I am trying to solve some CCNA practice questions, I am stuck on this question:
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
Please, if anyone can help me with it! Thank you in advance!
