Which of the following is NOT a characteristic of public cloud services?

Public cloud services are designed to be accessible and available to multiple users and organizations through the Internet. One of their defining characteristics is that they are managed by third-party providers who take care of the hardware, software, and maintenance, allowing businesses to focus on their core functions without worrying about underlying infrastructure.

Scalability and elasticity are also key attributes of public cloud services, enabling users to adjust their resources up or down based on demand without needing to make physical hardware changes. This flexibility allows organizations to optimize performance and costs effectively.

Conversely, the concept of "exclusive use by a single organization" does not align with the public cloud model. Public clouds are shared environments where multiple tenants use the same infrastructure. This sharing allows for cost-efficiency and resource optimization, making public cloud services appealing for a wide range of users.

Thus, the answer points out a fundamental misunderstanding of how public cloud services operate in terms of access and ownership.
