As a Lead System Architect, the primary objective is to adhere to the low-code application development methodology and support citizen developers. Relevant records are a feature in App Studio that can help facilitate this process. Which two of the following options outline the benefits of relevant records? (Choose Two)

• A. Relevant records regulate design-time prompting and filtering across various areas of App Studio, which reduces the time spent searching through unrelated records in cases.
• B. Users can promote instances from a built-on application for reuse in another application for effective data or case instance management.
• C. Users can achieve efficient resource management by promoting a rule from a built-on application, which enables its reuse in another class.
• D. Relevant records control the run-time availability of rules, which consequently decreases the time consumed during the rule performance.

As a Lead System Architect tasked with enhancing a hotel room booking application, your objective is to streamline the booking process by identifying high-value customers. To accomplish this, you have decided to segment customers based on the total revenue generated from their bookings, considering that customers can have multiple bookings. The revenue is calculated by summing the amounts of all bookings made by each customer. Customers will be categorized as follows: Silver: Total booking amount is less than $500. Gold:
Total booking amount ranges from $500 to $2000. Platinum: Total booking amount exceeds $2000. You want to use SQL functions for efficient customer categorization. Which SQL function code correctly determines the customer categories?

• A. IF {1} < 500 THEN 'Silver' ELSE IF {1} >= 2000 THEN 'Platinum' ELSE 'Gold' END
• B. IF {1} < 500 THEN 'Silver' ELSE IF {1} BETWEEN 500 AND 2000 THEN 'Gold' ELSE 'Platinum' END
• C. CASE WHEN {1} < 500 THEN 'Silver' WHEN {1} BETWEEN 500 AND 2000 THEN 'Gold' ELSE
  'Platinum' END
• D. SELECT CASE WHEN {1} < 500 THEN 'Silver' WHEN {1} BETWEEN 500 AND 2000 THEN
  'Gold' ELSE 'Platinum' END

Lead System Architects must enforce unit testing of code while developing Pega applications. Which of the following is considered the most important benefit of unit testing in Pega Platform?

• A. Unit testing helps to identify which unit test rules are best fit for the application and also helps to ensure the quality of the code.
• B. Unit testing helps identify functionality and code issues early in the development process and also helps ensure the quality of the code.
• C. Unit testing helps to identify performance issues early in the development process and also helps to ensure the quality of the code.
• D. Unit testing helps to identify memory allocation issues early in the development process and also helps to ensure the quality of the code.

As a Lead System Architect, you are developing a solution for enrolling students into culinary arts training sessions that includes two distinct specializations: Baking and Confectionery. Unique rules and business logic govern each specialization. Which of the following specialization techniques is considered most appropriate in this Pega implementation?

• A. Build separate classes for Culinary, Baking, and Confectionery, and position all three classes at the same hierarchical level, with common rules in a work pool class and specialized rules in their respective classes. This approach to class specialization helps define the scope and applicability of rules.
• B. Include all Culinary rules in the Culinary class, and then organize separate rulesets for Baking and Confectionery to differentiate the rules specific to each culinary specialization.
• C. Create a Culinary application that includes all general rules, followed by the creation of Baking and Confectionery as top-level applications that are built on the foundational Culinary application.
  Specializing at the application level makes managing their releases more manageable.
• D. Create distinct subclasses for both Baking and Confectionery under the primary Culinary class. Place common and specialized rules within the Culinary class in their respective subclasses. Using class specialization enables you to define rule scope and applicability.

Hospital XYZ wants to analyze patient data and identify those at high risk of readmission. The hospital has patient data stored in an Electronic Health Record (EHR) system, and a separate system for hospital admission records. Which two of the following are key advantages of using a Data Flow over a Queue Processor for analyzing patient data in this scenario? (Choose Two)

• A. Data Flow can directly access data from multiple systems.
• B. Data Flow can handle larger volumes of data.
• C. Data Flow can prioritize tasks based on urgency.
• D. Data Flow can process data in real-time.
