Questions # 51:

What value can the HP UN order lvextend-m parameters be set? (Multiple choice.)

Options:

Unlimited

Answer

B, C

Questions # 52:

Disaster recovery project information research mainly includes information about who, what, and why. What is the following information background? (multiple choice)

Options:

A bank has more than XXcustomers and XX corporate customers.

Data loss will be huge and business disruption may result in significant financial loss.

Business interruption has a huge impact, and the interruption time in business deployment is less than 2 hours.

Clientswant to build two live-action data centers in the same city to realize the key business activities such as RTO 2.

Answer

C, D

Questions # 53:

A TV station plans to adopt Huawei OceanStor 9000 as a back-end storage system, with 10 OceanStor 9000 C nodes, planned to be deployed in 4 standard cabinets, with all backends connected to a pair of stacked back-end CE6850 switches. There is no single customer in the existing networking standalone management network. Which of the network IP address planning described below is incorrect?

Options:

You can plan back-end storage network for 9000 internal communications, without planning gateway address, and front-end network with the same network segment IP address.

Oceanstor 9000 front-end network and management network can be considered together, planning for the same network segment.

Back-end CE6850 switches need to use four stacked cables for stacking connection to ensure bandwidth requirements

The external NTPserver address and the Oceanstro 9000 front-end network need to communicate to ensure that the oacenstor 9000 system and client applications maintain time synchronization.

Answer

Questions # 54:

When planning an OceanStore Unified Storage Arraysynchronization remote replication, which of the following description is correct. (Multiple choice.)

Options:

In the scenario where the actual RPO indicator requires zero, you can choose to synchronize remote replication.

Synchronous remote replication canbe used to map the main and secondary storage of the two sets of LUN mapping to the host to create a scenario volume.

Synchronous remote replication on the remote disaster recovery can be well done.

Because synchronous remote replication does not usesnapshots, after synchronous remote replication is interrupted abnormally, the data on the primary LUN needs to be resumed in reply.Start synchronization to the slave site.

Answer

A, B

Questions # 55:

Which of the following is not a disasterrecovery manual restart configuration necessary to restore the production system (Multiple choice.)

Options:

Stop the current production business

Add the remote device to the original production array

With the disaster recovery array as the master LUN and the original production array as the slave LUN, create the remote replication relationship between the DR and the production end and wait for the initial synchronization to be completed.

Make an incremental synchronization.

Delete theoriginal production array consistency group.

Answer

B, E

Questions # 56:

In a A VTL6900-I system, the backup server connected to it is the Linux operating system. The backup server and the VTL6900-I system are directly connected through the FC.

The server identifies the device information as shown below. After the backup server is configured as a backup client for the VTL6900-I system and the backup VTL system on the server virtual library process, which the following operation and description is correct:

(Multiple choice.)

Options:

When configuring the backup client on the VTL side, you need to know that the WWPN of the FC port that connects the VTL to the VTL is available on the server in the sys /class / fc_host directory and subdirectory to the corresponding WWPN port.

Server-sideidentification has been detected with the library device command is cat / proc / scsi / scsi.

As shown in the figure, among the devices identified on the server side, the device labeled 1 is the scanned library.

As shown in the figure, of the devices identified on the server side, the device labeled 2 is the information for the scanned tape.

Answer

A, B, C

Questions # 57:

The client environment is the HP-UX11i v2 operating system, the HBA is the AD193A, and the operating system comes with the driver. The storage array is Huawei OceanStor V3. When the LUN mapping between HP-UX and the storage system is completed, you can not change the topology mode of the FC host interface card on the storage system.

Options:

True

False

Answer

Questions # 58:

Huawei Standard Edition N8500 has two nodes named Pubeth1 and Pubeth4. It opened the NFS service. NFS server accepts recovery after NFSguest.

However, the 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?

Options:

Restart the NFS server of the N8500

Restart the client's NFS service

Reseat the NFS client network cable

Forcibly unmount the NFS client mount point and mount it again

Answer

Questions # 59:

A Huawei OceanStor 9000 is externally shared using NFS and CIFS at the moment.

You want to set some parameters to improve the performance of theNFS mounted under the Linux operating system. Which of the following description is correct?

Options:

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.

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.

Noatime, if you do not need to record the file access time, youcan increase this parameter to avoid frequent access, modify the access time to open pin.

Nolock, if there is a shared file between NFS clients, you can use this parameter. Reduce service-side file lock overhead.

Answer

A, B, C

Questions # 60:

An Engineer installed a OceanStor 9000 for a customer (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. During the installation there were issues. Which of the following description of these issues are correct? (Multiple choice.)

Options:

5 devices TOE NIC A0, B1, and A0, B3 inserted into the PCIe slot will not affect the system. Deployment will not affect the network bandwidth, so it cannot be adjusted.

The signal cables are long and need to be strapped to the cabinet or placed on the bottom tray.

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 positionB3-0, due to the same network card two network port peer, you can place the wrong line, you cannot adjust.

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. You can base this software debugging.
