For those taking exam 3V0-21.20 (also known as Advanced Deploy VMware vSphere 6.7) then you’ll know that the exam is a real lab that you need to fix issues in or change configuration based on given scenarios.
This post runs through how to use version 2 of my VCAP Deploy Exam Simulator. In the older version, I provided the lab environment but this was difficult to maintain and I wasn’t able to schedule the simulator fast enough for everyone.
This version of the simulator uses the VMware Hands-on-Labs environment which is very similar to the real exam environment. Furthermore, it is online all the time so you can freely go through the lab questions below without having to wait for an available slot or wait for me to open a session for you.
Below I provide 17 questions, just like the real exam and you have the same time to complete them. I provide the answers in guide form under each question (hidden by default) so you can try to figure it out before opening the answers to check your work.
Launching the Exam simulator
Since the real exam is based on the Hands-on-Labs environment, it makes a lot of sense to use the same environment to answer the practise questions
- Click here to open the Hands-on-Lab environment
- You may need to login/register
- The HOL can take a few seconds to open. Ensure your pop-up blocker doesn’t interfere
- Extend the time to approximately 3.5 hours to best simulate the exam time of 200 minutes (Hit the extend button)
- Open Google Chrome to familiarise yourself with the bookmarks
- Notice that there is a notes button on the top of the screen. This contains the vCenter credentials
- Close the manual on the right
- Maximise the lab screen
YOU’RE READY TO GO!!
- My practise exam questions are below. They cover various sections of the exam blueprint
- None of the questions are knowingly taken from the real exam
- Complete each question at a time. Skip something if you don’t know how to do it. Come back to those question(s) at the end if there is time
- Expand the answer section to see the answer. Click the images within the answer section to make them larger (They open in a new tab so you won’t lose your place)
- Please send any feedback to me and I’ll do my best to update the questions and answers
- Enjoy!

Exam tips
Do not waste time reading the documentation. Time will pass VERY quickly so if you are not sure about a question, mark it for review and go back to it later.
The exam interface is very similar to the Hands on Labs (HOL)
Documentation should be available on the desktop but if you need to use it you will run out of time. Only read the documentation if you have unanswered questions at the end of the exam.
Once again, read through the blueprint and ensure you can complete everything listed, this is the key to passing the exam!
