Basic Pega Interview Questions

What do you mean by workplace or studio in the context of Pega?

A workstation is a designated area with particular equipment and amenities. You can facilitate teamwork by assigning tasks that correspond with individual skills and utilizing distinct workspaces for the development and administration of your application.

The Pega platform offers four role-based authoring workspaces, or “studios.”

  • App Studio
  • Dev Studio
  • Prediction Studio
  • Admin Studio

What role does the Service Page rule play in the development of a service?

When Pega apps are acting as service providers and delivering the service, a Service Package rule is produced. The service package rule has three key functionalities configured.

Processing Mode: Two varieties of processing modes exist.

  • State Full: We select state full processing mode in state-full mode when we wish to use a requestor’s clipboard data for other or subsequent requests.
  • Stateless: In this case, each request will be treated as unique.

Access Group: The incoming requestor running the access group uses this to determine the service rules.

Authentication: Incoming requests are authenticated using this.

When will we be establishing the connector rule in Pega?

When we needed to use the service that the other applications were providing, we defined the connection rule in Pega.

For example, if the protocol is SOAP, the REST CONNECT rule is used for restful services and the SOAP CONNECT rule is used for SOAP.

What is Pega’s service rule and when will it be created?

When a Pega application wants to offer a service (service provider), a service rule in Pega is defined. For example, if the protocol is SOAP, then the SOAP SERVICE rule needs to be defined; if the protocol is REST, then the REST SERVICE rule needs to be created.

What is SOAP and why is it used?

The protocol known as Simple Object Access Protocol, or SOAP, is used to transfer services between providers and requesters. This communicates using XML as the intermediary language. Since SOAP uses XML, it is more secure.  Because SOAP is platform- and language-neutral, it functions well on all operating systems. Because it uses XML for communication, SOAP has a low weight. The Web services industry’s governing organization, the W3C consortium, recommends SOAP. 

Describe REST and its goals.

A web service protocol that is resource-based is representational state transfer. This is most frequently utilized due to its low maintenance requirements, excellent scalability, simplicity, and small weight. Creating web application APIs is the most popular use case for this.

The consumer is exposed to the APIs in a standard, stateless, and secure manner through the REST protocol. The four techniques are listed below.

GET: This is how you utilize the service to obtain records or information.

PUT: This is how you utilize the service to update the records.

POST: By utilizing the service, this is how records are created and information is sent.

DELETE: Using the service, this is how records are deleted.

What are Pega classes like? 

The Pega Platform classifies rules based on how much they can be reused. Every assembly is a class. There are three different kinds of classes in each application.

Work Class: The Work class has procedures, data pieces, and user interfaces that specify how to handle a case or cases.

Integration Class: The rules governing the application’s interactions with other systems, such as the integration assets that link it to a third-party web server or a customer database, are contained in the Integration class.

Data Class: The rules that define the data objects used in the application—like the data types for customers and order items—are contained in the data class.

In Pega, what are you referring to as a work object?

A work object is the main data collection that a flow functions on and the main unit of work completion in an application. Employees utilize an application to create, amend, resolve, and finally close work objects. Each work object has a distinct ID (property pyID), a status (property pyStatusWork), and an urgency value.

What do you know about Pega’s DCO?

Directly Capture Objectives (DCO) is the Pega ExpressTM method for seamless end-to-end collaboration. DCO promotes excellent communication between business and IT and aligns stakeholders. DCO is an approach to work that creates an ongoing cycle of validation, iteration, and cooperation.

What is your knowledge of SLA about Pega?

A service-level agreement (SLA) sets a date for the completion of the work. Organizations regularly draft service-level agreements to guarantee prompt performance. These duties can take the form of written contracts or unofficial commitments to respond quickly. It’s a tool for setting and enforcing the anticipated reaction or resolution time for a given task or situation. SLAs assist in monitoring and controlling the efficiency and promptness of different application processes. Check out what the RPA course fee is in Chennai at SLA Jobs. 

What types of SLAs are there?

Service-level agreements (SLAs) come in three primary varieties: multilevel, internal, and customer.

  • An external customer and a service provider have a customer service-level agreement. Occasionally, it’s referred to as an external service contract.
  • An organization’s internal client, which could be a different department, site, or organization, is the subject of an internal SLA.
  • A multilayer SLA will break the contract down into different tiers tailored to a range of service users.

Advanced Pega Interview Questions

How do Edit Validate and Edit Input Rules differ from one another?

Edit Validate: To validate the value of the property, use the Java code’s edit validate rule. Use property-validate, Rule-Obj-Validate, or property rules to modify validate rules.

Modify Input Rules: To ensure that user-entered data is formatted correctly, utilize input rules. The edit input rule converts a date that a user provides in MM/DD/YYYY format to DD-MM-YYYY (the required format). For this shift, we have to write Java code once again.

What is the SOAP Protocol’s WSDL file and why is it important?

Web services description language, or WSDL for short, provides information about SOAP services.

It has parameters for input and output that are necessary for the service.

It outlines the functions that the service offers.

Additionally, it contains the endpoint URL for the service’s location. The SOAP protocol is essentially described using WSDL nomenclature.

What is the SOAP protocol’s endpoint URL and how important is it?

The address to which we submit our request to initiate the actions offered by the service is known as the endpoint URL.

What benefits may using data pages offer?

Data pages use the clipboard to store data that is pulled dynamically from the tables for use in the application.

Declarative in nature, data pages are created on the clipboard for user use when we refer to the data page system, which executes the source.

Why are declarative pages another name for data pages?

Because the system executes the source when a data page is referred to, it obtains data from the source and copies it to the clipboard for user use. This is why data pages are also known as declarative pages.

Describe the scopes on a data page.

Three varieties of scopes are listed below.

Thread: Only this thread’s data page is accessible. For example: job object

Requester: The data page is open for the requestor session.

Node: Every operator within the node has access to this.

Why Node-Level data pages require access to groups?

Multiple operators will be able to access the data page on node-level data pages. To use the relevant source, the operator’s rule-set hierarchy is necessary. Thus, to create the rule-set hierarchy for the operators, access groups are necessary.

The number of types that are Are there data pages available? And give a thorough explanation.

There are 3 types of data pages based on their usage; they are,

Read Only: The data is read using the data page.

Editable: Content on data pages can be read and edited as needed.

Savable: Requires reading, updating, and saving back to the source.

Know the difference between RPA and selenium. They are generally automation tools. But there are many differences. 

The Difference Between Data Page and Clipboard Pages

Standard pages that are saved on the clipboard are considered static, meaning they lack a refresh strategy, scope, and other features.

The data pages in the clipboard can be referenced in the user interface, have a defined scope, and are fetched dynamically from the source.

What differentiates backward chaining from forward chaining?

When a declared expression is evaluated each time an input value changes, this method is referred to as forward-chaining. Backward chaining occurs when a declared expression is evaluated upon reference to the target property.

What does Pega’s inheritance concept (rules, class) mean?

Pega’s concept of inheritance for classes and rules

Rules: inheritance that can allow for a localized override when necessary while also optimizing rule reuse. A rule created for one class (perhaps an abstract class) can be applied to other classes that inherit from it thanks to inheritance, also referred to as polymorphism.

Class: Class inheritance looks up the class hierarchy for rules from a concrete, lower class to determine which rules are available. There are two categories for class inheritance: pattern inheritance and directed inheritance.

What are the rules for StepStatusGood and StepStatusFail?

“StepStatusGood” indicates that a certain action or step has been carried out successfully and error-free. It means everything is proceeding according to schedule and there are no problems to be concerned about.

“StepStatusFail” indicates that a step or action was not carried out properly. It signals a flaw, mistake, or breakdown in that phase that must be fixed to continue with the work or procedure.

How can we use PZinsky to import rules?

Assuming you meant Python’s z3 library, as “PZinsky” is not recognized, you take the following actions to include or bring in rules using PZinsky:

Import the Library: The z3 library should be imported into your Python script. This is accomplished using the import z3 command.

Define Rules: Using the tools supplied by z3, formulate your logical rules. These guidelines explain logical connections, equations, and limitations.

Verify Satisfiability: To determine whether your rules can be true under specific circumstances, use z3.

Solve or Analyze: You can solve equations, examine limitations, or identify workable solutions using the rules you’ve established, depending on your use case.

Which workspaces are compatible with the most recent version of Pega?

App Studio: It is multichannel, assists with UI creation, and can be used to create applications without writing a single line of code.

Prediction Studio: Pega uses its integrated AI capability and decision-making to identify the optimal course of action.

Admin Studio: It essentially oversees all of your apps’ runtime conditions, security, users, and cloud performance.

Dev Studio: It assists developers in exploring Pega’s more sophisticated features.

What classes is PRPC (Pega Rules Process Commander) capable of supporting?

Business process management, customer relationship management (CRM), decision management, and case management systems can all be developed and implemented using the PRPC framework. Pega PRPC is an automated backend tool that runs on Java.

The several classes that PRPC supports are as follows:

Base Class: This is the highest-level base class; Work-, Data-, Rule-, Assign-, History-, and so on are some of its offspring. Concrete classes and abstract classes are the only class types that Pega supports.

Abstract Class: Classes that end in ‘-,’ are known as abstract classes since they are unable to produce instances of work objects.

Concrete Classes: Concrete Classes will create instances of work objects and do not end in ‘-‘.

How can one distinguish between utility and activity?

“Activity” and “utility” are components of functionality in Pega. Activities that frequently involve data processing or decision-making are similar to detailed instructions that inform the system what to do. Conversely, utilities are compact, reusable processes that carry out particular tasks, such as validations or calculations. Consider utilities as specific tools used within activities to facilitate tasks, and consider activities as comprehensive plans for a task. Both support the development of streamlined and well-organized business processes in Pega applications.

What are the different types of locking in Pega?

Locking entails taking control of a work item before beginning any actions on it and making sure that only one user works on it at once. Locking can take two forms, as shown below.

Default Locking: By default, only one user can work on a work object at a time.

Optimistic Locking: A new feature in Pega 7 is called “optimistic locking,” which enables multiple operators to work on the same object at once.

What is forward chaining, exactly?

Every time one of the input property values changes, forward chaining executes the declarative rule to carry out automatic property computation.

Forward chaining, for instance, causes the perimeter property of a circle to be recalculated if the radius value changes and if the perimeter property depends on the radius values.

What is backward chaining?

By executing the declarative rule when the property’s value is needed rather than when an input changes, backward chaining automates the computation of the property.

Every time the area property is required, for instance, it is recalculated if the area property depends on the length and width parameters.

How should we handle escalation?

Escalation is the term used to describe any procedure within a Process Commander application that makes high-priority work objects accessible to managers and users and triggers their prompt processing. Escalation may occur as a result of Pega-ProCom agent background processing or a service level rule associated with the flow.
