   ** CPU Processors: To run specific Telco workloads, the CPU Processor model should be adapted to enable most of the features available in this reference <<atip-features,table>>.

-When `cilium` is set as default/primary CNI plug-in, following TCP port is additionally exposed when the cilium-operator workload is configured to expose metrics outside the Kubernetes cluster on which it is deployed. This ensures that an external `Prometheus` server instance running outside that Kubernetes cluster can still collect these metrics.
