APCSP 2021 Practice Exam MCQ ACTUAL UPDATED QUESTIONS AND CORRECT
ANSWERS
Which of the following is an example of an attack using a A
rogue access point?
A) An unauthorized individual gains the ability to view
network traffic by connecting to a network router that
uses weak or no security measures.
B) An unauthorized individual physically disconnects an
exposed network router, making the network unavailable
to some users.
C) An unauthorized individual poses as a network
administrator and attempts to trick a user into providing
personal information.
D) A group of unauthorized individuals overwhelms a
network router with traffic, making it unavailable to some
users.
Which of the following best explains the ability to solve D
problems algorithmically?
A) Any problem can be solved algorithmically, though
some algorithmic solutions may require humans to
validate the results.
B) Any problem can be solved algorithmically, though
some algorithmic solutions must be executed on multiple
devices in parallel.
C) Any problem can be solved algorithmically, though
some algorithmic solutions require a very large amount
of data storage to execute.
D) There exist some problems that cannot be solved
algorithmically using any computer.
Which of the following best explains how symmetric A
encryption algorithms are typically used?
A) Symmetric encryption uses a single key that should be
kept secret. The same key is used for both encryption and
decryption of data.
B) Symmetric encryption uses a single key that should be
made public. The same key is used for both encryption
and decryption of data.
C) Symmetric encryption uses two keys that should both
be kept secret. One key is used for encryption, and the
other is used for decryption.
D) Symmetric encryption uses two keys. The key used for
encryption should be made public, but the key used for
decryption should be kept secret.
, Which of the following research proposals is most likely A
to be successful as a citizen science project?
A) Collecting pictures of birds from around the world that
can then be analyzed to determine how location affects
bird size
B) Monitoring a group of cells in a laboratory to
determine how growth rate is affected by exposure to
varying temperatures
C) Using a simulation to determine which one from a set
of chemicals causes the most significant change to local
animal and plant life
D) Using specialized equipment to perform three-
dimensional scans of complex proteins found in human
cells
A sorted list of numbers contains 128 elements. Which of B
the following is closest to the maximum number of list
elements that can be examined when performing a
binary search for a value in the list?
A) 2
B) 8
C) 64
D) 128
