TF_VAR_NAME sounds like it might be right, since it includes the variable name. But I think the other options are more standard. Gotta go with TF_VAR on this one.

I'm leaning towards option D. 'TF_ENV_VAR' sounds like it could be the correct format for environment variables in Terraform.

Haha, I bet the exam question writer is sitting there chuckling, thinking 'let's see if they can remember the exact prefix!'. Well, joke's on them, I'm going with TF_VAR and I'm confident about it.

You know, if I get this wrong, I'm going to feel like a total 'terraform'.

I was leaning towards TF_ENV, since we're talking about environment variables here. But I guess TF_VAR makes more sense since it's specifically for Terraform variables. This exam is really testing the details, huh?

TF_VAR for sure, that's what I learned in the Terraform training I took. You use that prefix to set variables that Terraform can then pick up and use in your configuration.

Hmm, I'm not sure about that. I was thinking it might be TF_ENV_VAR, since that seems more descriptive of what we're trying to do. But I could be wrong, I'll have to double-check the Terraform documentation on this one.

This is a tricky one, the format of environment variables can be a bit confusing sometimes. I'd say the correct answer is TF_VAR, since that's the standard prefix used for Terraform environment variables.
