(1) share named cifs_dir_001

(2) read-only access

(3) Using local authentication user mode, user name cifsuser001, password Password @ 123;

One of the front-end IP addresses of the OceanStor 9000 storage system is 96.69.35.7.

Which of the following descriptions is correct?

Options:

Enter the windows 7 PC \\ 96.69.35.7, prompted to enter the user name password, see the shared path name ing into cifs_share_001

directly in the address bar enter \\ 96.69.35.7 \ cifs_dir_001 and enter the user name password, you can open the shared path, you can browse this totalEnjoy the file under the path

In the address bar, type \\ 96.69.35.7 \ cifs_dir_001 \ a.txt, follow the prompts to enter the user name password, you can not open the a.txt file

in the address bar enter \\ 96.69.35.7 \ cifs_dir_001, you can create a new file in this path B.doc

Questions # 13:

Production time is Monday to Friday 8:00 to 18:00. There are three LUNs, respectively LUN1, LUN2, LUN3, LUN1 with a size of 500G, all IO.

The average response time needs to be within 5ms, the size of LUN2 is 4TB, the coexistence of hot and cold data (with 12.5% of the hot data), and the size of LUN3 is 10TB. If performance requirements are not high and the engineer plans to use SmartTier, which of the following description is correct? (Multiple choice)

Options:

Use 3-tier Tier, 1TB high performance layer, 4TB performance layer, 10TB capacity layer, and configure LUN1 to allocate high-performance layer capacity first, LUN2 preferentially allocates performance layer capacity and LUN3 preferentially allocates capacity layer capacity

Use 3-tier Tier, 1TB high-performance layer, 4TB performance layer, 10TB capacity layer, configure LUN1 and LUN2 to migrate automatically, and LUN3 priority allocation of low-performance layer capacity

The use of 3-tier Tier, high-performance layer 1TB, performance layer is 4TB, capacity layer is 10TB, while configuring LUN1, LUN2, LUN automatic relocation. The LUN3 is migrated preferentially to the low-performance layer

Set the monitoring period of the Smart tier to 8:00 to 18:00 every day from Monday to Friday. The migration period is not overlapped with the monitoring period

Questions # 15:

One customer purchased two Huawei OceanStor 9000 storage devices and deployed them in A and B cities respectively and configured the InfoReplicator function. Regarding production site A data reliability, which of the following descriptions is wrong?

Options:

Due to system upgrades, you need to make a master-slave switchover for the remote replication pair that has been created, and the following conditions need to be met:1. remote copy pair health status is normal, and the copy link is normal2. from the directory has been canceled write protection

If the replication link is down, you can only modify the pair attribute in the cluster where the home directory of production site A resides. After the replication link is restored, the modifiedThe pair attribute is automatically updated to the production site from the directory

Set the channel authentication IP address, which is the static front-end service IP address of any node in the remote cluster, and is used to establish a replication area channelConnection, this node must be in the copy area

The channel authentication password can be modified. After the password is modified, if the copy link is disconnected, you need to manually re-enter the new password and keep the passwordThe password of the originating and receiving ends of the channel in the system is consistent so that the duplicated link can be recovered

You build the cluster configuration using the wizard and part of the description shows that the quorum disk and resource disk can not be online. The following statement is correct regarding this scenario:

Options:

The shared disk file system uses the GPT format that caused the quorum disk to fail Online

The quorum disk can not be online due to the cluster feature that does not enable multipathing software

The MSCS Cluster service does not bring the volume resource online. The resource disk can not be online

Heartbeat network timeout causes arbitration disk and resource disk probability online
