Which three of the following are globally available Change of Authorization (CoA) options when an endpoint is profiled?

The best choice regarding globally available Change of Authorization (CoA) options when an endpoint is profiled includes "No CoA" as one of the key options.

In the context of CoA, "No CoA" signifies that there is no action taken by the network when a change occurs in the authorization status of the endpoint. It serves as a baseline option, allowing for normal operations to continue without any specific intervention or change in policy enforcement. This is particularly useful in scenarios where a profile does not require immediate action, thus not impacting the network state or the endpoint's connection.

Understanding CoA options requires an awareness of the various actions that can be triggered in response to a change in the condition or context of a device connected to the network. Other options related to CoA, such as port bounce, network scan, and re-authentication, actively modify the connection state or apply a change to the endpoint's authorization level. Each of these actions is more dynamic and can lead to a temporary disruption in service, unlike the "No CoA" option, which maintains the current operational status of the endpoint.
