    res-write-xom-db
  4. res-jar 
    res-write-file 
    res-write-xom-file
Correct answer: D



Question 2

An application developer previously deployed a rule project to the Test Decision Server environment. The rule project contained a deployment configuration (named Insurance) and a decision operation (named determineEligibility). After deployment and removal of some versions from the Test Decision Server, the currently deployed rulesets are as follows:
  
The application developer must now deploy an updated ruleset to the Test Decision Server with no impact to other testing. All other testing uses the following ruleset URL format:
Insurance/RAVmajor.RAVminor/determineEligibility/RSVmajor.RSVminor 
What deployment configuration settings should the application developer use to meet the requirements above?


  1. “Increment minor version numbers” versioning policy with base versions: 
    /Insurance/1.0 
    /determineEligibility/1.0
  2. “Define the version numbers” versioning policy with deployment time versions: 
    /Insurance/1.0 
    /determineEligibility/2.0
  3. “Define the version numbers” versioning policy with deployment time versions: 
    /Insurance/2.0 
    /determineEligibility/2.0
  4. “Use the base version numbers” versioning policy with base versions: 
    /Insurance/2.0 
    /determineEligibility/1.0
Correct answer: C



Question 3

While executing a RuleApp that has been deployed to the Rule Execution Server it becomes clear that the value of a ruleset output parameter has an unexpected result. It has been determined that the correct version of the RuleApp has been deployed to the Rule Execution Server and that monitoring has been turned on for the ruleset. 
How can the application developer determine which rules in the ruleset executed on the Rule Execution Server? 
From the Rule Execution Server console:


  1. open the Decision Warehouse View and review the related decision trace for the ruleset.
  2. open the ruleset view and review events which were logged on the Execution Unit (XU) used to execute the ruleset.
  3. open the Diagnostics View and Run Diagnostics on the RuleApp to review a list of rules which have executed for the ruleset.
  4. open the RuleApp view, and download the RuleApp archive trace to review the list of rules which have executed for the ruleset.
Correct answer: C



Question 4

An application developer is working on a rule project called “Pricing” which has monthly releases and is managed in Decision Center. There is a main branch, called “main”. In February the rules are deployed and the “February Release” deployment baseline is created. After creating several new rules for the March release in the “main” branch, a defect is identified in the “February Release” rules. 
What steps can the application developer take to fix the February rules, deploy the fixed rules and ensure the fixed rules are utilized in future releases?


  1. 1. From Decision Center, create a new sub-branch of “main” called “February Fix”. 
    2. Fix the rules in the “February Fix” branch in Decision Center. 
    3. Deploy the rules from “February Fix” and create a new deployment baseline. 
    4. Merge the “February Fix” branch into “main”.
  2. 1. Open the “February Release” deployment baseline in Decision Center. 
    2. Fix the rules in the “February Release” deployment baseline in Decision Center. 
    3. Deploy the rules from “February Release” and create a new deployment baseline called “February Fix”. 
    4. Merge the “February Release” branch into “main”.
  3. 1. From Decision Center, create a clone of the “February Release” deployment baseline and call it “February Fix”. 
    2. Fix the rules in the “February Fix” branch in Decision Center. 
    3. Deploy the rules from “February Fix” and create a new deployment baseline. 
    4. Merge the “February Fix” branch into “main”.
  4. 1. Create a new rule project in Rule Designer called “February Release”. 
    2. Synchronize the Rule Designer “February Release” project with the “February Release” baseline in Decision Center. 
    3. Fix the rules in the “February Release” project in Rule Designer. 
    4. Synchronize the Rule Designer “February Release” project with the “February Release” baseline in Decision Center and choose “Copy Current Change from Left to Right” in the Team Synchronizing Perspective. 
    5. Deploy the rules from “February Release” and create a new deployment baseline called “February Fix”.
Correct answer: B



Question 5

An application developer has deployed version 1.0 of a Java XOM and a decision service to a Rule Execution Server. The decision service is being tested by the business analyst through an internal application. Due to a change in requirements, the application developer updates the implementation of a XOM method and deploys version 2.0 of the Java XOM. The business analyst has asked for the ability to test with either version 1.0 or version 2.0 of the XOM without requiring any redeployment of the XOM. 
How can the application developer support the business analyst’s request?


  1. Within the Java XOM, set the ruleset.bom.enabled property to either enable or disable the Java XOM.
  2. Within the decision service, set the ruleset.managedxom.uris property to the required Java XOM version.
  3. Within the Ruleset of the decision service, set the ruleset.bom.enabled property to the required Java XOM version.
  4. Within the Ruleset of the decision service, set the ruleset.managedxom.uris property to the required Java XOM version.
Correct answer: C



Question 6

A rule task includes rules that test on existence or collection items directly in working memory, and also makes use of dynamic priorities. 
Which algorithm should the application developer set for this task?


  1. Fastpath
  2. RetePlus
  3. Sequential
  4. The default algorithm
Correct answer: B



Question 7

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?


  1. Add an additional node and create a cluster.
  2. Increase the memory available on the single node.
  3. Increase the JDBC connection pool size of the database from 15 to 25.
  4. Move the Decision Center database to the same physical host as the application server to reduce latency.
Correct answer: D



Question 8

Which one of the following describes a difference between the decision engine and the classic rule engine? 
Rules passed to the:


  1. classic rule engine are already compiled as code.
  2. classic rule engine can only use the BAL rule language.
  3. decision engine are already compiled as code.
  4. decision engine are not able to leverage working memory and agenda.
Correct answer: C



Question 9

After a long period of inactivity, an execution request of the only ruleset deployed to Rule Execution Server is delayed. 
Which change should the application developer make to avoid this problem?


  1. Increase the engine pool size.
  2. Increase the memory allocated to the server.
  3. Activate asynchronous ruleset parsing.
  4. Set the ruleset maxIdleTime property.
Correct answer: C



Question 10

An application developer is implementing the event logic of an online order handling application. The business requires that the order processing can only start after a two hour customer cancellation time period. 
How can the application developer implement this postponed processing of the Order Received event?


  1. Add a two hours delay statement to the when part of the business rule like this: 
    when an Order Received occurs 
    sleep(2*60*60/100)
  2. Add a time frame before the when part of business rule to postpone event processing for two hours like this: 
    after 2 hours 
    when an Order Received has occurred
  3. Implement the when part of business rule to postpone event processing for two hours like this: 
    when an Order Received has occurred 2 hours ago
  4. Implement a timer callback function Order Handling Timer and call it from the rule like this: 
    when an Order Received occurs, called ‘the order’ 
    call Order Handling Timer with order ‘the order’ and wait time 2 hours
Correct answer: C
