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

Question 1

What can the application developer do to support this requirement?

B. Design a custom report template in Rule Designer with BIRT templates, and publish the report to Decision Center.
C. Design a custom report template in Rule Designer with BIRT templates, then package the BIRT web application with Decision Center libraries.
D. Use the Decision Center Options menu to set additional options so that the report will automatically include those options each time it is generated.

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

Question 3

Question 4

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. Erase the current project and synchronize with Rule Designer to get the originally deployed rules.
B. 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.
C. Unfreeze the deployment baseline so the rule authors can fix the rules again, and then redeploy the baseline.
D. Restore the baseline so that it becomes the current state of the project so that the rule authors redo the appropriate rule changes.

Question 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. Set the ruleset property ruleset.maxIdleTime to 0 to ensure the ruleset is not removed from cache.
B. Make sure the cache is empty before the first ruleset is parsed.
C. In the ra.xml file, set the asynchronousRulesetParsing property to false to handle concurrent requests.
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.
