Exam CCSP topic 1 question 398 discussion

I worry this question or answer is wrong. Thn question might originally asks for the "exception", or the answer is C. The current answer explanation shows four IaaS merits w/o the priority, whch out of three of them are in the choices. Also, in the (ISC)2 official app has a question as below, which suggest the ownership cost transfer is the best merit of the IaaS: When using an Infrastructure as a Service (IaaS) solution, what is the key benefit for the customer? (A) Scalability (B) Metered service (C) Energy and cooling efficiencies (D) Transfer of ownership cost Explanation D. The primary benefit to the customer of using Infrastructure as a Service (IaaS) is the transfer of cost of ownership. In a cloud environment, the customer uses and is billed only for what they use as opposed to the full cost of implementation, saving them a significant amount in terms of cost of ownership. While scalability, metered service, and energy and cooling efficiencies are a part of the benefit of a cloud computing environment, they are not the primary benefit or business driver behind Infrastructure as a Service (IaaS) adoption.

The answer is in correct because "metered and priced on the basis of units consumed" applies to all three cloud services not just IaaS

One of the key benefits of Infrastructure as a Service (IaaS) is that it follows a pay-as-you-go model, meaning customers are billed based on the actual resources consumed (e.g., compute, storage, and networking). This metered pricing allows for cost efficiency and flexibility, as businesses only pay for what they use. Why Not the Others? B. Increased energy and cooling system efficiencies → While cloud providers benefit from economies of scale and energy efficiency, this is not a direct benefit to the IaaS customer. C. Transferred cost of ownership → While IaaS reduces capital expenses (CapEx) by shifting infrastructure costs to operational expenses (OpEx), customers still pay for what they use. D. The ability to scale up infrastructure services based on projected usage → IaaS provides on-demand scalability, but scaling is based on actual demand, not just projections.

D. The ability to scale up infrastructure services based on projected usage IaaS provides customers with scalable computing resources over the internet. This scalability is a significant advantage, allowing businesses to quickly adjust their infrastructure to meet changing demands without having to invest in physical hardware. This flexibility supports dynamic workloads and helps organizations optimize their resource usage efficiently.

The answer is C. Transfered cost of ownership. I saw this question in the CCSP ISC2 official app (LearnZapp) and the answer was C.

D: The ability to scale up infrastructure services based on projected usage

answer is correct Cost is alway #1 concern

It has to be C. That is the main benefit. You get control over infra without the cost of owning and maintaining infra.

Clearly D is the correct answer here
