Which of the following is an example of a phishing attack?
(A) Loading malicious software onto a user's computer in order to secretly gain access to
sensitive information
(B) Flooding a user's computer with e-mail requests in order to cause the computer to crash
(C) Gaining remote access to a user's computer in order to steal user IDs and passwords
(D) Using fraudulent e-mails in order to trick a user into voluntarily providing sensitive
information - ✔✔D) Phishing is a technique that attempts to trick a user into providing personal
information. In this case, the user is tricked by a fraudulent e-mail
To be eligible for a particular ride at an amusement park, a person must be at least 12 years old
and must be between 50 and 80 inches tall, inclusive. Let age represent a person's age, in years,
and let height represent the person's height, in inches. Which of the following expressions
evaluates to true if and only if the person is eligible for the ride?
(A) (age ≥ 12) AND ((height ≥ 50) AND (height ≤ 80))
(B) (age ≥ 12) AND ((height ≤ 50) AND (height ≥ 80))
(C) (age ≥ 12) AND ((height ≤ 50) OR (height ≥ 80))
(D) (age ≥ 12) OR ((height ≥ 50) AND (height ≤ 80)) - ✔✔A) For a person to be eligible for the
ride, age must be greater than or equal to 12 and height must be greater than or equal to 50
and less than or equal to 80. Therefore, all three of the conditions (age ≥ 12), (height ≥ 50), and
(height ≤ 80) must be true for a person to be eligible for the ride
Which of the following best explains the relationship between the Internet and the World Wide
Web?
(A) Both the Internet and the World Wide Web refer to the same interconnected network of
devices.
(B) The Internet is an interconnected network of data servers, and the World Wide Web is a
network of user devices that communicates with the data servers. (C) The Internet is a local
, network of interconnected devices, and the World Wide Web is a global network that connects
the local networks with each other.
(D) The Internet is a network of interconnected networks, and the World Wide Web is a system
of linked pages, programs, and files that is accessed via the Internet. - ✔✔D) The Internet is the
global system of interconnected computer networks that uses protocols to connect devices
worldwide. The World Wide Web is an information system (of pages, programs, and files) that
is accessible over the Internet.
Which of the following best exemplifies the use of multifactor authentication to protect an
online banking system?
(A) When a user resets a password for an online bank account, the user is required to enter the
new password twice.
(B) When multiple people have a shared online bank account, they are each required to have
their own unique username and password.
(C) After entering a password for an online bank account, a user must also enter a code that is
sent to the user's phone via text message.
(D) An online bank requires users to change their account passwords multiple times per year
without using the same password twice - ✔✔C) Multifactor authentication is a method of
computer access control in which a user is only granted access after successfully presenting
several separate pieces of evidence to an authentication mechanism. In this case, the user
provided a password and showed evidence of having the phone associated with the user
account.
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) If a particular device or connection on the Internet fails, subsequent data
will be sent via a different route, if possible. This is supported by redundancy in the network.
