CCNA Routing and Switching Overview

What is routing and switching? Routing involves moving data packets between different networks.  Switching involves moving data packets between devices on the same network.

Routers operate at layer 3 of the OSI Model. A router is able to determine where to send a packet using the Network ID within the Network layer header. It then uses a routing table to determine the route to the destination host.

Switches, on the other hand, operate at layer 2 of the OSI Model. A switch, also referred to as a multi-port bridge, is able to determine where a packet should be sent by examining the MAC address within the data link header of the packet (the MAC address is the hardware address of a network adapter). A switch maintains a database of MAC addresses and what port they are connected to.

Cisco Certified Network Associate (CCNA) Routing and Switching is a certification program for entry-level Network Engineers that helps to highlight the efforts you’ve made in accumulating foundational networking knowledge and increases your value to your employer’s network. CCNA Routing and Switching is for Network Support Engineers, Network Administrators, and Network Specialists with 1-3 years of experience. CCNA Routing and Switching verifies the certificate holder’s ability to install, operate, and troubleshoot medium-size routed and switched networks using Cisco equipment.

Exam and recommended training

The best way to prepare for the CCNA Routing and Switching certification exams is to take this Cisco-approved training at a Cisco-authorised training establishment, such as Logitrain in Australia:

Interconnecting Cisco Networking Devices Part 1 (ICND1)

This course focuses on providing the skills and knowledge necessary to implement and support a small switched and routed network. At the end of this training course, customers will be able to sit the 100-101 CCNA examination. This exam tests a candidate’s knowledge and skills required to successfully install, configure, operate, and troubleshoot a small branch office network. The exam includes topics on the Operation of IP Data Networks; LAN Switching Technologies; Network Device Security; IP Routing Technologies; IP Addressing (IPv4 & IPv6); IP Services (DHCP, NAT, ACLs); Basic Troubleshooting.

Interconnecting Cisco Networking Devices Part 2 (ICND2)

This five-day course focuses on using Cisco Catalyst switches and Cisco routers that are connected in LANs and WANs typically found at medium-sized network sites. At the end of CCNA training, customers will be able to take the 200-101 CCNA examination.  This exam tests a candidate’s knowledge and skills required to successfully install, configure, operate, and troubleshoot a small to medium size enterprise branch network. The exam covers topics: IP Routing Technologies; IP Services (SNMP v2 and v3, FHRP, Syslog); LAN Switching Technologies; WAN Technologies; Troubleshooting.

Interconnecting Cisco Networking Devices: Accelerated (CCNAX)

This five-day training consists of ICND1 and ICND2 content in their entirety but merged into a single course.   At the end of this training, customers will be able to take the 200-120 CCNA Routing and Switching examination which covers the same material as exams 100-101 and 200-101 mentioned above.
