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

1. A company is running 20,000 rules in one ruleset and experiences latency during some ruleset executions. No hot deployments are used. After reviewing the execution traces, the application developer recognizes that the performance is affected by reparsing of the same ruleset after overnight inactivity. What should the application developer do to minimize the impact of ruleset parsing and speed up performance?

A) In the ra.xml file, set the asynchronousRulesetParsing property to false to handle concurrent requests.
B) Set the ruleset property ruleset.maxIdleTime to 0 to ensure the ruleset is not removed from cache.
C) Make sure the cache is empty before the first ruleset is parsed.
D) In the ra.xml file, set the pool.maxSize parameter to make sure that the number of active rulesets is greater than the size of the XU connection pool.

2. The design team decided to populate a Business Object Model (BOM) domain from a database and allow the rule authors to reload domain values within Decision Center when the database is updated. What should an application developer do to implement these requirements?

A) Set the domainValueProviderName property on the BOM class and integrate the implementation class of interface IlrValueProvider into DecisionCenter.
B) Set the domainValueProviderName property on the BOM class and integrate the implementation class of interface IlrBOMDomainValueProviderinto Decision Center.
C) Add a datasource which connects to the database in application server and configure Decision Center to have a reference to the datasource, and set thedomainValueProviderName property to the datasource name on the BOM class.
D) Change the BOM class to add the virtual method: Collection getValues(IlrClass class) for loading data from the database and generatingdomain values.

3. 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) 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.
B) 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.
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.

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

5. Business users want to be notified when a RuleApp has been updated or deleted. What should the application developer do to support this requirement?

A) Create a Rule Execution Server MBeans listener.
B) Execute the res-jar Ant task to set up email notifications.
C) Register the business user's email in RuleApp view page in Rule Execution Server Console.
D) Register the business user in the Decision Center Console.
