What network design would contain the scope of disruptions on a network should a failure occur?
- the installation of only enterprise class equipment throughout the network
- the configuration of all access layer devices to share a single gateway
- the reduction in the number of redundant devices and connections in the network core
- the deployment of distribution layer switches in pairs and the division of access layer switch connections between them
| Answers Explanation & Hints:
One way to contain the impact of a failure on the network is to implement redundancy. One way this is accomplished is by deploying redundant distribution layer switches and dividing the access layer switch connections between the redundant distribution layer switches. This creates what is called a switch block. Failures in a switch block are contained to that block and do not bring down the whole network. |
