CIS CIS Data Migration & Integration 2

Question 1

In CIS integration design, what is an API (Application Programming Interface) PRIMARILY used for?

Accepted Answer

Defining how software components communicate and exchange data

Answer

An API defines the rules and protocols for how different software applications communicate and share data with each other.

Question 2

What is the purpose of a data reconciliation step after a CIS migration?

Accepted Answer

To verify that migrated data in the target matches the source data accurately

Answer

Data reconciliation validates that record counts, key values, and data integrity in the target system match the source, confirming migration success.

Question 3

Which integration pattern uses a central hub to route messages between multiple systems, reducing point-to-point complexity?

Accepted Answer

Hub-and-spoke (ESB) pattern

Answer

The hub-and-spoke pattern, often implemented with an Enterprise Service Bus (ESB), centralizes integration logic and reduces the number of direct connections needed.

Question 4

During CIS migration testing, a 'mock migration' or 'dress rehearsal' is performed to:

Accepted Answer

Practice the full migration process in a non-production environment to identify issues

Answer

A mock migration rehearses the entire cutover process in a test environment so that timing, sequencing, and potential errors can be identified before go-live.

Question 5

What does 'idempotency' mean in the context of CIS API integrations?

Accepted Answer

Calling the same API operation multiple times produces the same result as calling it once

Answer

An idempotent API operation can be safely retried multiple times without causing duplicate or inconsistent results, which is critical for error recovery.
