The tricky part of the question--and I think someone touched on this
before--is that a managed switch is going to have an ARP table and a CAM
table, and they're completely different animals.
The ARP table is used only when the switch itself is communicating with
other IP devices. It will send an ARP request and place any responses
in the ARP table. The key is this: the ARP table matches an IP
address to a MAC address.
The CAM (Content Addressable Memory, IIRC) table is what correlates
destination switch ports with MAC addresses. If the switch receives a
frame from a device, it places that device's MAC address and incoming
port # into the CAM table. The key: the CAM table associates MAC
addresses with switch ports.

The question is simple, but sonds tricky :o) Yes- every connected MAC,
be
it the Hub or addresses passing through the hub from say workstations.
