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

1. Which of the following statements is most accurate regarding connector error handling? (Choose One)

A) Connection errors, such as unable to resolve host, are best handled by the ConnectionProblem flow
B) All connector errors are handled by the ConnectionProblem flow
C) Connection errors, such as unable to resolve host, are best handled by using the step status of the calling activity
D) All connector errors must be handled using Java try/catch blocks

2. In what two ways are Declare OnChange and Declare Trigger similar? (Choose Two)

A) Both rule types execute directly in the browser
B) Both rule types provide out of the box configuration options to track changes in property values
C) Both rule types can execute activities
D) Neither rule type can be directly executed from another rule type
E) Both rule types can start a policy override

3. In a PurchaseOrder application, the ReviewOrderInformation screen displays the purchase order to the user for them to verify the entries before submitting for processing. In this screen the button label must display Confirm instead of Submit. Which of the following is the best option to handle this requirement? (Choose One)

A) Modify the label of the button in the Action section used in the perform harness
B) Change the label of the button in the flow action rule
C) Disable the buttons in flow action and add a custom pxButton in the section rule
D) Add a pxButton control in the flow action rule

4. 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) Review the application profile log to determine which activities are taking the most time
C) Expose all columns used by the application
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

5. Review the following requirement:
A PRPC-based stock trading application allows a pool of traders to initiate stocks sale on behalf of customers. However, such an operation should only be allowed during the Stock Market Trading Sessions.
The requirement for the application is to detect any operations occurring outside of the Trading Sessions hours, to suspend it and alert a group of auditors to review it and decide whether to allow it to go through during the next session or to simply reject it.
Which of the following approaches is the most appropriate for this requirement? (Choose One)

A) Build a when rule to identify a trade being initiated outside trading sessions, also build a Declare OnChange rule to track such a trade and suspend it, as well as a flow to review the work item and render a verdict on it
B) Build a Case Match rule with condition(s) to identify outside trading sessions trades. In a case match calling activity, loop through the retrieved cases and route them to a "Pending" workbasket. Then call a flow rule with an assignment to an auditor to review the case and make the appropriate decision
C) Setup the Auditors to be able to subscribe to business events. Configure a business event definition to monitor outside trading sessions trades. And when the event occurs, have the business event defintion notify the subscribers and call a review flow. Have the Auditors subscribe to the event definition
D) Tag any trade work item which pyCreateDateTime is not within the session hours and route the work item into the "Pending" workbasket. Send out a RSS feed to the auditors indicating the work item ID so they can create an ad-hoc work on that work item to review it, allow it or reject it
