All computers and network devices require an IP address to be able to connect to the Internet or other IP devices on an organizational network. In this course, you'll learn about the fundamentals of both DHCP and DNS and how DHCP can help automate the configuration of devices on an IP network. You'll explore start of authority records as well as the various DNS record types used to handle requests and translate domain names into IP addresses. You'll then review key characteristics of both the Network Time Protocol and IP Address Management. Next, you'll examine basic corporate and data center architectures, and common architectures such as three-tiered, spine and leaf. You'll learn key characteristics of software-defined networking and explore the storage area network and common connections types that include fiber channel, fiber channel over Ethernet, Internet small computer, and Systems Interface. Lastly, you'll learn about colocations and the benefits and solutions these data centers can offer. This course is one of a collection of courses that prepares learners for the N10-008: CompTIA Network+ certification exam
