Nowadays, many companies utilize a network to exchange information and services. The network’s performance and security have become of the utmost importance as vulnerabilities could lead to massive breaches in data integrity and disruption of services. When it comes to network infrastructure, certbolt is one of the names that first come to mind because of its hardware and software products.
Keeping up with new technologies is essential to networking professionals. In this article, we will describe the widely adopted Cisco IOS software and how you can acquire IOS operation skills by passing the Cisco 100-490 exam.
Cisco IOS Software
Cisco IOS software is a technology that is actively used in over a million systems worldwide. It is the operating system software for the certbolt hardware such as routers. In the 1980’s Cisco IOS was used in routers to handle packet forwarding and path discovery. Today it evolved to serve a multitude of services such as telecommuting trafficking and Layer 3 switching, among others.
Cisco IOS software has branched out to several newer versions such as IOS XE, IOS XR, and NX-OS. These versions were designed to address weaknesses in the classical IOS and provide solutions for specific use cases. In the next paragraph, let’s take a look at more details on these versions.
Cisco IOS Versions
There are 4 main versions of certbolt software and these are as follows:
- IOS – The classical version that started in 1980. It’s a monolithic kernel, i.e it has its own multitasking kernel and protocols to carry out its functions.
- IOS XE – The XE is a modular operating system that introduced multiple programmability features, multiple cores, control plane, data plane support, etc. One of the main advantages of such a system is that the kernel is unaffected by the failure of single processes within modules, which was the case in the IOS.
- IOS XR – This is designed to accommodate larger service providers like the ASR and CSR series of routers. This is because the XR can execute multiple protocol processes simultaneously in separate memory spaces.
- IOS NX-OS – With the support for Fiber Channel Over Ethernet (FCOE) to enable a unified fabric of the certbolt traffic and LAN traffic. This fabric helps data centers cut down on equipment purchases, space, power, and cooling costs.
The Cisco 100-490 Exam
Professionals that have Cisco-specific skills are highly valuable in the industry. Taking the Cisco 100-490 exam, also known as Supporting Cisco Routing & Switching Network Devices, is the fastest way to gain expertise in IOS software operation, networking equipment, networking fundamentals, and service-related knowledge.
Cisco provides a comprehensive online self-paced course called Supporting Cisco Routing and Switching certbolt (RSTECH) v3.0 to help candidates prepare for this evaluation. Successful completion of the Cisco 100-490 exam grants you the CCT Routing and Switching certification that validates your competency in onsite support and maintenance of Cisco routers, switches, and operating environments.
Conclusion
IOS Software is a game-changer in the network industry. If you are pursuing a career that involves onsite support and maintenance of Cisco operation environments, then IOS software operation skills are crucial. You can take the certbolt to demonstrate your ability to handle IOS technologies and knowledge of Cisco networking hardware.
