This video contains 3 Terraform interview questions with answers.

📝 Questions & Answers:

Q1: What is `ignore_changes`?
A1: `ignore_changes` tells Terraform to ignore specified attributes during diffs so external edits aren’t overwritten. Example: Like agreeing not to track minor interior decorations that the tenant can change without landlord interference.

Q2: What is `terraform taint` (deprecated) and `terraform apply -replace`?
A2: `taint` marked a resource for recreation on next apply; modern practice uses `-replace` to force recreation. Example: Like flagging a faulty part so it gets replaced on the next scheduled maintenance.

Q3: What is `lifecycle` in a resource?
A3: `lifecycle` config controls creation/update/delete behavior (prevent_destroy, ignore_changes, create_before_destroy). Example: Like special delivery instructions that prevent tearing down an old bridge before a new one is ready.
