Keep your network running and help your business run more effectively. In this course, you will examine fundamental application layer protocols an their operation including, HTTP, FTP, DNS, DHCP, NTP, and Syslog.
In a business, the entire purpose of the data network is to make the business function more effectively through the use of software applications. In this course, Application Layer Protocols for Cisco CCNA 200-125/100-105, you will examine critical application layer protocols that both help keep the network running, as well as allow end users to easily access resources on the internal network as well as the Internet. Then, you'll learn about the application layer protocols that assist engineers in maintaining the function of a network efficiently, like DHCP, DNS, Syslog, and NTP. Engineers use these protocols to maintain networks, and create an effective user experience. Finally, you'll learn about the other application layer protocols, like HTTP and FTP, and how they are used by the users themselves to browse to websites or download files. By the end of this course, you will have the foundational knowledge of DHCP, DNS, FTP, HTTP, NTP, and Syslog. You will even learn how to investigate a strategy to mitigate rouge DHCP servers from attacking your network.
Course Overview Hi everyone, my a name is Ross Bagurdes and welcome to my course Application Layer Protocols. I'm a network engineer with 20 years experience building and managing enterprise networks and teaching people about them. Building a data network is a somewhat useless task, unless we use it to pass data between devices. To pass this data we use application layer protocols, like HTTP, SSH or Telnet. Additionally we use a group of somewhat quite protocols that work behind the scenes to make our network operate successfully. In this course we will learn about client server operation, we'll discuss HTTP clients and servers, we'll look at Telnet and SSH, unencrypted and encrypted communication. We're going to examine DHCP operation and look at a rogue DHCP server and how we can mitigate a tax from rogue DHCP servers. We'll also look at DNS, Domain Name System, which is the telephone directory for the internet. By the end of this course, you'll know how to troubleshoot DHCP and DNS issues on work stations, and before beginning this course you should be familiar with TCP and UDP, IP addressing and network operation, which can be learned from the previous videos in this CCNA series. From here you should feel comfortable diving into access control lists and the rest of the courses in the CCNA series. I hope you join me on this journey to learn about HTTP, DNS, and DHCP with application layer protocols at Pluralsight.
