Pega LSA CSSA design level interview questions

Prepare for the interview confidently.

1. Explain the process of SSO with SAML and how it works?

2. How does the operator provisioning works while authenticating and can we create operator on the fly?

3. What is the process to update the operator record while authentication happens with SAML or OpenID connect?

4. Explain how authentication mechanism works for services provided from Pega application with OAuth2.0?

5. How to secure the data exchange between the systems?

6. Explain the detailed steps followed for designing the application architecture before implementation and what are the documents produced in this process?

7. How do we identify what data elements, data structure and type required before implementation as part of the design?

8. What is the thought process that we should have before designing the application components (ex: application structure, classes, rulesets, data model etc)?

9. How to provide asynchronous service from pega application if high number of requests are coming in?

10. What are the performance issues that we may face when high number of requests are coming in and how to make our pega REST service effective in terms of performance and cater the requests with minimal turnaround time?

11. How to perform data migration while working on Pega migration from on premise to cloud?

12. What are the steps to follow while the upgrade is required? How do you plan for larger development projects?

13. If a parent case has multiple child cases and nested child cases. Two users are trying to work on child cases at the same time and submitted with a fraction of sec difference. But both the users are trying to update same data record in the background. How does locking works and what happens to the data record updation?

14. How to secure the integration components connecting to the external systems and how to secure the data transmission (data-in-transit)?

15. What mechanism we should follow to secure the data in Pega?

16. How to debug and resolve any issues happening with real time data flows?

17. If millions of data should be read and create cases in Pega for each of the record, what design do you suggest?

18. If millions of data should be read but remove the duplicate records and create cases in Pega for each of the record, what design do you suggest?

19. If the data is present in the file, that needs to be read, processed and create cases with in pega, what design do you suggest?

20. If the file is too big which needs to be read, processed and create cases with in Pega, without impacting the performance and with less turn around time how to process the data?

21. In the skimming process, what rules would go into new rulesets and what rules are discarded?

22. Scenario: The user is trying to login into the external application. Some one hijacked the access so user tried to request the login recovery. How do we design this process in Pega to cater large number of login recovery requests to be resolved when they raise the requests from the company website?

23. If Pega is trying to request external source multiple times in a day for mostly redundant data with different parameters may be. Due to the overwhelming of the requests the performance is hit badly. How do we resolve this issue and make sure the data is available for best of use without hitting the service every time?

24. Based on the user's region (US, EU etc) pega should call different external services and update the external data source. What is the best design that would always work even though the region value changes dynamically?

25. How does pega mashup's authentication works?

26. What are the key store types allowed in Pega? And why do we need key store?

27. What is the difference between parameterized data page and keyed data page?

28. How to setup BIX with Pega? What process we should follow to export the files from Pega to external file storage with in the organization while using Pega cloud?

29. How do i read multiple files using the same data set with in a data flow without running the data flow/data set multiple times?

30. In what scenarios, as a solution Pega is not a good fit? When do you suggest customer to use Pega and not to use Pega?
