CIS CIS Data Migration & Integration 3

Question 1

Which type of testing validates that data moved during a CIS migration is complete, accurate, and consistent in the target system?

Accepted Answer

Data validation testing

Answer

Data validation testing specifically checks migrated records for completeness, accuracy, referential integrity, and consistency in the target system.

Question 2

A 'rollback plan' in CIS data migration is critical because:

Accepted Answer

It provides a tested path to restore the legacy system if the migration fails

Answer

A rollback plan defines the exact steps to revert to the legacy system if critical failures occur during cutover, minimizing business disruption.

Question 3

What is the primary risk of a 'Big Bang' data migration approach in a CIS implementation?

Accepted Answer

All data is migrated at once, creating a single large high-risk cutover event

Answer

Big Bang migration moves all data in one event, which concentrates risk into a single cutover window and leaves little room for error recovery.

Question 4

In CIS integration architecture, a webhook differs from a REST API polling approach in that:

Accepted Answer

Webhooks push data to the consumer automatically when an event occurs

Answer

A webhook automatically pushes data to a predefined URL when a triggering event occurs, eliminating the need for the consumer to repeatedly poll for updates.

Question 5

What is the significance of a 'freeze period' immediately before a CIS data migration cutover?

Accepted Answer

No new data changes are allowed in the legacy system to ensure a clean final data extract

Answer

A data freeze stops changes in the legacy system before the final migration extract, ensuring the migrated dataset is complete and consistent.
