I just wanted to point out the following since I know that you didn’t realize this was a problem
Final Question 4 stated the following.
“When the write has been applied by the nodes marked in yellow , it returns an acknowledgement back to the client.”
Being colour blind. I had no idea which nodes were yellow. I couldn’t tell if more than was coloured the same or not. It was nearly impossible for me to get this question right on my own even though I knew the material and I knew what you were asking.
I had to face time a friend and show them the screen and tell me which boxes were which. This could have easily been solved if you simply used stripes or something else just an FYI.
