This video is the first in a series of videos covering major topics on Cisco's new CCNA exam, 200-301.
This video covers Quality of Service (QoS).
If you want access to the 2nd and 3rd training videos, please register for your FREE CCNA Mini-Course at: kwtrain.com/cc...
In Video #2 you'll learn about Spanning Tree Protocol (STP)
In Video #3 you'll learn about Wireless LAN (WLAN) standards
Finally, in Video #4, I'll share my story with out about how I got into an IT career, and I'll help you decide if it's right for your, or not.

what a great guy in whats hes achieved and what he stands for. i just failed my CCNP 300-410 today with score of 780, gutted but got get straight back on the studying band wagon. starting new study material with kevin wallace training vids. keep up good work kevin

Shaping = Less assertive, puts a delay on packets that may go over the Bandwidth limit.
Policing = More assertive, drops packets that exceed Bandwidth limitations.

[@anithasoundararajan2978]

Thank you for doing this Kevin. It made Qos a lot more approachable.

[@BeeBumper]

I feel you, a lot of topics in CCNA I am very comfortable with but there are several that seem so overwhelming that are harder to emulate using PT although PT has come a long way in terms of simulating some great features. I find QOS is a topic I have made a lot of ground on since first starting but again I often feel I need more and have yet to reach the comfortable level I have with other topics. It is a daily thing and I will just keep plugging forward.

I've never seen such a cool faucet

[@stanleychijioke-nwolisa6423]

Hi Kevin, great work and simplified delivery too. I particularly love the real life analogies used to explain various concepts.

[@EdsterL]

I took out of the video how QoS can be broken down so that everyone can have a piece of the pie. Today in my environment we have one wire that feeds our computer and sip phone, but like you said it knows or it has been programmed on the switch via VLAN to distinguish which one has the priority.

Hi Kevin,
I liked the RTP explanation in reference to VoIP, queuing, TCP and windowing. Thanks

[@arontigerful]

My take away from this course
The best definition of Qos is managed unfairness
3 categories of Qos are
- Not restricted - Best Effort
- Less restricted - DiffServ
- Strict - IntServ
Common Quality of Service Mechanism
- Classification and Marking: recognize that the type of traffic early and making a marking so that the next router or switch very efficiently look at that marking and making a decision whether
dropping or forwarding based on that marking.
- Queuing: it is known as congesting management, giving a priority treatment for type of packets (for example VOIP)
- Congestion avoidance: is preventing a queue from filling a capacity
- Policing and Shaping: is called a traffic conditioner which prevents traffic from sending too rapidly.
- Link efficiency: some of the mechanisms are compression, link fragmentation and interleaving ... it is a big deal when we trying to make the most effiecient use of our link speed on speed
less than 2mb per second, or in some cases 768kbs
Thank you for the course.

my concept got better now, thanks for expalining in plane english

[@lkdipeolu]

Fragmentization is key for me. I will like get more of it.

[@rukundoagira6364]

Thanks so much Kevin, Great voice out there, Well my take was about the QoS Mechanisms most especially Queuing, Congestion Avoidance. Thanks once again.

[@just_the_job]

Awesome accent, great video. Greetings from the UK.

[@sharanappakattimani8294]

Sir doing good job👍

[@vu2957]

Such a great tutorial.. hats off

[@arammaldonado2451]

You motivated me with all your cool certs! Lol Cheers!

[@aaajojoaaa]

Thank you . you r the best.

[@apollosolutions9961]

Goof stuff I think I got that QOS is needed for periods of congestion stood out for me

[@ostropogask9415]

you are doing the Lord's work

[@omarsbeta9120]

videos 2 and 3 are locked on the website.
how can I get access to them.

[@skr0nytbe389]

Hi Kevin, it was a great video. Short one but it clearly explained the basics of QoS with analogical examples. Great work. I tried to access the other videos on Spanning Tree, but unable access in your website. What could be the reason? They are showing locked.

[@kwallaceccie]

Thanks! Once you sign-up for the mini-course, subsequent videos will be unlocked one at a time over the next few days for you. You'll receive and e-mail letting you know when the next video is available. I hope you continue to enjoy the training.

[@bobdavislumbro4047]

Is QoS usually configured on the router or switch? Or both

[@Silverballer48c]

You should get into voice acting

[@TheLithGH]

0:25 I can't seem to find a job, because companies are posting job descriptions for ALL forms of IT in ONE position. Must know R/S, wireless, Security, Cloud, VoIP, Server Admin, Firewalls, etc, etc... brutal, hahaha

[@yonatanmakara6856]

Security i would love tonget into. Always a demand for them

[@ANALOGTecHII]

Can you provide full traing for CCNA certification.

[@kwallaceccie]

I do indeed have a full CCNA course. More information about it is given at the end of the Mini-Course. You can signup for the Mini-Course at kwtrain.com/ccna-mini

[@nabeelyousaf7512]

you r looking handsome here.
