Which of the following actions will NOT make data part of the create phase of the cloud data lifecycle?
Answer(s): B
Modifying the metadata does not change the actual data. Although this initial phase is called "create," it can also refer to modification. In essence, any time data is considered "new," it is in the create phase. This can come from data that is newly created, data that is imported into a system and is new to that system, or data that is already present and is modified into a new form or value.
Most APIs will support a variety of different data formats or structures.However, the SOAP API will only support which one of the following data formats?
Answer(s): A
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.
Which cloud storage type is typically used to house virtual machine images that are used throughout the environment?
Answer(s): D
Object storage is typically used to house virtual machine images because it is independent from other systems and is focused solely on storage. It is also the most appropriate for handling large individual files. Volume storage, because it is allocated to a specific host, would not be appropriate for the storing of virtual images.Structured and unstructured are storage types specific to PaaS and would not be used for storing items used throughout a cloud environment.
With an API, various features and optimizations are highly desirable to scalability, reliability, and security. What does the REST API support that the SOAP API does NOT support?
The Simple Object Access Protocol (SOAP) does not support caching, whereas the Representational State Transfer (REST) API does. The other options are all capabilities that are either not supported by SOAP or not supported by any API and must be provided by external features.
Although much of the attention given to data security is focused on keeping data private and only accessible by authorized individuals, of equal importance is the trustworthiness of the data.Which concept encapsulates this?
Integrity refers to the trustworthiness of data and whether its format and values are true and have not been corrupted or otherwise altered through unauthorized means. Confidentiality refers to keeping data from being access or viewed by unauthorized parties. Accessibility means that data is available and ready when needed by a user or service. Validity can mean a variety of things that are somewhat similar to integrity, but it's not the most appropriate answer in this case.
