Regarding security groups in Huawei Fusion Compute, which statement is true?

In Huawei FusionCompute, a network card is indeed limited to being assigned to only one security group at a time. This design ensures that the configuration and rules associated with that security group directly govern the traffic flow and network access for that specific network card.

By confining a network card to a single security group, it simplifies the management of security policies and reduces the risk of conflicting rules that may arise from multiple security group assignments. This approach also offers clarity in monitoring and managing the network traffic associated with that network card, ensuring that all security measures are straightforward and properly enforced.

The other statements incorrectly reflect how security groups function within the Huawei FusionCompute environment. For instance, claiming that a network card can belong to multiple security groups would introduce complexity that could lead to conflicting security policies, which is not the case in this system. Similarly, the assertion that security groups do not filter traffic or that network cards do not utilize security groups misrepresents the core functionality of security groups, which is to regulate and control access to network resources effectively.
