IBM Assessment: 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. 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.
B. In the ra.xml file, set the asynchronousRulesetParsing property to false to handle concurrent requests.
C. Make sure the cache is empty before the first ruleset is parsed.
D. Set the ruleset property ruleset.maxIdleTime to 0 to ensure the ruleset is not removed from cache.
Question 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. Use the built-in Decision Center permission management.
B. Implement a rule session interceptor in Decision Center.
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.
Question 3
Within a pricing application, a function rule artifact needs to be created to do a complex calculation. In what language does the application developer author the function?
A. Business Rule Language Definition Framework (BRLDF)
B. Java
C. Business Action Language (BAL)
D. ILOG Rule Language (IRL)
Question 4
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 general tab, update the preconditions section with gapChecking=true;
C. From the decision tables properties, turn on gap checking for all condition columns and set the reporting of gaps to an error level.
D. From the column condition builder, turn on check interval for each condition column.
Question 5
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.optimization.enabled = false
B. ruleset.bom.enabled = true
C. ruleset.trace.enabled = true
D. ruleset.sequential.trace.enabled = true
