized as last order amt} of {this}? and returns the amount of the last customer order. The rule authors decided that ?amt? should be spelled out as ?amount? in rule artifacts. Many rule artifacts already exist using the ?amt? abbreviation. To address the new requirement, the application developer should:
A) use Alt+Shift+R from a rule editor to rename ?amt? to ?amount? and apply refactoring to the rule artifacts.
B) edit the subject used in the verbalization and apply refactoring to the rules.
C) rename the Business Object Model (BOM) method and perform a BOM update to refactor the rule projects.
D) use a semantic query with an action to refactor the rule artifacts.
3. A retail company needs a monthly report that lists only decision tables from all their pricing projects. The business users tried using queries to generate the report, but were unable to capture everything they need into an easy-to-read format, so they asked an application developer for help. What can the application developer do to support this requirement?
A) Use the Decision Center Options menu to set additional options so that the report will automatically include those options each time it is generated.
B) Define a ruleset extractor that extracts the correct set of decision tables, and publish the extractor to Decision Center.
C) Design a custom report template in Rule Designer with BIRT templates, and publish the report to Decision Center.
D) Design a custom report template in Rule Designer with BIRT templates, then package the BIRT web application with Decision Center libraries.
4. A Record instance is passed to the ruleflow as a ruleset parameter. A rule task performs validation and should accumulate all the issues found in the Record. The associated rules have the following characteristics:
-There are numerous action rules and decision tables. ?The rule conditions only involve the
Record class and its attributes. -The rule conditions perform many different tests in various order. -The action part of the rules only adds messages to a list that is not involved in the conditions of the rules.
Which execution settings should the application developer choose for the validation rule task?
A) Algorithm: RetePlus Exit Criteria: RuleInstance
B) Algorithm: RetePlus Exit Criteria: None
C) Algorithm: Fastpath Exit Criteria: RuleInstance
D) Algorithm: Sequential Exit Criteria: None
5. 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.sequential.trace.enabled = true
B) ruleset.trace.enabled = true
C) ruleset.bom.enabled = true
D) ruleset.optimization.enabled = false
