Question 1
A hospital bought a Huawei OceanStor 9000V100R001C30 storage device for storing business data. According to the relevant laws and regulations, which of the following example descriptions of disease preservation of system data using InforLocker function is wrong:
A. The engineer has set the WORM root directory according to the hospital's requirements, and all the subdirectories under this directory have the WORM attribute.
B. During the file protection period, no one can delete the protected file.
C. Protected Documents are Protected for a Period of 70 Years on Huawei OceanStor 9000 Storage Device.
D. WORM log save root, quota and WORM protection period cannot be set.
Question 2
N8000 clustered NAS system to provide file system sharing services, surface VxFS file system and roll features the correct statement:
A. VxFS is a non-log file system that can support more than 2T files.
B. File system snapshot using copy-on-write (copy-on-write technology) and other files together, share partition or volume storage space.
C. Provide file system-level snapshots, copy.
D. File System Snapshots, Scenarios, Replication, etc. Features are based on Storage Checkpoint.
Question 3
In an OceanStor V3 system storage array, all the snapshots of a LUN occupy no more space than the LUN.
A. True
B. False
Question 4
When the client adopts the SMB 1.0 / 2.0 / 2.1 / 3.0 protocol, while performing file replication inside Huawei OceanStor 9000, it does not need to pass through the client, but directly in the system to tell the completion.
A. True
B. False
Question 5
Client1 needs to read file X from Huawei OceanStor 900 and the node that responds to the read request is node A.Choose the process, which of the analysis is correct:
A. If the system has monitored the file X has been cached on Node B, the client client1 can read the file directly from Node B.
B. If the system monitors that node B has cached file X, then node A can read the file from node B.
C. After HUAWEI OceanStor 9000 processes the request for reading the file X from client1, the system reserves the message on both node A and node B.
D. If the system monitors that node A has cached file X, then node A only caches the data of file X and does not cache its verification data
Question 6
For commonly used SQL Server 2005 and 2008, users can connect to the specified server through the SQL Server Management Studio tool Database Engine.There are two connections in the connection group authentication method. Which method client application connection to provide the required landing User ID and password?
A. SQL Server Authentication
B. Windows authentication
C. Log in as superuser
D. Other ways when landing
Question 7
Engineer installed a customer unit for OceanStor 9000 equipment installation (a total of 5 OceanStor 9000 C Node, front and rear ends are 10GE TOE networking, on-site installation TOE network card). Then connected the signal lines, power lines, and debugged the software. In the period of project tension, the hardware installation process has some of the following phenomena. Which of the following description of these phenomena is correct? (Multiple choice.)
A. 5 devices TOE NIC A0, B1, and A0, B3 have these two ways, as are inserted in the PCIe slot, will not affect the system. Deployment will not affect the network bandwidth, so it cannot be adjusted.
B. The signal cables are long and need to be strapped to the cabinet or placed on the bottom tray.
C. Label NODE 01 A0-0 The signal cable is inserted in the network port A0-1. The signal cable labeled NODE01 B3-1 is inserted in the network position B3-0, due to the same network card two network port peer, you can place the wrong line, you cannot adjust.
D. CE6850 switch connected to two stacked copper cables, one of which is needed to post-cold more cold, because it does not affect the network interoperability.
Question 8
A customer deploys a set of OceanStor V3 storage in two cities and adopts asynchronous remote replication networking between the two storage arrays. Which of the following statement is correct? (Multiple choice.)
A. The automatically created Asynchronous Remote Copy snapshot can either be a private quick pick or a public one.
B. In a DR scenario, it is recommended to create a virtual snapshot of the secondary LUN and map it to the host for access.
C. In remote replication link networking, parallel networking is better than crossover networking.
D. The number of LUNs in the consistency group should be as small as possible, and only the LUNs that have write dependencies on the same application are
Question 9
Huawei Standard Edition N8500 has two nodes the business mount Pubeth1 and Pubeth4. It opened the NFS service. NFS server except recovery after NFS guest.Client mount point can not be accessed into the directory for a long time without echo. What do you need to do to fix it?
A. Restart the NFS server of the N8500
B. Restart the client's NFS service
C. Reseat the NFS client network cable
D. Forcibly unmount the NFS client mount point and mount it again
Question 10
Huawei OceanStor 9000 external shared mainly NFS and CIFS at the moment.Set some parameters to improve performance of NFS mounted under the Linux operating system. Which of the following description is correct?
A. 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.
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. Nolock, if there is a shared file between NFS clients, you can use this parameter. Reduce service-side file lock overhead.
