The SMB (Server Message Block) protocol, which is primarily used for Windows-based file sharing, relies on a centralized authentication and authorization mechanism to manage permissions in an enterprise environment. In Huawei OceanStor NAS documentation, Active Directory (AD) is the primary domain controller system supported for the SMB protocol.

When a Huawei storage system joins an Active Directory domain, it can authenticate users and groups defined in the AD, allowing for seamless integration with Windows environments. WhileLDAP (Option A)andNIS (Option B)are supported by Huawei NAS for theNFSprotocol (typically used in Linux/Unix environments), the SMB protocol is inherently designed to work with the Kerberos and NTLM authentication provided by Microsoft’s Active Directory. This ensures that NTFS-style ACLs (Access Control Lists) can be properly mapped and enforced across the network.

According to Huawei’s technical standards for data protection, this statement is the reverse of the actual definitions. Backup focuses on data recoverability, while Disaster Recovery (DR) focuses on service continuity.

Backup is the process of creating a redundant copy of data to protect against accidental deletion, data corruption, or hardware failure. Its primary goal is to ensure that a copy of the data exists and can be restored (recoverability). Disaster Recovery, however, involves the infrastructure and processes required to resume business operations (services) after a catastrophic event (like a flood or fire). DR utilizes technologies likeHyperMetro(active-active) orHyperReplication(remote replication) to ensure that the application remains available or can be restarted quickly at a secondary site, thereby ensuringService Continuity. Because the statement swaps these two core objectives, the answer is False.

A Storage Area Network (SAN) is a dedicated network for block-level data access. Huawei OceanStor systems support a variety of block-access protocols to ensure compatibility with different infrastructure environments. Fibre Channel (FC) is the industry standard for high-performance enterprise SANs, offering dedicated, low-latency, and lossless delivery. iSCSI provides block-level storage over standard TCP/IP Ethernet networks, making it a flexible and cost-effective alternative for many organizations.

InfiniBand (Option B)is a high-bandwidth, low-latency interconnect protocol often used in High-Performance Computing (HPC) and specialized SAN clusters to connect compute nodes to storage pools at extremely high speeds.NFS (Option D)is excluded from this answer because it is aNAS (Network Attached Storage)protocol. NFS (Network File System) provides file-level access rather than block-level access. While modern Huawei systems like the OceanStor Dorado series are "Unified Storage" (supporting both SAN and NAS on the same hardware), technically, only A, B, and C are considered SAN protocols.
