And now.. the answers!

1. (B). Works like a charm - if your end users are having trouble getting their IP addresses via DHCP in a timely manner, try running Portfast on their switch ports.

 

2. (A). When you enable Uplinkfast on a Cisco switch, its priority will be set to 49,152.

 

3. (D). Uplinkfast should be run only on your access-layer switches, and actually can't be run on a root switch.

 

4. (A). For best result, enable Backbonefast on all switches.
