Question 1

Given the following classes and properties:
MyCo-Data-Shape-.Area .Color
MyCo-Data-Shape-Rectangle .Length .Width
MyCo-Data-Shape-Circle .Radius
A page list property is defined at the class group MyCo-FW-ShapeApp-Work. The property name is .Shapes and it is defined as being a Page List of class MyCo-Data-Shape-
Which of the following statements are NOT correct? (Choose Two)

A. At design time an architect can create a rule in MyCo-Data-Shape-Circle regardless of if the rule exists in MyCo-Data-Shape- B. At runtime .Shapes(1) could be of class MyCo-Data-Shape-Rectangle while .Shapes(2) is of class MyCo-Data-Shape-Circle C. At design time PRPC will provide a warning as it is not a good practice to define a page list with an abstract class D. A rule defined in MyCo-Data-Shape-Rectangle can modify the .Color property E. At runtime pages of .Shapes can be of either MyCo-Data-Shape-Rectangle or MyCo-Data-Shape-Circle but all pages must be the same.

Correct Answer: C,E

Question 2

Which of the following examples best demonstrate proper use of Declare Page rules? (Choose Two)

A. To cache (at a node level) a small list of reference data that is expensive to retrieve B. To create a "Most Recently Used" (MRU) caching mechanism for external database queries C. To periodically poll external data for changes that will then trigger the recalculation of declarative expressions D. To retrieve data, when necessary, from an external service that is related to the current work object (such as accident reports for a driver) E. To cache (at a node level) an extremely large list of reference data that is infrequently referenced

Correct Answer: A,D

Question 3

In which situations would you typically use rule check-in approval? (Choose Two)

A. To control changes to rules delegated directly in production B. To control who can update rules C. To review rule changes made by system architects D. When business logic requires a manager to review a work item E. To track interface changes for connectors

Correct Answer: A,C

Question 4

Which of the following statements is TRUE with respect to PRPC integration with JMS? (Choose One)

A. PRPC only supports integration with JMS on EAR deployments B. PRPC supports MDB JMS listeners on WAR deployments and blocking JMS listeners on EAR deployments C. PRPC supports MDB JMS listeners on EAR deployments and blocking JMS listeners on WAR deployments D. PRPC only supports integration with JMS on WAR deployments

Correct Answer: C

Question 5

Consider the following situation:
A PRPC application is running within a 1.2 GB JVM (Java Virtual Machine). There is approximately 350 MB of free memory and garbage collector reclaims in average 32 MB of memory in the course of an hour.
The Rules Assembly count is 0 when a typical interaction executes in average 72.6 rules. The application CPU peaks periodically at 22% but otherwise runs in average around 12%.
The application is generating approximatively 30 database alerts per minute. The database CPU runs at an average of 75% peaking periodically at 96%. The alert log file does not report any byte warning with a 10 MB threshold defined.
Users are complaining about poor performance. Their interactions take in average 4.5 seconds.
Which of the following approaches is most appropriate to resolve this issue? (Choose One)

A. Expose all columns used by the application B. Review the database table indexes and utilize query plan to consider changes C. Review the application profile log to determine which activities are taking the most time D. Reduce the number of loop iterations executing on the large sets of data E. Limit the number of database interactions by storing most data on a series of declare pages

Correct Answer: B

Question 6

Review the following requirement:
A PRPC-based stock trading application allows a pool of traders to initiate stocks sale on behalf of customers. However, such an operation should only be allowed during the Stock Market Trading Sessions. The requirement for the application is to detect any operations occurring outside of the Trading Sessions hours, to suspend it and alert a group of auditors to review it and decide whether to allow it to go through during the next session or to simply reject it.
Which of the following approaches is the most appropriate for this requirement? (Choose One)

A. Define a when condition rule to identify a trade being initiated outside trading sessions, a Declare OnChange rule to track such trade and suspend it, as well as a flow to review the work item and render a verdict on it B. Setup the Auditors to be able to subscribe to business events. Configure a business event definition to monitor outside trading sessions trades. When the event occurs, have the business event defintion notify the subscribers and call a review flow. Have the Auditors subscribe to the event definition C. Build a Case Match rule with condition(s) to identify outside trading sessions trades. In a case match calling activity, loop through the retrieved cases and route them to a "Pending" workbasket. Then call a flow rule with an assignment to an auditor to review the case and make the appropriate decision D. Tag any trade work item which pyCreateDateTime doesn't fall within the session hours and route the work item into the "Pending" workbasket. Send out a RSS feed to the auditors indicating the work item ID so they can create an ad-hoc work on that work item to review it, allow it or reject it

Correct Answer: A

Question 7

Which of the following statements are most accurate about case-based reasoning? (Choose Two)

A. The application rule that executes the case match rule is responsible for handling situations when no results are returned by the Case Match rule B. The "Case Matching Type" of the Case Match rule determines the activity method to use to call the Case Match rule C. Case-based reasoning relies on the forward chaining principle of a Rule-Declare-CaseMatch rule D. The conditions listed under the "Skip Pages that match any of these conditions" on the "Retrieval" tab of a Case Match rule are evaluated prior to the "Match conditions" defined on the "Evaluation" tab during a case-based reasoning execution E. When implementing a case-based reasoning functionality, you must define an activity to directly call the Case Match rule

Correct Answer: A,D

Question 8

Which of the following tools are useful in identifying the slowest running DB query? (Choose Two)

A. Run Explain Plan B. Activity Profiler C. Tracer tool D. Alert Log files E. Performance Analyzer

Correct Answer: C,D

Question 9

In what two ways do Declare OnChange and Declare Trigger instances differ? (Choose Two)

A. Declare OnChange rules cannot execute a commit; Declare Trigger rules can B. Declare OnChange rules run in memory; Declare Trigger rules run directly on the database server C. Declare OnChange rules can start a policy override; Declare Trigger rules cannot D. Declare Trigger activities can be run in a child (background) requestor; Declare OnChange rules cannot E. Only Declare Trigger rules can execute activities

Correct Answer: C,D
