Which of the following risks is associated with cloud computing?

The correct choice reflects a significant concern in cloud computing environments: enhanced internal personnel risks. In any organization, human factors significantly impact security, and this is especially true in cloud environments where employees may have access to sensitive data and services. Cloud computing often involves multiple users and layers of access, making it crucial for organizations to manage credentials and permissions meticulously.

As personnel have varying degrees of access, the risk of internal threats arises. This can include intentional misuses of access, such as data theft or unauthorized data manipulation, as well as unintentional errors that stem from a lack of training or awareness regarding security protocols. Internal personnel risks can lead to breaches or data leaks that affect the organization's reputation and compliance with regulations.

In contrast, other options do not accurately represent common risks associated with cloud computing. The physical office space would typically reduce, not increase, with cloud adoption as services migrate online. Greater control over hardware is often not a benefit of cloud adoption because companies usually rely on third-party providers to manage their hardware. Finally, lower data redundancy contradicts the principles of cloud technology, which often aims to improve redundancy and availability through distributed architectures.
