Not sure about that first one, seems a bit sketchy to me.

Wait, is the average of logs really lognormally distributed? Sounds off.

I thought the variance of averages is just the variance of individuals divided by n?

Okay, let's see. The question says we need to ensure Client1 can communicate with Vnet2, and the proposed solution is to resize the Vnet1 gateway. I'm not sure if that's the right approach here.

I think the key here is to focus on the differences between the components. The question is asking about the installation process, so I'll need to carefully read through the options and think about how each component is installed.

The initialization section sounds like the most logical choice here. That's where we configure the script before it starts running, so that makes sense as the place to set up the values and settings.
