When delivering a flash storage project, Huawei engineers introduced the multi-tenant feature of flash storage to the customer. This feature isolates service dat a. Although different tenants cannot access each other’s LUNs, they can access each other’s file system.

The statement is false. The core purpose of a multi-tenant feature in any storage system, including Huawei OceanStor Dorado, is to provide secure and isolated environments for different tenants. This isolation applies to all data resources. While the first part of the statement is correct ("different tenants cannot access each other’s LUNs"), the second part ("they can access each other’s file system") is fundamentally incorrect. Data isolation in a multi-tenant environment must be comprehensive, preventing tenants from accessing each other's block resources (LUNs) and file resources (file systems, shares, dtrees). Allowing cross-tenant access to file systems would constitute a major security vulnerability and defeat the primary objective of the feature.

This question is of the True/False type. The alternative, "True," is incorrect because it describes a system with a critical security flaw, which is the opposite of what a multi-tenancy feature is designed to achieve. The principle of multi-tenancy is built on the foundation of strict resource and data isolation between tenants.

Huawei OceanStor Dorado 6.1.2 "Security Configuration Guide", Chapter: "Service Security Configuration", Section: "Multi-Tenant". This section describes the feature as a mechanism to partition storage system resources for different tenants, ensuring that tenants' services and data are securely isolated from one another. This isolation explicitly covers both block and file services.

Huawei HCIP-Storage V5.0 Training Material (H13-624), "Chapter 5: Huawei Converged Storage Key Features", Section: "Multi-Tenant". The training material explains that multi-tenancy allows an administrator to create virtual storage systems (vStores) to isolate resources and data for different users or departments, preventing unauthorized cross-access.
