Why Certifications Methods?

Hey there, Let’s take a step back and change our perspective: Approach certifications as a means to enrich your knowledge and skills, rather than merely a stepping stone to monetary gain or career advancement. Certifications should be about self-improvement and mastery , not just a checkbox on a resume. Embrace the journey of learning for its own sake, and watch how it transforms your personal and professional life in ways you never imagined. The Real Reason Behind Certifications The commercial marketing driving force of certifications is often centered around securing a new or better job. But I urge you to reconsider if this is your primary motivation . Take a moment to reflect on your personal development and your deepest interests within the realm of technology.  Is your passion in: Programming Crafting elegant code and solving complex problems? System Administration, Ensuring seamless operations and managing vast networks? Data Analytics Unraveling the stories hidden within data?

WAN Problem Areas Certification Objectives Point-to-Point Protocols Switched Protocols      In this chapter, we will discuss troubleshooting point-to-point and switched protocols. It’s very important to understand the concepts and functionality of each protocol. We will discuss the HDLC and SDLC encapsulation methods, as well as both CHAP and PAP authentications via PPP. We will identify ISDN, Frame Relay, X.25, SMDS, and ATM transmissions and common problems associated with each of them. Point-to-Point Protocol      In the 1980s, the Internet really started to come to life due to its usage by the U.S. government, universities, and large corporations. These hosts were being supported by the Internet Protocol (IP) and connected via a series of LANs. The most common of these LANs was the Ethernet. Other hosts were connected through WANs, using technologies such as X.25. This eventually evolved into the need to transmit data via the original method used before networking was ever establis
