Explanation:
To monitor data in use, the DLP solution's optimal location would be on the user's client or workstation, where the data would be used or processed, and where it would be most vulnerable to access or exposure. The network perimeter is most appropriate for data in transit, and an application server would serve as middle stage between data at rest and data in use, but is a less correct answer than a user's client. A database server would be an example of a location appropriate for monitoring data at rest.

Auditing involves reports and evidence that show user activity, compliance with controls and regulations, the systems and processes that run and what they do, as well as information and data access and modification records. A cloud environment adds additional complexity to traditional audits because the cloud customer will not have the same level of access to systems and data as they would in a traditional data center.

Explanation
Volume storage is allocated and mounted as a virtual hard drive within IaaS implementations, and it can be maintained and used the same way a traditional file system can. Object storage uses a flat structure on remote services that is accessed via opaque descriptors, structured storage resembles database storage, and unstructured storage is used to hold auxiliary files in conjunction with applications hosted within a PaaS implementation.

The Simple Object Access Protocol (SOAP) protocol only supports the Extensible Markup Language (XML) data format. Although the other options are all data formats or data structures, they are not supported by SOAP.
