Correct Answer: B
Question 77
Which of the following replication modes are supported by remote replication? (Select all that apply)
Correct Answer: A,C
Huawei's HyperReplication technology is designed to provide robust data redundancy across geographically separated storage systems. According to official technical specifications, Huawei storage supports two primary replication modes: Synchronous Remote Replication (Option A): In this mode, data is written to both the local and remote storage systems simultaneously. The host receives a write-completion acknowledgement only after the data is successfully stored in both locations. This ensures zero data loss (RPO = 0) but is sensitive to network latency and is typically limited to distances within 100km to 300km. Asynchronous Remote Replication (Option C): Data is first written to the local storage, and the host receives an immediate acknowledgement. The data is then synchronized to the remote site at defined intervals or based on specific triggers. This mode is not limited by distance and has minimal impact on application performance, though it carries a risk of minor data loss (RPO > 0). Terms like "Semi-synchronous" or "Semi-asynchronous" (Options B and D) are not standard replication modes in the Huawei OceanStor architectural framework.
Question 78
Does OceanStor F V5 support 3.5-inch SSDs?
Correct Answer: B
Question 79
What are the characteristics of DAS? (Select all that apply)
Correct Answer: A,B,C
Direct-Attached Storage (DAS) is a traditional storage architecture where storage devices are connected directly to a host server. Huawei documentation defines the following key characteristics: Direct Connection (Option C): DAS connects to the server via internal or external interfaces such as SATA, SAS, or SCSI, rather than through a storage network. No Network Devices (Option A): Because it is a 1-to-1 connection, it does not require Fibre Channel switches or Ethernet switches to facilitate the link between the host and the storage. This makes it simple and cost-effective for small-scale deployments. Block Storage Services (Option B): Like a SAN, DAS provides block-level access. The server's operating system manages the file system (NTFS, EXT4, etc.) directly on the provided blocks. While a server attached to DAS can share its files over a network (becoming a file server), the DAS itself is not a "File Storage Service" (Option D). In Huawei's hierarchy, file services are the domain of NAS (Network Attached Storage), which provides shared access to files via protocols like CIFS/SMB or NFS.
