Catalyst 4503 switches Cisco 5500 security appliance firewall Catalyst 6509 switches lightweight access points Catalyst 2960 switches What two traffic types must be included when calculating the bandwidth requirements to support a voice stream in an IP telephony network? (Choose two.) voice queues voice carrier stream voice services traffic call control signaling routing updates What are three properties of peer-to-peer applications? (Choose three.) require dedicated bandwidth allocation can be used in video conference applications require real-time interaction between peer devices can be used to fulfill the requirements for IP phone calls require a direct physical connection between devices require centralized authentication What are the responsibilities of devices that are located at the core layer of the hierarchical design model?

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 During an evaluation of the currently installed network, the IT staff performs a gap analysis to determine whether the existing network infrastructure can support certain new features. At which stage of the Cisco Lifecycle Services approach does this activity occur? prepare phase plan phase design phase implement phase operate phase optimize phase Which phase of the Cisco Lifecycle Services strategy may prompt a network redesign if too many network problems and errors arise in the network? prepare plan design implement operate optimize Which portion of the enterprise network provides access to network communication services for the end users and devices that are spread over a single geographic location? enterprise edge campus module WAN module Internet edge data center

Cisco Discovery Protocol Spanning Tree Protocol Address Resolution Protocol Dynamic Trunking Protocol VLAN Trunking Protocol
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 that 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 in the access layer. It reduces overall network traffic by grouping server farms, the management server, corporate intranet, and e-commerce routers in the same layer. 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
