Annabeth has been using a public cloud to store and access her documents. Which drawback of a public cloud should she be aware of

Possible security compromise

Explanation:

Annabeth is storing her documents on public cloud as against a local data store. While doing so she is exposing herself to a possible security risk where access to her documents can be compromised to unintended parties if the security infrastructure of the cloud service provider is not sufficiently robust. The issue is more pronounced in cloud because the content resides on public infrastructure where access attempt can be made by anyone.

Answer: Security

Explanation: While Public Clouds, from credible providers, are more secure than most SME IT infrastructures, there is a trade-off. First, you can only customize security factors at the operating system level - security at the physical level is under the purview of your supplier. Second, Public Cloud servers are, by default, visible internet-wide. This has been shown to lead to increased levels of remote scanning for vulnerabilities. Securing your server at the OS level is therefore essential.
