Course description

Your infrastructure is set up, but what are you looking at when you look into it? In this course, six videos take you through the details of infrastructure services. Beginning with DNS (Domain Name System) and the process of turning domain names into IP addresses, we’ll look at DHCP (Dynamic Host Configuration Protocol) and its four-step process, troubleshooting DHCP, configuring and verifying NTP (Network Time Protocol), standard ACLs (access lists), NAT (network address translation) and more. Take a closer look at the processes and commands needed to show access lists or NTP associations, review NAT statistics and understand how to troubleshoot your network infrastructure.
