What is a network visualizer? A network visualizer is software that is used in CCNA applications so that you can connect with the network of another user. Most network visualizers are equipped with chat components
that are used to connect and communicate with other users within the network, and a public chat room where you can connect and chat with people that are using other network visualizers.

Internet connection is a must before you can use a network visualizer. It is also recommended you use cable connection or DSL to reap the benefits of connecting with other users. With dial-up connections, you may just
get slow speed and poor connectivity.

Network simulators or network visualizers allow the user to build, configure and design his own network with the use of drag and drop functions. This personal network will probably be equipped with numerous commands.
Network visualizers are commonly used by professionals who study CNNA, such as corporate employees and trainers, instructors, and students in networking academies, colleges and universities.

Some network visualizer software includes unlimited devices whose only limitation in design is related to your computer screen resolution. These unlimited devices also include in the software the use of net packets which
you can view through the network; Net detective which is used for troubleshooting, and testing network and scan failures in your network; the copy-paste command that makes it easier to configure the executable
programs and commands in your screen; interface labels which you can view, and display, and may even include a host name for every IP Address; and sets of learning labs.

Examinations in CCNA will test your ability to create switching systems for LAN or WAN, routing and Cisco IOS. Your examination in CCNA may also include configuring, Internet working, and troubleshooting with the use of switches and routers.
Usually, the CCNA exam would cost $125.00 – pass or fail – with the passing score set at 849/1000. You need to get 45 out of 55 questions right, which are composed of multiple/single answer, multiple choice, and drag and drop options; as well as fill in the blank queries, and router simulations. All this should be finished within 75 minutes.
Before you place yourself in CCNA examination environment, make sure you have knowledge about installing and operating LAN and WAN; configuring and switching LAN; configuring IPX, IP, RIP, IGRP, Ethernet Interfaces/Serial, access lists and VLANs; configuration of router protocols in a network; connecting through dial-up; and understanding OSI model thoroughly so that you get better results in the exam.
Be well informed about switching and bridging, Layered Communications and OSI reference model, network protocols, routing, Network Management, LAN design, Cisco Basics, Network Basics and IOS. These are usually the topics in a Cisco Certified Associate Exam (CCNA). Tutorials are also available on the Internet to give you a helping hand at honing your skills before taking the exam.
This CCNA exam is also available in Japanese which is offered in Japan exclusively. Through the use of the Internet, you can locate, schedule, cancel or reschedule, confirm and perform a CCNA Exam. Taking the exam and passing it will certify the taker as a professional in CCNA and officially gives the professional the benefits of being confident about their skill and knowledge level.
