   An administrator needs to deploy a set of containers that share a common configuration: 2 GB memory, 2 CPUs, and a specific network bridge. However, one container in the set needs a different memory limit of 4 GB. The administrator wants to avoid duplicating the common configuration. What is the best approach?

   • AUse `lxc config set` on each container individually with all the settings.
   • BCreate a base profile with the common settings, apply it to all containers, and override the memory limit on the specific container with `lxc config set`.
   • CCreate a single profile with 4 GB memory and apply it to all containers, then reduce the memory on the others.
   • DCreate two separate profiles, one for the common settings and one for the 4 GB memory, and apply both to the specific container.
