Huawei HCIE-Storage (Written) : H13-629

A research unit purchased a Huawei Oceanstor 9000 storage products, the main configuration products: 8 * Oceanstor 9000 C node, the front end 10GE * 2, CE6850 switch * 2, S5700 switch * 1, cables, lighting and other accessories are fully furnished, households communication deployment program, prepared in advance a list of IP planning programs and IP requirements. Which of the following IP address is needed? (Multiple choice.)

• A. The customer management network must be interoperable with the OceanStor 9000 InfoEqualize DNS IP to access the OceanStor 9000 storage.
• B. The client needs to provide 49 IP addresses that can interoperate with client applications, 16 for the static front end, 32 for the dynamic front end, 1 for InfoWqualizer DNS IP.
• C. Customers need to provide nine management network IP addresses, of which eight for IPMI management, one for OM management.
• D. The customer needs to provide 16 IP addresses for Oceanstor 9000 system back-end IP and need to provide a gateway.

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 thefollowing statement is correct? (Multiple choice.)

• A. 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 placed in a consistency group.
• B. The automatically created Asynchronous Remote Copy snapshot can either be a private quick pick or a public one.
• C. In a DR scenario, it is recommended to create a virtual snapshot of thesecondary LUN and map it to the host for access.
• D. In remote replication link networking, parallel networking is better than crossover networking.

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?

• A. 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
• B. 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
• C. 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 needto be met:1. remote copy pair health status is normal, and the copy link is normal2. from the directory has been canceled write protection
• D. If the replication link is down, you can only modify the pair attribute in the cluster where the home directory ofproduction site A resides. After the replication link is restored, the modifiedThe pair attribute is automatically updated to the production site from the directory

True or False, in an OceanStor V3 series storage array, all the snapshots of a LUN occupy not more space than that of the LUN.

• A. True
• B. False

In an OceanStor V3 storage system, a disk domain has multiple types of disks. If one SAS disk is added to the disk domain, all disks of the disk domain will participate in data balancing.

• A. TRUE
• B. FALSE
