Section 1.2: 3550 LAN Switch Configuration
Q: Do I have to configure the switch as a VTP server?
A: The questions do not ask you to do this and there is only one switch in the network.
Q: Why can't I rename VLAN1?
A: You can't so don't waste time on this.
Q: Can I leave my switch ports in auto mode?
A: The questions do not specifically ask you to configure speed and duplex, but you should do this to avoid any mismatches that could cause you problems.
Q: For the future port 0/16, can I leave it in VLAN1?
A: There is no specific VLAN stated in the question, so yes.
