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?

What is the correct answer to this question?
The correct answer is: Managing user access and authentication — In the PaaS model, the cloud provider is responsible for the underlying infrastructure, operating system, and virtualization. The customer is responsible for managing their data, including user access and authentication. Thus, managing user access is the customer's responsibility. Patching the OS, maintaining physical hardware, and managing the virtualization layer are handled by the provider.
