What are Huawei's cloud computing disaster recovery backup solutions? (Multiple choice)

Huawei provides a comprehensive suite of cloud computing disaster recovery (DR) and backup solutions covering various protection levels. The options, despite containing apparent typos in product names, represent the core capabilities of Huawei's portfolio. This includes: backup services (represented by 'HypErDP'), host-based replication for granular VM protection, storage-based replication for high-performance data protection (both managed by solutions like UltraVR), and active-active DR for business continuity with zero data loss (like HyperMetro). All four options describe valid DR and backup strategies offered by Huawei.

There are no incorrect options. Each choice represents a distinct and valid category of disaster recovery or backup solution available within the Huawei technology ecosystem, even if the specific acronyms provided in the question are imprecise.
