Exam environment migration to k8s 1.8

Budai Laszlo <laszlo.budai@...>
 

Hello all,

when it is expected to migrate the exam environment to Kubernetes 1.8?
After the migration can we expect tasks that are only working on Kubernetes 1.8? (using the new features introduced after 1.6)

Thank you,
Laszlo

stats of CKAs by country

Caio Begotti
 

Hi everyone! I wonder if CNCF or Linux Foundation have and could share stats of CKAs by country? I'd like to perhaps even get in touch with other Brazilians who passed (to form a Telegram group chat for networking) but I believe personal contacts cannot be shared?

Cheers

Re: grading between Beta and GA

Clyde
 

Great question! Any exam taken after yesterday is officially considered part of GA. You won't notice much change on the surface though since the questions are the same and the passing grade will not change, it remains at 74%. The two big differences are behind the scenes. First, the beta highlighted several cases (as many of you are painfully aware) where the exam environment was buggy and those have been addressed. Second, is that the grading scripts have had a lot of tuning to return more robust results. We did a huge amount of manual review of exam item responses during the beta to identify gaps between what the candidate did and what the grading script was expecting. Again, as several of you experienced, the manually graded scores were higher and the grading scripts are now more accommodating.

On behalf of the entire team at CNCF and The Linux Foundation I want to again thank everyone who participated in all the pre-launch testing. Your patience and resilience with the beta bugs and excellent feedback have made for a tremendously improved CKA exam and the future classes of certified individuals are forever in your debt.

Regards

Clyde

about exam again

Hosam Al Ali
 

Dear Gentlemen, 

I had finished from re-take the beta CKA exam at 8/9 at 8:00 AM Saudi Arabia +3GMT, 
My comments below 

- Wait for 35 minutes for the exam to be ready and launch button appears on exam page, I had checked with Proctor and his feedback to wait for the exam be ready.
- Experienced a slowness and reload the exam page many times and this impact the entire exam time because it is required a lot of YAML files to be written.

there are more than 5 questions I had no time even to read it and this will impact the exam grade as well 

regards, 
Hosam Al Ali

hello,

I posted this previously but everything was replaced with a link - maybe because of the pictures. If you click on the links you can find the pictures and the original text. I've just seen that because the digest is my preference over individual emails.
Besides that I read that "For each question you'll see the point value at the bottom and we're    relocated some items so that fewer high value questions are at the    end. However, since we're trying to minimize the amount of manual
    navigation across the different clusters, you'll still find that the second 'half' has a higher point value than the first 'half'." But as far as I remember I didn't see points. But that' s not so important to me but maybe I was on an older version of the exam?

hello,

today I tried to take an exam but I gave up eventually.

First the exam was very slow and the terminal was unusable. It was laggy and slow. After every command I had to wait 10-15 secs to get the prompt back. And that was not because I deployed hundreds of pods it was the same for kubectl get pods and kubectl get pv etc.
I issued the command "w" to see the load and it was 44.23.... I checked the number of cores before I complained to the proctor. The VM or bare metal had 16 core (/proc/cpuinfo is very helpful). I told him about my problem. He asked me to be patient and tried to get help.
Than the connection was lost. When it was restored I checked the load numerous times and it was still between 22-35. Ok, it was a bit more responsive, still slow.
I had connectivity problems as well. The connection was lost several times and when I noted that and that the terminal is slow the proctor told me that's because my connection is slow.... Yeah, the load level as high as 44 because of the speed of my connection? LOL. Besides that it's a 120Mbit connection and I know that towards various datacenters it's not same but I checked it after the exam (you see my tests below).
Once the connection lost and restored I found a clear, grey terminal without any prompt..... I asked the proctor for help and they reseted something - the connection lost and restored. After that I tried to schedule a deployment but I got an error that the etcd service is unavailable.....
So, I found out the hard way that this exam is still very-very beta in terms of the exam environment. I gave up at this time because the previous exam was very slow and it was in "ungradable state" whatever it means - I think the environment and the screen and camera record was lost or damaged. I didn't want to sit 5 hours in front of the computer to waste another 5 hours from my life - 4 hours for the exam, 1 hour for the various related stuff like checking my identity and waiting to repair the exam env.


I also checked my internet connection towards the exam environment. I found out from the firewall logs that I had lots of connections towards amazon aws when I started the exam. And I know that the screen and camera stream goes towards there because I had to disable some protection in the firewall (invalid ssl packets towards the exam environment) when I took the previous exam. To make a long story short I checked my connection towards Amazon AWS with the help of https://cloudharmony.com/speedtest-for-aws and everything was fine. I connected to eu-west-1 datacenter I attach the edited screenshot - I just cut the interesting part out to make the picture smaller but I can send you the whole image - and you can see the detailed connection test as well on separate pictures. So, I don't think the speed of my connection caused any problems.
So the problems didn't went away. Previously the exam was just a bit slow to me but I was able to do the test - I didn't check the load back then - it just turned out that the whole sank into a blackhole... or such a thing.

I know it's a beta exam and the environment is complex and demanding lots of horsepower but when can we expect a stable environment to take and exam without any glitches? Should we just wait a bit and don't try again soon - that's my intention - and do you have a schedule?

br, Agoston

Hi, I see the tech notes on the cluster setup for the beta exam say it does
not need to follow best practices because it is a controlled env etc etc
etc, but are best practices graded in the exam? For instance, if we are
asked to create a Pod... in the real world I would never do that, instead I
would create, say, at least a Deployment object with the Pod in it, but I
can go ahead with just a Pod in the exam due to time constraints or best
practices ARE actually graded? This is not clear to me, yet.

Hi Ciao,

The grading scripts look for the end state on the system in terms of
what the candidate is specifically asked to do, not at whether best
practice was followed.

I found the environment slow, short time to be able to validate as the

times I needed a refresh on the page.

Hi, I finally took my beta exam and at some point when I was working my way
to question 29, with about 1h remaining, the cluster stopped responding to
all kubectl commands. Cluster-info showed only master was up, no signal of
etcd so I suppose the whole thing was not going to play ball anymore.

I tried to take a screenshot of that to show you guys here but the proctor
freaked out immediately and treated to terminate my exam. I tried to
explain to him what was going on but it seems proctors have zero context of
what is going on with the exam and its content and its environment...
bummer.

So, bottom line is that I think I did well with about 21 questions
answered. As for the remaining ones, question 29 was answered on disk
/home/student/q29.conf but not applied to the cluster due to the problem
above. I left other 2 pretty questions (one to sort CPU usage and another
one I can't recall now) for last but I guess I was too dumb in doing so, I
could have got 2 more answered fine. All the others I had left for last
(basically the troubleshooting ones) were left behind for good...

I don't now how this will be graded, nor it anything done to the cluster
was my fault or what but I tried to look around for some Juju and Snap fu
tricks to restore etcd from a working unit in the cluster but I guess the
one we log in to is set up differently than the Juju units via CDK. CDK I
think protects "local" snaps like etcd so there is not way to bork the
cluster, but somehow the outer env where /home/student is I think people
will quite easily bork it if it keeps the way it is today when the exam
goes live!

Re: notes on cluster problems when taking my beta exam tonight :-(

Hi Caio,

Thanks for reporting this, sounds like one that hasn't been reported before and I'm sure it was both stressful and annoying. We'll definitely grade around it for your exam so that you're not penalized and I'll provide this info to the relevant team so they can triage what happened (we keep the machines alive for a day or two post exam so should be able to do a thorough analysis).

As for your second note about etcd, I'm sending you a separate (off-list) note to introduce you to the engineer who can work through it with you.

Regards

Clyde

best place/way to discuss questions wording and answer

Caio Begotti
 

Hi, I do have a general thing to discuss about the wording of a etcd-related question I have seen both in the alpha and beta exams that I think is either misleading or I am just clueless about the problem (though I honestly doubt that). Is this ML a place for this? It might involve discussing the answer to it so I'm a bit undecided. I'm open for discussing it in private anyway.

The grading scripts look for the end state on the system in terms of what the candidate is specifically asked to do, not at whether best practice was followed.

Hi, I see the tech notes on the cluster setup for the beta exam say it does not need to follow best practices because it is a controlled env etc etc etc, but are best practices graded in the exam? For instance, if we are asked to create a Pod... in the real world I would never do that, instead I would create, say, at least a Deployment object with the Pod in it, but I can go ahead with just a Pod in the exam due to time constraints or best practices ARE actually graded? This is not clear to me, yet.

about exam again

hello,

I posted this previously but everything was replaced with a link - maybe because of the pictures. If you click on the links you can find the pictures and the original text. I've just seen that because the digest is my preference over individual emails.
Besides that I read that "For each question you'll see the point value at the bottom and we're relocated some items so that fewer high value questions are at the end. However, since we're trying to minimize the amount of manual
navigation across the different clusters, you'll still find that the second 'half' has a higher point value than the first 'half'." But as far as I remember I didn't see points. But that' s not so important to me but maybe I was on an older version of the exam?

hello,

today I tried to take an exam but I gave up eventually.

First the exam was very slow and the terminal was unusable. It was laggy and slow. After every command I had to wait 10-15 secs to get the prompt back. And that was not because I deployed hundreds of pods it was the same for kubectl get pods and kubectl get pv etc.
I issued the command "w" to see the load and it was 44.23.... I checked the number of cores before I complained to the proctor. The VM or bare metal had 16 core (/proc/cpuinfo is very helpful). I told him about my problem. He asked me to be patient and tried to get help.
Than the connection was lost. When it was restored I checked the load numerous times and it was still between 22-35. Ok, it was a bit more responsive, still slow.
I had connectivity problems as well. The connection was lost several times and when I noted that and that the terminal is slow the proctor told me that's because my connection is slow.... Yeah, the load level as high as 44 because of the speed of my connection? LOL. Besides that it's a 120Mbit connection and I know that towards various datacenters it's not same but I checked it after the exam (you see my tests below).
Once the connection lost and restored I found a clear, grey terminal without any prompt..... I asked the proctor for help and they reseted something - the connection lost and restored. After that I tried to schedule a deployment but I got an error that the etcd service is unavailable.....
So, I found out the hard way that this exam is still very-very beta in terms of the exam environment. I gave up at this time because the previous exam was very slow and it was in "ungradable state" whatever it means - I think the environment and the screen and camera record was lost or damaged. I didn't want to sit 5 hours in front of the computer to waste another 5 hours from my life - 4 hours for the exam, 1 hour for the various related stuff like checking my identity and waiting to repair the exam env.


I also checked my internet connection towards the exam environment. I found out from the firewall logs that I had lots of connections towards amazon aws when I started the exam. And I know that the screen and camera stream goes towards there because I had to disable some protection in the firewall (invalid ssl packets towards the exam environment) when I took the previous exam. To make a long story short I checked my connection towards Amazon AWS with the help of https://cloudharmony.com/speedtest-for-aws and everything was fine. I connected to eu-west-1 datacenter I attach the edited screenshot - I just cut the interesting part out to make the picture smaller but I can send you the whole image - and you can see the detailed connection test as well on separate pictures. So, I don't think the speed of my connection caused any problems.
So the problems didn't went away. Previously the exam was just a bit slow to me but I was able to do the test - I didn't check the load back then - it just turned out that the whole sank into a blackhole... or such a thing.

I know it's a beta exam and the environment is complex and demanding lots of horsepower but when can we expect a stable environment to take and exam without any glitches? Should we just wait a bit and don't try again soon - that's my intention - and do you have a schedule?
