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

1. When defining case specialization in the case designer, what underlying application rules are used? (Choose One)

A) A Case type and a Property
B) A Supporting flow and a Case type
C) A Property and a Starter flow
D) A Property and a Supporting flow

2. 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) Expose all columns used by the application
C) Limit the number of database interactions by storing most data on a series of declare pages
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

3. A work type MyCo-FW-PurchaseApp-Work-Request has a PageList property .LineItems of class MyCo-FW-PurchaseApp-Data-Item.
Another work type, MyCo-FW-PurchaseApp-Work-Order has a PageList property .ItemsForVendor of class MyCo-FW-PurchaseApp-Data-Item.
An item has a calculation .TotalPrice = .Quantity * .UnitPrice.
The application is experiencing behavior where the TotalPrice is calculating correctly for Requests but not for Orders. Which of the following is the most likely explanation for this issue? (Choose One)

A) The expression is likely defined as a context-sensitive expression ("only when the top level page is of the applies to class")
B) The expression is likely defined as backward chaining
C) The expression is likely defined as forward chaining
D) The expression is likely defined as a context-free expression ("regardless of any page it is contained in")

4. There is an application for which many reports created in production must pull data from more than one class. Which of the following statements best represents proper planning for this situation? (Choose One)

A) Application developers should create "template" reports with the corresponding class joins defined. Managers will then be able to do a "SaveAs" to build reports from them
B) No special planning is required; managers should be able to create these reports
C) Application developers should ensure that there are association rules between these classes
D) No special planning is required; application developers must create these reports

5. Which of the following statements are most accurate when it comes to guardrail reports? (Choose Two)

A) Guardrail reports can report on custom guardrail warnings
B) They are the only source to see the rules that violate guardrails
C) Must be run only after locking the rulesets
D) They are accessed in designer studio
E) They are used to check which rules violate best practices, but do not identify which rules might cause performance issues
