Today was my first attempt at EX280 which I, unfortunately, did not clear.
I failed by a close margin and haven't given up yet.
I noticed something which led to my downfall in the exam:
As per OpenShift documentation, "however, it is recommended to use Deployment objects unless you need a specific feature or behavior provided by DeploymentConfig objects."
DeploymentConfig was not covered in DO280 training. Any reason that DeploymentConfig is used/tested?
There are several features which was not covered in DO280 but may appear on exam.
I know it exactly. For example taints/tolerations - search this forum with "ex280" keyword.
Also self-signed certifs - they are written in exam objectives.
Why deploymentconfigs used instead of deployments - I think exam was created in old times when deploymentconfigs were used and still didn't edited.
I think it's better don't rely on RH courses if they recommend modern forms or resources - you should know both forms - modern and previous versions and be ready to use them (for exam).
