Hierarchical network design question?

| A network administrator needs to increase bandwidth and reduce traffic on a network. What should be used in the access hierarchical network design model to dedicate bandwidth to users while limiting broadcast domains?
1. one router with multiple fast Ethernet interfaces
2. multiple routers with Fast Ethernet interfaces
3. multiport gigabit switches
4. switches running VLANS
5. managed smart hubs. | |

what do you think it is and why? | |

Reduce traffic, increase bandwidth, limiting broadcast domains. This is our goal to implement at the access layer.
1. one router with multiple fast Ethernet interfaces
This won't help us at the access layer
2. multiple routers with Fast Ethernet interfaces
Again, not for the access layer
3. multiport gigabit switches
Well, hot damn this sound fun...but doesn't do anything for broadcast domains.
4. switches running VLANS
This is the only answer that satisifys all requirements. Each port is a separate colision domain and each vlan is its own broadcast domain.
5. managed smart hubs.
This does nothing for broadcast domains, not sure about colision domains as I'm not sure how a managed smart hub differs from a standard layer 1 hub.
But here's what I have on the access layer that, if known, would make this a very simple question.
From the cisco press ccnp switching (642-811, bcmsn) book quote:
Access Layer:
The access layer is present where the end users are connected to the network. Devices in the layer, sometimes called building access switches, should have the following capabilities:
* Low cost per switch port
* High port density
* Scalable uplinks to higher layers
* User access functions such as VLAN membership, traffic and protocol filtering and QoS
* Resiliency through multiple uplinks
Much more indepth info can be found on cisco.com | |

| That is the exact answer that I found from the Cisco book. I have another question. Which of the following services are provided by enterprise servers? DNS and E-Mail I know are correct but I need one more from these choices user applications, file sharing, print sharing, corporate intranet? Also one more question Which of the following are characteristics of the core layer of the hierarchical network design model? Redundant Pathc, Rapid Forwarding traffic and no packet filtering are what I choose. There are 3 other choices left and I think the ones I chose are correct the remaining choices are high-level policy enforcement, packet manipulation which I read that it does not provide, and media transitions. Thanks alot for the help I greatly appreciate it. | |

| I found it corporate intranet and redundant path. Thanks for your help. |
