Exam CCSP topic 1 question 361 discussion

It is A. Interoperability. I was leaning towards portability as well but this requirement - "save costs by reusing components" - is provided by interoperability, so that seems to be the correct answer.

"The committee is concerned with getting locked into a single cloud provider and has flagged the ability to easily move between cloud providers as a top priority" - Shouldn't it be portability?!

Portability is the cross-cutting aspect of cloud computing that ensures an organization can easily move applications, workloads, and data between different cloud providers without excessive reconfiguration, vendor lock-in, or dependency on proprietary services. It also supports cost savings by enabling reuse of components across cloud environments. Why Not the Others? A. Interoperability → Focuses on ensuring different cloud systems and services work together, but does not specifically address switching providers. B. Resiliency → Ensures cloud services remain available and recoverable during failures but is unrelated to vendor lock-in. C. Scalability → Addresses the ability to adjust resources dynamically, not the ability to move between cloud providers.

Interoperability: It involves the ability to transfer data between different cloud services without losing its integrity or requiring significant reformatting.

Interoperability all the way. It says reuse.

D: Portability. Data portability allows users to move data from one company to another, helping to reduce switching costs and providing rival firms with access to valuable customer data. Interoperability allows two or more technical systems to exchange data interactively.

D: Portability

Correct answer is D, Portability folks. Interoperability is the ability of a system or application to reuse components. This allows organizations to avoid particular ties to vendors or other systems for the components or functions of their own systems and applications. This can also be related to the use of standardized data structures and formats to avoid vendor lock-in. Source: CCSP - All In One Exam Guide, 2nd Edition, page 426.

It's D, due to this statement "easily move between cloud providers as a top priority"

also, answer from another question: Portability is the ability for a service or system to easily move among different cloud providers. This is essential for using a cloud solution for BCDR because vendor lock-in would inhibit easily moving and setting up services in the event of a disaster, or it would necessitate a large number of configuration or component changes to implement. Interoperability, or the ability to reuse components for other services or systems, would not be an important factor for BCDR.

"It also wants to save costs by reusing components." This is the only part of the question I think would relate to Interoperability, the rest of the concern and the biggest is not being locked in.

"easily move between cloud providers as a top priority" Portability for me

Interoperability = Ability to share data between tools and cloud environment /on-prem environment. Portability = Movement to and from cloud as well as between CSPs Question concerns about moving between CSPs and not about co-existing with another CSP or On-prem. Main focus of question is being able to move to different CSP. You will need to address portability for this. Based on these definitions from CBK reference , the answer is Portability (D) Interoperability is luxury where as Portability is the necessity for moving between csps (the way I see)

There's two sentences in the stem. The first describes portability, the second interoperability. Pick your poison.

It is a very easy question, no need to struggle with (A)

Top priority is ability to move to different cloud , so answer is Portability.

Considering the top priority is the ability to move, I would still select portability.
