AI Explanation

To answer this question, you need to understand the concepts of SAN (Storage Area Network) and NAS (Network Attached Storage).

Option A) SAN and NAS - This option is correct because both SAN and NAS are network storage systems that allow computers to share large volumes of data across high-speed LAN connections.

Option B) SAN - This option is incorrect because SAN alone does not provide the capability to share data across LAN connections. SAN is a dedicated network that connects storage devices to servers and provides block-level access to data.

Option C) NAS - This option is incorrect because NAS alone does not provide the capability to share data across LAN connections. NAS is a file-level storage system that connects to a LAN and allows multiple devices to access shared files.

Option D) TSM - This option is incorrect as TSM (Tivoli Storage Manager) is a data protection and backup software, not a network storage system.

The correct answer is A) SAN and NAS. This option is correct because both SAN and NAS provide the capability to share large volumes of data across high-speed LAN connections.
