A company subscribes to a SaaS-based customer relationship management (CRM) application hosted in the cloud. The CRM provider manages the application, runtime, and infrastructure. The company's employees access the CRM via a web browser. According to the shared responsibility model, which security responsibility belongs solely to the company?
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.
Distractor review
Patching the underlying operating system of the CRM servers.
In a SaaS model, the cloud provider is responsible for patching the operating system and infrastructure. The customer does not have access to the underlying servers, so this responsibility belongs to the provider.
Distractor review
Managing network access controls to the CRM application.
For SaaS, the provider typically manages network-level controls, such as firewalls and network segmentation, as part of securing the application infrastructure. The customer may configure application-level settings but not the underlying network.
Best answer
Safeguarding the company's customer data and user identities.
The customer is always responsible for their own data, including data classification, encryption, and access management. In SaaS, the provider does not have insight into which users should have access; the customer must manage identities and protect data.
Distractor review
Ensuring physical security of the data centers hosting the CRM.
Physical security of data centers, including access controls, surveillance, and environmental protections, is solely the responsibility of the cloud provider regardless of the service model.
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: Safeguarding the company's customer data and user identities. — In the shared responsibility model, responsibilities vary by service model. For SaaS, the cloud provider is responsible for the underlying infrastructure, operating system, application platform, and application itself, including applying security patches and managing network controls. The customer retains responsibility for securing their own data, managing user access and identities, and ensuring that their usage complies with applicable laws and policies. Physical security of data centers is always the provider's responsibility. Therefore, safeguarding customer data and user identities is exclusively the customer's responsibility.
