質問 3：
Decision Center is currently deployed and running with the application server on a single node (physical host) and the database on a separate physical host within the same subnet. The rule authors using Decision Center are experiencing slow response times on various operations and are not able to isolate the cause. The following characteristics are present:
* More than 10 rule authors are using Decision Center simultaneously.
* Most rule authors are browsing the repository and locating rules by clicking into folders.
* Multiple rule authors are iteratively editing a rule and running a test suite to see the impact.
* Multiple rule authors are iteratively editing and saving very large decision tables.
What should the application developer tune to improve performance?
A. Increase the memory available on the single node.
B. Move the Decision Center database to the same physical host as the application server to reduce latency.
C. Increase the JDBC connection pool size of the database from 15 to 25.
D. Add an additional node and create a cluster.
正解：D

質問 4：
An application developer needs to shrink the number of events being held in memory to reduce the memory footprint of the solution after an out-of-memory error. After reducing the event time horizon for events, agents, and aggregates, there is a problem with the accuracy of the aggregates.
Which combination of artifact definition and property values show the problem?
A. Aggregate definition of:
define 'total number test events' as the number of test events during the last period of 24 hours In the solution_properties.xml:
<property name="eventAggregateMaxHorizon>PT36H
</property>
B. Aggregate definition of:
define 'total number test events1 as the number of test events during the last period of 2 days In the solution_properties.xml:
<property name="maxHorizon">PT12H</property>
正解：A

質問 5：
An application developer completed initial development on a classic rule project and now opens the Rule Analysis view in Rule Designer to analyze the rule project for consistency.
The rule project contains a package with the following rule named Set Package Loan Type:
definitions
set 'my customer1 to a customer in 'the customers' ; if
the loan type requested of 'my customer' is one of { "A" , "B" } then
set the loan type of 'the package' to "Type " + the loan type requested of 'my customer' ; When the rule analysis report returns, the results include the following identified problem:
Several executions of rule 'Set Package Loan Type' are conflicting.
For instance, when:
then the loan type of the package is set to "Type " + "A" in the first execution of the rule 'Set Package Loan Type' and to "Type " + "B" in the second execution of the rule 'Set Package Loan Type' How should the application developer resolve the self-conflicting rule without causing additional rule conflict(s)?
A. Redefine the rule project's ruleset parameter to be a single customer verbalized as my customer' and remove the definition part from the rule.
B. Utilize the HrvocabularyMergeConf lictHandler API to merge the customer objects into one so there is no conflict at runtime.
C. Split the rule into two rules with one rule using condition if the loan type requested of my customer1 is
"A" and action then set the loan type of 'the package" to "Type A", and follow the same pattern in the second rule using "B" and "Type B".
D. Include the complete domain for the loan type requested in the condition of the rule as follows: the loan type requested of 'my customer1 is one of { "A" , "B" , "C" , "D" }.
正解：C

質問 6：
Some entity attributes need to load their values from an outside datasource.
How can the application developer develop the required data provider?
A. Develop a data provider class, repackage it with the runtime EAR, and set the 'dataProvider' property of the solution to the full implementation class name.
B. Define a data provider in the model as well as how it enriches the entity, create the extension project, and develop the provider implementation class within the extension project.
C. Update the incoming event structure to bring in new data, define a data provider class to enrich the entities with the new values, and set the 'dataProvider' property of the solution to the full implementation class name.
D. Develop a data provider class at the XOM level and set the 'dataProvider' property of the solution to the full implementation class name.
正解：B

質問 7：
An application developer needs to configure a predictive scoring agent to be able to obtain a customer's probability of closing their account.
In addition to the following step, what other steps does the application developer need to complete to configure the agent where the order of defining the other steps does not matter?
