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) Limit the number of database interactions by storing most data on a series of declare pages
B) Expose all columns used by the application
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) Review the database table indexes and utilize query plan to consider changes

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

3. In a PRPC application the ViewPortfolioInformation section has three accordion layouts: Stock Details, Stock graphs and Trade/Payment history. What is the preferred design you will do to make the screen display latest details when they are accessed? (Choose One)

A) Write a timer script that periodically does a section refresh
B) Defer load on all accordion layouts, selecting them will render data everytime
C) Add Refresh When condition on each Accordion layouts that refreshes on a When rule which uses a timer to fire the event
D) Enable the Refresh When active feature on accordion layouts to get the recent transaction

4. In a PRPC application the Collect Information section has three tabs: Personal Details, Transaction History and Comments. When the user is working on the case they will open the transaction history only when it's required. What is the preferred design you will do to make the screen render faster? (Choose One)

A) Disable the transaction history tab and use a visible when condition that uses run on client to enable the transaction tab when required
B) Modify the layout to use accordion because transaction history need not be displayed unless its required
C) Enable Defer Load, so the page loads only with the contents in the active tab
D) Enable Refresh When active flag so it refreshes the list when accessed

5. You are building a PRPC-based application. Knowing that PRPC is deployed as a web archive (WAR deployment), which of the following service Rules would you least likely be able to implement? (Choose One)

A) HTTP Service
B) JMS MDB Listener
C) Email Listener
D) JMS Listener
