Question
An e-commerce customer's business system is deployed on Huawei Cloud. In order to meet the needs of multiple cloud servers to share files, the operation and maintenance personnel plan to realize the sharing of business data by mounting the NFS file system. Which of the following descriptions about the prerequisites for mounting NFS are correct? (Multiple choice)
Options
- AAt least one cloud server that is the same as the VPC to which the file system belongs
- BThe file system has been created and the mount address of the file system has been obtained
- CDetermine the operating system type of the cloud server. The commands for installing the NFS
- DIf you use the SFS Turbo file system, you need to configure domain name resolution first

Explanation
All four options are correct because they each represent a genuine prerequisite for successfully mounting an NFS file system on Huawei Cloud. Option A is required because NFS communication happens over a private network, and a cloud server must share the same Virtual Private Cloud (VPC) as the file system to have network-level access to it. Option B is self-evident but critical: the file system must exist before it can be mounted, and the mount address (the endpoint provided by SFS) must be known to form the correct mount command. Option C matters because Linux and Windows servers use fundamentally different NFS client packages and mount commands, so identifying the OS beforehand ensures the right software is installed and the correct syntax is used. Option D applies specifically to SFS Turbo, which uses domain-based mount addresses rather than plain IP addresses, meaning DNS resolution must be configured on the server or it will fail to resolve the endpoint.
Since this question has no wrong choices, the exam is testing whether candidates can identify all the necessary conditions together rather than dismissing any as optional.
Memory tip: Think of the four prerequisites as a checklist in order of dependency - Network access (A), then the Resource itself (B), then the right Tools for your OS (C), then special DNS setup if using Turbo (D). No step can be skipped.
