In Huawei FusionCompute, what is stated incorrectly about port groups and security groups?

The choice regarding port groups being a "collection of rules" is incorrectly stated. In Huawei FusionCompute, a port group is actually a category that contains virtual ports and associates them with specific networking configurations for virtual machines. It primarily relates to the organization and management of virtual network interfaces, rather than serving as a collection of rules.

On the other hand, a virtual machine's Network Interface Card (NIC) connects to a virtual port within a port group, establishing the connection necessary for network communication. Furthermore, a Distributed Virtual Switch (DVS) can indeed have multiple port groups, which helps in managing various networking configurations suited for different types of workloads or applications. Security groups, as stated, are indeed used to protect virtual machines by defining security rules that dictate allowed and denied traffic, enhancing the overall security posture of the virtualized environment. This helps to better manage access and mitigate unauthorized connections to virtual machines.
