What Is The CCNA R/S?
First, letâ€™sÂ quickly review what the Cisco Certified Network Associate in Routing and Switching (CCNA R/S) is all about. Cisco tells us that if you have the CCNA R/S certification, you should be able to install, configure, operate, and troubleshoot a medium-size routed and switched network.
The newly updated CCNA R/S (i.e version 3) has these exam numbers:
- ICND 1:Â 100-105
- ICND 2: 200-105
- CCNA: 200-125
Can You Still Take The Old Exams?
If youâ€™re currently studying CCNA version 2 materials, thereâ€™s still time to take the version 2 exams. Specifically, you can still take the composite CCNA version 2 exam (200-120) through August 20, 2016.
You can also take the ICND1 version 2 exam (100-101) through August 20, 2016. Of course that only gets you part way to your CCNA certification. So, Cisco gives you through September 24, 2016Â to take your ICND2 version 2 exam (200-101).
A High-Level Comparison
In this blog posting, Iâ€™ll focusÂ on the exam blueprint of the composite CCNAÂ exam, with the understanding that these topics areÂ divided between the ICND1Â and ICND2 exams if you take the â€œtwo stepâ€Â path.
Hereâ€™s the high-level breakdown of the oldÂ 200-120 CCNAÂ exam, showing major topic areas and the percentage of exam questions coming from those areas. Operation of IP Data Networks: 5 percent
- LAN Switching Technologies: 20 percent
- IP Addressing: 5 percent
- IP Routing Technologies: 20 percent
- IP Services: 10 percent
- Network Device Security: 10 percent
- Troubleshooting:Â 20 percent
- WAN Technologies:Â 10 percent
In contrast, hereâ€™s the high-level breakdown of the new 200-125 CCNA exam. Network Fundamentals: 15 percent
- LAN Switching Technologies: 21 percent
- Routing Technologies: 23 percent
- WAN Technologies: 10 percent
- Infrastructure Services: 10 percent
- Infrastructure Security: 11 percent
- Infrastructure Management: 10 percent
What Topics Were Removed?
- Contrast bridges and hubs.
- Describe VRRP.
- Discuss GLBP.
- Troubleshoot Layer 1 issues.
- Troubleshoot Frame Relay.
- Monitor NetFlow information.
- Describe the following WAN technologies: VSAT, Cellular 3G/4G, T1/E1, ISDN, DSL, and Frame Relay
What Topics Were Added?
- Describe how cloud resources impact an enterprise architecture. This topic includes a discussion of traffic paths to internal (e.g. enterprise) and external (e.g. cloud) resources, virtual services, and basic virtual network architecture.
- Configure and verify LLDP (Link Layer Discover Protocol). LLDP is an industry-standard protocol that performs similar features to CDP (Cisco Discovery Protocol).
- Configure, verify, and troubleshoot multi-area OSPFv2 for IPv4 networks. The previous CCNA version only required that you be able to configure and verify single area OSPFv2. However, this configuration is basic, and does not include authentication, filtering, manual summarization, route redistribution, stub areas, virtual links, or LSAs.
- Configure, verify, and troubleshoot VLAN Trunking Protocol (VTP) version 1 and 2.
- Configure, verify, and troubleshoot multi-area OSPFv3 for IPv6 networks. The previous CCNA version only required that you be able to configure and verify single area OSPFv3. However, this configuration is basic, and does not include authentication, filtering, manual summarization, route redistribution, or stub areas.
- Configure, verify, and troubleshoot EIGRP for IPv6 networks.The previous CCNA version only required that you be able to configure and verify EIGRP for IPv4 networks. However, this configuration is basic, and does not include authentication, filtering, manual summarization, route redistribution, or the stub feature.
- Configure, verify, and troubleshoot RIPv2 for IPv4. The previous CCNA version did not include any version of RIP. However, this configuration is basic, and does not include authentication, filtering, manual summarization, or route redistribution.
- Configure and verify Multilink PPP (MLPPP). This feature allows multiple physical interfaces to be logically bundled into a single virtual interface, which can improve WAN throughput.
- Describe Internet VPN options, including Dynamic Multipoint VPN (DMVPN), site-to-site VPN, and client VPN.
- Configure and verify a single-homed eBGP (External Border Gateway Protocol) IPv4 connection. Personally, this is the biggest surprise on the new CCNA blueprint, because BGP topics have traditionally been considered too advanced for the CCNA certification. However, the BGP configuration is a basic one, limited to peering and route advertisement using only the network command.
- Describe Quality of Service (QoS) concepts. This topic includes the theory of marking traffic, trusting certain devices (e.g. Cisco IP Phones), prioritizing some traffic types over others (e.g. preferring voice traffic over network gaming traffic), setting a speed limit on traffic using policing and shaping, and congestion management (i.e. using queuing technologies to allocate bandwidth amounts for different traffic classes).
- Describe how to secure network access using 802.1x.
- Explain how to use DHCP snooping to prevent a malicious user from adding their own DHCP server to a network, for the purpose of sending inaccurate IP addressing information to DHCP clients.
- Verify IPv6 Access Control Lists (ACLs). The previous version of the exam only tested on IPv4 ACLs.
- Verify Access Control Lists (ACLs) using the APIC-EM Path Trace ACL Analysis tool, where APIC-EM stand for Application Policy Infrastructure Controller â€“ Enterprise Module.
- Discuss how to secure devices using AAA (i.e. Authentication, Authorization, and Accounting) with either the TACACS+ or RADIUS protocols.
- Using ICMP echo-based IP SLA to troubleshoot connectivity. Instead of using a basic Ping command to test for connectivity, the IP SLA features allows youÂ to specify the characteristics of traffic sent to a destination network device.
- Be able to use the Local Switched Port Analyzer (SPAN) features to troubleshoot network issues. SPAN allows you to connect a network monitor to aÂ switch port. That port can then receive a copy of traffic seen on another of the switchâ€™s ports or VLANs, allowing the network monitor to analyze that traffic.
- Discuss network programmability in an enterprise network architecture. This discussions covers the function of a controller, the separationÂ of the control plane and the data plane, and northbound vs. southbound APIs.
