In the exam, in the instruction page you will find the link to documentation page.
If you look at this page https://docs.openshift.com/container-platform/4.5/nodes/scheduling/nodes-scheduler-taints-toleration..., all the sections on left hand side of the page will be list of the sections in the documentation page in the exam. In the exam you can download the individual documentation on each section as pdf or view it as html. You will not have search box like one in the above page and you would need to know exactly which section would have the details you are looking for.
I hope it helps.
I currently studying for the exam. Was MohsinaSacha right about the documentation? Which version of the exam did you attend? So I can be sure to have documentation available during the exam? Just like  but without the search form? Would be really great if redhat officially announces that because this really changes how the learning is approached.
I had exam on 4.5 and yes there is documentation as described in exam objectives "
So keep practicing and know what to look where.
Can someone confirm if the RedHat documentation (https://access.redhat.com/documentation/en-us/openshift_container_platform/4.5/) is available or not on the exam? I find it a bit better than the openshift one.
Can any one please let me know which Rhel version and GNOME version EX280/288 exam supports ? Actally what I know the mouse genarally moves very slow in the exam environment and that kills a huge amount of time. Any suggessions here?
