Your organization shall preserve accounting transactions for at least ten years per regulatory requirements. After conducting data analytics, you discover that transactions stored in the database for more than one year and might be reused or queried account for 5% only. Which of the following is the least concern in terms of enforcing the regulatory mandate?
A. Hierarchical storage management (HSM)
B. Data retention policy
C. Backup validation
D. Offsite tape vaulting

Kindly be reminded that the suggested answer is for your reference only. It doesn’t matter whether you have the right or wrong answer. What really matters is your reasoning process and justifications.

My suggested answer is A. Hierarchical storage management (HSM).

Requirements for Data Availability

To preserve accounting transactions for at least ten years per regulatory requirements means the organization must retrieve and present any data once requested by the authorities.

• A regulatory policy, the data retention policy for this case, is set out to reflect the regulatory requirements.
• The data backup must be validated, or the data availability may be hindered by humidity, temperature, hardware defects, technical issues, or any other issues.
• Offsite tape vaulting or offsite backup should be in place just in case if the local copy is unavailable.

HSM as Cost-Saving Solution

Hierarchical storage management (HSM) is least related to data availability. It is a data storage technique that automatically moves data between high-cost and low-cost storage media in terms of cost-saving.
