IBM 000-400 Exam Syllabus Topics:

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

1. 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 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.
C) 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.
D) Create 3 ruleflows, set the main flow task property of the main ruleflow to true and set other ruleflows to false.

2. CORRECT TEXT
A company wants to run a simulation against millions of database records to evaluate the
business impact. The Rule Execution Server and Scenario Service Provider (SSP) used to run
simulation are deployed on computer with multiple processors. What should the application
developer do to reduce time required to run the simulation?

A) Deploy the SSP onto a application server cluster.
B) Implement IlrScenarioProvider and use multiple threads to run rule session.
C) Divide the database records into subsets and run the simulation against the subset data.
D) Implement a IlrParallelScenarioProvider

3. A ruleset contains one rule task that uses RetePlus execution mode, and one rule task that uses FastPath. For troubleshooting purposes, the application developer implements logging of the names of all the rules fired for every ruleset execution, using the API IlrSessionRequest.setTraceEnabled(true) and IlrSessionResponse.getRulesetExecutionTrace(). What property should the application developer also configure on the ruleset?

A) ruleset.sequential.trace.enabled = true
B) ruleset.optimization.enabled = false
C) ruleset.bom.enabled = true
D) ruleset.trace.enabled = true

4. An application developer needs to ensure that a set of rules covers all possible cases leaving no gaps. Which artifact should the application developer use to perform this task?

A) Rule project statistics report
B) Ruleset execution trace
C) Consistency analysis report
D) Completeness analysis report

5. A company implemented a report data validation system with business rules. As there is a large volume of data, the design team has decided to run validations in batch and parallel mode. The ruleset will be executed in Java SE and the maximum number of threads executing rules is 20). When an application developer tests the rule execution code, the following exception comes up: ilog.rules.res.session.IlrSessionException: An error occurred while the rule session was called: ilog.rules.res.xu.cmanager.impl.IlrLocalizedResourceAllocationException: Default connection manager pool is full, error code: GBRXU0200E ilog.rules.res.xu.pool.IlrPoolException: Pool of connections is full What should the application developer do to resolve the exception?

A) Edit the resource adapter descriptor file ra.xml to set the pool.maxSize property to 20.
B) Set the ruleset property pool.maxSize to 20.
C) Configure the IlrSessionRequest class to set connection pool size to 20.
D) Set pool size of the Execution Unit (XU) connection factory in the application server to 20.
