The department currently has only ten users, but plans to double the number of users within the next six months. The engineers need to access CAD documents on the workgroup servers. What is the most appropriate device at the access layer of Cisco's Hierarchical Network Design Model?

a) Catalyst 1900 series switch with 100BaseTX ports
b) Catalyst 2900 series switch with 100BaseTX ports
c) Catalyst 5500 series switch
d) Catalyst 8500 series switch

Answer
a) Catalyst 1900 series switch with 100BaseTX ports

Explanation
For a small number of users at the access layer, the most appropriate, cost-effective device is the Catalyst 1900 series switch with 100BaseTX ports. Any of the other listed devices would be overkill and a waste of money. The Catalyst 5500 series switch is most appropriate for use in the distribution layer. The Catalyst 8500 series switch is most appropriate for use in the core layer.

(Choose 2)

a) Core layer
b) Physical layer
c) Access layer
d) Network layer
e) Distribution layer

Answer
b) Physical layer
d) Network layer

Explanation
The layers of Cisco's Hierarchical Network Design Model are the core, distribution and access layers. The network and physical layers exist in the OSI reference model.
