NEW QUESTION # 190
A company purchased a set of Huawei hybrid flash storage equipment to provide NAS (Network Attached Storage) services for the three departments of finance, personnel and technology. The current network environment is as follows:
1) The clients are all Windows operating systems and join the same AD (Active Directory) domain;
2) The clients and storage systems of the three departments are in the same local area network.
For the allocation of storage space, the requirements are as follows:
1) Each of the three departments uses 1TB of dedicated storage space;
2) Each employee can read and write to their own private directory;
3) Private directories between employees are invisible to each other.
How can storage engineers plan NAS services to meet the above requirements? (Multiple Choice)
- A. Create file systems for the three departments, each with a size of 1TB
- B. Set rules for different Homedir shares to enable employees to have their own private directories
- C. Add the storage to the AD (Active Directory) domain environment and configure the mapping rules for CIFS Homedir
- D. Adopting CIFS Homedir sharing method can meet the storage space requirements for the three departments
Answer: A,B,C

Set some parameters to improve performance of NFS mounted under the Linux operating system. Which of the following description is correct?
- A. Nolock, if there is a shared file between NFS clients, you can use this parameter. Reduce service- side file lock overhead.
- B. Async, allowing asynchronous data write, synchronous write requirements. NFS server must brush each data into the hard disk before it can return success delay higher.
- C. Noatime, if you do not need to record the file access time, you can increase this parameter to avoid frequent access, modify the access time to open pin.
- D. Rsize / wsize, read and write the maximum size of each block, it is recommended to adjust to the maximum. General Linux operating system environment, the maximum value of 1M.
