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

1. A framework rule has been overridden with a copy in the implementation layer. Both rules are in locked RuleSet versions. An architect wishes to restore the framework functionality. Which of the following will NOT accomplish this? (Choose Two)

A) Copy the framework rule to a higher framework RuleSet version in the framework class
B) Copy the framework rule to a higher implementation RuleSet version in the implementation class
C) Mark availability of the implementation layer rule as "No/Draft"
D) Unlock the implementation RuleSet version, and delete the implementation layer rule
E) Create a withdrawn copy of the implementation rule in a higher implementation RuleSet version

2. Your application uses a custom Rule Type created to handle a specific business requirement. Which of the following is the most recommended option to permanently enable logging level on all rules belonging to that rule type? (Choose One)

A) Use SMA to set the logging level
B) Create a new appender in prlogging.xml
C) Set the logging level using the Logging level gadget in Designer Studio
D) Create a new category in prlogging.xml

3. Which of the following does NOT describe a typical upgrade from one PRPC version to another? (Choose One)

A) Install the PRPC Rulebase on a different instance and migrate the application rules, data and work to the new system
B) Install only those items in the PRPC Rulebase that have been updated on an existing system
C) Install an entire new version of the PRPC Rulebase on an existing system, including those items that have not changed
D) Install the PRPC Rulebase on a different instance and migrate only the application rules and data to the new system. The work remains on the original instance

4. A rule is shown in the Final Conflicts report after doing an upgrade. Which of the following describe what could be done to resolve the conflict? (Choose Two)

A) The rule could be copied into a more specific class
B) The rule could be marked Final
C) The rule could be deleted or Withdrawn so that the standard version of the rule is executed
D) The corresponding RuleSet could be locked
E) Do a SaveAs on the conflicting rule to a new name and update references to this new rule
F) The rule could be copied into the production RuleSet

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) Review the application profile log to determine which activities are taking the most time
B) Expose all columns used by the application
C) Review the database table indexes and utilize query plan to consider changes
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
