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
Rapid elasticity
Correct. The automatic scaling of VMs up and down in response to traffic spikes demonstrates rapid elasticity.
B
Distractor review
On-demand self-service
Incorrect. On-demand self-service refers to a user's ability to provision resources without human interaction, not the automatic scaling behavior.
C
Distractor review
Resource pooling
Incorrect. Resource pooling is about sharing infrastructure among multiple customers, not dynamic scaling.
D
Distractor review
Measured service
Incorrect. Measured service involves tracking usage for billing, not the ability to scale 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.
