Certified Cloud Security Professional (CCSP) — Question 506

A main objective for an organization when utilizing cloud services is to avoid vendor lock-in so as to ensure flexibility and maintain independence.
Which core concept of cloud computing is most related to vendor lock-in?

Answer options

• A. Scalability
• B. Interoperability
• C. Portability
• D. Reversibility

Correct answer: C

Explanation

Portability is the core concept that addresses vendor lock-in as it allows applications and data to move easily between different cloud environments or providers. Scalability refers to the ability to grow resources as needed, interoperability deals with how different systems work together, and reversibility pertains to the process of transitioning back to on-premises solutions, which are less directly linked to avoiding vendor lock-in.
