Question

which azure cloud service model is used when you need one or more powerful virtual machines (vms) for a temporary period? a platform-as-a-service (paas) b infrastructure-as-a-service (iaas) c software-as-a-service (saas) d none of these

Explanation:

To determine the correct Azure cloud service model, we analyze each option:

• Option A (PaaS): PaaS provides a platform for developing, running, and managing applications without managing the underlying infrastructure. It does not focus on providing virtual machines directly for temporary use.
• Option B (IaaS): IaaS offers virtualized computing resources over the internet, including virtual machines. When you need one or more powerful VMs for a temporary period, IaaS is suitable as it allows you to rent and use infrastructure components like VMs on a temporary basis.
• Option C (SaaS): SaaS delivers software applications over the internet on a subscription basis. It does not involve providing virtual machines for infrastructure - related use.
• Option D: Since Option B is correct, this option is invalid.

Answer:

B. Infrastructure - as - a - service (IaaS)
