QUESTION NO: 1
Every day at 1 AM, all the ATM transactions at ABC Bank from the previous day are shared with the head office of the bank. All ATM machines perform this data sharing. ABC Bank uses this information to validate transactions and balance all the ledgers. If any discrepancy is identified, a dispute resolution flow initiates to investigate the root cause and resolve the dispute. ABC Bank has 1 million ATMs for which transactions need to be analyzed for discrepancies. Which one of the following is the optimal solution for gathering the transaction information from all the ATMs?

A. The ATM machines generate an Excel file of all the transactions and place it in a NAS directory. Pega workflow processes the files using an Advanced agent. B. The ATM machines generate an Excel file of all the transactions and place it in a NAS directory. Pega workflow processes the files using a Job Scheduler. C. The ATM machines generate an Excel file of all the transactions and place it in a NAS directory. Pega workflow processes the files using a Queue Processor. D. The ATM machines generate an Excel file of all the transactions and place it in a NAS directory. Pega workflow processes the files using a Data Set of type File, and feeds the files into a Data Flow.

QUESTION NO: 3
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. 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. 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. 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.

QUESTION NO: 6
You are a Pega developer working on an insurance application. The application needs to manage different types of insurance policies such as car insurance, home insurance, and life insurance. Each type of insurance policy has some common attributes (policy number, policyholder name, and premium amount), but also has some unique attributes (such as vehicle details for car insurance, property details for home insurance, and beneficiary details for life insurance). Which one of the following approaches to handling this scenario would be most appropriate in a Pega application?

A. Create a separate class for each type of insurance policy and then define the common attributes in the new class. B. Create a single class for all types of insurance policies and define all possible attributes. C. Create a base class for the insurance policy for the common attributes, and then create derived classes for each type of insurance policy with their unique attributes. D. Create a single class for all types of insurance policies and dynamically add or remove attributes as needed.
