Infrastructure Latest Exam with Actual
Answers 2025-2026 Updated.
1st wave of IoT - Answer Hardware breakthrough that aimed to connect everyday objects to
a network
2nd wave of IoT - Answer Developing new types of sensors and new technologies and
protocols to support their deployment
3rd wave of IoT - Answer Data collection, processing, and security
IoT ecosystem - Answer Set of stakeholders that participate in the deployment of IoT
technology and the relationship between them
Information provider - Answer Owners of sensor deployments.
Collects and makes data available to others without giving up ownership rights of the
information.
They also build dedicated services or applications.
Platform provider - Answer Provides computing and storage infrastructure, analytics as well
as AI capabilities
Application developers - Answer Produce applications that process the available data within
a specific context to produce actionable insight for end users.
End users - Answer Private persons or institutional decision makers that use information and
applications provided by other stakeholders
Cybersecurity - Answer Practice of protecting information systems, networks, data and
programs
Cyberspace - Answer Network of hundreds of thousands of interconnected computers,
servers, routers, switches and fiber optic cables that allow vital infrastructures to work
,Information systems - Answer Combinations of hardware, software and networks that are
integrated together to collect, process, store and distribute data
Information broker - Answer Module used to store IoT data received from sensors or from
the cloud
Internet - Answer Global network of wired and wireless networks
Web - Answer Information space consisting of a number of public resources that are linked
together and made accessible via the internet
Cyber terrorists - Answer Uses cyberspace to disrupt critical infrastructures to elicit
widespread panic and loss of public confidence in the ability of government to function
effectively, such as by interrupting critical infrastructure
Consumer IoT - Answer All the user's networks around their personal and home devices
Industrial IoT - Answer Machines, computers and people enabling intelligent industrial
operations using advanced data analytics for transformation business outcomes
Internet of Bodies (IoB) - Answer Connected devices that monitor the human body, collect
physiological, biometric, or behavioral data and exchange information of a wireless or hybrid
network. Can be implanted, swallowed or worn.
Wireless Personal Area Network (WPAN) - Answer Short-distance network that allows
multiple devices within a small area to connect to each other.
Examples of a WPAN are Bluetooth and Zigbee.
Sensors - Answer Devices that respond to inputs from the physical environment and use
those inputs for decision-making by displaying the inputs, transmitting them for additional
processing, or using them in conjunction with artificial intelligence
Sensor data - Answer Measurements of some physical property. Data has values, a time and
location. There are fixed and mobile sensors.
, IoT devices - Answer Simple networked devices such as sensors and actuators that are
installed close to the data source or control interfaces. Usually connected via 3G, 4G, 5G, Wi-Fi,
PCIe, USB or Ethernet within an edge computing application scenario.
Edge processing - Answer A process of data aggregation, manipulation, bandwidth
reduction, and other logic directly on an IoT sensor or device
Access network - Answer Part of a network which is concerned with moving data to and
from a sensor or edge device to a backhaul network
Gateway - Answer Building block used to move collected data (from sensors) to the central
IoT platform.
LPWAN (Low Power Wireless Area Network ) - Answer Lower than 1 GHz, 868 MHz in EU
called ISM (Industrial, Scientific, and Medicine) band,
USA 915 MHz
Several techs that use this band are Sigfox, LoRaWAN, and Weightless
LPWANs have lower data rates compared to normal cellular ones
WLAN (Wireless Local Area Network) - Answer Group of collocated computers or other
devices that form a network based on radio transmissions rather than wired connections
What are the 4 things to consider when choosing IoT connectivity? - Answer Data rate,
power availability, range, cost
Customer Edge Device - Answer Devices that receive data from and send commands to IoT
devices.
Mobile Edge Computing (MEC) - Answer Computer node that focuses on data aggregation,
compression and transformation. The ___ server may suffer from resource limitation.
Centralized IoT platform - Answer Powerful central storage and processing capability for IoT
use cases such as data interoperability and uniform data access. Handles management of IoT
devices for remote management.
