HashiCorp Exam TA-002-P Topic 7 Question 35 Discussion

Actual exam question for HashiCorp's TA-002-P exam

Question #: 35
Topic #: 7

A developer accidentally launched a VM (virtual machine) outside of the Terraform workflow and ended up with two servers with the same name. They don't know which VM Terraform manages but do have a list of all active VM IDs.

Which of the following methods could you use to discover which instance Terraform manages?

ARun terraform state list to find the names of all VMs, then run terraform state show for each of them to find which VM ID Terraform manages

BUpdate the code to include outputs for the ID of all VMs, then run terraform plan to view the outputs

CRun terraform taint/code on all the VMs to recreate them

DUse terraform refresh/code to find out which IDs are already part of state

Show Suggested Answer

Suggested Answer: B

Use the depends_on meta-argument to handle hidden resource dependencies that Terraform can't automatically infer.

Explicitly specifying a dependency is only necessary when a resource relies on some other resource's behavior but doesn't access any of that resource's data in its arguments.
