I've done b and c, but generally prefer:

e) Connect the console port of the switch and other devices to a
terminal server such as a 2511 that is on the network via b or c,
and also has a modem connected to a copper POTS line into which I
can dial if the whole site becomes unreachable from wherever I
happen to be.  Portmaster 2e devices are readily available cheap
and make a good terminal server as well, but they're 3U instead of
the 1U 2511s.  They support 30 lines though.
