The answer is to add a `moved` block to the configuration that maps the old module address `module.network` to the new name `module.vpc`. This is the correct approach because the `moved` block is a declarative refactoring feature introduced in Terraform 1.1 that tells Terraform to treat the existing state resources as belonging to the new address, preventing any destroy or recreate actions. On the HashiCorp Terraform Associate TF-003 exam, this question tests your understanding of state management and refactoring best practices—a common trap is reaching for `terraform state mv`, which works imperatively but is not the recommended declarative method for configuration-driven teams. Remember the memory tip: "Moved blocks move state without moving a muscle"—they handle the remapping automatically during planning, ensuring zero downtime and preserving all existing resources.
TF-003 Interact with Terraform modules Practice Question
This TF-003 practice question tests your understanding of interact with terraform modules. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A team renamed a module from 'module.network' to 'module.vpc' in their configuration. They run 'terraform plan' and see that Terraform wants to destroy the old network resources and create new ones. They want to preserve the existing resources without downtime. What should they do?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Add a 'moved' block to the configuration to map the old module address to the new one.
Using the 'moved' block is the recommended way to refactor module names without destroying/recreating resources. Option A is wrong because 'terraform state mv' would also work but requires manual commands; 'moved' is declarative. Option B is wrong because changing the source would change the module content, not just the name. Option C is wrong because destroying and recreating causes downtime.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✓
Add a 'moved' block to the configuration to map the old module address to the new one.
Why this is correct
The 'moved' block tells Terraform to treat the renamed module as the same set of resources, preventing destroy/recreate.
Related concept
Read the scenario before looking for a memorised answer.
✗
Use 'terraform state mv' to move the resources to the new module address.
Why it's wrong here
This works but is not the best practice; the 'moved' block is declarative and preferred.
✗
Update the module source to a new version.
Why it's wrong here
Changing source may alter resources; it doesn't fix the name refactoring issue.
✗
Accept the destroy and recreate since it's the only way.
Why it's wrong here
This would cause downtime; there are better approaches.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
Use explanations to understand the rule behind the answer.
TExam Day Tips
→Underline the problem statement mentally.
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the TF-003 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
