- A
Enable Microsoft Purview Data Loss Prevention for Azure DevOps, which automatically scans and blocks pushes containing sensitive data
This is the native Microsoft solution that meets all requirements.
- B
Configure a branch policy in Azure Repos that runs a custom Azure Function via a service hook when a push occurs, and the function uses Purview APIs to scan the commit
Why wrong: This is overly complex and not a native solution.
- C
Install a third-party extension from Azure DevOps Marketplace that provides content scanning and configure it to block pushes
Why wrong: Third-party extensions may not integrate with Purview and may not be as reliable.
- D
Use GitHub Advanced Security secret scanning for Azure Repos, and configure a webhook to notify the security team
Why wrong: GitHub Advanced Security is not available for Azure Repos.
AZ-400 Develop a security and compliance plan Practice Question
This AZ-400 practice question tests your understanding of develop a security and compliance plan. 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.
Your organization uses Microsoft Purview Data Loss Prevention (DLP) to protect sensitive data in Azure DevOps repositories. The compliance team has identified that source code containing credit card numbers (PCI data) was accidentally committed to a public repository. You need to implement a solution that meets the following requirements: (1) Automatically scan all new commits in Azure Repos for sensitive data types like credit card numbers. (2) If sensitive data is detected, automatically block the push and notify the security team. (3) The solution must be integrated with Microsoft Purview and Azure DevOps.
Option A: Configure a branch policy in Azure Repos that runs a custom Azure Function via a service hook when a push occurs, and the function uses Purview APIs to scan the commit.
Option B: Enable Microsoft Purview Data Loss Prevention for Azure DevOps, which automatically scans and blocks pushes containing sensitive data.
Option C: Use GitHub Advanced Security secret scanning for Azure Repos, and configure a webhook to notify the security team.
Option D: Install a third-party extension from Azure DevOps Marketplace that provides content scanning and configure it to block pushes.

Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Enable Microsoft Purview Data Loss Prevention for Azure DevOps, which automatically scans and blocks pushes containing sensitive data
Option B is correct. Microsoft Purview DLP for Azure DevOps (in preview/GA) provides native scanning and blocking of sensitive data in commits. Option A is complex and not native. Option C is for GitHub, not Azure Repos. Option D might not be native and may not integrate with Purview.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.

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 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.
