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

1. A custom hierarchy property location is defined for each rule to specify geographical location to which the rule applies. The following figure shows the value of the location property for various rules.

An application developer wants to select all rules that apply to Los Angeles. For example, Rule 1, Rule 2 and Rule 3. Which runtime rule selection Business Action Language (BAL) construct should the application developer use?

A) the location of the rule is 'Los Angeles'
B) the location of the rule is under 'Los Angeles'
C) the location of the rule is over 'Los Angeles'
D) the location of the rule is greater than or equal to 'Los Angeles'

2. 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: Sequential Exit Criteria: None
D) Algorithm: Fastpath Exit Criteria: RuleInstance

3. The following user groups are in the Decision Center: ?Authors: can create rules and set the status to defined after authoring is complete ?Testers: can only view rules in defined status and change status to validated after testing is complete ?Deployers: can only view rules in validated status and change status to deployed ?Administrators: have all permissions What mechanism can the application developer use to implement the above governance policy?

A) Implement a rule session interceptor in Decision Center.
B) Use the built-in Decision Center permission management.
C) Set up the user group permissions and implement a session controller in Decision Center.
D) Set up the user group permissions in Decision Center.

4. 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) Disable Java 2 Security.
B) Set the ruleset property ruleset.sequential.trace.enabled to true.
C) In the ra.xml file, set the transaction-support property to LocalTransaction.
D) Change the Execution Unit (XU) traceLevel property from WARNING to FINE on the application server.

5. A Hosted Transparent Decision Service (HTDS) for a car insurance company has the following input and output. Input: A form that includes information about the driver, the vehicle and the type of insurance. Output: The cost of insurance if the request is eligible. How should the application developer implement this flow of information between the calling application and the decision service?

A) Implement a database call that is triggered during rule execution so the rule engine can access all relevant driver, vehicle, and insurance information. Define a ruleset variable to return the decision results.
B) Define three ruleset variables for the application to pass the driver, vehicle, and insurance input objects. Define one ruleset parameter to return the decision results.
C) Implement an IlrContext subclass to populate the working memory with all the driver, vehicle, and insurance objects. Define a ruleset parameter to return the decision results.
D) Define one ruleset parameter to pass the driver, vehicle, and insurance information to the rule engine. Define one ruleset parameter to return the decision results.
