Quick Answer
The answer is ~> 3.2.0 because the pessimistic operator with three numeric parts locks the constraint to only patch-level updates within the 3.2.x series, allowing versions like 3.2.1 or 3.2.5 but blocking any minor or major bumps. This works because Terraform interprets the tilde-greater-than symbol as “allow the rightmost specified segment to increment,” so ~> 3.2.0 permits changes only to the patch digit. On the HashiCorp Terraform Associate TF-003 exam, this question tests your understanding of version constraint syntax and the critical difference between two-part and three-part pessimistic constraints—a common trap is confusing ~> 3.2 (which allows minor updates to 3.3) with ~> 3.2.0 (which does not). To remember, think of the three-part constraint as a “patch-only cage”: the extra zero locks the minor version in place, so only the last number can move.
This TF-003 practice question tests your understanding of interact with terraform modules. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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 is using a module from the Terraform Registry and wants to ensure they always get the latest patch version of the 3.2.x series. Which version constraint should they use?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "always"
Why it matters: Absolute qualifier. An answer using 'always' is only correct if there are genuinely no exceptions — absolute statements are often wrong in networking.
~> 3.2
Why wrong: This allows minor version updates (e.g., 3.3.0), not just patches.
3.2.*
Why wrong: This is not a valid Terraform version constraint syntax.
~> 3.2.0
This allows only patch-level increments within 3.2.x (e.g., 3.2.0 to 3.2.1).
>= 3.2, < 4.0
Why wrong: This also allows minor version updates, which is broader than required.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
~> 3.2.0
Option C is correct because the pessimistic constraint operator ~> with three parts (e.g., ~> 3.2.0) allows only patch-level changes (3.2.0, 3.2.1, etc.). Option A (~> 3.2) allows minor version updates (3.3, 3.4). Option B (>= 3.2, < 4.0) also allows minor updates. Option D is invalid syntax.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
~> 3.2
Why it's wrong here
This allows minor version updates (e.g., 3.3.0), not just patches.
3.2.*
Why it's wrong here
This is not a valid Terraform version constraint syntax.
~> 3.2.0
Why this is correct
This allows only patch-level increments within 3.2.x (e.g., 3.2.0 to 3.2.1).
Clue confirmation
The clue word "always" in the question point toward this answer.
Related concept
Static NAT maps one inside address to one outside address.
>= 3.2, < 4.0
Why it's wrong here
This also allows minor version updates, which is broader than required.
Common exam traps
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Detailed technical explanation
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Real-world example
A small business has 20 workstations on the 192.168.1.0/24 network and one public IP from its ISP. The router uses PAT (NAT overload) so all 20 devices share one public address using different source ports. NAT questions test whether you understand the four address terms and which direction each translation applies.
What to study next
Review the four NAT address types (inside local, inside global, outside local, outside global), PAT port overload, and static vs dynamic NAT use cases. Then practise related TF-003 NAT questions on configuration and troubleshooting.

Same concept, more angles
These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. Which version of the module was downloaded and why?
easyWhy C: The version constraint ~> 3.0 allows any version in the 3.x range, and 3.19.0 is the latest version within that constraint at the time of init. Option B is wrong because '~> 3.0' does not allow 3.0.0 only; it allows all 3.x versions. Option C is wrong because 3.19.0 is higher than 3.0.0, but still matches. Option D is wrong because the constraint does not limit to patch updates; it allows minor updates as well (since '~> 3.0' is equivalent to '>= 3.0, < 4.0').
Variation 2. A team wants to use a networking module from the public Terraform Registry. They need to ensure they always get the latest patch version within the 1.2.x series. Which version constraint should they use in the module block?
easyWhy D: The ~> 1.2 constraint allows only patch version updates (e.g., 1.2.0 to 1.2.9), which matches the requirement. Option A is wrong because = 1.2.0 pins to an exact version, not allowing patch updates. Option C is wrong because >= 1.2.0, < 2.0.0 allows minor version updates (e.g., 1.3.0), which is too broad. Option D is wrong because >= 1.2.0 allows any version 1.2.0 or higher, including 2.0.0.
