It's really going to depend on the model and software version of the switch. CDP and STP are both enabled on all switches that I can think of. As for DTP, it depends on the switch. Also, the version of STP running on the switch by default will depend on the model and software version of the switch.
I'll probably leave the question open for another day or so and then mark it answered. I just want to make sure I haven't missed any out.
