11 What is the purpose of the Cisco Enterprise Architecture? It replaces the three-layer hierarchical model with a flat network approach.

It provides an enterprise-wide system network architecture that helps protect, optimize, and grow the network infrastructure tha supports the business processes of a company. It provides services and functionality to the core layer by grouping various components into a single component that is located the access layer. It reduces overall network traffic by grouping server farms, the management server, corporate intranet, and e-commerce router the same layer.

12 A network designer must provide a rationale to a customer for a design that will move an enterprise from a flat network topology to a hierarchical network topology. Which two features of the hierarchical design make it the better choice? (Choose two.) reduced cost scalability less equipment required higher availability lower bandwidth requirements 13 A user needs to access a file server that is located in another department. Which layer of the Cisco Hierarchical Network Model will process the traffic first? access core distribution

control 14 What are the responsibilities of devices that are located at the core layer of the hierarchical design model? (Choose two.) access list filtering packet manipulation high-speed backbone switching interconnection of distribution layer devices redundancy between the core devices only 15 Which family of Cisco switches supports Fibre Channel over Ethernet (FCoE)? Catalyst 4948G Catalyst 4500 Catalyst 6500 Nexus 5000
