H19-308_V4.0 Practice Questions

In Huawei’s object storage management (OceanStor Pacific), quotas are a critical administrative tool for resource governance. Option C is correct as quotas serve as a fundamental method for controlling how much of the physical resource pool a specific entity (tenant or user) can access and consume.

Option A and D are correct because Huawei supports both Tenant-level and Bucket-level quotas. Once a Hard Quota limit is reached for a tenant or a specific bucket, the storage system will reject further write requests (PUT operations) to prevent exceeding the allocated budget. Option B is correct because the storage management system (DeviceManager or eSight) integrates with the quota system to trigger alarms when usage reaches predefined thresholds (such as 80% or 90%) or when the resource limit is reached, allowing administrators to take proactive measures like expanding the quota or cleaning up data.

Huawei’s new-generation OceanStor hybrid flash storage systems (such as the 5000 and 6000 series) provide high-density snapshot capabilities to ensure data resilience against logical errors or malicious attacks. According to the technical specifications for these systems, the minimum intervals for secure snapshots differ between file and block services.

For SAN (Block) storage , the system can support high-frequency snapshots with a minimum interval of 3 seconds . This low interval allows for near-continuous data protection, enabling recovery points that are extremely close to the moment of a failure or attack. For NAS (File) storage , the minimum secure snapshot interval is 15 seconds . While slightly longer than the SAN interval, this still provides superior granularity for file-level recovery compared to traditional backup schedules that often run only once per day or hour. These " HyperSnap " and " HyperCDP " features ensure that mission-critical applications can be rolled back to a healthy state within seconds, significantly reducing the Recovery Point Objective (RPO) for both structured and unstructured data.

The new-gen Huawei OceanStor hybrid flash storage is a unified enterprise storage platform, so it supports multiple workload and service types. Block services are used for databases, virtualization, and other applications that require LUN-based access through SAN protocols. File services are used for NAS workloads through protocols such as NFS and SMB/CIFS. VM services are supported because the platform integrates with virtualization environments and provides shared storage for virtual machines. Container services are also supported through modern container storage integration, enabling persistent storage for cloud-native applications. This broad service support is important because enterprises increasingly want one platform to support traditional applications, virtualized workloads, and containerized applications. Therefore, all listed service types are supported by the new-gen OceanStor hybrid flash storage.
