If NUMA topology is set, CPU topology is still needed?

For example, I want to VM to run on one of the host NUMA nodes with four dedicated CPUs, it's enough with following commands?

openstack flavor set FLAVOR-NAME --property hw:numa_nodes=1 --property hw:numa_cpus.0=4 --property hw:cpu_policy=dedicated
