I decouple data representation, application behavior, and presentation

  1. Model View Controller

  2. Business Delegate

  3. Composite View

  4. Service Locator
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

MVC (Model-View-Controller) separates data representation (Model), application behavior (Controller), and presentation (View) into three distinct components. This separation allows independent development, testing, and maintenance of each aspect. The Model handles data, View handles display, Controller handles user input and coordination.

Which statement is true of Worklets but NOT of Mapplets?

  1. They are reusable by nature

  2. They encapsulate part of the functionality of a Workflow/Mapping

  3. They have their own Designer tool

  4. They can be nested
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Worklets can be nested within other worklets (hierarchical workflow organization), but Mapplets cannot be nested within other mapplets. Both are reusable, both encapsulate functionality, but only worklets support nesting. This is the key distinguishing feature.

How to mark an action as reusable?

  1. Action Settings

  2. Action properties

  3. Action Run Settings

  4. Action Call properties
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

In QTP, you mark an action as reusable through the Action Properties dialog (right-click the action → Action Properties). This is not done through Action Settings (which handles iteration), Action Run Settings (for action call parameters), or Action Call properties (which configures how an action is called, not its reusability). Option B correctly identifies the location.

  3. Declare Decision Tree

  4. Activity Steps
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

In the Pega Tracer, 'Event Types To Trace' includes Flow, Declare Constraint, and Declare Decision Tree. Activity Steps are not listed as a separate event type to trace - you trace Activities as a whole, not individual steps. This is why Activity Steps is the correct answer.

SmartBuild in PEGA follows a logical development sequence starting with Class Structure (defining data model), then Properties (individual attributes), User Interface (forms and screens for user interaction), and finally Activities (business logic and processing). This sequence ensures foundational elements are established before building dependent components.
