Why would you use the -replace flag for terraform apply?

Rationale for Correct Answer: terraform apply -replace=ADDRESS forces Terraform to replace the specified resource during the next apply, meaning it will plan to destroy and then recreate it (or create-before-destroy if the resource supports it and the graph/lifecycle allows). This is used when a resource is unhealthy, drifted in a way that’s hard to correct, or you want a fresh instance without changing configuration.

Analysis of Incorrect Options (Distractors):

A: Incorrect—-replace is not “destroy only”; it’s destroy + recreate.

B: Incorrect—ignoring changes is done with lifecycle ignore_changes, not -replace.

D: Incorrect—destroying everything is terraform destroy (or apply with all resources removed), not -replace.

Key Concept: Forcing resource replacement using -replace in the apply workflow.
