質問 # 19
Why bakcup storage capacity is larger than production storage is that backup storage stores multiple copies of production data...
- A. False
- B. True
正解：A
解説：
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.

質問 # 21
How can storage contribute to carbon neutrality?
- A. All-flash storage is easier to maintain.
- B. All-flash storage has become the norm. Compared with mechanical disks, fewer SSDs can save more energy. Taking a data center with .. SSDs reduces power consumption by 2.4 times.
- C. All-flash storage is easier to use.
- D. All-flash storage is more reliable.
正解：B
解説：
Explanation
All-flash storage can contribute to carbon neutrality by reducing the energy consumption and carbon footprint of data centers.

質問 # 27
The main benefit of OceanStor Pacific multi-protocol interworking feature is reducing the footprint of hardware.
- A. False
- B. True
正解：A
解説：
Explanation
The main benefit of OceanStor Pacific multi-protocol lossless interworking feature is not reducing the footprint of hardware, but eliminating the need for data copy among different systems. OceanStor Pacific has a multi-protocol lossless interworking feature that allows one copy of data to be shared with multiple services using different protocols such as NFS, SMB, S3, or HDFS. This feature avoids data copy among different systems, which improves the efficiency and performance of data access and analysis. It also simplifies the management and reduces the complexity of the system. Reducing the footprint of hardware is a secondary benefit of this feature, as it lowers the total cost of ownership (TCO) with less hardware investment, power consumption, and maintenance costs.

質問 # 34
OceanStor Dorado can support multiple types of 3DC solution, which of following 3DC topologies can be supported by Dorado.
- A. Serial
- B. Star
- C. Parallel
正解：A、B、C
解説：
Explanation
OceanStor Dorado can support multiple types of 3DC solution, which is the core of the Geo-Redundant Solution that ensures service continuity and data reliability in case of disasters. The 3DC solution consists of a production center, an intra-city DR center, and a remote DR center. The supported 3DC topologies are parallel, serial, and star. In parallel topology, both the production center and the intra-city DR center form remote replication relationships with the remote DR center. In serial topology, the production center forms a remote replication relationship with the intra-city DR center, which in turn forms another remote replication relationship with the remote DR center. In star topology, the production center forms a HyperMetro relationship with the intra-city DR center, and both of them form remote replication relationships with the remote DR center.
