This e-book is a concise one-stop table reference and synopsis of uncomplicated wisdom and abilities for Cisco certification prep. For starting and skilled community engineers tasked with construction LAN, WAN, and knowledge heart connections, this ebook lays out transparent instructions for fitting, configuring, and troubleshooting networks with Cisco units. the total diversity of certification themes is roofed, together with all features of IOS, NX-OS, and ASA software program. The emphasis all through is on fixing the real-world demanding situations engineers face in configuring community units, instead of on exhaustive descriptions of features.

This functional table significant other doubles as a entire assessment of the uncomplicated wisdom and abilities wanted through CCENT, CCNA, and CCNP examination takers. It distills a entire library of cheat sheets, lab configurations, and complex instructions that the authors assembled as senior community engineers for the advantage of junior engineers they educate, mentor at the task, and get ready for Cisco certification tests. earlier familiarity with Cisco routing and switching is fascinating yet now not helpful, as Chris Carthern, Dr. Will Wilson, Noel Rivera, and Richard Bedwell commence their publication with a evaluation of the fundamentals of configuring routers and switches. all of the extra complex chapters have labs and workouts to enhance the techniques realized.

This e-book differentiates itself from different Cisco books out there by means of imminent community safeguard from a hacker’s point of view. not just does it supply community protection strategies however it teaches you ways to take advantage of black-hat instruments reminiscent of oclHashcat, Loki, Burp Suite, Scapy, Metasploit, and Kali to really try the safety thoughts discovered.

Readers of Cisco Networks will research

  • How to configure Cisco switches, routers, and information middle units in usual company community architectures
  • The abilities and data had to go Cisco CCENT, CCNA, and CCNP certification exams
  • How to establish and configure at-home labs utilizing digital machines and lab routines within the publication to perform complicated Cisco commands
  • How to enforce networks of Cisco units assisting WAN, LAN, and information heart configurations
  • How to enforce safe community configurations and configure the Cisco ASA firewall
  • How to exploit black-hat instruments and community penetration suggestions to check the safety of your network

Example text

Fiber optic cable has benefits over copper wire because it has higher data rates and, therefore, it can be used over greater distances. Optical fiber cable can carry much more data than copper and it can be run for hundreds 23 Chapter 2 ■ The Physical Medium of miles without needing repeaters, which improves the reliability of the transmission since repeaters commonly fail. Fiber is also not susceptible to electromagnetic interference (EMI), thus it is less susceptible to corruption of data by other electronics, power cables, or other sources of EMI.

Along the way, packets traverse many locations through routers before reaching its destination. To view an example of this, open your command prompt on your laptop or workstation. com. You will see the number of routers that the packet traverses to its destination. There are many protocols in use at the Internet layer, including: • Internet Protocol (IP): The IP receives datagrams from the transport layer and encapsulates them into packets before forwarding to the network interface layer. This protocol does not implement any acknowledgement, and so it is considered unreliable.
