e. All of the above
B
Why are networks designed with layers?
a. Allows focus within specific layers due to grouping, segmentation, and compartmentalization
b. Simplification of network design
c. Optimizes use of physical interconnects (links)
d. Optimizes applications of policies and access control
e. Eases network management
f. All of the above
B

a. Core
b. Access
c. Distribution
d. Enterprise edge
e. WAN
f. Wireless
A,B,C,D
What is another common name for the core layer?
a. Backbone

c. Data Center
d. Routing layer
B
In newer technology, what layers are referred to as the spine layer and the leaf layer?
a. The spine layer is the equivalent of the of the core layer, and the leaf is equivalent to the to the distribution layer.
b. The spine layer is equivalent to the access layer, and the leaf layer is equivalent to the distribution layer.
c. The spine layer is equivalent to the distribution layer, and the leaf layer is equivalent to the access layer.
d. The spine layer is equivalent to the core layer, and the leaf layer is equivalent to the access layer.
B
Match each layer to its definition.
