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

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

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

3. Within a pricing application, there are three valid regions: A, B, and C.
The pricing rules currently include this decision table. The current version of this table has a gap in the rules and does not assign a discount for Gold customers in region C.
To prevent this rule from getting deployed in the future, gaps for this decision table should be treated as an error.

What should the application developer do in Rule Designer to treat gaps as an error condition within this decision table?

A) From the decision tables properties, turn on gap checking for all condition columns and enforce locking for this table.
B) From the decision tables properties, turn on gap checking for all condition columns and set the reporting of gaps to an error level.
C) From the column condition builder, turn on check interval for each condition column.
D) From the general tab, update the preconditions section with gapChecking=true;

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

5. Rule authors need to select a city from a drop-down list of more than 1000 cities when editing the condition statement of a rule within Decision Center. An application developer decides to customize the user experience so that the rule authors can search for a city in a popup window. How should the application developer do this?

A) Create a value provider and integrate it into Decision Center.
B) Create a custom business rule language and publish it to Decision Center.
C) Create a value descriptor and integrate it into Decision Center.
D) Create a value editor and integrate it into Decision Center.
