Certified Information Systems Auditor (CISA) — Question 1327

An organization recently migrated its data warehouse from a legacy system to a different architecture in the cloud. Which of the following should be GREATEST concern to the IS auditor reviewing the new data architecture?

Answer options

• A. The cloud data warehouse uses a hybrid cloud architecture.
• B. There is increased latency in the data source synchronization to the cloud data warehouse.
• C. The migration analyst is not fully trained on the new tools.
• D. The data was not cleansed before moving from the source to the cloud data warehouse.

Correct answer: D

Explanation

The greatest concern is that the data was not cleansed before transferring to the cloud data warehouse, as this can lead to inaccuracies and poor quality data. While the other options raise valid points about architecture, latency, and training, they do not directly impact the integrity of the data as significantly as failing to cleanse it before migration.
