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

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

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

3. An application developer collects the following requirements from the business analyst for the case assignment system:
-There are 4 sets of rules to be executed in successive tasks: initialization, preprocess, check
workload and assign case. -The initialization rules should be divided into 5 subsets and orchestrated with 1 ruleflow. -The assign case rules should be divided into 6 subsets and orchestrated with 1 ruleflow.
How should the application developer create the ruleflows?

A) Create 3 ruleflows, set the main flow task property of the main ruleflow to true and set other ruleflows to false.
B) Create 2 ruleflows and set the main flow task property of each ruleflow to true.
C) Create 4 ruleflows, set the main flow task property of the main ruleflow to the name of the decision service and for each other ruleflow set it to the label of relevant rule task.
D) Create 5 ruleflows, set the main flow task property of the main ruleflow to the name of the ruleset and for each other ruleflow set it to name of the ruleflow.

4. The following figure shows the organization of rule project references.
-Project B and Project C reference Project D -Project A references Project B and Project C Where should the application developer define a ruleset parameter so that the parameter is visible in all the rule projects?

IBM 000-400 Exam

A) Project A
B) Project C
C) Project B
D) Project D

5. 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) 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.
D) Make sure the cache is empty before the first ruleset is parsed.
