Today, the networking is one of the most important areas of concern, because of the use of the worldwide computer network used by the majority of the users. The computer network means the interconnection between the number of computers and the permission or access to their data and resources. The network system with the interconnection of autonomous computers forms an integrated computing system using the networking software. It is possible to have the geographical distribution of computer communication for exchange of data and information. The networking system provides a number of advantages to the users, such as:
- Simultaneous executionofprocesses
- Coordinationof the activities with each other
- Communication and transfer of data
The network consists of a hardware and software system for performing work on the creation of computer networks to allow the communication between computers. Therefore, there is a need of engineers who can understand the network hardware and software systems. Cisco is a company that provides hardware and software components for a networking system. Hence,it becomes necessary for engineers to be trained in network systems and system operation.
Such a training program conducted by Cisco is known as CCNA or Cisco Certified Network Associate. This is the associate-level certification that it is regarded as a Cisco career credential.
The candidates who want to achieve the CCNA R&S 200-125 certification should pass the certification exams. These tests are designed to show the knowledge, skills, and ability of individuals. The networking engineer needs such skills as network installation and operation of the network of different varieties. The maintenance is an important function when the candidates need to troubleshoot problems with a small and corporate network. The candidate must know the routing and switching system and their basics. A network engineer must implement a network security and authorization system that supports the security of IP addresses and network protocols. The engineers should understand the TCP/IP and OSI models used in IP-based networks and systems. There are various WAN technologies whose operation and configuration of ISO devices are known. VLANs are used in an enterprise system with advanced dial-up networks that define IP routes and traffic management systems using an access list.
The CCNA Security certification exams are provided in the areas of networking fundamental, LAN and WAN technologies, software and hardware of network system, security and management of the system, and wireless technology. The examinations check the ability of candidates to work on the networking technology such as design of network, hardware construction, software system and security, maintenance and testing of the network system.
The field of the networking is developing rapidly because the employers are interested in recruiting the certified engineers for such advanced technologies as wireless networking, security, administration, cloud computing, data center establishments, etc. Therefore, the CCNA R&S tests have the questions relating to these areas.
The networking engineers need to know the network fundamentals better, and they should be able to understand the network settings and concepts. These CCNA 200-125 R&S examinations offered by Prepaway.com deal with these basic concepts and understanding, thus, the candidates who will passthe exams may have jobs such as:
- Network technician
- Network engineer
- Network software engineer
- Maintenance engineer
- Development engineer
- Research engineer
- Network security engineer
- Network administrators
The following certification exams are associated with the CCNA Security certification. An individual should take one of them to become a certified specialist.
200-125 CCNA: This examination contains 60-70 questions and lasts 90 minutes. It measures the individuals’ knowledge and ability associated with network fundamentals, WAN and LAN technologies, IPv4 and IPv6 routing technologies, infrastructure security, services, and management.
100-105 ICND1: This certification test is an hour and a half exam with 45-55 question assessment. It verifies the skills and knowledge of candidates related to infrastructure maintenance and services, network fundamentals, LAN switching technologies, androuting technologies.
200-105 ICND2: The exam consists of 45-55 questions with a time duration of 90 minutes. It confirms that an engineer has the knowledge and skills associated with IPv4 and IPv6 routing technologies, infrastructure maintenance, infrastructure services, WAN and LAN technologies.
The exam passing score is not published by Cisco since the examination questions change without notice.
Undoubtedly, the candidates with the CCNA R&S certification can hope for a bright future in such advanced area as networking. The individuals who have earned this credential, can declare themselves as highly qualified professionals.Therefore, those candidates who pass the CCNA R&S exams will receive excellent job opportunities with a high pay hike. The average salary of the CCNA R&S certified specialist ranges from $260,111 to $ 921,142.
