Which of the following actions will NOT make data part of the create phase of the cloud data
lifecycle?
A. Modify data
B. Modify metadata
C. New data
D. Import data
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?
A. XML
B. XSLT
C. JSON
D. SAML

,Page 2 of 157
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?
A. Structured
B. Unstructured
C. Volume
D. Object
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?
A. Acceleration
B. Caching
C. Redundancy
D. Encryption
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.
The management plane is use to administer a cloud environment and perform administrative
tasks across a variety of systems, but most specifically it's used with the hypervisors.
What does the management plane typically leverage for this orchestration?
A. APIs
B. Scripts
C. TLS
D. XML
The management plane uses APIs to execute remote calls across the cloud environment to
various management systems, especially hypervisors. This allows a centralized administrative
interface, often a web portal, to orchestrate tasks throughout an enterprise. Scripts may be
utilized to execute API calls, but they are not used directly to interact with systems. XML is used
for data encoding and transmission, but not for executing remote calls. TLS is used to encrypt
communications and may be used with API calls, but it is not the actual process for executing
commands.
When dealing with PII, which category pertains to those requirements that can carry legal
sanctions or penalties for failure to adequately safeguard the data and address compliance
requirements?
A. Contractual
B. Jurisdictional
C. Regulated
D. Legal
3
, Page 4 of 157
Regulated PII pertains to data that is outlined in law and regulations. Violations of the
requirements for the protection of regulated PII can carry legal sanctions or penalties.
Contractual PII involves required data protection that is determined by the actual service
contract between the cloud provider and cloud customer, rather than outlined by law.
Violations of the provisions of contractual PII carry potential financial or contractual
implications, but not legal sanctions. Legal and jurisdictional are similar terms to regulated, but
neither is the official term used.
Although the united states does not have a single, comprehensive privacy and regulatory
framework, a number of specific regulations pertain to types of data or populations.
Which of the following is NOT a regulatory system from the United States federal
government?
A. HIPAA
B. SOX
C. FISMA
D. PCI DSS
The Payment Card Industry Data Security Standard (PCI DSS) pertains to organizations that
handle credit card transactions and is an industry-regulatory standard, not a governmental one.
The Sarbanes-Oxley Act (SOX) was passed in 2002 and pertains to financial records and
reporting, as well as transparency requirements for shareholders and other stakeholders. The
Health Insurance and Portability Act (HIPAA) was passed in 1996 and pertains to data privacy
and security for medical records. FISMA refers to the Federal Information Security Management
Act of 2002 and pertains to the protection of all US federal government IT systems, with the
exception of national security systems.
