PSI browser latency problems - Awfull experience - CKAD exam
I took the CKAD exam last monday May 16/2023 and yesterday May 20/2023 from Spain with a very good fiber service.
The experience with the exam was awfull both days with continuous latency problems on the PSI browser:
- in the vim editor , problem to recognize esc and :
- writing k run pod ... appearing 5 seconds after writing it
- copy pastes puting odd characters inside vim even though i did :set paste before
any random key suddenly writting gggggggggggggggg or hhhhhhhhhhhhhhh like crazy during lines and lines ... messing all the work I was doing in the VIM editor
unresposive mouse clicks simply to scroll up & down on the k create ingress name -h options in the terminalI did complain to proctors but they were just saying open a ticket on IT
- All these ruined my exam, I failed
I took KillerShell both practices and the Katakoda free ones, several times, where there are no latency problems, the contents are accurate and the working experience is nice and you can have with a big screen monitor with your laptop. In fact KillerShell practices are harder, in terms of knowledge, than the real exam on PSI browser.
Come on, I am an experience IT guy used to work with remote shells, and It was imposible to complete the exam for me. I have worker with servers in South/North America even China behind the "Great Firewall" and the unseen latency experienced specially yesterday was ruining any changes to do a successful exam. I failed.
I do not care about CKAD my real goal is CKA but I am not going to take it meanwhile these latency problems with PSI browser are gone.
Please consider to have properly dimensioned infra in Europe for the PSI browser.
As mentioned before KillerShell and Katakoda are all fine, but the PSI browser sucks. Besides, many of us may be working from laptop, and not being able to have a decent big screen with the PSI Browser, makes the exam a battle against no proper technical conditions and not testing the K8S knowledge.

I can confirm the same bad exam experience during my CKS exam on Saturday, 1st of July 2023 performed through PSI Secure Browser.
There were 3 tools I used in the remote desktop and all of them had lag:
1. Firefox Browser for kubernetes documentation
Scrolling was very slow and twice a "scroll-action" "hung" and a very long article in k8s documetation did not stop to scroll all the way down.Mousepad text editor to save and edit some code snippets
Copying and pasting was slowTerminal for SSH and bash
Very often my commands hung while typing for example "kubectl getttttttttttttt" and could only be stopped by "ctrl+c".
Further while using vi editor copying and pasting and typing was so laggy that sometimes simple keystrokes took 1-2 seconds.
My experience during the last years:
- I did my CKA in August 2021 still on the old environment on my private local browser which went great
- I did my CKAD in November 2022 on the new PSI remote environment and the lag was already there and I had a bad experience
- Now in July 2023 I did my CKS and this time the experience was the worst ever.
I am a professional IT engineer with 20 years of experience on Linux and other OS and I am very disappointed that such an experience of remote desktop issues made the exam extra complicated by losing time, having to repeat commands.
Even if I already was sure about the particular solution of a task or question, I could not complete it as quickly as I wanted due to the PSI browser.
For preparation I trained on the killer.sh exam simulator and the performance of it was good. Not perfect, but acceptable.
I must say, that I do not blame PSI browser for me not passing the exam in the first try (I have to study a bit more and will try again), but I will not attend any certification again which uses PSI secure browser technology.

I concur. What a piece of garbage. So much time lost that no one is going to return.

I had the same problems during my exam this monday. Terrible lags and really poor performance during exam. No problems at killer.sh test environmentalso, which is similar to exam environment. Expected you have to use chrome and not the psi browser. I opened also a ticket, they wrote they can not see any problems on exam side infra. I suggest that I can troubleshoot the issues together with the support outside of an real exam situation, to understand why this happens and if its a problem from psi- or my Infrastructur. Because it makes no sense to repeat session, if such performancelags can again occur. I wait for the answear since yesterday.

Hi @mario76eder,
We are sorry to hear about your experience. Did you open your ticket with the Linux Foundation Customer Support team at trainingsupport.linuxfoundation.org?
Thank you,

I post a ticket to them, 2 days ago, not any response, feel sad for that

So so so sad! I would wait for them to have a better exam environment before buying any voucher.

the PSI browser is just pain - its absolutely not possible to act like you do when preparing for the exam. There must be an improvement.

It's bad experience for my first try. It's very slow and lag

Same terrible experience taking the CKA exam today. Single Keystrokes responding with multiple keys, unresponsive UI, terminal etc. I couldn’t take the exam like that so i asked the PSI technical support for assistance but they told me this was Linux Foundation issue. I ended up not being able to do the exam at all and instead submitted a ticket with Linux Foundation.

You all are not alone in this mess. I experienced the same issue yesterday. There were questions I normally would have been able to answer but couldn't. At one point, I got so frustrated that I exclaimed, "COME ON" out loud during my exam session. The invigilator then gave me a warning, unaware of the struggles I was going through (see attached ticker).
Additionally, I also faced an issue with last alphabet for example "g" appearing multiple times. For instance, when trying to use a command like sudo nano /etc/ssh/ssh_config, it resulted in sudo nano /etc/ssh/ssh_configggggggggggg.
By the way, I just found out about an hour ago that I failed with 58%(LFCS). I decided to look online to see if others had experienced similar problems, and I came across the
posts along with complaints from others.0 -
Same i gave my exam today and experience was pathetic, it went well for first hour but after that it was next to impossible to work with remote desktop. I raised issue multiple times in live chat, the proctors were not able to do anything beside opening a ticket. My last one hpur was completely wasted i tried doing every other question, but it did not get better.
Did any of you got another chance and did the test work fine the other time ?

I took the exam yesterday and faced the same problem: random keys suddenly writing 'gggggggggggggggg' or 'hhhhhhhhhhhhhhhh' like crazy while typing lines. Was this my fault, or was something wrong on my side? I know that a lot of people had the same issue, and it was annoying and quite stressful during the exam, especially since I paid a lot for it and expected a professional experience.

I'm supposed to still be writing the ckad exam as of this moment as I type this. It is so frustrating, I couldn't type. My network was perfect.. my key strokes come out as "gggggggg", "cleeeeeaaaarrrrrr" with screen blinking. It is terrible, I couldn't get halfway through the exam. It is frustrating.. Had to open a ticket, hopefully they reply.

I would like to extend my heartfelt gratitude to the Linux Foundation team, especially @zuzanna.pn, for their exceptional support in assisting me with a retake opportunity for my exam. I am thrilled to share that I am now officially certified, and I couldn’t have achieved this milestone without their help. Thank you once again for your invaluable assistance!
