Cisco announced the ICND1 and ICND2 exam refresh from version 2.0 to 3.0. With this update, what has actually changed? The Cisco Learning Network Team has provided a list of delta’s that help outline what specific topics have come and gone.
What has changed?
The first change is the exam numbering for ICND1, ICND2 and the CCNA Composite exam. The new exam numbers are as follows:
||NEW EXAM NUMBER
Besides new exam numbers, there are some significant changes to ICND1, ICND2, and CCNA Composite exams… with the addition and removal of content from each exam. This blog will help you navigate these changes, so read on.
What are the details?
ICND1 v3.0 vs ICND1 v2.0
Key Topics Removed or Moved to ICND2 Exam:
- OSPF (single area) and other OSPF topics were moved into ICND2 since RIP is used to introduce CCENT candidates to IP routing protocols.
- Dual Stack was removed since there are many different IPv4 to IPv6 transition technologies being used.
- Cisco Express Forwarding (CEF) has been removed.
Key Topics Added:
- High level knowledge of the impact and interactions of infrastructure components in an Enterprise network, specifically:
- Access Points
- Wireless Controllers
- Awareness of the Collapsed Core architecture compared to traditional three-tier architectures. This option collapses the Distribution and Core into a single tier with the Access as the second tier.
- Configure and verify IPv6 Stateless Address Auto Configuration (SLAAC).
- Added Anycast to the list of IPv6 addressing types.
- Knowledge of Link Layer Discovery Protocol (LLDP). An L2 discovery protocol used in addition to Cisco Discovery Protocol.
- RIPv2 for IPv4 as the primary focus for understanding of how routing protocols work.
- Added requirements to understand DNS and DHCP related connectivity issues.
- Understanding of Syslog message logging for device monitoring.
- Skills and knowledge of device management related to backup and restoring device configurations, IOS feature licensing, and configuring time zones.
ICND2 v3.0 vs ICND2 v2.0
Key Topics Removed:
- Frame-Relay and Serial WAN technologies are no longer covered.
- VRRP and GLBP have been removed from First Hop Redundancy Protocols. Only HSRP remains since it is most commonly deployed.
Key Topics Added:
- Knowledge of dual-homed vs single-homed Intelligent WAN topology options.
- Basic knowledge of external BGP (eBGP) used to connect Enterprise branches.
- Expanded VPN topics to include DMVPN, Site-to-Site VPN, and Client VPN technologies commonly used by Enterprises.
- Understanding of how Cloud resources are being used in Enterprise network architectures, including:
- How cloud services will affect traffic paths and flows
- Common virtualized services and how these coexist with a legacy infrastructure
- Basics of virtual network infrastructure (Network Function Virtualization)
- Awareness of Programmable Network (SDN) architectures including:
- Separation of the control plane and data plane
- How a controller functions and communicates northbound to network applications and southbound to the R&S infrastructure using APIs.
- How to use the Path Trace application for ACLs which is a key new network application enabled by the Application Policy Infrastructure Controller – Enterprise Module (APIC-EM). This tool automates the troubleshooting and resolution of complex ACL deployments.
- Understanding of QoS concepts related to marking, shaping, and policing mechanisms used to manage congestion of various types of traffic. The need for QoS and how it is used for prioritizing voice, video and data traffic. Plus an understanding of the automation provided by programmable networks to implement business critical QoS policies.
Network operators are starting small with their SDN and Network Functions Virtualization (NFV) deployments, containing them to parts of the network where they can evaluate performance before rolling it out, according to Infonetics Research. The market research firm recently surveyed global service providers, representing 53% of worldwide telecom capital spending, to determine the timing and priority of SDN and NFV implementations.
Infonetics found that most are isolating SDN and NFV projects to “contained domains” of their networks to kick the tires before widespread deployment. Despite the cautious testbeds, momentum for SDN and NFV is strong, Infonetics reports, as the majority of operators participating in the survey plan to deploy the technologies in the core, aggregation and customer access tiers of their networks.
But that might take a while. Infonetics believes it will still be “many years” before SDN controls larger operator domains or a whole service provider network.
Interest in SDN and NFV is being driven by demands for operational efficiency and quicker turn up of revenue generating services. Study participants rated content delivery networks (CDNs), IP multimedia subsystems, and virtual routers/security gateways as the top applications for NFV, Infonetics found.
The top 5 network domains targeted by operators are: within data centers; between data centers; operations and management; CDNs; and cloud services. Eighty-six percent of surveyed operators also plan to deploy SDN and NFV technology in their optical transport networks as well, once standards are finalized, Infonetics found.
