1.1 LAN DESIGN
5) FAILURE DOMAINS
2) is the area of a network that is impacted when a critical device or network service experiences problems
-
-
4) use redundant links and reliable enterprise-class equipment to minimize the disruption in a network
-
6) in the hierarchical design model, it is usually easier to control the size of a failure domain in the distribution layer
7) in the distribution layer, networks errors can be contained to a smaller area which will impact fewer users
8) when using Layer 3 devices at the distribution layer, every router functions as a gateway for a limited number of access layer users

6) INCREASING BANDWIDTH
1) in a hierarchical network design, some links between access and distribution layer switches may need to process a grater amount of traffic than other links do
2) as multiple links converge into a single link, it is possible for this link to become a bottleneck
3) EtherChannel is a form of link aggregation that will allow the network administrator to increase the amount of bandwidth between devices by creating one logical link out of several physical links
-
5) The EtherChannel configuration takes advantages of load balancing between links that are part of the same EtherChannel
