ACCOUNTANTS 1 OA ACTUAL EXAM PREP
QUESTION BANK WITH RATIONALES
Master the WGU D522 Objective Assessment with this comprehensive
200-question mock exam complete with detailed answers and expert
rationales. This study bank mirrors actual exam structures, testing
both fundamental Python for IT automation syntax and advanced
accounting data analytics principles. It serves as an essential resource
for students aiming to verify their core technical competencies and
pass their proctored assessment on the first attempt.
Question 1
An accountant has just completed scoping a data request and assessed
potential business risks. What must the accountant do next?
A. Request system administrator credentials.
B. Determine what specific data is needed and in what format.
C. Clean all null values from the system logs.
D. Build a predictive machine learning model.
Answer: B
Rationale: Immediately after scoping a data request and assessing
potential risks, the next structured analytical step is to determine the
exact datasets needed and their matching structural formats.
,Question 2
An organization relies on a third-party market trend data provider to
target credit customers. Shortly after, the company suffers a severe
spike in defaults due to outdated data points. What ethical data practice
did the organization fail to follow?
A. Ensuring the data was perfectly encrypted.
B. Ensuring that the underlying third-party data was reliable and
accurate.
C. Minimizing data storage footprints.
D. Using an open-source data manipulation library.
Answer: B
Rationale: Data governance and professional ethics demand that any
data utilized for corporate decisions must be regularly verified for
accuracy, reliability, and current relevance before execution.
Question 3
An auditor wants to group customers into segments based on identical
or very close matches across multiple known demographic and
purchasing variables. Which data approach should the auditor use?
A. Link prediction
B. Co-occurrence grouping
C. Similarity matching
D. Profile analysis
Answer: C
,Rationale: Similarity matching is an analytical data method specifically
designed to identify identical or closely aligned individuals or groups
based on shared descriptive categories.
Question 4
An analyst wants to predict whether a vendor and a supplier will
establish an undocumented transaction partnership in the next quarter
based on mutual touchpoints. Which data approach is most
appropriate?
A. Regression
B. Classification
C. Similarity matching
D. Link prediction
Answer: D
Rationale: Link prediction is a network analysis data technique used to
predict hidden or future relationships or links between two separate
data nodes or items.
Question 5
Which type of data object is completely valid for use as a key inside a
Python dictionary collection?
A. List
B. Dictionary
C. Tuple
D. Set
, Answer: C
Rationale: Python dictionary keys must be strictly immutable. Tuples are
immutable and therefore valid, whereas lists, sets, and dictionaries are
mutable and invalid as keys.
Question 6
An engineer wants to use a naming style for variables where the first
word is completely lowercase, and every following word begins with a
capital letter. Which convention represents this style?
A. PascalCase
B. snake_case
C. camelCase
D. Kebab-Case
Answer: C
Rationale: The camelCase convention dictates that the first word starts
lowercase, and each subsequent combined word is capitalized without
spaces or underscores.
Question 7
Which variable naming scheme is characterized by lowercase letters
separated strictly by underscores?
A. PascalCase
B. snake_case
C. camelCase
D. Upper-Case
