A company uses a cloud service where they pay only for the compute hours their virtual machines run. They can increase or decrease the number of VMs instantly based on demand. Which two cloud computing characteristics are demonstrated? (Choose two.)

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

On-demand self-service

This characteristic allows users to provision resources without human interaction. While present in most cloud services, it is not specifically demonstrated by paying for hours used and scaling on demand.

B

Best answer

Rapid elasticity

The ability to quickly increase or decrease the number of VMs based on demand is a direct example of rapid elasticity.

C

Best answer

Measured service

Paying only for the compute hours used is an example of measured service, where usage is metered and billed accordingly.

D

Distractor review

Resource pooling

Resource pooling refers to the provider's multi-tenant model where resources are shared among many customers. This is not evident from the scenario.

Common exam trap

Common exam trap: answer the scenario, not the keyword

Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.

Technical deep dive

How to think about this question

This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.

KKey Concepts to Remember

  • Read the scenario before looking for a memorised answer.
  • Find the constraint that changes the correct option.
  • Eliminate answers that are true in general but not in this case.
  • Use explanations to understand the rule behind the answer.

TExam Day Tips

  • Underline the problem statement mentally.
  • Watch for words such as best, first, most likely and least administrative effort.
  • Review why wrong options are wrong, not only why the correct option is correct.

FAQ

Questions learners often ask

What does this MS-900 question test?

Read the scenario before looking for a memorised answer.

What is the correct answer to this question?

The correct answer is: Rapid elasticity — The scenario shows rapid elasticity (quick scaling of resources) and measured service (pay-per-use metering). On-demand self-service and resource pooling are also cloud characteristics but not directly illustrated here.
