A company migrates its database to a cloud service where the provider manages the database engine, patching, backups, and replication. The customer only manages the data and schema. Which cloud service model is this?
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
Infrastructure as a Service (IaaS)
With IaaS, the customer would be responsible for managing the operating system, database engine, and patching.
B
Best answer
Platform as a Service (PaaS)
PaaS provides a managed platform where the provider handles the database engine, patches, backups, and replication; the customer focuses on data and schema.
C
Distractor review
Software as a Service (SaaS)
SaaS delivers a complete application managed by the provider. The customer would not manage the database schema directly; they use the application interface.
D
Distractor review
On-premises
On-premises means the company owns and manages all hardware and software, which is not the case here.
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: Platform as a Service (PaaS) — This scenario describes Platform as a Service (PaaS), where the provider manages the underlying infrastructure, runtime, and database engine, while the customer manages only the data and schema. IaaS would require the customer to manage the database engine, and SaaS would involve a fully managed application, not just a database.
