Description

This course provides an introduction to the basics of internetworking. The different network models used to maintain, organize, and troubleshoot Cisco systems are also presented in detail. IEEE media standards covered include the Ethernet, Fast Ethernet, Gigabit Ethernet, ATM, Token Ring, and wireless standards.

Objectives

• Describe the responsibilities of each layer of the OSI Reference model and the types of devices found at each layer
• Articulate the steps involved in the Internetwork Troubleshooting model
• Know and identify different LAN topologies
• Understand different LAN devices in a network
• Understand and apply Ethernet technology
• Describe the capabilities of ATM and its advantages

Description

This course provides an introduction to Windows troubleshooting techniques. Command syntax and how its used in troubleshooting Windows issues is presented for the most commonly used commands such as ipconfig, ping, tracert, nslookup, netsta,ftp, and telnet. In addition, troubleshooting common problems from Windows clients is discussed.

Objectives

• Troubleshoot connectivity issues in the network using the commands ping, pathping, and tracert, and using the appropriate syntaxes with each of these commands
• Use the ipconfig and winipcfg commands to add, remove, and troubleshoot Dynamic Host Configuration Protocol (DHCP) information on a hosts interface
• Understand the nslookup command and its modes and syntaxes in order to troubleshoot and resolve DNS query problems
• Understand the route command, its syntaxes, and its subcommands in order to use them to statically add, change, and remove known routes through the network on the local host
• Use nbtstat and netstat command syntaxes in order to troubleshoot many problems in your network and on the local host

Description

This course focuses on Virtual LANs (VLANs), which were created by the different switch manufacturers to provide individual broadcast domains. By assigning each port to an individual VLAN, each VLAN becomes its own broadcast domain. Additional topics presented include VLAN trunks, pruning, route processing, and troubleshooting switched connections and routing configuration

Objectives

• Differentiate between trunk links and access links
• Use VTP and VTP pruning
• Differentiate between dynamic and static VLAN ports
• Differentiate between internal and external route processing
• Configure VLANs, trunking, VTP, and VTP pruning on a Catalyst switches
• Troubleshoot switched connections
• Troubleshoot inter-VLAN routing configurations

Description

This course discusses the different dynamic routing protocols used in Cisco networks and explains how they work. The commands related to troubleshooting routing protocols that the learner needs to know to pass the exam are described. The last part of the course provides an overview of NetWare\'s routing protocols and the connection sequences and the diagnostic tools that relate to troubleshooting in an IPX (internetwork packet exchange) environment.

Objectives

• Understand the differences between static and dynamic routing
• Articulate the different types of routing protocols
• Use IOS commands to troubleshoot routing protocol problems
• Explain the inner workings of Novell IPX
• Understand and know how to troubleshoot SAP
• Describe how GNS messages work and when they are used
• Configure and troubleshoot IPX access lists
• Understand the advantages and disadvantages of RIP and NLSP

Description

This course provides practice exam questions for the Cisco CIT 642-831 exam.
