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

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

Question 2

The application developer needs to automate the rule project build process. The rule projects are stored in a Source Code Control system. What should the application developer do to automate the build process?

A. Copy the Rule Designer API library files onto the build machine, write a Java class to call a remotely running Rule Designer to generate the ruleset using the Rule Designer API.
B. Install Rule Designer on the build machine and write a Java class to call the rule engine API.
C. Use the Ant zip task to zip the rule project contents into a ruleset.
D. Install Rule Designer on the build machine and use the Rule Designer build automation tool to generate the ruleset.

Question 3

An application developer needs to create a read-only attribute age in the Business Object Model (BOM) member Customer . The BOM uses a Java Execution Object Model (XOM). What should the application developer add to the XOM member that maps to the BOM member Customer?

A. A method protected int getAge();
B. A method public int getAge();
C. An attribute private int age;
D. A method private int getAge();

Question 4

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 2 ruleflows and set the main flow task property of each ruleflow to true.
B. 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.
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 3 ruleflows, set the main flow task property of the main ruleflow to true and set other ruleflows to false.

Question 5

During development, a ruleset that determines the eligibility of an applicant is in the Risk Department's Decision Center repository. The architecture team decides to use the ruleset as a web service generated from a Rule Designer project wizard for other departments in the company to invoke. Which execution approach should the application developer use?

A. Remote EJB Rule Session
B. Monitored Transparent Decision Service (MTDS)
