Huawei HCIE-Storage V3.0 - H13-629_V3.0 Exam Practice Test

A. IPSAN

B. DAS

C. FC

D. NAS

A. The front-end network and management network of Huawei OceanStor 9000 can be considered together and planned to be on the same network segment.

B. The back-end CE6850 switches need to use 4 stacking cables for stacking connection to ensure bandwidth requirements.

C. External NTP Servex: The address needs to communicate with the front-end network of Huawei OceanStor 9000 to ensure that the Huawei OceanStor 9000 system and customer applications maintain time synchronization.

D. The back-end storage network is used for the internal communication of Huawei OceanStor 9000.
There is no need to plan the gateway address. It can be planned as an IP address on the same network segment as the front-end network.

A. Use convergent storage pools.

B. Support volume (SAN) and file system (NAS) in parallel dual stack mode.

C. Standalone SAN Engine and Standalone File Engine

D. Supports data duplication and compression of file system data.

A. For the damaged file system in the mounted state, directly execute fsck to repair it.

B. File system faults can be located by collecting log information from the /var/flog/message host.

C. You can use the mount command to check whether the mount status of the file system is read- only.

D. Do not arbitrarily perform fsck on a normally running file system.

A. While choosing the backup strategy, the enterprise should plan and design the backup window and recovery window at the same time

B. For operating system application software, only one incremental backup needs to be made after each system update or new software installation

C. The OA system is suitable for growth and backup, and a full backup is done monthly or weekly

D. The ERP system is suitable for a full back up every day

A. Snapshots do not support nesting, that is, under the directory where a snapshot has been created, neither the parent directory nor the subdirectory can create snapshots.

B. Hard links are protected by snapshots, and soft links are not protected by snapshots

C. For snapshots with an expiration time set, after the snapshot expires, the system will automatically delete the snapshot but not reclaim the storage space occupied by the snapshot data

D. The snapshot root directory (that is, the directory where the snapshot was created) does not support deletion.

A. Backup Solutions

B. Disaster Recovery Solution

C. Archiving Solutions

D. Copy Solutions

A. Use Lightweight Directory Access Protocol (LDAP) for access control.

B. User authentication using Network Information Services (NIS).

C. Create local users on the storage system of each video processor in the video production department, and configure permissions to access NFS shares for each local user.

D. Configure the permissions of NFS shares, and only allow workstations in the video production department to access NFS shares.

A. Inherent load balance: the controller is fully active, and the load is evenly shared, improving the utilization of storage resources.

B. Full switching: Use PCIE1.0 full switching interconnection to provide enough switching bandwidth to meet strict performance requirements.

C. Scale-out: Storage resources can be expanded on demand, and performance and capacity can be increased linearly by adding engines.

D. Full redundancy: All components are redundant, and components failover intelligently to meet stringent business continuity requirements.

A. HBA card driver version

B. HBA card concurrent number setting

C. HBA management software version

D. Number of HBA card ports

A. HyperMetro uses the granularity of host I/O to perform concurrent and mutual exclusion on the LBA interval between host I/O accesses and distributed range locks, so as to achieve the purpose of two-way real-time synchronization. This solution can save unnecessary data transmission between arrays.
Auxiliary bandwidth, and effectively reduce the number of data transmissions.

B. HyperMetro optimizes the data transmission between arrays at the protocol level through the FastWrite function, and applies the First Burst Enabled function of the SCSI protocol, which reduces the link transmission intersection of the write data by half.

C. The streamlined copy quickly identifies the source of the data copy through the hardware chip.Find the zero data. During the copying process, for the special identification of all zero data, only a small special page is transmitted to the opposite end, and the full amount is no longer transmitted.

D. In the preferred array mode, when the host service accesses time, the I/O will only be distributed in load balance on the preferred array path set by the user. Arbiter server mode cannot be configured when this mode is configured.
