requires the output from the preceding step.
(B)A parallel computing solution may not be appropriate for an algorithm in which the same
formula is applied to many numeric data elements.
(C)A parallel computing solution may not be appropriate for an algorithm that can be easily
broken down into small independent tasks.
(D)A parallel computing solution may not be appropriate for an algorithm that searches for
occurrences of a keyword in a large number of documents. - ✔✔(A)A parallel computing
solution may not be appropriate for an algorithm in which each step requires the output from

A certain social media application is popular with people across the United States. The
developers of the application are updating the algorithm used by the application to introduce a
new feature that allows users of the application with similar interests to connect with one
another. Which of the following strategies is LEAST likely to introduce bias into the application?
(A)Enticing users to spend more time using the application by providing the updated algorithm
for users who use the application at least ten hours per week
(B)Inviting a random sample of all users to try out the new algorithm and provide feedback
before it is released to a wider audience
(C) Providing the updated algorithm only to teenage users to generate excitement about the
new feature
(D)Testing the updated algorithm with a small number of users in the city where the developers
are located so that immediate feedback can be gathered - ✔✔(B)Inviting a random sample of
all users to try out the new algorithm and provide feedback before it is released to a wider
audience
,Which of the following best describes a direct benefit in using redundant routing on the
Internet?
(A) Redundancy enables messages to be transmitted with as few packets as possible.
(B) Redundancy enables network devices to communicate with as few network connections as
possible.
(C) Redundancy often allows messages to be sent on the network even if some network devices
or connections have failed.
(D) Redundancy prevents network communications from being intercepted by unauthorized
individuals. - ✔✔(C) Redundancy often allows messages to be sent on the network even if some
network devices or connections have failed.
Which of the following is most likely to be a benefit to users of the application?
(A) The application allows users to identify all other users in a particular area.
(B)Users of the application may be able to easily identify all other users in a particular area as a
result of the application's algorithm for determining whether users are compatible.
(C)Users of the application may see health benefits as a result of the application encouraging
them to exercise with each other.
(D)Users of the application who live in rural areas have the ability to use all the features of the
application, even when they do not have Internet and geolocation connectivity. - ✔✔(C)Users
of the application may see health benefits as a result of the application encouraging them to
exercise with each other.
