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!
I’m so confused.
I think the answer is the second option, but honestly, i am not sure about it. I hope if anyone can give me feedback on my answer.
I am sorry to say that Eleanor, but it is the wrong answer.
Anyhow, “the deployment of distribution layer switches in pairs and the division of access layer switch connections between them” is the right answer to this question.
Thank you Eleanor for your time and help!
I am confused too, I feel that the CCNA questions are almost confused ones, and that makes me frustrated. Also, I feel that this is an important topic to understand well.
I hope anyone can provide us with the right answer as well as an explanation for it.
As Gianna mentioned, the fourth option is the right answer, and this is the explanation for it: One way to mitigate the impact of network outages is to implement redundancy. One way to do this is to deploy redundant distribution switches and split the access layer switch connections between the redundant distribution switches, and this will create a so-called switch block. Errors in a switch block are limited to that block and do not bring down the entire network.
