Demo Questions

Question 1

An application developer needs to check the eligibility rules pertaining to the state of New Jersey (NJ) in the Business Console. 
Assuming that the application developer has configured the ability to execute only the NJ rules, how can the application developer run tests that test only the NJ rules?


  1. Create a KPI file with data only pertaining to NJ.
  2. Run the excel scenario file from inside the NJ folder of the rule repository.
  3. Select the “NJ rules only” extractor on the Step 2 of Test Suite creation wizard.
  4. Select “check NJ rules only” from the operation drop down on the inside if the Test tab bar before running the test suite.
Correct answer: C



Question 2

Consider a rule based pricing system that allows for different pricing strategies to be used based on different types of corporate policies:
  • Lowest possible nationally available price on all products for government customers 
  • Price based on contract at highest hierarchical relationship 
  • Lowest price for a particular category of products 
Customers have types such as government, preferred, or new. Hierarchy means that a customer can have a contract with a vendor at levels such as global, regional or direct. Categories are properties of the product being priced such as safety, health, or clothing of which products may have more than one. The rules are organized into packages for each of the categories mentioned in this paragraph but are executed in different sequences based on the strategy that applies to the customer’s order. The vendor has about 1000 customers and 3000 products. 
Consider a problem where a government customer does not receive the lowest national price for a product and an application developer is tasked with figuring out why they are not receiving the correct price. 
Which set of actions leverages the list of capabilities for understanding the rule logic when the system is still in the pre-production testing phase?


  1. 1. Use the Business Console to examine decision trace. 
    2. Isolate the rules related to government pricing and execute them without a rule flow. 
    3. Add the rules back into the full rule flow and test that the rules work in the context of the other logic in the flow. 
    4. Use verbose Rule Execution Server logging and inspect the log files.
  2. 1. Isolate the rules related to government pricing and execute them without a rule flow. 
    2. Add the rules back into the full rule flow and test that the rules work in the context of the other logic in the flow. 
    3. Use the Decision Warehouse to examine decision trace. 
    4. Use verbose Rule Execution Server logging and inspect the log files.
  3. 1. Remove all of the conditions from the rules that are not firing and call the rules and test that the rules work in the context of the other logic without any conditions in the flow. 
    2. Add the conditions back into the rules and test that the rules work in the context of the other logic in the flow. 
    3. Use the Decision Warehouse to examine decision trace. 
    4. Use verbose Rule Execution Server logging and inspect the log files.
  4. 1. Remove all of the conditions from the rules that are not firing and call the rules and test that the rules work in the context of the other logic without any conditions in the flow. 
    2. Isolate the rules related to government pricing and execute them without a rule flow. 
    3. Use the Decision Warehouse to examine decision trace. 
    4. Run the Rule Designer Debugger and inspect working memory. 
    5. Use verbose Rule Execution Server logging and inspect the log files.
Correct answer: D



Question 3

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:
  
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)?


  1. Utilize the IlrVocabularyMergeConflictHandler API to merge the customer objects into one so there is no conflict at runtime.
  2. Redefine the rule project’s ruleset parameter to be a single customer verbalized as ‘my customer’ and remove the definition part from the rule.
  3. Include the complete domain for the loan type requested in the condition of the rule as follows: the loan type requested of ‘my customer’ is one of { “A”, “B”, “C”. “D”}.
  4. Split the rule into two rules with one rule using condition if the loan type requested of ‘my customer’ is “A” and the 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”.
Correct answer: D



Question 4

An application developer is preparing an Excel scenario file template to enable the business users to test business rules. Some attributes in the BOM are purely technical and do not need to be filled in by the business users. 
How can the application developer exclude these technical attributes from being generated for the scenario file?


  1. Specify in the BOM that these attributes are ignored for DVS purposes.
  2. Tag these attributes with the IGNORE descriptor in the Rule Execution Server.
  3. Delete the rows that represent these attributes from the Excel scenario file template.
  4. Delete the columns that represent these attributes from the Excel scenario file template.
Correct answer: A



Question 5

An application developer has created a batch process that leverages an embedded Java SE rule engine to validate some data, calculate some values, and report some recommendations for business users. 
Some new calculation changes introduced by the application developer worked perfectly in the development, quality assurance, and staging environments but do not work when run in the production environment. Some of the calculations produce incorrect values. The calculations depend on some external data sources for information which the business users maintain. 
The business users know which version of the batch process they are running but the application version and the RuleApp versions have no correlation because of poor application governance. The application developer suspects that the data sources maintained by the business are wrong. The business believes that the new calculations are executing wrong. 
In addition to poor deployment governance, the application does not log information about the rules or external data being used. Furthermore, the use of the embedded rule engine does not leverage hot deployment of rules so the application developer is not sure how to determine if the new calculations are being used by the business users. 
How can the application developer diagnose the situation?


  1. Compare the data from the data sources in production to the data in the data sources in the non-production environments. Diagnosis of the rules are not required.
  2. Unpack the application JAR file and compare the RuleApp rules embedded in the JAR file to the last RuleApp on the developer’s file system.
  3. Run the batch program with remote debug flags set and use the application developer’s Rule Designer to debug the Java application and rules remotely.
  4. Ask the business users which version of the application was being used and use that information to determine which rules are embedded in the application.
Correct answer: C



Question 6

A business user would like to test and simulate a classic rule project remotely from Decision Center. 
What does the application developer need to do to make the business rules accessible for remote testing?


  1. 1. Export the business rules project from Rule Designer to a RuleApp. 
    2. Repackage the RuleApp within the SSP. 
    3. Deploy the RuleApp on Decision Center.
  2. 1. Install a remote business rules proxy on Decision Center. 
    2. Configure the business rules proxy to use SSP. 
    3. Establish a secure connection between Decision Center and Rule Execution Server.
  3. 1. Configure Decision Center for remote access to Rule Designer. 
    2. Deploy the rules project to the remote Rule Execution Server. 
    3. Install SSP on Decision Center. 
    4. Establish a secure connection between Decision Center and Rule Execution Server.
  4. 1. Repackage the XOM within the SSP in Rule Designer. 
    2. Deploy the repackaged SSP to the remote Rule Execution Server. 
    3. Publish the rules project to Decision Center. 
    4. Configure Decision Center so that it can access the Rule Execution Server that references the SSP and stores the XOMs.
Correct answer: C



Question 7

A decision service has been developed and synchronized to Decision Center for the first time with ‘Decision Governance Framework’ enabled. Rule authors are now ready to make updates to the rules within Decision Center for the next release, Release 2.0. 
What steps does an application developer need to take to enable rule authoring within Decision Center?


  1. Rename the release ‘InitialRelease’ to ‘Release 2.0’. 
    Create a new branch for authoring.
  2. Rename the release ‘InitialRelease’ to ‘Release 2.0’. 
    Create a change activity for authoring.
  3. Create a new ‘Release 2.0’ release based on ‘InitialRelease’. 
    Create a new branch for authoring.
  4. Create a new ‘Release 2.0’ release based on ‘InitialRelease’. 
    Create a change activity for authoring.
Correct answer: C



Question 8

Security has been enabled in Decision Center for the main branch of a given decision service. A specific user belongs to a group that has access to that main branch. This user must be able to access and rename an action rule in a sub-branch of the main branch of the decision service. 
What does the application developer need to configure in the Enterprise Console to meet these requirements?


  1. Add the user to the rtsUser group.
  2. Give the user the following permission: Update | Yes | Action Rule | Name.
  3. Set up the sub-branch to inherit its security configuration from the main branch.
  4. Set up the sub-branch to inherit its security configuration from the main branch and give the user the following permission: Update | Yes | Action Rule | *.
Correct answer: A



Question 9

Within a rule application project, a business-user-centric approach has been selected and has established Decision Center as the master source. An application developer performs a synchronization of a rule project within Rule Designer and is notified of a conflict in a rule file. 
In the context of the established master source, what action must be application developer take to resolve the conflict?


  1. Update
  2. Publish
  3. Override and Update
  4. Override and Publish
Correct answer: A



Question 10

An application developer needs to automate the build and deployment process of their RuleApp. Their Rule Execution Server is configured in a Java EE environment using database persistence mode, their rule project has a Java XOM and they require automation to include hot deployment of the RuleApp. 
Which sequenced Ant tasks should the application developer use to create an automated RuleApp build and deployment script?


  1. res-deploy 
    res-deploy-xom
  2. res-jar 
    res-deploy 
    res-deploy-xom
  3. res-jar 
    res-write-db 
    res-write-xom-db
  4. res-jar 
    res-write-file 
    res-write-xom-file
Correct answer: D
