COMPLETE TEST BANK (400 QUESTIONS) Objective

2026/2027 Edition
SECTION 1: PRE-ASSESSMENT (PA) PRACTICE QUESTIONS
Question 1
Management has requested that the development team have a moderator review
their newest module of code. Which type of review is being asked for?
A) Walkthrough
B) Informal
C) Inspection
D) End User
Answer: C) Inspection
Rationale: Inspections are formal reviews that always use a moderator.
Walkthroughs do not typically have a moderator. End-user tests and informal
reviews lack a formal moderator role. Code inspections use a moderator and
follow a structured process for error detection .
Question 2
An informal review of a module of code has been completed. The development
team has decided to evaluate the module from an end user perspective. Which
method should be used to determine if the code meets quality standards?
A) Human
B) Black Box
,C) Inspection
D) White Box
Answer: B) Black Box
Rationale: Black box testing evaluates functionality from an end-user perspective
without examining internal code structure. White box testing examines code logic,
and inspections analyze internal code. Black box testing is the only method that
aligns with an end-user perspective .
Question 3
There is a requirement to verify the usability of a product as it is being delivered
to ensure overall design and functionality without regard to the internal
functioning of the code. Which quality method meets this requirement?
A) Code inspection
B) Black box testing
C) White box testing
D) Peer reviews
Answer: B) Black box testing
Rationale: Black box testing verifies functionality and usability without examining
internal code structure. Code inspections, white box testing, and peer reviews all
examine internal code functioning, making them inappropriate for a purely end-
user perspective .
Question 4
QA proposes a formal group meeting where the programmer narrates, statement
by statement, the logic of a program as an error detection technique. Which
quality method meets this proposal?
A) Peer review
B) Black box testing
,C) Code inspection
D) Grey box testing
Answer: C) Code inspection
Rationale: Code inspections are formal meetings where the programmer explains
the logic of the program statement by statement to detect errors. Peer reviews are
informal, black box testing does not examine code, and grey box testing is not a
formal code narration method .
Question 5
A program's state changes from what is expected. Which practice should be
applied to find the location of the defect?
A) Backtracking
B) Induction
C) Deduction
D) Error Analysis
Answer: A) Backtracking
Rationale: Backtracking works backwards from where the bug was first noticed to
where the cause was introduced. Inductive debugging moves from details to a
general hypothesis, and deduction uses elimination. Backtracking is the specific
technique for locating the exact defect location .
Question 6
A web developer or QA tester encounters an error. What is the best practice to
initiate resolution of this error?
A) Brute force debugging
B) Deduction
C) Reproducing the error
D) Induction
, Answer: C) Reproducing the error
Rationale: Before debugging can begin, the error must be reproducible. Without
reproducible steps, debugging is essentially guesswork. Reproducing the error is
the foundational first step in the debugging process .
Question 7
Which action should a developer take after receiving an email from a QA tester
stating that the application under test is not working?
A) Start to work on each issue in order to fix the application
B) Begin a debugging process to isolate each issue
C) Ask to document each issue with details in a bug report
D) Pass the email on to the lead developer
Answer: C) Ask to document each issue with details in a bug report
Rationale: A proper bug report should include reproduction steps, expected results,
actual results, and environmental details. The developer should request complete
documentation rather than attempting to fix incomplete bug reports .
Question 8
An incomplete bug was identified and reported by the QA team. The bug only
contained a description, an expected result, and an actual result. Which step
should be taken by the developer?
A) Retest the code to see if the error can be reproduced
B) Ask the QA team to provide the steps to reproduce the error
C) Immediately start modifying the code as the developer knows why the error
occurs
D) Tell the QA team that the code was tested and that errors do not exist
Answer: B) Ask the QA team to provide the steps to reproduce the error
