Kristine Garrett | 15 May, 2018, 15:47

Research has shown that the gap in terms of general networking skills in getting narrower as the day goes by. However, the gap in skills for fundamental networking technologies like cyber ops, security, industrial, and wireless, as well as other emerging technologies, such as cloud, service provider, and data center, is increasing. The Cisco CCNA R&S curriculum and certification are designed to align with the fast changing global trends and job market.

The Cisco CCNA Routing & Switching curriculum is developed for individuals who are interested in picking up entry-level jobs in the ICT industry or want to keep abreast of the development in the implementation of Information Communication Technology in their field. The CCNA R&S certification offers a comprehensive and integrated coverage of networking subjects, ranging from basic to advanced applications while offering opportunities for career/skills development as well as hands on experience in the field.

Individuals interested in earning this Cisco certificate will be required to take the certification exam after completing the course. Understanding the curriculum will go a long way to help candidates develop the foundation and required skills needed to succeed in networking careers.

To fully understand the requirements of earning the certification, it is important to have a full grasp of the curriculum for the different levels of the CCNA questions and answers course. Below is the detailed information about the course curriculum.

CCNA One: Introduction to Networking

The CCNA One focuses on architecture, functions, structure, models, and components of the Internet, as well as other computer networks. The structure and principles of IP addressing and the basics of Ethernet concepts, operations, and media are initiated to offer a strong foundation for the course curriculum. At the end of the course, the candidates would have been able to develop simple LANS, implement IP addressing schemes, and be able to carry out basic configurations for routers as well as switches.

In summary, the applicants who have gone through this course would have developed the capacity needed to perform the functions below:

·         Identify and describe the services and devices needed to support communications in the Internet and Data Networks.

·         Identify and explain the important role of protocol layers in the data networks.

·         Describe the fundamental Ethernet concepts such as operations, media, and services.

·         Develop, calculate, and implement subnet addresses and masks to carry out specific requirements in IPv4 & IPv6 networks.

·         Identify and describe the significance of naming and addressing schemes at different layers of data networks both in IPv4 & IPv6 environments.

·         Create a simple Ethernet networking using routers & switches.

·         Use common network utilities to authenticate small network operations and evaluate data traffic.

·         Utilize CLI (Cisco Command-line Interface) to carry out fundamental router and switch configurations.

CCNA Two: Routing & Switching Essentials

This second course focuses on the architecture, operations, and components of routers & switches in small networks. The candidates will be required to learn how to configure a router & switch for fundamental functionality. At the end of the course, the individuals would have developed the capacity to troubleshoot and configure routers and switches and be able to correct common problems with RIPv1, inter-VLAN routing in IPv4 and IPv6 networking, Single and Multi areas OSPF, RIPng, and Virtual LANS.

In summary, the candidates should be able to carry out the following functions:

·         Identify and explain the fundamental of switching concepts and the implementation of Cisco switches.

·         Identify and explain the nature, purpose, and implementations of a router, route lookup process, and routing tables

·         Identify and explain how VLANS develop rational separate networks and how routing happens between the networks.

·         Identify and explain different vibrant routing protocols, link-state routing protocols, and distance vector routing protocols.

·         Troubleshoot and configure OSPF (Open Shortest Path First) network.

·         Troubleshoot and configure static routing & default routing.

·         Identify, troubleshoot, and configure access control lists for IPv4 and IPv6.

·         Identify, troubleshoot DHCP (Dynamic Host Configuration Protocol) for IPv4 & IPv6 networks.

·         Identify, troubleshoot, and configure NAT (Network Address Translation) operations.

CCNA Three: Scaling Networks

The Scaling Networks course explains the architecture, operations and components of routers & switches in more complex and bigger networks. The candidates will learn how to configure and troubleshoot routers & switches for more advanced functionality. At the end of the course, they will also be able to resolve regular issues with EIGRP, STP, and OSPF in IPv4 and IPv6 networks. In addition to this, they will also build their skills and knowledge levels required to implement WLAN in a small/medium network.

In summary, at the end of this course, the applicants would have developed the capacity to carry out the following functions:

·         Identify, troubleshoot and configure improved switching technologies like Per VLAN Spanning Tree Plus Protocol, Ether Channel, Rapid Spanning Tree Protocol, and VLANs.

·         Identify, troubleshoot, and configure First-Hop redundancy protocol in a switched network.

·         Identify, troubleshoot, and configure wireless routers & wireless customers.

·         Administer Cisco IOS Software licensing as well as configuration files.

·         Troubleshoot and configure routers in a multifarious routed IPv4 and IPv6 network utilizing single area OSPF, Enhanced Interior Gateway Routing Protocol, and Multi-area OSPF.

CCNA Four: Connecting Networks

The course is designed to explore network services and WAN technologies needed by converged applications in a compound network. The candidates going through the course will develop capacity to understand the selection conditions of WAN technologies and network devices to meet network prerequisite. The individuals will also learn how to troubleshoot and configure network devices as well as resolve different problems with data link protocols. In addition to this, they will also develop the skills and knowledge base required to execute virtual private network operations in a multifarious network. At the end of the course, the candidates will be able to carry out the following functions:

·         Identify and describe numerous WAN technologies and their advantages.

·         Identify, troubleshoot, and configure serial connections.

·         Identify and explain the operations and advantages of VPNs and tunnelling.

·         Identify, troubleshoot, and configure broadband connections.

·         Identify, troubleshoot, and configure network address translation operations.

·         Troubleshoot and supervise network operation susing SNMP, NetFlow, and Syslog.

·         Identify, troubleshoot, and configure tunnelling operations.

Conclusion

Before writing the CCNA R&S certification examination, it is important to understand the curriculum and take time to study the courses. In addition to this, ensure you read the exam policies and requirements before you register for the exam.
