Question 1hardmultiple choice
Full question →hardmultiple choiceObjective-mapped
A company is deploying a cloud solution where they have the ability to quickly scale up resources during peak demand and scale down during off-peak hours, paying only for what they use. They also need the provider to automatically manage the underlying platform, including patching the operating system. Which combination of cloud characteristics and service model best describes this scenario?
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
Best answer
Elasticity and PaaS
Elasticity allows rapid scaling based on demand; PaaS manages the OS and platform, matching the provider responsibilities described.
B
Distractor review
Scalability and IaaS
Scalability is a broader term; IaaS requires the customer to manage the OS, not the provider.
C
Distractor review
Rapid elasticity and SaaS
SaaS provides fully managed applications, but the customer typically does not control scaling; also SaaS does not expose OS patching to the customer.
D
Distractor review
Measured service and PaaS
Measured service refers to metering and billing for usage, not automatically scaling resources or managing the OS.
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: Elasticity and PaaS — Elasticity is the ability to automatically scale resources up and down based on demand, a key characteristic of cloud computing. Platform as a Service (PaaS) offloads management of the operating system and runtime to the provider, allowing customers to focus on applications. The described scenario combines both: automatic scaling (elasticity) and provider-managed OS (PaaS).
