This PCA practice question tests your understanding of designing for security and compliance. 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.
An organization needs to run workloads that are subject to ITAR (International Traffic in Arms Regulations) in Google Cloud. Which region should they use to ensure compliance with ITAR requirements?
europe-west1
Why wrong: europe-west1 is not in the US, not ITAR-compliant.
us-central1
Why wrong: us-central1 is not ITAR-compliant.
us-military-east4
us-military-east4 is part of Assured Workloads for Government and supports ITAR.
us-east1
Why wrong: us-east1 is not ITAR-compliant.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
us-military-east4
Assured Workloads for Government provides controlled regions that are compliant with ITAR. The us-central1 region is not ITAR-compliant. The us-military regions (e.g., us-military-east4) are part of Assured Workloads for Government and support ITAR.
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.
europe-west1
Why it's wrong here
europe-west1 is not in the US, not ITAR-compliant.
us-central1
Why it's wrong here
us-central1 is not ITAR-compliant.
us-military-east4
Why this is correct
us-military-east4 is part of Assured Workloads for Government and supports ITAR.
Related concept
Static NAT maps one inside address to one outside address.
us-east1
Why it's wrong here
us-east1 is not ITAR-compliant.
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 cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
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 PCA NAT questions on configuration and troubleshooting.
