NEW QUESTION # 31
What architecture is adopted for HyperMetro data centers using OceanStor Dorado?
Answer: A
Explanation:
OceanStor Dorado HyperMetro adopts a gateway-free active-active architecture. In this design, two storage systems at different sites both provide read and write services to hosts at the same time.
Because there is no external virtualization gateway in the data path, the architecture avoids extra latency, additional failure points, and gateway performance bottlenecks. Hosts can access the same logical storage resources through both sites, and quorum mechanisms help determine the surviving site if a fault occurs. This design supports high availability, load balancing, and zero service interruption for mission-critical applications when properly deployed with multipathing and redundancy. Gateway- based designs depend on additional virtualization appliances, while active-passive designs do not allow both sites to provide services simultaneously. Therefore, the correct architecture is gateway-free active- active.
NEW QUESTION # 32
Source deduplication reduces the amount of data to be transmitted, saves network bandwidth, and transmits non-duplicate data, improving logical backup bandwidth and shortening backup time.
Answer: A
Explanation:
Huawei OceanProtect utilizes source deduplication to optimize the data protection process. In traditional backup scenarios, the entire dataset is sent over the network to the backup target, which can consume significant bandwidth and time. With source deduplication, the storage system or backup agent identifies redundant data blocks at the source-before they are sent over the network.
By comparing new data chunks against a local cache of already-transmitted fingerprints, the system ensures that only unique, non-duplicate data is physically moved across the production-to-backup link. This significantly reduces network bandwidth consumption and effectively increases the logical backup bandwidth, as the system can process larger volumes of data without being limited by physical network throughput. Consequently, the backup window is shortened, allowing organizations to meet tight RPOs even in environments with limited network resources or massive data growth.
NEW QUESTION # 33
In SmartMulti-Tenant, a vStore is managed by only one tenant administrator, and vStDres are isolated from each other.
Answer: A
NEW QUESTION # 34
To support the NAS active-active function, the new-gen hybrid flash storage requires a NAS gateway.
Answer: A
Explanation:
This statement is false because Huawei ' s new-generation OceanStor hybrid flash storage features a converged (Unified) architecture that supports Native NAS capabilities directly within the storage controllers.
In older storage generations or with competitors, an external " NAS Gateway " or " Filer " was often required to provide file services on top of block storage.
Huawei's HyperMetro for NAS is a gateway-free active-active solution. The file systems are managed natively by the storage OS (OceanStor OS), allowing both SAN and NAS services to benefit from the same high-availability features. By eliminating the need for an external gateway, Huawei simplifies the network topology, reduces hardware costs (TCO), and minimizes latency by removing an extra processing hop for file data. This native integration allows for seamless cross-site active-active deployments for file protocols like CIFS/SMB and NFS, just as it does for block protocols.
