問題 #1

A Record instance is passed to the ruleflow as a ruleset parameter. A rule task performs validation and should accumulate all the issues found in the Record. The associated rules have the following characteristics:
-There are numerous action rules and decision tables. ?The rule conditions only involve the
Record class and its attributes. -The rule conditions perform many different tests in various order. -The action part of the rules only adds messages to a list that is not involved in the conditions of the rules.
Which execution settings should the application developer choose for the validation rule task?

A. Algorithm: RetePlus Exit Criteria: None
B. Algorithm: RetePlus Exit Criteria: RuleInstance
C. Algorithm: Sequential Exit Criteria: None
D. Algorithm: Fastpath Exit Criteria: RuleInstance

問題 #2

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.

問題 #3

A business analyst requests that Decision Center users who belong to the: ?Manager group can create, update, view, and delete rule artifacts, but cannot update the status of rule artifacts. ?Validator group can view rule artifacts or change their status, but cannot create, update and delete them. How should the application developer set up the Decision Center permissions table to meet these requirements?

A. Option D
B. Option B
C. Option C
D. Option A

問題 #4

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

問題 #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. Hosted Transparent Decision Service (HTDS)
B. Monitored Transparent Decision Service (MTDS)
C. Hosted Transparent Decision Service with the InterceptorEnabled parameter set to false
D. Remote EJB Rule Session
