NetApp NS0-005 Exam - Topic 3 Question 19 Discussion

Explanation

WORM (Write Once, Read Many): This is the correct technology for legal and regulatory data retention. It locks data so that it cannot be modified or deleted for a specified retention period (in this case, 7 years). NetApp implements WORM technology through a feature called SnapLock.

NVE (NetApp Volume Encryption): This is a software-based encryption solution for data security (protecting against data theft), but it does not prevent data from being deleted or modified by authorized users.

WAFL (Write Anywhere File Layout): This is the underlying file system layout used by NetApp ONTAP to optimize write performance. While it is fundamental to how data is stored, it is not a compliance feature for legal holds.

NSE (NetApp Storage Encryption): This is a hardware-based encryption solution using self-encrypting drives (SEDs). Like NVE, it protects data confidentiality, not data retention or immutability.
