When is it appropriate to use a spin-off? (Choose One)

• A. When you wish to make a long-running SOAP service call asynchronously
• B. When you wish to start another flow execution while continuing down the current process path
• C. When you wish to run calculations in a separate thread from the current process
• D. When you wish to call multiple connector rules concurrently

In a Credit card dispute application PRPC connects to an external service to receive the transactions made by the account holder. When the CSR (Customer Service Representative) is working on the dispute they should see only the last twenty transactions made by the account holder. If the transaction that the account holder wants to dispute does not appear in the list then the CSR should perform a search by entering the date of transaction or the transaction amount or the merchant name. The transaction list should display the 20 transactions that satisfies the criteria. In any circumstance the CSR should not see more than 20 transactions in the screen and cannot paginate through results. The external service returns transactions ordered by date of transaction with the recent ones appearing first.
Given the above requirements, which of these approaches is most appropriate and would satisfy both these requirements? (Choose One)

• A. Build a thread level declare page that uses an activity to invoke the connector activity and then copy only the first 20 pages to the pagelist property defined in the declare page; this property is used as a source for the repeating grid. A when rule would be used to control when the results are fresh based on the values of the search parameters (transaction date, amount and merchant name)
• B. Execute the activity that makes a connector call to get the list of transactions from an external service before the flow action is rendered. Write a data transform to copy the connector result to a declare page. Create a repeating grid layout using the declare page as its source. Display the first 20 results of the declare page by using the pagination setting First X results
• C. Execute the activity that makes a connector call to get the list of transactions from an external service before the flow action is rendered so that all transactions are available on the clipboard. When a search parameter (transaction date, amount and merchant name) is specified, use a data transform to copy the appropriate subset of the transaction to a new page
• D. Build a thread level declare page which uses an activity as its source. The activity will invoke the connector activity and then copy only the first 20 pages to the declare page. Display the first 20 results of the declare page by using the pagination setting "First X" results

Using a PRPC-based application with the default lock timeout, you have requested a lock on a work item. PRPC responded by displaying a message indicating that you already hold a lock on that work item.
Which of the following describes the most likely reason? (Choose One)

• A. A developer has customized the standard "DetermineLockString" activity and probably introduced a bug
• B. System Pulse has not run yet to clear the lock string from the cache
• C. You have not properly logged out of the system after working on that work item couple of days ago
• D. You probably have a second PRPC Thread running

Consider the following situation:
A PRPC application is running within a 1.2 GB JVM (Java Virtual Machine). There is approximatively 400 MB of free memory and garbage collector reclaims in average 32 MB of memory in the course of an hour.
The application is generating approximately 30 database alerts per minute. The database CPU runs at an average of 76% peaking periodically at 97%. The alert log file does not report any byte warning with a 10 MB threshold defined.
The Rules Assembly count is 0 when a typical interaction executes in average 74.6 rules. The application CPU peaks periodically at 20% but otherwise runs in average around 12%.
Users are complaining about poor performance. Their interactions take in average 4.15 seconds.
Which of the following approaches is most appropriate to resolve this issue? (Choose One)

• A. Limit the number of database interactions by storing most data on a series of declare pages
• B. Avoid retrieving the BLOB column during database interactions
• C. Reconsider the database table indexes by reviewing query plans
• D. Review the application profile log to determine which activities are taking the most time
• E. Reduce the number of loop iterations executing on the large sets of data

PRPC's branching ability is most appropriate to use when __________. (Choose One)

• A. several development teams simultaneously work on the same enhancement in a RuleSet and it is not known ahead when the enhancement will go into production
• B. the single and only development team work on an enhancement in a RuleSet and it is not known ahead when the enhancement will go into production
• C. several development teams work on different enhancements in a RuleSet simultaneously that will go into production at the same time
• D. several development teams work on different enhancements in the same RuleSet simultaneously and it is not known ahead which enhancements will go into production first
