Microsoft Certified: Azure Fundamentals (AZ-900) Practice Exam

What is the advantage of moving your company's infrastructure to Azure by using a public cloud model?

1. There are no capital expenditure (CapEx) costs.

2. There are no operational expenditure costs (OpEx) costs.

3. The company has complete control of resources that are used by the operating system.

4. Legacy applications are easier to support.

The correct answer is: There are no capital expenditure (CapEx) costs.

Choosing to move your company's infrastructure to Azure utilizing a public cloud model presents several advantages, one of which is the elimination of capital expenditure (CapEx) costs. In a public cloud model, organizations can leverage resources as needed without the upfront costs associated with purchasing and maintaining physical hardware and infrastructure. Instead of investing in servers, storage, and networking equipment, companies can pay for the services they utilize on a consumption basis, allowing for greater flexibility and the ability to allocate funds to other areas of the business. This model helps improve cash flow and enables organizations to scale resources up or down depending on demand, without the burden of large capital investments. By converting fixed costs into variable costs, businesses can more easily adapt their IT spending in response to changing needs, leading to greater financial efficiency. The other options generally reflect aspects of resource management or control that are not characteristic of a public cloud model. For instance, while operational expenditure costs may still exist in any IT model, CapEx costs are particularly reduced in a public cloud setup. Similarly, complete control of resources is more aligned with private clouds or on-premises solutions, and the challenges of supporting legacy applications can vary based on a range of factors rather than being inherently easier in the public cloud.
