FILL BLANK
What LXC command lists containers sorted by their CPU, block I/O or memory consumption? (Specify ONLY the command without any path or parameters.)

正解：

lxc-top
Explanation
LXD supports the following network interface types for containers: macvlan, bridged, physical, sriov, and ovn1. Macvlan creates a virtual interface on the host that is connected to the same network as the parent interface2. Bridged connects the container to a network bridge that acts as a virtual switch3. Physical attaches the container to a physical network interface on the host2. Ipsec and wifi are not valid network interface types for LXD containers. References:
