Full question →mediummultiple choiceObjective-mapped
A company is migrating its customer relationship management (CRM) system to a Software as a Service (SaaS) provider. The provider manages the application, runtime, middleware, and infrastructure. The company's IT security team is concerned about who is responsible for protecting the company's data and managing user access. Based on the shared responsibility model for cloud computing, which statement is correct?
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
The SaaS provider is responsible for everything, including data classification and user access control.
This is incorrect. The SaaS provider does not manage the customer's data classification or access control. The customer retains responsibility for its own data and who has access.
B
Distractor review
The company is responsible for the security of the application itself, including patching vulnerabilities in the CRM software.
This is incorrect. In SaaS, the provider is responsible for patching and securing the application. The customer does not have access to the underlying application code or runtime to perform such tasks.
C
Best answer
The company is responsible for managing user access and protecting their own data within the SaaS application.
This is correct. Under the shared responsibility model for SaaS, the customer manages user identities, data classification, and access control. The provider secures the platform and infrastructure, but the customer must ensure only authorized users access the data and that data is handled appropriately.
D
Distractor review
The SaaS provider is responsible for physical security of data centers, and the company is responsible for patching the operating system of the servers hosting the CRM.
This is incorrect. While the provider does handle physical security, patching the operating system is also the provider's responsibility in a SaaS model. The customer does not manage the OS at all.
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 AZ-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: The company is responsible for managing user access and protecting their own data within the SaaS application. — In the shared responsibility model for SaaS, the cloud provider is responsible for the security of the infrastructure, operating system, and application platform. The customer retains responsibility for the security of their data, managing user identities and access policies, and ensuring that the data is classified and protected according to their own compliance requirements. This division ensures that each party focuses on what they control directly.
