Question 1 of 30

Question 2 of 30
What are some shortcomings of code coverage as a measurement for how well a system or product is
tested? (choose 3 answers)
Correct answer: A) B) C)
You chose: C) D) B)
Note: This question displayed answer options in random order when taking this Test.
Code coverage does not ensure that the most important or highest risk areas of the code are
being exercised by tests.
Code coverage does not necessarily provide functional coverage.
Could create incentives to write tests that simply increase code coverage, rather than tests
that find bugs without increasing coverage.
Code coverage metrics vary by development platform (e.g., .NET, Java)
It is too complicated to explain to management.
You did not select all available correct options.
Points: 0 out of 1
Feedback
Code coverage is a useful metric, but not in isolation. It should not be considered a replacement for effective
test design techniques.
Question 3 of 30
What are two (2) ways a Development Team can ensure a good application architecture?
Correct answer: C) E)
You chose: C) E)
The Development Team plans a Sprint 0 at the beginning of a project with the objective of
developing an architecture model used during the following Sprints.
A Development Team doesn't need an architecture model in Scrum and should focus on
adding functionality. The architecture will come into place without fail as the Development
Team adds functionality.
The Development Team should have a set of guiding architecture principles that every
Development Team member understands and follows when writing code.
The Development Team should assign someone to the role of software architect whose job it
is to make sure a consistent architecture is developed.
The Development Team plans some time each Sprint to discuss the architecture needed for
the features planned in that Sprint.

There is no specific "architect" role on a Scrum team, nor is there an architecture planning Sprint.  But, a good
architecture doesn't just happen automatically.  Guiding principles and frequent conversations on the team help
ensure that the most appropriate architecture is developed as it is needed by features being developed in the
current Sprint.

Question 7 of 30
While changing software, you find a bug in a previously delivered piece of functionality. What should
you do?
Correct answer: A)
You chose: A)
Fix the bug if it is critical or easily fixed. Otherwise, put the new bug into the Product Backlog
to be prioritized and fixed in an upcoming Sprint.
Stub out the code that caused the bug so it no longer occurs.
Revise the tests so that the bug no longer appears on the bug report.
Fix the bug.
Points: 1 out of 1
Feedback
Unless your company has specific guidance on fixing bugs, they represent work to be done and should be
ordered on the Product Backlog by the PO.
Two exceptions are if the work to fix the bug is less than the work to actually log it, or if the bug is so critical
that it would be negligent to leave it unfixed.
