What type of storage allows users to access their data from various remote locations?

The correct choice is mobile cloud storage, which is designed specifically to enable users to access their data from multiple remote locations. This type of storage leverages cloud computing technology, allowing users to store data in a centralized location on the internet. As a result, users can access their files from any device with an internet connection, regardless of geographical location. This convenience is particularly important in today's mobile and remote work environments, where users require flexible access to their data at any time and from any place.

In contrast, layered defenses refer to a security strategy that employs multiple protective measures to secure data, rather than being focused on accessibility. The management plane pertains to the cloud service management aspect, which deals with the operations and maintenance of cloud resources, while key risk indicators are metrics used to assess potential risks within an organization. These other options do not specifically address the accessibility of data from various remote locations.
