Pegasystems Certified Lead System Architect (CLSA) 6.2V2 Sample Questions:

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

2. Your application uses a custom Rule Type created to handle a specific business requirement. Which of the following are the recommended options to temporarily enable logging level on all rules belonging to that rule type? (Choose two)

A) Set the logging level using the logging level gadget in designer studio
B) Change the logging level using dynamic system settings
C) Create a new appender in prlogging.xml
D) Create a new category in prlogging.xml
E) Set the logging level using the SMA

3. An application, created by MyCo, has a number of rules implemented as decision tables that use "Title" as an input as seen in the sample rule below:
MyCo is finding a number of application defects caused by incorrect spellings in the title field. The valid titles are stored as field values. MyCo is requesting options to help prevent these types of errors. Which of the following approaches is most applicable? (Choose One)

A) Use the table edit of the .Title property to reference the field values, the decision table will then automatically validate that the value is valid
B) Recreate the logic in decision trees and use function aliases to limit the options via a drop down box
C) Create a custom validation rule in the Rule-Declare-DecisionTable class to validate that the .Title property always has a valid value
D) Create a custom rule form that uses harnesses and sections and can be configured however MyCo desires

4. Which of the following statements most accurately describes dependency management? (Choose One)

A) In order for 2 cases to depend on each other, they should have a direct parent-child relationship
B) The waiting case can move forward only when all cases it is waiting for are completed
C) The dependency configuration could be done through the case type rule form of the top-level case
D) A dependency can be configured to instantiate a case when another case has started

5. 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) 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
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 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
C) 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)
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
