I feel like it could be either Keepalive or Echo, but I lean towards Keepalive since it sounds more like a periodic check.

I remember practicing a similar question, and I think Echo packets were mentioned in that context, but I can't recall if they were specifically for link status.

I think the AP sends Keepalive packets to check the link status, but I'm not entirely sure if that's the right term.
