Pegasystems PEGACPLSA88V1 Exam With Confidence Using Practice Dumps

Identifying and resolving out-of-memory errors in a cluster node involves understanding the alerts that typically precede such conditions.

PEGA0004 – Quantity of data received by database query exceeds limit (Answer A):

Explanation: This alert indicates that a database query is returning more data than expected, which can lead to memory issues as the system tries to handle large data sets.

 Column Importance: The importance setting helps define which columns are displayed on smaller screens. "Primary" ensures the column is always visible, "Secondary" is shown if there is enough space, and "Other" is hidden on smaller screens.

 Restaurant Name as Primary: Setting the restaurant name to primary ensures it is always visible, as it is crucial information for making a reservation.

 Image Column as Other: Setting the image column to "Other" hides it on small screens, which is acceptable as images are non-essential compared to textual information.

 Location and Reservation as Secondary: These columns are set to secondary, ensuring they are visible on medium to large screens but can be hidden on smaller screens if space is limited.

 Reference: Pega guidelines recommend using the importance settings to manage the visibility of columns in responsive layouts, ensuring critical information is prioritized (Pega Platform 8.7 Documentation, User Interface - Column Settings).

 Service Request Processor for Asynchronous Processing:

Configuring a REST service to run asynchronously using a service request processor ensures that the service runs without making the external application wait. The system returns a unique identifier instantly and processes the request in the background.

 References:

Pega's best practices for REST services and asynchronous processing recommend using service request processors for handling long-running processes.

 Therefore, the correct answer is:

B. A REST service that runs asynchronously by using a service request processor.
