WGU D772 PRACTICE EXAMINATION 2026
QUESTIONS WITH ANSWERS GRADED A+
◍ waterfall model (SDLC).
Answer: Where each stage must be completed before moving on to the next
stage; slow application development; used when system requirements are
clearly documented and unlikely to change.
◍ Agile development (SDLC).
Answer: encourages adaptive planning and development, fast delivery,
continuous improvement, and flexibility in response to change. (interactive)
◍ Electronic Data Interchange (EDI).
Answer: An automatic electronic exchange of data and documents from one
computer system to another through a standardized messaging format that
does not require human intervention.
◍ Data Governance.
Answer: Concerned with the management of data, including maximizing
quality through effective utilization, availability, and protection.
◍ Perceived Lack of Anonymity.
Answer: Type of response bias which occurs when the responder fears
giving an honest answer might negatively affect them, leading to dishonest
or misleading responses.
◍ Quantitative Variable.
Answer: Data based on numerical measurement.
◍ Prototyping Software Development Method.
Answer: User basic requirements, development of prototype, using
prototype, and revising prototype
◍ Group Decision Support System (GDSS).
, Answer: n interactive computer based system that facilitates a number of
decision-makers (working together in a group) in finding solutions to
problems that are unstructured in nature; enables remote collaboration.
◍ Digital Millennium Copyright Act (DMCA).
Answer: A United States copyright law created to prosecute the production
and dissemination of technology, devices, or services that control access to
copyrighted works.
◍ Strategic information system.
Answer: provide tools used by an organization to accomplish specific tasks
to gain competitive advantage.
◍ Observational Study.
Answer: When researchers observe and record data on variables as they
naturally occur, without any intervention or manipulation.
◍ Query Language.
Answer: Provides instructions and procedures to retrieve data from a
database.
◍ The Three Norms in Normalization.
Answer: 1NF, 2NF, 3NF
◍ Information.
Answer: Data that has been organized in a meaningful manner.
◍ Radio Frequency Survey.
Answer: Used to determine wireless access point locations based upon
signal strength.
◍ Modular Design.
Answer: a design approach that subdivides a system into smaller parts called
modules or skids, that can be independently created and then used in
different systems.
◍ Multinational.
Answer: an organization that owns or controls production of goods or
, services in one or more countries other than their home country.
◍ Telecommunications Network.
Answer: Enables the exchange of information between end users across
nodes and links.
◍ Secondary storage.
Answer: accessed only through a system's input/output bus and is generally
several orders of magnitude slower than primary storage
technologiesRemovable media, such as magnetic floppy disks, optical discs
(CDs & DVDs), and USB flash drives
◍ Fourth generation computer languages (4GL).
Answer: software tools that help reduce the amount of procedural
knowledge that is needed about how computers operate and lets end users
create programs as needed; SQL is a 4GL.
◍ Data mining.
Answer: process of identifying hidden patterns and relationships in
structured databases and applying rules to that data in order to predict future
behavior.
◍ Knowledge.
Answer: The practical application of information.
◍ Horizontal Application.
Answer: Software that provides solutions based upon the common needs of
many businesses.
◍ IPv6.
Answer: The latest IP iteration, it was developed to increase the number of
unique IP addresses, as each device that connects to the Internet needs its
own IP address and there were not enough to accommodate future devices.
◍ Third generation computer languages (3GLs).
Answer: high-level programming languages such as FORTRAN, COBOL,
C, Java, C++, and C#
