Question 570
Management reports that this issue has been corrected: A cloud move assumes existing encryption keys will work in the target without import or custody testing. Which result would provide the STRONGEST assurance that the issue is corrected?
- A migrated encrypted sample is accessible to authorized users and remains protected.
- Target balances, exceptions and sampled loan histories reconcile to source records.
- Invalid or manipulated requests are blocked and legitimate transactions remain correct.
- Sample and aggregate source-to-target totals agree or documented exceptions are resolved.
Explanation
Correct Answer
A:A migrated encrypted sample is accessible to authorized users and remains protected. It addresses system migration, infrastructure deployment, and data conversion. Underlying audit concern: Migration design must preserve cryptographic dependencies and data accessibility.
Incorrect Answers
B:Target balances, exceptions and sampled loan histories reconcile to source records. This would be relevant to a different issue such as: A bank converts 20 years of loan records into a new core system and reconciles only total record counts. In the present case, the most directly relevant verification is: A migrated encrypted sample is accessible to authorized users and remains protected. The governing distinction is: Migration design must preserve cryptographic dependencies and data accessibility.
C:Invalid or manipulated requests are blocked and legitimate transactions remain correct. This would be relevant to a different issue such as: A payment API relies on user-supplied transaction values without server-side validation. In the present case, the most directly relevant verification is: A migrated encrypted sample is accessible to authorized users and remains protected. The governing distinction is: Migration design must preserve cryptographic dependencies and data accessibility.
D:Sample and aggregate source-to-target totals agree or documented exceptions are resolved. This would be relevant to a different issue such as: A data migration design encrypts transfers but does not detect missing or duplicated customer records. In the present case, the most directly relevant verification is: A migrated encrypted sample is accessible to authorized users and remains protected. The governing distinction is: Migration design must preserve cryptographic dependencies and data accessibility.
Question 571
An IS auditor evaluates this situation: An inventory API responds successfully while silently truncating long product descriptions during integration. Which audit principle MOST directly applies to this situation?
