| Whoever has taken the CCNA exam, please tell me roughly how many input commands did they have? Like: router rip
And also, do you have to type in the access list ones too?
There is a question in Troytec and EE, both have diff answers. Here is the ?
Which statement from a “show spantree 1” command output shows that the Virtual LAN 1 is
functioning?
Troytec: VLAN1 is executing the IEEE compatible Spanning-Tree Protocol.
EE: port Ethernet 0/1 of VLAN is forwarding
Thanks in advance

Thanks in advance! | |

| Also,
Does a bridge INCREASE collison domains or DECREASE the # of collison domains, thanks again

A bridge INCREASES the number of collision domains.
Cheers! | |

| I think Bridges increase collision domains, they give you a situation type question for Access list | |
|
| Ok thanks alot dmaftei and dmaftei!
Azam | |
|
| So, what is the correct answer to the question that is on EE and Tech?
Bridges, Switches and Router breaks up collision domain.
Only Router and VLan breaks up broadcast domain.
A+ MCSE (CCNA next week) | |

| VLANs don't break up broadcast domains. From what I understand, you can configure a switch to breakup a broadcast domain but you normally wouldn't do this. Bridges/Switches do increase the number of collision domains b/c each port on a switch is it's own collision domain, therefore the more ports you have on a switch->the more collision domains you have. | |
|
| Anyone know the answer to this ?
Which statement from a “show spantree 1” command output shows that the Virtual LAN 1 is
functioning?
Thanks in advance

| I'm not positive, but I would go for Troytec: "VLAN1 is executing the IEEE compatible Spanning-Tree Protocol".
As for EE: "port Ethernet 0/1 of VLAN is forwarding"... First, port eth0/1 may belong to different VLAN. Second, it may be in VLAN1, but in a state different than forwarding. I don't think STP in VLAN1 depends on eth0/1 being in forwarding state.

To me it looks like VLANs do break broadcast domains. Consider a Catalyst out of the box. You have 12 or 24 ports in one broadcast domain (by virtue of all ports being in VLAN1). Now you create VLAN2, and asign a couple of ports to it. You end up with two broadcast domains: VLAN1 and VLAN2. Makes sense?

| Thanks Dmaftei, I re-read and it makes sense now.
Each VLAN is it's own broadcast and collision domain, this stops broadcast from hitting the entire internetwork at layer2. That's why switches are such the heat but you still need routers to route between each VLAN.

| now this is productive learning at its best,,,
thanks guys,,,, |
