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

Resource pooling

Correct. Resource pooling allows the provider to aggregate physical resources and serve multiple tenants (multi-tenancy).

B

Distractor review

On-demand self-service

Incorrect. On-demand self-service means users can provision resources without provider interaction, not the sharing of infrastructure.

C

Distractor review

Rapid elasticity

Incorrect. Rapid elasticity refers to automatic scaling of resources, not the multi-tenant sharing of infrastructure.

D

Distractor review

Measured service

Incorrect. Measured service is about monitoring and billing for usage, not about sharing physical resources.

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: Resource pooling — Resource pooling is the ability of a cloud provider to serve multiple customers from the same physical infrastructure, using virtualization to isolate them securely. This enables economies of scale and dynamic allocation. On-demand self-service is about user provisioning without interaction. Rapid elasticity is about scaling. Measured service is about metering usage.
