Haha, tell me about it! It's like they're trying to keep us on our toes or something. But hey, at least it's not as bad as some of the AWS service names. Have you seen 'Amazon Kinesis Data Streams'? Sounds like a new age meditation technique!

Hmm, I've seen the TF_VAR prefix used quite a bit in Terraform examples, so that's my guess. Although, I can't help but wonder why they don't just use something more intuitive, like ENV_VAR or something. These tech companies and their cryptic naming schemes, am I right?

Alright, TF_VAR it is. Sounds good to me. Time to move on to the next question and see what other Terraform traps they've set for us. At this rate, I'm going to need a thesaurus just to understand the exam!
