• Online, Self-Paced

Networks are the basic interconnections for all computing devices. Discover fundamental elements in network communication, including routing and switching concepts as well as IP addressing components as you prepare for exam N10-007.

Learning Objectives

Concepts and Characteristics of Networking

  • start the course
  • describe concepts and characteristics of network traffic, such as Broadcast, Multicast, and Unicast
  • describe concepts and characteristics of network traffic such as broadcast domains, CSMA/CD, CSMA/CA, and Collision domains
  • describe concepts and characteristics of segmentation
  • describe the purpose and characteristics of hubs, switches, and routers
  • describe concepts and characteristics of routing protocols
  • describe concepts and characteristics of IPv6 such as addressing, dual stack, router advertisement, and neighbor discovery
  • describe concepts and characteristics of performance concepts such as traffic shaping, QoS, Diffserv, and CoS
  • describe concepts and characteristics of NAT and PAT
  • describe concepts and characteristics of port forwarding
  • describe concepts and characteristics of access control lists
  • provide scenarios on when to use private and public IP addressing options
  • recognize scenarios of when to use loopback and reserved addresses
  • list scenarios of when to implement default gateways and subnet masks
  • provide scenarios and illustrate how to configure virtual IP addresses
  • configure address assignments such as DHCP, static, APIPA, and IP reservations

Subnetting and Supernetting

  • perform base 2 conversions
  • describe concepts of binary to decimal conversion and determining the size of a subnet
  • subnet a class c network
  • subnet a class b network
  • subnet a class a network
  • perform supernetting
  • determine the address ranges of subnets

Practice: Subnetting

  • configure a basic subnetting scenario
