In the context of data storage systems, "data types" often refer to the primary methods of organizing and accessing data. File and object are two of the three primary data access methods, the third being block. File-based storage (e.g., NAS) organizes data in a familiar hierarchy of directories and files. Object-based storage manages data as discrete units called objects, each containing data, metadata, and a globally unique identifier. NetApp ONTAP is a unified system that supports both file (NFS/SMB) and object (S3) protocols, treating them as distinct data types.

C. disk: A disk is the physical or logical medium where data is stored; it is not a data access method or type.

D. LAN: A Local Area Network (LAN) is a communication infrastructure used to connect devices; it is not a type of data.

E. RAID: RAID (Redundant Array of Independent Disks) is a data protection and storage virtualization technology, not a data access type.

1. NetApp Official Documentation, "What is network-attached storage (NAS)?": This document defines NAS as a "file-level (as opposed to block-level) data storage architecture." This establishes "file" as a primary data storage type. (Source: NetApp, "What is Network-Attached Storage (NAS)?", retrieved from https://www.netapp.com/data-storage/nas/what-is-nas/)

2. NetApp Official Documentation, "What is object storage?": This resource describes object storage as a distinct "data storage architecture for handling large amounts of unstructured data," contrasting it with file and block storage. This confirms "object" as a fundamental data type. (Source: NetApp, "What is Object Storage?", retrieved from https://www.netapp.com/data-storage/object-storage/what-is-object-storage/)

3. NetApp ONTAP Documentation, "ONTAP S3 configuration overview": "You can use the ONTAP S3 object storage service to store and manage your object data on your ONTAP cluster." This section explicitly refers to managing "object data," reinforcing its status as a data type.

4. NetApp ONTAP Documentation, "NAS file access overview": "ONTAP provides Network Attached Storage (NAS) access to files for clients through a variety of protocols..." This documentation clearly delineates "file access" as a core capability, separate from other data access methods.
