Huawei HCIE-Storage V3.0 - H13-629_V3.0 模擬練習
Huawei geo-redundant 3DC DR solution ensures the continuity of core services even if any two data centers are damaged. The geo-redundant 3DC DR solution (synchronous remote replication+asynchronous remote replication) is used as an example. The solution architecture has four layers. Associate the functions with the layers.
正解:
Explanation:
DR data replication # Storage layer; Service access link # Network layer; Service system operating platform # Host layer; DR policy formulation # DR management layer Huawei ' s DR technology section identifies replication at the host layer, SAN network layer, and storage array layer. It states that storage-layer DR uses inter-array data replication to replicate data from the local array to the DR array. Network-layer DR places the replication mechanism between application servers and backend storage. For the host layer, the course states that data-replication or switchover software can be installed on hosts in the production and DR centers to form an application-level DR solution. The DR- management function is provided by BCManager/eReplication. Its server performs "DR service process control, DR policy scheduling, and configuration data management of DR resources and services." Therefore, replication of protected data belongs to the storage layer; connectivity between sites and services belongs to the network layer; the service operating environment belongs to the host layer; and formulation/orchestration of DR policies belongs to the DR-management layer.

The OceanStor Pacific series scale-out storage system consists of multiple node roles. The ___ component must be deployed on management nodes, compute nodes, and storage nodes for the system to run properly.
(Enter an abbreviation.)
(Enter an abbreviation.)
正解:
MDC
Explanation:
The required component is MDC.
OceanStor Pacific uses a distributed control architecture in which cluster-management and metadata/control services must remain highly available as nodes are added, removed, or experience failures. Huawei specifically identifies multi-MDC as a mechanism that improves system reliability. The training architecture also shows MDC participating in sub-health management together with storage-side processes such as OSD and EDS.
This distributed deployment is consistent with the architecture of OceanStor Pacific: storage services are spread across nodes, and control information must remain accessible regardless of the physical node role. The system therefore cannot depend on one isolated control instance.
Huawei also describes OceanStor Pacific as a three-layer scale-out architecture integrating block, file, object, and HDFS services, with cluster-status control, distributed data routing, redundancy management, rebuilding, and balancing forming core storage-engine functions. MDC supports the distributed coordination and control required by this architecture.
The supplied question set identifies MDC as the required abbreviation.
