Exam - Kibana version + Knowledge Freshness

Hello,
can anyone help me to answer these questions:

  1. I've read that ES version 7.2 will be used during the exam, what version will be Kibana?
    I've notices that Kibana 7.2 hasn't got so good Auto Complete function in Dev Tools (Ctrl + Space), e.g. in Aggegations.

  2. I've done ES I + II virtual (on demand - web ) so how long this knowledge will be sufficient to pass the exam? I'm asking because I'm not sure where I should pass the exam. I would like to have enough time for preparation : )

Thank you.

I've passed the exam, the version was 7.2 for ES and Kibana
you will be logged to a CentOS Machine from where you can access to all servers for labs
Es 1 & 2 are the best asset, mainly labs for Es 2
Good luck

Thank you @ylasri.
