A company is considering moving its on-premises workloads to Azure. The CFO wants to understand how Azure pricing works. Which pricing model allows them to pay only for what they use, with no upfront costs or termination fees?
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
Reserved instances
Reserved instances require a prepaid commitment for a 1- or 3-year term, providing a discount but not a pay-as-you-go model.
B
Distractor review
Spot VMs
Spot VMs offer lower cost but can be evicted by Azure when capacity is needed; they are not a consistent pay-as-you-go model.
C
Best answer
Pay-as-you-go
Pay-as-you-go charges for resources consumed (e.g., compute hours, storage) with no upfront cost or termination fee, offering full flexibility.
D
Distractor review
Hybrid Benefit
Azure Hybrid Benefit is a licensing discount program for certain Microsoft software, not a pricing model for general resource consumption.
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: Pay-as-you-go — Pay-as-you-go is the standard consumption-based pricing model where you are billed for the resources you use without any upfront commitment. Reserved instances require a one- or three-year commitment. Spot VMs offer large discounts but can be reclaimed. Hybrid Benefit allows you to use existing on-premises licenses for a discount.
