Which of the following requirements can be fulfilled by Huawei FusionCompute DRS?

The requirement that can be fulfilled by Huawei FusionCompute DRS relates to the option where specific virtualization constraints must be met. Specifically, the functionality that allows a virtual machine to run on a designated host is critical in scenarios where certain workloads require specific hardware resources or environments. This can be crucial for compliance, performance tuning, or specialized applications that rely on specific host configurations or hardware.

In contrast, other options describe scenarios that FusionCompute DRS does not typically handle. For example, the automatic migration of virtual machines when a host is unavailable is a feature related to high availability and resource balancing, which may involve different technologies or setups within cloud architecture. Other options pertain to management and resource allocation but do not specifically address the requirement of enforcing particular VM placements on set hosts.
