Huawei HCSA-Presales-Storage V4.0 Sample Questions (Q65-Q70):

NEW QUESTION # 65
RAID 0 is actually a mirroring technology.

Answer: A

Explanation:
This statement is false because RAID 0 and Mirroring (RAID 1) are fundamentally different concepts in Huawei storage technology. As defined in the Huawei technical manual, RAID 0 is " Striping. " It breaks data into chunks and spreads them across multiple disks to increase performance. It has no redundancy.
" Mirroring " is the terminology specifically used for RAID 1. In a RAID 1 configuration, the system writes the exact same data to two separate physical disks simultaneously. This creates a 100% redundant copy (a mirror). If one disk fails, the other continues to provide data, ensuring zero downtime and no data loss.
Huawei ' s RAID 2.0+ virtualization technology can implement striping and mirroring across different " chunks " or " extents " within a storage pool, but it maintains the technical distinction: RAID 0 is for performance through striping, while mirroring is for reliability through duplication. Therefore, characterizing RAID 0 as a mirroring technology is a technical inaccuracy.


NEW QUESTION # 66
Which container plug-ins are supported by the new-gen OceanStor hybrid flash storage? (Select all that apply)

Answer: B,D

Explanation:
The new-generation OceanStor hybrid flash storage is designed to support modern cloud-native workloads, including those running in containerized environments. To facilitate the connection between storage resources and container orchestrators like Kubernetes, Huawei supports several key plug-ins:
CSI (Container Storage Interface) (Option D): This is the industry-standard interface that allows the storage system to provide persistent volumes (PVs) to containers. By using the Huawei CSI plug-in, users can automate the provisioning, mounting, and management of LUNs (SAN) and File Systems (NAS) directly from Kubernetes manifests.
CDR (Container Disaster Recovery) (Option A): In addition to basic connectivity, Huawei provides the CDR plug-in to manage data protection for containerized applications. CDR enables backup and disaster recovery capabilities for persistent data, ensuring that if a container cluster or a data center fails, the application data can be recovered at a secondary site using replication or backup technologies.
Plug-ins like CSS or ECS (Options B and C) are generally related to other cloud services or specific compute instances and are not the primary container storage plug-ins associated with the OceanStor hybrid flash series.


NEW QUESTION # 67
Which are advantages of SAN storage?

Answer: A,B,C,D

Explanation:
SAN storage provides several major advantages over direct-attached storage. High resource utilization is achieved because multiple servers can share centralized storage resources instead of leaving capacity stranded on individual servers. High scalability is another advantage because capacity and performance can be expanded by adding disks, controllers, paths, or storage arrays without redesigning each host individually. High reliability comes from enterprise storage features such as redundant controllers, multipathing, RAID protection, hot-swappable components, and mature failover mechanisms. SAN also provides high performance because it delivers block-level access through dedicated storage networks such as Fibre Channel, iSCSI, or InfiniBand. This makes SAN especially suitable for databases, virtualization platforms, and mission-critical enterprise applications. Therefore, all four listed options are valid advantages of SAN storage.


NEW QUESTION # 68
