A customer must store physical hard copies of transaction data off site to meet regulatory requirements. Which NetApp technology enables the customer…

The requirement is to store physical hard copies of data off-site, which in the context of data centers, refers to tape backups. Network Data Management Protocol (NDMP) is an industry-standard protocol used by NetApp ONTAP to enable backup applications to control the backup and restore of data between a storage system and tape devices. This allows for the creation of physical tape media that can be transported and stored at an off-site location, directly fulfilling the customer's regulatory compliance needs for physical, off-site data retention.

A. SnapVault: SnapVault is a disk-to-disk backup technology. It creates logical, point-in-time copies on a secondary ONTAP system, not physical media like tapes.

C. SVM DR: SVM DR is a disaster recovery solution that replicates an entire Storage Virtual Machine (SVM) to another cluster using SnapMirror. It is a disk-based replication method, not a tape backup solution.

D. FlexCache: FlexCache is a remote caching technology designed to accelerate data access for distributed clients. It is not a backup or archival solution.

1. NetApp ONTAP 9 Documentation

"Data protection using NDMP overview": "NDMP is a protocol that is used to transport data between an ONTAP system and a tape server. You can use NDMP to back up and restore data on your storage system." This document explicitly links NDMP to tape-based backup operations.

Section 2.1

"SnapVault Overview" describes SnapVault as a "disk-to-disk (D2D) data replication feature for ONTAP." This confirms it is not a tape-based solution.

Section 2.3

"SVM Disaster Recovery" states

"SVM DR replicates all of the data and configuration of a source SVM to a destination SVM on another cluster." This defines it as a disk-based DR technology.

"FlexCache Technology in ONTAP 9": Page 5

Section 1

"Introduction" describes FlexCache as a technology that "creates a sparsely populated

writable

persistent cache of an origin volume." This identifies its purpose as performance acceleration

not data protection.
