ICND2 v3.0 vs ICND2 v2.0
Key
Topics Removed:
1. Frame-Relay and Serial WAN technologies are
not any longer coated.
2. VRRP and GLBP are far away from initial Hop
Redundancy Protocols. Solely HSRP remains since its most ordinarily deployed.
Key Topics Added:
1. Data of dual-homed vs single-homed
Intelligent WAN topology choices.
2. Basic data of external BGP (eBGP) won't to
connect Enterprise branches.
3. Swollen VPN topics to incorporate DMVPN,
Site-to-Site VPN, and shopper VPN technologies ordinarily utilized by
Enterprises.
4. Understanding of however Cloud resources the square measure being employed in Enterprise network architectures, including:
· How
cloud services can have an effect on traffic ways and flows
· Common
virtualized services and the way these exist with a heritage infrastructure
· Basics
of virtual network infrastructure (Network perform Virtualization)
5. Awareness of Programmable Network (SDN)
architectures including:
· Separation
of the management plane and information plane
· How a
controller functions and communicates north to network applications and south
to the R&S infrastructure victimization arthropod genus.
6. The way to use the trail Trace application
for ACLs that could be a key new network application enabled by the applying
Policy Infrastructure Controller – Enterprise Module (APIC-EM). This tool
automates the troubleshooting and backbone of advanced ACL deployments.
7. Understanding of QoS ideas associated
with marking, shaping, and policing mechanisms wont to manage congestion of varied
kinds of traffic. The necessity for QoS and the way it's used for prioritizing
voice, video and information traffic. And associate understanding of the automation provided by programmable networks to implement business essential QoS policies.
