Which of the following is an advantage of using Cloud Storage?

The advantage of using Cloud Storage that stands out is scalability. This means that users can easily adjust their storage capacity according to their current needs without the need for significant investments in physical hardware or infrastructure.

With cloud storage, individuals and organizations can start with a small amount of storage and increase it as their data requirements grow, all with relative ease. This flexibility allows for efficient resource management and the ability to respond quickly to changing demands. As businesses expand or as users accumulate more data, they can seamlessly scale up their storage solutions without disruption.

In contrast, the other options present limitations: high costs do not align with the typical operational benefits of cloud solutions, limited access would defeat the purpose of cloud storage as it is designed to be accessed from various devices anywhere with an internet connection, and slow retrieval times negatively impact performance and usability, which are key concerns for cloud storage users. Thus, scalability is a vital benefit, enabling dynamic adjustment to storage needs.
