Latest Huawei H19-110_V2.0 Practice Test Questions, HCSA-Sales-Storage V2.0 Exam Dumps [Q19-Q37]

Explanation
The reason why backup storage capacity is larger than production storage is not that backup storage stores multiple copies of production data, but that backup storage stores multipleversions of production data. Backup storage provides data protection for production data by creating backup images at different points in time.
These backup images can be used to restore production data in case of any data loss or corruption. Backup storage usually stores more versions of production data than production storage itself, which makes backup storage capacity larger than production storage capacity.

Explanation
The highlight of OceanStor Dorado HyperMetro solution is that Huawei HyperMetro can support active-active SAN&NAS solution without adding any hardware or licenses. HyperMetro is a gateway-free active-active solution that synchronizes data between two storage systems in real time and ensures zero service interruption and zero data loss in case of any failure in one system or site. HyperMetro also supports transparent failover and load balancing, which enhances the performance and efficiency of data storage. HyperMetro can support both SAN and NAS protocols in one box, which means it can provide active-active protection for both block and file services without requiring separate devices or gateways.

Explanation
The advantages of Huawei OceanProtect over traditional backup storage are rapid backup, rapid recovery, high reliability, and efficient reduction. OceanProtect can provide fast backup and recovery performance by using front-end network optimization, CPU computing optimization, back-end network optimization, and intelligent scheduling technologies. OceanProtect can also ensure high reliability by using RAID-TP technology that can tolerate the simultaneous failures of three disks in a RAID group. Moreover, OceanProtect can achieve high data reduction ratio by using deduplication and compression technologies that can reduce the backup data size by up to 90%.

Explanation
OceanStor Pacific does not adopt a full symmetric architecture. OceanStor Pacific adopts a distributed architecture that consists of multiple nodes that are interconnected by a network. Each node has its own storage resources and computing resources, and can provide data services independently or collaboratively.
The distributed architecture provides high performance, scalability, reliability, and efficiency for unstructured data storage.

Explanation

Explanation
OceanProtect Backup Storage is compatible with Veeam, Veritas, and Commvault. These are some of the mainstream backup software in the industry that can work with OceanProtect toprovide comprehensive data protection for enterprise data. OceanProtect supports multiple backup protocols, such as NDMP, VTL, and NAS, and can seamlessly integrate with these backup software to provide fast backup and recovery services.

Explanation
All-flash storage can contribute to carbon neutrality by reducing the energy consumption and carbon footprint of data centers. Compared with mechanical disks, fewer SSDs can provide the same or higher performance and capacity, while saving more energy. According to a report by DEKRA9, taking a data center with 1000 disks as an example, replacing mechanical disks with SSDs reduces power consumption by 2.4 times and carbon emissions by 2.3 times per year1

Explanation
OceanStor Dorado can support multiple sales scenarios, such as databases, virtualization, and High-Performance Data Analytics (HPDA). OceanStor Dorado can provide low latency, high throughput, and high IOPS for database applications, such as Oracle, SAP HANA, and MySQL. OceanStor Dorado can also optimize the performance and efficiency of virtualization environments, such as VMware, Hyper-V, and OpenStack. Moreover, OceanStor Dorado can accelerate the data processing and analysis of HPDA applications, such as EDA, AI, and big data.

Explanation
In Huawei E2E anti-ransomware solution from production storage, to backup storage and to DR storage, the products are OceanStor Dorado, OceanStor Pacific, and OceanProtect. OceanStor Dorado is the production storage that provides high performance and reliability for critical applications. OceanStor Pacific is the backup storage that provides efficient data reduction and protection for large-scale data. OceanProtect is the DR storage that provides fast backup and recovery for disaster scenarios .

Explanation
Dorado can provide secure snapshot as an anti-ransomware function. Secure snapshot is a feature that allows users to create read-only copies of data at a specific point in time. Secure snapshots are protected from deletion or modification by ransomware or unauthorized users. Secure snapshots can also be used to quickly restore data to a previous state in case of ransomware attacks .

Explanation
Backup storage is a type of data storage that is used to create copies of data that can be restored in case of data loss, corruption, or disaster. Backup storage typically has high performance and reliability, and often uses incremental or differential methods to reduce the amount of data that needs to be backed up. Backup storage can be located on-premises or in the cloud

Explanation
OceanProtect has high data reduction ratio because it uses advanced deduplication and compression technologies to eliminate redundant data and save storage space. This reduces the backup storage space required and lowers the total cost of ownership (TCO) for customers. Reference: [OceanProtect Backup Storage Product Brochure]
