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
Physical security of the datacenter
Physical security of the datacenter is the responsibility of the cloud provider (Microsoft), not the customer.
B
Best answer
Applying security updates to the guest operating system
The customer is responsible for securing everything inside the VM, including the guest OS. This includes applying security updates and patches.
C
Distractor review
Maintaining the hypervisor
The hypervisor is part of the virtualization layer managed by the cloud provider. The customer has no access or responsibility for it.
D
Distractor review
Power and cooling infrastructure
Power and cooling are environmental controls provided and maintained by the cloud provider as part of the physical data center operations.
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 SC-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: Applying security updates to the guest operating system — In the IaaS model, the cloud provider is responsible for the physical security of the datacenter, the underlying hardware, the hypervisor, and environmental controls like power and cooling. The customer is responsible for securing the guest operating system, including applying patches, configuring firewalls, and managing the applications and data running on the VM.
