If a person’s mobile phone was designed to work with 4G technology, what will happen when a 5G network is rolled out in their area?
Their phone will only work when they are out of range of any 5G networks.
They will still have service through the 4G network for at least several years. —–
They will lose service as the 4G network is deactivated to make room for the 5G network.
Their phone will automatically upgrade itself to work with the new 5G network.
What happens after the initial rollout of a new network generation?
The new network generation will continue to be developed and enhanced over its lifetime.
All devices created to work with the previous network generation must upgrade or lose service.
Development of the network is frozen until the rollout of the next network generation.
The previous network generation will be deactivated after a transition period of a few months.

An air purifier manufacturer is looking for ideas on using edge computing to enhance its products and services. Which approach would make use of edge computing technologies?
a scheduling feature that activates a customer’s air purifier at a defined time each day
a device in the customer’s home that detects air quality levels and sends alerts when needed
an automated program that can interpret customer service requests and assign agents accordingly
a local support staff based in the customer’s geographic location for more rapid responses
A large manufacturing company is looking to optimize worker safety on the shop floor. What is a way the company can utilize edge computing to help achieve this?
Deploy robots that move across the shop floor and clean the work area before new workers can enter the workspace.
Use a central unit to log workers’ current safety equipment and process what equipment is needed before future jobs.
Require supervisors to verify workers are wearing the correct protective gear before they can enter the shop floor.
Provide safety training videos at workstations on the shop floor to ensure proper machine operation by workers.

A frozen-food factory needs to monitor temperatures on machines, check inventory of supplies, and provide sensors on lights and doors. What should the factory do to address these needs?
improve the latency over the wireless network
add antennas inside and outside the building
use more cell sites to better record daily activity
install devices that utilize edge computing
How does beamforming improve network service?
by sharing service signals between devices on a network
by connecting devices directly to power sources
by using multiple antennas to increase range and bandwidth
by using device locations to better target service signals
An electronics company develops a line of augmented reality headsets for use in interactive 3D media applications using 5G mmWave technology. However, customers in rural areas have been complaining about issues with an inability to connect more than their urban and suburban counterparts. What could be contributing to the connectivity issues encountered by the rural customers?
The rural areas do not have enough cell locations to support mmWave.
The signals from the headsets are being downgraded to an earlier generation.
The cell towers in the rural areas are not large enough to support mmWave.
The connection density in the rural areas is too high, causing reduced bandwidth.
What is a distinguishing feature of 5G mmWave?
It can transfer large amounts of data quickly.
It can support an infinite number of devices.
It can easily penetrate walls and barriers.
It has better reception for indoor use.

What does latency indicate?
the amount of lag time between an action and response
the number of MIMO antennas used to connect a device
the number of devices currently connected to the network
the amount of energy needed to establish a network connection
I don’t know this yet.
How does lower latency benefit the users connected to a network?
by enabling more devices to connect to the network at the same time
by reducing the delay when sending and receiving data between devices
by expanding the range over which the network’s signals are transmitted
by limiting network access to users with higher security credentials
