Which option describes dedicated hosting?

Dedicated hosting refers to a service where a client is provided with an entire server that is not shared with anyone else. This means that the client has full control over the server, including its configuration, software, and security measures. Since all resources of that server are exclusively allocated to that client, it enables them to customize the server environment to suit their specific needs, which is particularly beneficial for businesses that require high performance, flexibility, and security.

The other options do not accurately describe dedicated hosting. Shared resources indicate that multiple clients use the same server resources, which is characteristic of shared hosting rather than dedicated hosting. Utilizing a cloud provider typically involves virtual environments where resources can be dynamically allocated, differing from the fixed and sole ownership of a dedicated server. Lastly, management by an external firm is more aligned with managed hosting services, where the hosting provider takes care of server management tasks, which can happen in both shared and dedicated environments but does not define dedicated hosting itself.
