Cisco is being a large leader in networking and technology business provides commercial solutions covering the PAN area to enterprise solutions to provide connectivity across the whole globe. Cisco having a renowned position in the market today and therefore it is the most favorite of the entire technology community. Do check out the training courses available at SPOTO Club to increase your knowledge. This blog will introduce several major Network Simulators for
Cisco Exams.
WHAT ARE NETWORK SIMULATORS?
Students who are preparing for their Cisco certification tracks, especially in the closing dates Network simulators have been playing an important role for them. It becomes vital for professionals to visualize the implementation of the infrastructure while testing them as per the scenarios with multiple scenarios to dangle with.
To simulate networking topology that may include multiple networking and internetworking devices these Network simulators are software are available. This software can simulate real networking devices but is bound by the limitations of commands and features that are already programmed into them which makes it difficult to learn about scenarios like Policy Based Routing, etc that can only be observed using real networking devices.
Experts are using these to practice and prepare for their certifications as well. The time you start preparing for your exam, it becomes extraneous at times how simulators with more featured are the go-to-tool and how these simulations can successfully replicate the scenarios with all the essential metrics in place is what the most candidate sought for.
MOST RECOMMENDED NETWORK SIMULATORS
The software assists with preparations and is possible. These software’s are used mainly to study the network infrastructure of the organization or any test case at hand. A complete list of tools has been listed below that covers most of the proficient tools.
- Packet Tracer
- GNS3
- NetSim
Let’s study tools.
Packet Tracer is being the Cisco proprietary network simulation tool that is capable of simulating Cisco networking and internetworking devices such as routers, switches, firewalls, etc. The software was originally a part of the education aid of NetAcad but later was made available for public use for free.
Pros:
Packet tracer is available for free having a very good cross-platform
Usage: Connections to provide a practical approach towards labs and the availability of a variety of devices.
Realistic Terminal allows a user to configure and troubleshoot technologies on the devices through a command-line interface.
Cons:
The devices available are limited to Cisco and so, people willing to try other technologies need to look for other alternatives to expand their horizons. Packet tracer lacks built-in labs that are overpowering for any new users that have just started working with the simulator.
GNS3 is a well-known network emulation tool that covers a large variety of vendors apart from Cisco. The simulator is available in the client\server application.
Pros:
The software package is free for individuals and offers community labs. The network topologies can be changed as the requirement.
The guidelines for all aspects of your requirements are available at ease in an excellent format as it being an open-source project.
Cons:
Cisco software would need proprietary Cisco Softwares or IOS images. Complex set up process for running simulations as well as the requirement of multiple components to run the latest version of the software.
NetSim is commonly known as Boson NetSim, is a simulator put forth by the Boson IT organization to assess and provide high-quality training for professionals who are for seeking Cisco certification.
Pros:
Scenarios establish specific Cisco exams and providing high-quality lab allowing access to realistic features of a network terminal and device customization options.
Cons:
Paid Tool and licensing fees for each Cisco module, keep a several consumers away pushing them towards their Cisco alternatives.
The lack of simulation modes, lack of topology information, and customization options make it a difficult choice for several candidates as tweaking of network topology is difficult.
