Pegasystems PEGACLSA_62V2 Exam : Certified Lead System Architect (CLSA) 6.2V2

A Connector rule is configured in PRPC to run asynchronously.
Which of the following statements is the most accurate with regard to its configuration or execution? (Choose One)

• A. When using the queue functionality you must also build the queue to be used by PRPC
• B. When using the queue functionality the connector's response is not available to the calling activity
• C. The "Page-Merge-Into" method performs better than the "Connect-Wait" method when needed to get the connector response
• D. Using the "Run in Parallel" option requires the users to hold a specific privilege

Consider the following situation:
A PRPC application is running within a 1.2 GB JVM (Java Virtual Machine). There is approximatively 400 MB of free memory and garbage collector reclaims in average 32 MB of memory in the course of an hour.
The application is generating approximately 30 database alerts per minute. The database CPU runs at an average of 76% peaking periodically at 97%. The alert log file does not report any byte warning with a 10 MB threshold defined.
The Rules Assembly count is 0 when a typical interaction executes in average 74.6 rules. The application CPU peaks periodically at 20% but otherwise runs in average around 12%.
Users are complaining about poor performance. Their interactions take in average 4.15 seconds.
Which of the following approaches is most appropriate to resolve this issue? (Choose One)

• A. Reduce the number of loop iterations executing on the large sets of data
• B. Avoid retrieving the BLOB column during database interactions
• C. Reconsider the database table indexes by reviewing query plans
• D. Limit the number of database interactions by storing most data on a series of declare pages
• E. Review the application profile log to determine which activities are taking the most time

Which of the following examples best demonstrate proper use of Declare Page rules? (Choose Two)

• A. To create a "Most Recently Used" (MRU) caching mechanism for external database queries
• B. To cache (at a node level) a small list of reference data that is expensive to retrieve
• C. To cache (at a node level) an extremely large list of reference data that is infrequently referenced
• D. To periodically poll external data for changes that will then trigger the recalculation of declarative expressions
• E. To retrieve data, when necessary, from an external service that is related to the current work object (such as accident reports for a driver)

Review the following requirement:
A claims application has as part of its process a step that sends a letter to an individual. After the letter is sent, the claims adjuster cannot do anything to the claim for 28 days. After those 28 days, the next step is for the claims adjuster to review the case details and make a processing decision. During those 28 days, the individual who received the letter may call up the front office and provide new information about the claim at which point the 28-day hold is lifted and the work is routed to the adjuster for the decision. The business says in most cases this call does not occur and the 28 days lapses.
Given the information provided, which design is most appropriate? (Choose One)

• A. After the letter is sent, route the work to a "pending" workbasket and place an SLA on it for 28 days. After the 28 days resume/move the flow to the decision step. At the same time spinoff an assignment to the front office to update work if a call comes in. After processing the update resume/move the flow to the decision step
• B. After the letter is sent, route the work to the front office to allow for the updating of the item if and when the call is made. Place a 28-day SLA on the work. If the SLA fires resume/move the flow to the decision step
• C. After the letter is sent, route the work to a "pending" workbasket and place an SLA on it for 28 days. After the 28 days resume/move the flow to the decision step. After processing theupdate resume/move the flow to the decision step. Create a search screen for the front office to find and update work if a call comes in
• D. After the letter is sent, use a split join to route the work to both the front office and adjuster. Place a 28-day SLA on the front office assignment to resume the flow if the 28 days lapses with no call

Which of the following usage patterns would likely benefit from a short passivation timeout? (Choose One)

• A. Any applications with over 1000 concurrent users
• B. An application where most users use the system for long periods of time with infrequent interactions
• C. An application where most users use the system for short periods of time with frequent interactions
• D. It is not recommended to use short passivation timeouts
