Question
Huawei Cloud's MapReduce service's cloud-native data lake solution provides a leading architecture for storage and computing separation for government scenarios involving massive amounts of unstructured data such as images and videos. It uses cloud-based object storage (OBS) to replace local MRS storage for big data. Which of the following descriptions of the OBS service in this solution is wrong?
Options
- AUse three replicas instead of the EC algorithm to reduce unit capacity cost
- BProvides three types of storage: standard storage, low-access storage, and archive storage
- CExpand capacity on demand
- DDistributed architecture, horizontally scalable
