What statement accurately describes the relationship between port groups and security groups in Huawei FusionCompute?

A VM (Virtual Machine) NIC (Network Interface Card) can indeed be directly connected to a port group in Huawei FusionCompute, which emphasizes the practical role that port groups play in networking management within the virtualization environment.

In the context of Huawei FusionCompute, port groups serve as a means to group multiple virtual ports, simplifying network configuration and management for virtual machines. Each virtual machine can have one or more NICs that are configured to connect to these port groups, allowing for tailored network connectivity and enhanced traffic management. This direct connection facilitates easier administration of networking settings applied to all VMs associated with the same port group, ensuring that they share consistent configurations without needing to set parameters for each VM individually.

The other statements do not correctly reflect how port groups and security groups function within Huawei FusionCompute. Port groups do interact with security controls, rather than functioning entirely independently. Additionally, security groups can contain multiple port groups, which contradicts the notion that they can only contain one. Rules and configuration settings are crucial in a virtual environment to ensure proper security and operational functionality, making the last statement incorrect as well.
