  Exam Description  
 

The Designing Cisco Networks exam (DCN 640-441) is the only exam required to achieve a CCDA certification.

 
  Exam Topics  
 

The following topics are general guidelines for the content likely to be included on the Designing Cisco Networks exam. However, other related topics may also appear on any specific delivery of the exam.

Identify Customer Needs
•  Identify tools you can use to characterize existing customer's network and determine its current performance status
•  Describe a framework that you can use to identify and analyze customer's business constraints, needs, problems and design solutions
•  Characterize the customer's existing network by gathering customer data to be used in your internetwork design solution
•  Identify the type of platform and network management tools used in existing network
•  Determine the customer's requirements for new applications, protocols, number of users, peak usage hours, security, and network management
•  Identify typical customer network performance and security requirements

Design the Network Structure
•  Explain the reasons for employing a hierarchical network design model
•  Describe the structure of the hierarchical model
•  Describe the four types of redundant models: workstation-to-router, server, rout, and media
•  Explain how to implement redundant model in various environments
•  Describe the three-part firewall system
•  Recommend bastion hosts to provide secure services
•  Design the Cisco Secure PIX Firewall series into a three-part firewall system
•  Identify the steps (or process) required to design a network addressing model

Build a Prototype Network Structure
•  Determine the amount of the network structure that you must build to prove that your internetwork design meets the customer's needs
•  List the tasks required to build a prototype network
•  List Cisco IOS software commands you should use to determine whether a network structure meets the customer's needs
•  Describe how to demonstrate your validation findings to the customer

Internetworking Basics
•  Identify and describe the functions and process of communication by the seven layers of the OSI reference model
•  Describe the basic process of information exchange between two applications across a network
•  Distinguish between basic protocol information formats and describe their uses in data communications
•  Identify and describe the elements of a hierarchical network, as specified by ISO
•  Define the term protocol, and describe the difference between network architecture, such as the OSI model, and a protocol

•  Describe data link addresses and network addresses, and identify the key differences between them
•  Define and describe the function of a MAC address
•  Identify the three most commonly used methods to learn the MAC address of a network device, and describe their basic operation
•  Describe a flat address space and a hierarchical address space, and identify the key differences between them
•  Identify the difference between static address assignment, dynamic address assignment, and server address assignment
•  Identify the key differences between names and addresses in an internetwork
•  Define flow control and describe the three basic methods used in networking
•  Define error checking and describe the basic operation of the CRC
•  Define multiplexing and describe its function in internetworking
•  Identify the major standards organizations and bodies that specify internetworking standards

LAN Protocols
•  Recognize scalability constraints and issues for standard LAN technologies
