A router, placed between the disparate units, would go a long way towards directing the traffic flow and making sure that everything to where it was going with as few points between as possible.

The 192.168.2.1 Infrastructure

As with any other computer device, IP address 192.168.2.1 makes use of routers to relay information to and from the Internet to the network node. Aside from using the NAT (Network Address Translation), the router includes a public IP address. This is what the computers on the network use as identifiers when going through the Net.

The fact you are reading this means you are planning to take your Cisco CCNA or another Cisco exam in fact and just knowing that means you may fall victim to one of the 10 fatal exam mistakes. I can speak with some authority on exam mistakes because over the past 8 years I have made most of them myself.

IT exams are usually taken at an approved testing centre who all have to follow set rules and procedures to ensure each candidate has a similar experience. The problem is that there are factors both outside and inside the centre which can make passing the exam far more difficult for you than it needs to be.

Without further ado, allow me to explain how to avoid the 10 fatal exam mistakes for your Cisco CCNA exam or any other IT exam for that matter.

When you started studying for your CCNA certification exam, one of the very first things you learned was the major difference between the enable password and the enable secret - the enable secret is encrypted by default, where the enable password is just sitting there in clear text, waiting to be read!

When you look at the enable secret in a Cisco router configuration, it looks like it would be impossible to guess. After setting the enable secret on this router to the word security, here’s how it appears in the configuration:

enable secret 5 $1$24me$gVFxUOI4gYp0IQbhtH8Rz0

That password has been encrypted by MD5, the Message Digest 5 algorithm. The result of the MD5 algorithm being applied to the password is a 32-character hexadecimal value.

Routing

Routing is a relay system by which packets are forwarded from one device to another. Each device in the network as well as the network itself has a logical address so it can be identified and reached individually or as part of a larger group of devices. For a router to act as an effective relay device, it must be able to understand the logical topology of the network and to communicate with its neighboring devices.
