The biggest News is the oldest Cisco Certification Track Routing & Switching is gone I have been telling Students for Quite past many years that Routing & Switching Track is fast losing value and so does the most popular Cisco Certification which was introduced
in 1998 by Cisco the CCNA Routing & Switching Certification.
- What's Wrong with Routing & Switching Track?
Let me start with a Question. How many Technologies which were developed in 1980-1990
are we still using?
In the field of Technology change is permanent. Routing & Switching Track was based on oldest
Connectivity Technologies, Local Area Network (LAN) and Wide Area Network (WAN) while a
Good degree of Ethernet LAN still exist but it's the WAN technology which was constantly going
downhill for past 10 years.
Growing Popularity of VPN has caused study decline in WAN Technology and it started crashing
by almost 30% for past 5 years. Data has overtaken Telecom sector in past decade and we all
must understand that all Routing and Switching technology have their base in Telecom
Increasing reliability and high bandwidth Internet connection available at very less price as
compared to WAN has led to large scale migration from WAN towards VPN and all of sudden
Routers started disappearing from Client site getting replaced by Firewall and VPN.
- Software Define WAN (SD-WAN)
is like final Nail in the Coffin for WAN market. BGP developed
in 1985 could never give us Load Balancing over Multiple ISP but SD-WAN has solved the oldest
Problem which we face while Designing Customer Sites.
IT will also make using WAN links less attractive now than ever. SD-WAN can give you more bang
on your bucks and suck the entire juice on those ISP link where we can now look to rock and roll
application based Forwarding and load balancing based on real time Latency , load and other parameters. Experience Network Engineers will tell you nightmares we use to have to roll out
such solution based on L3 headers and Clumsy QOS solutions
- Firewall is the New Router:
My first Experience of Implementing SD-WAN solution happened on
Barracuda Cloudgen Firewall. Barracuda calls it TINA VPN a preparatory solution and was blown
away as how easily it solved the year old problem of handing multiple WAN and ISP edge solutions
and trying to get best out of them and My next encounter of configuring SD-WAN came on
Fort iGATE Next Generation firewall .
While Cisco Might Try hard to save Routers but the writing is on the Wall Firewalls with VPN and
SD-WAN capabilities will be the Perimeter Device and they are the new age Routers and Routers
are all set to disappear from Customers sites.
What's New in CCNA 200-301 Certification: While a detailed list of topic can be found at the end
lets first try to understand the significance of the NEW CCNA Certification.
Single CCNA certification as pre requisite for all the Six Certification Tracks
Now this is where the this CCNA certification is like nothing you have heard or done before
replacing Eight Different CCNA certification and merging all the relevant fundamentals in a single
Foundation level Exam is such a huge challenge and so is the New CCNA certification.
Let's Focus on the Major Technology Sections which are totally new
- 1. Wireless LAN
No LAN Professional can be complete in this day and age without having Deep understanding of Deploying and Configuring Wireless LAN technology. I expect
Access Layer to be 90 % WLAN in coming years and that makes learning WLAN
an absolute must.
New CCNA Certification Covers WLAN Concepts as well Configuration
- 2. Network & Wireless Security:
Security is inseparable and give its Due in the
New Curriculum. All the required building blocks toward Network Security
are covered including Fundamentals of Security appliances, VPN, AAA and
Deploying WLAN security using WPA standards
- 3. Network Automation and Programmability:
Cloud Computing and
and Automation has finally found its way into the new Cisco Certification
and this is path breaking change as so far the very thought of Programming
was alien to a networking professional but not any longer
Understanding Separation of Control and Data plane. Controller based and
software defined architecture means you are finally into SDN
