Explanation

NAS (Network Attached Storage) and SAN (Storage Area Network) are the correct answers because both are dedicated, network-connected storage systems designed to be integrated ("plugged in") to an existing IT infrastructure - NAS provides file-level access over a standard network, while SAN delivers high-performance block-level storage over a dedicated storage network.

NFS (Option C) is a distractor because it is a protocol (Network File System) used to access files over a network, not a storage solution itself - NFS is often used on top of NAS, but it is not storage hardware or an architecture.

DAS (Option D) is wrong because Direct Attached Storage is physically connected to a single server, not networked or "plugged in" to shared infrastructure, making it the least flexible and least shareable option.

Memory tip: Think "Network = Plug-in." Both correct answers (NAS and SAN) contain "N" for Network - they connect to your infrastructure over a network. If it's a protocol (NFS) or direct (DAS), it doesn't count.
