MBA 6207 FINAL EXAM WITH CORRECTDETAILED ANSWERS 2024.
Can hackers who gain access to an organization's IoT cause physical damage?
a. no, because physical devices are controlled manually
b. no, because IoT devices only send, not receive, data
c. yes, by infiltrating the public cloud
d. yes, by tampering with critical infrastructure - ANSWER- d. yes, by tampering with
critical infrastructure
Hackers who gain access to an organization's IoT can steal data, transfer money out of
accounts, and shut down Web sites. They can also wreck physical havoc by tampering
with critical infrastructure such as air traffic control systems, health care devices, power
grids, and supervisory control and data acquisition (SCADA) systems.
A single-tenant cloud computing environment is also known as a(n) _____.
a. public cloud
b. private cloud
c. autonomic cloud
d. hybrid cloud - ANSWER- b. private cloud
An enabling technology for cloud computing is autonomic computing, or the ability of IT
systems to manage themselves and adapt to changes in the computing environment,
business policies, and operating objectives.
A positive development for public, private, and hybrid cloud computing environments is
the emerging ability of IT systems to manage themselves and adapt to changes in the
computing environment, business policies, and operating objectives. This ability is
known as _____.
a. cloud virtualization
b. multicloud computing
c. 5G networking
d. autonomic computing - ANSWER- autonomic computing
An enabling technology for cloud computing is autonomic computing, or the ability of IT
systems to manage themselves and adapt to changes in the computing environment,
business policies, and operating objectives.
A common reason an organization chooses a private rather than a public cloud
environment is _____.
,a. budgeting concerns
b. IT staff reductions
c. lack of adequate hardware
d. concerns about data security - ANSWER- d. concerns about data security
Organizations that implement a private cloud often do so because they are concerned
that their data will not be secure in a public cloud.
An organization using a public cloud allows the service provider to store their data in a
remote location, possibly on the same storage device as other organizations' data. This
results in which key concern with the public cloud?
a. vendor lock-in
b. complex pricing arrangements
c. frequent software updates
d. inadequate data security - ANSWER- d. inadequate data security
Data security is another key concern when using a public cloud computing service
because you are relying on someone else to safeguard your data, which may even
reside on the same storage device as data from another organization (perhaps even a
competitor).
As a result of the analysis of aggregated sensor data, an IoT device may receive _____.
a. self-configuring and self-healing instructions
b. a series of new IP addresses
c. a download of data from other systems
d. updates, alerts, or even automatic adjustments - ANSWER- d. updates, alerts, or
even automatic adjustments
To be truly part of the IoT, networked devices need IP addresses and a connection to
the public Internet, which allows the data to be transmitted to an operational historical
database containing data from many sensors. The operational data can be accessed
via the Internet and analyzed by users with personal computers or mobile devices.
Updates, alerts, or even automatic adjustments may be sent to the devices on the IoT
based on this analysis.
Autonomous vehicles will rely on 5G for their _____.
a. sensors
b. human interaction
c. brake function
d. gas mileage - ANSWER- sensors
,Self-driving cars will rely on 5G for their sensors, which interact with other cars on the
road and process traffic and mapping information in real time.
Clara has a device that responds to her voice commands by reviewing her calendar
appointments, performing search queries, and playing streaming music. This is an
example of a(n) _____.
a. fitness tracker
b. smart speaker
c. Tesla device
d. infrastructure enhancement - ANSWER- smart speaker
Smart speakers, such as Google Home and Amazon Alexa, connect to the Internet and
respond to your voice commands to perform functions such as reviewing calendar
appointments, performing search queries, streaming music, and turning on or off lights
connected to smart outlets.
Claudette is shocked to discover that her company's data has been stolen, and their
Web site shut down, by a malicious ex-employee. She had thought their security was
airtight! Two recent changes they made were migrating their database to a private, on-
premises cloud and installing IoT devices that communicate with the database
continually. What most likely occurred?
a. The ex-employee hacked Claudette's company's IoT to gain access.
b. The ex-employee hacked into their private cloud through another tenant's account.
c. The ex-employee broke into their office without leaving a physical trace.
d. The ex-employee gained access through their IaaS provider. - ANSWER- a. The ex-
employee hacked Claudette's company's IoT to gain access.
There is a key decision that organizations must make when considering implementation
of an IoT: Are the benefits of doing so sufficient to overcome the risk of making detailed
company information accessible through the Internet and exposing internal systems to
hacking, viruses, and destructive malware? Hackers who gain access to an
organization's IoT can steal data, transfer money out of accounts, and shut down Web
sites.
Eleanor realizes that the data coming from two of her firm's IoT devices is incomplete
and includes inconsistent values. What is the most likely cause of this problem?
a. faulty sensors
b. long-term network outage
c. vendor lock-in
d. DoS attack - ANSWER- a. faulty sensors
Sometimes a faulty sensor or bad network connection results in missing data or sensor
data that lacks a time stamp indicating when the reading occurred. As a result, sensor
, data can be incomplete or contain inconsistent values, indicating a potential sensor
failure or a drop in a network.
Don's company has contracted with a service provider to receive a computing platform
