network+ exam

What to know:

1. Multiple choice practice questions are good, do as many as you can. 
2. THERE ARE SIMULATIONS ON THE EXAM. 
• These simulations describe a scenario that you need to fix, what they don't do is give you operating instructions for the simulations themselves. 

Concepts to Study

• OSI Model, there are very few TCP/IP model questions 
• psychical network configuration 
• know cable ratings, their color, and their properties, their usage 
• Know important protocols & port numbers and their functions 
• Be Able To:
• compare the layers of the OSI and TCP/IP models
• Know all of the layers, the order they go in, and their fuctions 
• Classify how applications, devices, and protocols relate to the OSI model layers
• i.e. switches, routers, servers, etc. 
• Explain the purpose and properties of routing and switching
• identify common TCP and UDP default ports 
• explain the function of common networking protocols 
• 
  
• given a scenario, implement the following network troubleshooting methodology 
• idenfify virtual network components 
• in a digital model, identify  the router, switch, etc.
• Given a scenario, install and configure routers and switches
• given a scenario, install and configure a wireless network
• given a scenario, troubleshoot common wireless problems given a scenario, troubleshot common router and switch problems 
• given a scenario and a set of requirements, plan and implement a basic SOHO network 
• categorize and contrast different wireless standards 
• categorize WAN technology types and properties 
• given a scenario, troubleshoot common physical connectivity problems
• identify components of wiring distribution
• explain the purpose and features of various network applicances
• given a scenario use appropriate hardware tools to troubleshoot connectivity issues 
• given a scenario use appropriate software tools to troubleshoot connectivity issues 
• given a scenario use the appropriate network monitoring resource to anaylze traffic
