TF-003 Use Terraform outside the core workflow Practice Question
This TF-003 practice question tests your understanding of use terraform outside the core workflow. 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.
An organization uses Terraform Cloud with a VCS-backed workspace connected to a GitHub repository. They want to trigger a speculative plan without creating a run (i.e., without costing compute resources or being displayed in the workspace). Which approach is appropriate?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Run 'terraform plan' from a local CLI configured with the same workspace and a remote backend.
Option B is correct because running 'terraform plan' from a local CLI that is configured with the same workspace and a remote backend will produce a speculative plan that is displayed locally and does not create a run in Terraform Cloud by default. Option A is wrong because VCS pushes create formal runs. Option C is wrong because the API creates runs. Option D is wrong because there is no built-in '--speculative' flag.
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
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Push a new commit to the GitHub repository with a 'plan' label.
Why it's wrong here
This would trigger a run in Terraform Cloud, not a speculative plan.
✗
Use the 'plan -out' flag with a special path to avoid creating a run.
Why it's wrong here
'-out' does not affect run creation.
✗
Use the Terraform Cloud API to queue a plan with 'auto-apply' disabled.
Why it's wrong here
This creates a formal run in Terraform Cloud.
✓
Run 'terraform plan' from a local CLI configured with the same workspace and a remote backend.
Why this is correct
Local CLI plans do not create runs in Terraform Cloud by default.
Related concept
Static NAT maps one inside address to one outside address.
Common exam traps
Common exam trap: NAT rules depend on direction and matching traffic
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
How to think about this question
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.
KKey Concepts to Remember
Static NAT maps one inside address to one outside address.
PAT allows many inside hosts to share one public address using ports.
Inside local and inside global describe the private and translated addresses.
NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
→Identify inside and outside interfaces first.
→Check whether the scenario needs static NAT, dynamic NAT or PAT.
→Do not confuse NAT matching ACLs with normal packet-filtering intent.
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
How this comes up in practice
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
Got this wrong? Here's your next step.
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.
