A sales team wants to build a custom inventory tracking application with minimal code. They need a cloud-based database that can securely store structured data and integrate with the low-code app builder. Which Microsoft 365 service should they use as the database backend?
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Distractor review
Microsoft Lists
Microsoft Lists is suitable for simple list tracking but does not offer the relational database capabilities, advanced security, and low-code integration that Dataverse provides for custom business apps.
B
Distractor review
Power Apps
Power Apps is the low-code application platform used to build the app, but it requires a data source (like Dataverse) to store and retrieve data.
C
Best answer
Microsoft Dataverse
Dataverse provides a secure, scalable database that stores structured business data. It is designed to be the data backend for Power Apps, making it the correct choice for this scenario.
D
Distractor review
Power Automate
Power Automate is a workflow automation tool, not a database. It can act on data but does not store it.
Common exam trap
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.
Technical deep dive
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.

FAQ
Questions learners often ask
What does this MS-900 question test?
Static NAT maps one inside address to one outside address.
What is the correct answer to this question?
The correct answer is: Microsoft Dataverse — Microsoft Dataverse (formerly Common Data Service) is the cloud-scale database that provides secure, structured data storage for business applications built with Power Apps. It natively integrates with Power Apps, Power Automate, and other Microsoft 365 services. Microsoft Lists is a simpler list-based solution but lacks the relational database capabilities needed for a robust custom app. Power Apps is the app platform itself, not the database. Power Automate is for workflow automation.
