Network+, 4.3 IP Version 4 Subnetting – TestOut

Exam Objectives Covered: 

  • 1.7 Given a scenario, use appropriate IPv4 network addressing. 

Links:

Overview:

Organizations with large networks need to divide those networks up into smaller segments to improve performance and security. A network segment is represented at the Network layer by a subnet. Additionally, IPv4 uses a system of public versus private addressing that determines how hosts and networks can connect over the Internet. Understanding the features of these addressing schemes will be essential to your career in network support.
