Failed 2 times on EX380

Jump to solution
Greeting All,
I filled 2 times on EX380 yesterday and last month the strange thing is that my score is the same. However, my answer changed and was able to fix alot of stuff on yesterday exam and was sure that final application was working as expected on each question. I have a real concern on the grading script for this exam as it is also new exam just 4 month ago and there is no many people attended the same. Is there any chance to Red Hat team to do reevaluate the same manual any one has such experience to share as frankly speaking I have nothing to do more. Every thing was working as expected and if I did another retry I will add nothing!

The same problem here - getting 0% for the items which just worked for me - and it was a technical fact.  I would understand getting something like 40% if it was not done the way Red Hat expects - but 0% is just wrong for things which could be used for other tasks.  I opened a ticket with support, they could neither explain  nor comment anything.  I found some people on Linkedin who passed EX380 - and all of them did it with the previous exam version for OpenShift 4.6.  

I can only suspect broken logic in the estimation flow - when it stops after an incomplete item and doesn't try to check following items. But in this case, the whole exam should be either 0% or 100%.

It's certainly not unheard of that there's an issue with the validation / scoring scripts. It needs to be brought up with the exam development team, as @Lene indicated on the previous page. 

I've personally had this exact problem with EX413, when I took it a few years ago. The exam had been updated right before I took it and the dev-team had made mistakes in the scoring scripts. Both of my failed attempts I had actually passed, but the scoring script marked me wrong.

I tried - just formal replies.  Nobody can say anything.

Hello, I did it in the third attemp with a score of 248 (v4.10). Two objectives are scored with 0%. I have opened a ticket so that the result is checked again.

Hello, I received a dm asking me to give some tips. I can’t talk about the exam. But I will give some general tips how I learned with the course DO380 and the provided lab. 


Some general things:

DO380

  • The course does not have a “Comprehenisve Review” like D0280 or other courses. Challenge yourself with some complex tasks that combine multiple objectives.
  • The lab scripts prepare every exercise. Take a look at every resource they provide. Modify the provided resources to test different scenarios, provoke errors to learn/check events and logs, or challenge yourself and redo the same exercise from scratch. You can recreate the entire lab if something breaks (I had to do this several times)
  • Familiarize yourself with the OpenShift UI. Almost everything can be done from command line or UI. Sometimes the UI contains examples of specific resources, or you can copy and paste existing resources to create a new resource. Some tasks I can do much faster in the UI than via command line with multiple commands and yaml resources.

1. I use this command to search for specs, it's way more efficient than looking through the documentation PDFs or minimalistic UI YAML templates:

$ oc explain <something> --recursive

 

2. An OpenShift cluster contains resources, which can be used as examples in the tasks:

$ oc get <something> -A

$ oc get <something> -n <project name> -o yaml > example.yaml

 

3. Use "yaml-lint" to validate YAML files and "jq" for JSON files. 

 

4. Hardcode this .vimrc string into your memory and use it whenever you edit YAML:

autocmd FileType yaml setlocal ai ts=2 sw=2 et cuc

 

5. Vim has ":retab" command, which replaces tabs with spaces.  Tabs may appear when you copy/paste YAML code from the documentation. Close and re-open your yaml file, execute ":retab", close and re-open again.

Are tools such as kustomize already pre-installed?

to carry out exercises with kustomize it would be much more practical to generate, for example, the skeleton of the kustomization.yaml

I passed EX380 today, the score was 261.  Got 0% for two tasks that practically, technically WORKED.  Unfortunately, there is nobody to ask what was wrong.  Lack of this feedback is a serious flaw in the Red Hat examination system.
