Course/Program: WGU D278 — Scripting and Programming –
Foundations
Field of Study: Programming Fundamentals, Scripting, Algorithms,
Software Development
Level: Undergraduate, Computer Science, Software Development,
Information Technology
Edition: 2026–2027
Introduction
This comprehensive practice examination is designed for WGU students
preparing for the D278 Scripting and Programming – Foundations
objective assessment. It contains 100 advanced multiple-choice
questions covering foundational programming concepts including
algorithms, pseudocode, flowcharts, variables, data types, expressions,
decision and loop structures, functions, arrays, object-oriented
programming basics, debugging, and software development principles.
Each question reflects real-world programming scenarios and current
industry practices, with detailed rationales to reinforce understanding of
core scripting and programming concepts. Use this document to assess
readiness, identify knowledge gaps, and strengthen preparation for the
2026–2027 assessment cycle. All questions are original practice items
and are not from actual WGU exams.

1.
Which of the following best defines an algorithm?
A) A programming language
B) A step-by-step procedure or set of instructions to solve a problem
C) A type of computer hardware
D) An error in a program
Correct Answer: B
An algorithm is a finite, ordered sequence of well-defined instructions
used to solve a problem or perform a computation. It is independent of
any programming language and is fundamental to programming.
2.
Which of the following is a characteristic of a good algorithm?
A) It is ambiguous and open-ended
B) It is finite, clear, and produces correct output for all valid inputs
,C) It depends on a specific programming language
D) It cannot be represented visually
Correct Answer: B
A good algorithm is unambiguous, finite, effective, and correct. It should
produce the expected output for all valid inputs and eventually
terminate. It is language-independent and can be represented using
pseudocode or flowcharts.
3.
What is pseudocode?
A) A high-level programming language
B) A textual, informal way of describing an algorithm using natural
language and programming-like statements
C) A type of flowchart
D) A compiler that translates code
Correct Answer: B
Pseudocode is a simplified, language-independent notation that uses
natural language and structured statements to describe an algorithm. It
is not executed by a computer but is used for planning and
communication.
4.
Which of the following symbols is typically used to represent a decision
in a flowchart?
A) Oval
B) Rectangle
C) Diamond
D) Parallelogram
, Correct Answer: C
In flowcharts, a diamond (or rhombus) represents a decision point
where a condition is evaluated, leading to two or more possible paths.
Ovals are start/end, rectangles are processes, parallelograms are
input/output.
5.
In a flowchart, what does a rectangle represent?
A) Start or end of a process
B) Input or output
C) A processing step or calculation
D) A decision point
Correct Answer: C
A rectangle in a flowchart represents a processing step, such as a
calculation or assignment. Ovals are start/end, parallelograms are
input/output, and diamonds are decisions.
6.
Which of the following is an example of a valid identifier in most
programming languages?
A) 2ndValue
B) total_score
C) my-value
D) class
Correct Answer: B
Identifiers usually must start with a letter or underscore, contain letters,
digits, or underscores, and not be reserved words. "total_score" follows
