After the master volume of the primary site and the slave volume of the remote slave site establish an asynchronous remote replication relationship, an initial synchronization will be started. After the initial synchronization is completed, the data status of the slave volume becomes complete. Then, which of the following processes are followed to complete the periodic data synchronization? (Multiple choice)
- A . After the write request data is written to the primary volume, the host immediately responds to the write completion
- B . The primary volume receives write requests from the production host
- C . Generate synchronous snapshots of the primary and secondary volumes
- D . When the master volume synchronizes data with the slave volume, the data of the master volume snapshot is read and copied to the slave volume
Huawei’s multipathing software can ensure the redundancy reliability of links between hosts and storage.
Which of the following does not belong to the load balancing algorithm of the multipathing software? (Multiple choice)
- A . Maximum Task Algorithm
- B . Minimum Queue Depth Algorithm
- C . Polling Algorithm
- D . Maximum Path First Algorithm
When delivering the flash storage project, Huawei engineers focused on introducing the multi-tenancy feature of flash storage to customers. This feature can achieve business data isolation. Although different tenants cannot access each other’s LUN, they can access each other’s file system.
- A . True
- B . False
In Erasurecode technology, if the data protection level is set to 4+2, the corresponding metadata will generate 3 identical images.
- A . True
- B . False
Huawei flash storage can support HyperReplication remote replication feature, which is mainly used in data disaster recovery and backup scenarios.
Which of the following concepts related to this feature are correct? (Multiple choice)
- A . Pair refers to the data replication relationship between the primary LUN and the secondary LUN. When the Pair operation status is "normal", the data of the primary LUN and the secondary LUN are successfully synchronized.
- B . Slave resource protection refers to the process of suspending the remote replication relationship between the primary volume and the secondary volume.
- C . A consistency group is a collection of pairs associated with multiple services.
- D . Synchronization is the process of copying data from the primary volume to the secondary volume.
A financial customer purchased several Huawei flash storages for business deployment. To ensure business continuity, engineers configured the Hyperiletro feature on the storage.
If an engineer wants to remove a LUN through the CLI, which of the following commands can be used to do so? (Multiple choice)
- A . remove protect Group lun
- B . remove lun group Lun
- C . remove hyper Metro_consistency_group pair
- D . show protect Group general
Daily management of Huawei flash storage systems involves power-on and power-off operations.
Which of the following descriptions about powering on and off the storage system is wrong?
- A . For Huawei OceanStor Dorado6800 storage, when the controller enclosure is powered on, the disk enclosures cascaded to it will automatically power on.
- B . To power on the storage system again after an emergency power off, follow the steps to power on the storage system. That is, press the power button on the controller.
- C . When all controller boxes in the cluster are powered off, you can log in to the BMC system through the BMC external management IP and execute the power-on command to power on all controller boxes in the cluster.
- D . Before powering on the storage system, ensure that all cascading cables are correctly connected. If the cascading cable connection method is adjusted after powering on, the storage system may malfunction.
Huawei’s OceanStorPacific series storage is an intelligent distributed storage product that can be horizontally expanded on a large scale and has high reliability.
Which of the following descriptions about the reliability of this product are wrong? (Multiple choice)
- A . The system uses link aggregation-based technology to achieve transmission link redundancy and performs link switching (or isolation) when a link fails or is sub-healthy, thereby ensuring business continuity.
- B . Data reliability: Based on the traditional hard disk-level RAID mode, it supports multiple RAID strategies
- C . Multiple copies can be used to implement RAID functions within nodes. When a node fails, the system reliability is not degraded, and is even higher than the EC mechanism.
- D . Based on Kunpeng processor, it can integrate multi-chip functions to achieve single-chip integration, effectively improving hardware reliability
A government customer purchased several Huawei flash storages for business deployment. The administrator configured the SmartVirtualization heterogeneous virtualization feature on the storage.
Which of the following descriptions of this feature are wrong? (Multiple choice)
- A . After the administrator configures this feature, when the application server sends a request to read data from an external LUN, the eDevLUN of the local storage system receives the data read request and reads the data from the external LUN of the heterogeneous storage system.
- B . When the administrator configures offline takeover of a third-party heterogeneous storage system, there is no need to first establish a logical connection between the local storage system and the heterogeneous storage system.
- C . When the heterogeneous storage is a third-party storage system, the local storage system needs a license file to authorize its use
- D . When the heterogeneous storage system is a Huawei storage system (excluding OE storage systems), the heterogeneous storage system needs to obtain a license to use the SmartVirtualization feature.
Huawel OceanStor Pacific series products provide object storage capabilities and support cross-site disaster recovery (DR).
Which of the following statements about object storage cross-site DR is false?
- A . In cross-site DR cluster deployment mode, each site is independent. Specifically, it has an independent DeviceManager GUI and independent erasure code (EC) configuration.
- B . In backup and archiving scenarios that do not require a low latency, the redundancy mode between sites can be set to EC redundancy during cross site DR configuration.
- C . During cross-site DR configuration, if replicas are used for redundancy protection across sites, each site has complete object data.
- D . The cross-site DR of OceanStor Pacific series uses an asynchronous replication mechanism. The recovery point objective (RPO) is greater than 0, and the traffic control configuration cannot be adjusted.
