Network Design Model Quiz

What is the primary role of the Access layer in the three-layer hierarchy network design model?

• To provide fast transport between distribution switches

• To provide network access for workgroups and users

• To control the flow of data between different parts of the network

• To connect distribution layers with fiber links

Which layer in the three-layer hierarchy network design model is responsible for controlling the boundary between the access and core layers?

• Access layer

• Distribution layer

• Core layer

• None of the above

What is the function of the Core layer in the three-layer hierarchy network design model?

• To ensure data can zip around the network as quickly as possible

• To provide network access for workgroups and users

• To control the flow of data between different parts of the network

• To provide power to devices that need it

According to the text, what is a benefit of using a fiber link in the Distribution layer?

• It provides power to devices like IP phones

• It offers faster data transport and better distance

• It controls the boundary between the access and core layers

• It ensures only authorized devices can connect to the network

What happens at the Distribution layer regarding routing, as mentioned in the text?

• Routing happens at the access layer

• Routing happens at the core layer

• Routing happens at the distribution layer

• No routing happens at any layer

What is the purpose of the hierarchy principle in network design according to the structured engineering principles?

• To separate the network into physical layers

• To divide the complex problem of network design into smaller and easier to manage areas

• To increase the network's resistance to failures

• To ensure that all devices come with two NICs cards

Which layer in the 3-layer hierarchy network design is described as the simplest but most critical, consisting of high speed network devices?

• A) Access layer

• B) Distribution layer

• C) Core layer

• D) Service layer

According to the text, why is there typically no need for redundancy in the access layer?

• A) End devices usually come with multiple NICs cards

• B) It is less expensive and takes up less space

• C) The access layer is not critical to network function

• D) Redundancy is managed at the core layer instead

What is a key reason for needing redundancy at the core layer of a network?

• A) The core layer has all of the distribution layers connected to it

• B) The core layer is less expensive to manage

• C) The core layer devices come with two NICs cards

• D) The core layer is not as critical as the access layer

What is the purpose of using fiber uplinks in network devices?

• To reduce the number of devices required

• To ensure high-speed ethernet links

• To connect multiple devices using a star topology

• To decrease bandwidth and increase distance
