IT FOUNDATIONS D316 QUESTIONS WITH ACCURATE
ANSWERS
A cloud administrator configures a cloud instance to increase its resources during
times of high utilization and decrease its resources when peak utilization times
end. What cloud characteristic does this represent? correct answer The correct
answer is rapid elasticity
Rapid elasticity refers to the system's ability to handle changes to demand in real
time. A system with high elasticity will not experience loss of service or
performance if demand suddenly increases.
A cloud service provider is taking advantage of software-defined networking
(SDN) to allow customers to provision and deprovision cloud resources on-
demand. Which layer of SDN does the SDN controller operate on? correct answer
The correct answer is Control
In software defined networking, the SDN controller operates on the control layer
between the application layer and infrastructure layer.
A cloud service provides a billing dashboard that reports the uptime, disk usage,
and network bandwidth consumption of a virtual machine. What type of cloud
characteristic does this demonstrate? correct answer Metered Utilization.
A college campus is spread throughout an entire city. There is a plan to upgrade
the connectivity to all buildings for increased speed. What type do engineers
upgrade to? correct answer The correct answer is MAN
,A metropolitan area network (MAN) refers to a specific network type covering an
area equivalent to a city or other municipality. The campus network is this type of
network.
A college that has several campuses in different parts of the city has hired a
network technician. What type of network will the technician most likely be
working on? correct answer The correct answer is MAN
The network technician will be working on a metropolitan area network (MAN),
which can be a company with multiple connected networks within the same
metropolitan area.
A college would like to implement a secured print solution so that print jobs do
not arrive at a printer until the printer is physically interacted with. This will help
prevent students from potentially picking up faculty print jobs. Which two
physical security solutions does the IT department consider to accomplish this?
(Select all that apply.) correct answer The correct answers are PIN Code and
Badging
A secured print job is held on the print device until the user authenticates directly
with the print device. A PIN entry requires the user to input the correct password
via the device control panel.
Secured print mitigates the risk of confidential information being intercepted
from the output tray. Badging means the print device is fitted with a smart card
reader that enables print output to be retrieved.
,A company considers moving its infrastructure to the cloud. Management
emphasizes the need to handle changes in resource usage in real-time. Which
feature fulfills this need? correct answer The correct answer is Rapid elasticity
Rapid elasticity refers to the system's ability to handle changes to demand in real-
time. A system will not experience loss of service or performance if demand
suddenly doubles.
A company has contracted the use of a remote datacenter to offer exclusive
access to platform as a service resources to its internal business users. How would
such a cloud solution be classed? correct answer As a private deployment model.
A company has discovered that an employee has been emailing product design
documents to her smartphone and then saving the files to the smartphone's flash
drive. Which technology can be deployed to prevent such policy breaches?
correct answer Mobile application management (MAM) allows an enterprise to
create a protected contrainer as a workspace for corporate apps and data and
prevent copying to other storage areas.
A company hired a network technician to manage the part of their network that is
based on 802.11 standard. What type of network will the technician be
managing? correct answer The correct answer is Wi-Fi.
The technician will be managing the Wi-Fi portion of the company's network.
Most Wi-Fi networks are based on the IEEE 802.11 series of standards.
A company hired an administrator to manage their computers that host the
employees' shared resources and applications. What kind of computers will the
administrator manage? correct answer The correct answer is server.
, The administrator will manage the company' server computers. A company
dedicates a server computer to running network applications and hosting shared
resources.
A company hires a network technician who is reviewing the network setup
documentation. The technician sees that the company has fiber optic cable
running all the way ip to the building. This represents what type of connection?
correct answer The correct answer is FTTP
A fiber to the premises (FTTP) internet connection means that the service
provider's fiber optic cables runs all the way to the customer's building.
A company implements a new wireless Infrastructure. During the installation, an
engineer adjusts the signal of all antennas for optimal performance. Which setting
does the engineer use to measure dBi? correct answer The correct answer is
Antenna gain.
Antenna gain is the amount that a signal is boosted by directionality. This focuses
the signal in a single direction rather than spreading it over a wide area. Gain is
measured in dBi (decibels isotropic).
A company is ordering custom-built laptops to supply its field sales staff for use
predominantly as presentation devices. The company can specify the type of
panel used and has ruled out IPS and OLED on cost grounds. Which of the
remaining mainstream display technologies is best suited to the requirement?
correct answer Vertical Alignment (VA) displays support good viewing angles and
high-contrast ratios, which makes them well-suited to displaying slides to an
audience. The twisted nametic (TN) type is cheap but does not support wide-
angle viewing.
