1.1) Sys admins generally have their own set of tools (which would be customized per company I guess)...would these be installed by default? (I'm assuming you are provisioning docker containers / candidate / test and then destroying them after use).
1.2) I've used the ones that are sent for developers and it's been a pretty terrible experience at best (it's buggy, won't accept valid code etc.). If this is the case for sysadmins, it's even more worse (but then again, I guess you can put a spin on it and claim it's for the best as they'd have to deal with unpredictiability).
2. How will different technologies be integrated to test candidates on? (for example, testing knowledge on multi node kubernetes cluster and so on).
