During the data-in-use state, the information has already been accessed from storage and transmitted to the service, so reliance on a technology such as digital signatures is imperative to ensure security and complement the security methods used during previous states. Data in transit relies on technologies such as TLS to encrypt network transmission of packets for security. Data at rest primarily uses encryption for stored file objects.
Archived data would be the same as data at rest.

Anonymization is a type of masking, where indirect identifiers are removed from a data set to prevent the mapping back of data to an individual. Although masking refers to the overall approach of covering sensitive data, anonymization is the best answer here because it is more specific to exactly what is being asked.
Tokenization involves the replacement of sensitive data with a key value that can be matched back to the real value. However, it is not focused on indirect identifiers or preventing the matching to an individual. Encryption refers to the overall process of protecting data via key pairs and protecting confidentiality.

Explanation:
The CPU and memory resources of an environment together comprise its "computing" resources. Cloud environments, especially public clouds, are enormous pools of resources for computing and are typically divided among a large number of customers with constantly changing needs and demands. Although storage and networking are core components of a cloud environment, they do not comprise its computing core. Software, much like within a traditional data center, is highly subjective based on the application, system, service, or cloud computing model used; however, it is not one of the core cloud components.
