01. Malicious code appears across an IoT estate. Analysis shows it propagates from device to device across the network on its own, without any user opening a file or running a program.
Which classification best fits, and on what basis?
a) Ransomware, because malicious code on many devices at once implies an extortion motive
b) A virus, because code that spreads between machines is by definition a virus
c) A Trojan horse, because the code arrived on devices that were already in service
d) A worm, because it spreads with no user action and no host file
02. Which connected thing is characteristic of the defense market sector?
a) A self-serve kiosk
b) A continuous positive airway pressure machine
c) A connected warfighter
d) A protection relay
03. After a connected conveyor stopped unexpectedly and a worker was injured, an operator replaced the faulty sensor, returned the line to service, and closed the incident.
Which criticism of that response is best founded?
a) The line should have remained out of service until the product had been certified against a safety standard
b) The failure was addressed without establishing why the sensor failed
c) The response should have transferred the residual risk to the equipment supplier
d) The operator should have graded the hazard before replacing the sensor
04. Which situation is an example of the biological and medical category of IoT safety concern?
a) A connected treatment device delivering an incorrect therapy
b) A robotic cell injuring a worker on a production line
c) A regional loss of electrical supply lasting several days
d) Counterfeit components being fitted during a service visit
05. An offshore survey buoy has to report readings from open ocean, far outside the reach of any terrestrial network, and its position changes with the current.
Which long-range connectivity option is appropriate?
a) Zigbee
b) Satellite
c) Cellular
d) Bluetooth Low Energy
06. A produce packer wants its line to identify bruised fruit from camera images and reject it automatically, without an inspector grading each item.
Which artificial intelligence technique is being applied?
a) Computer vision
b) Prescriptive analytics
c) Streaming analytics
d) Natural language processing
07. During integration and testing of a connected metering system, the team finds that nobody has established how meters will be taken out of service, how the readings already gathered will be dealt with, or how a removed meter's credentials will be withdrawn.
Which phase should have set those expectations, and why does discovering the gap now cause difficulty?
a) Implementation, because credentials are issued as the system is released into production
b) Requirements analysis, because end-of-life handling is a requirement the design must satisfy
c) Operations and maintenance, because the meters are only withdrawn once they have been in service
d) Disposition, because that phase owns device retirement and the disposal of their data
08. An architecture review has to justify why the IoT platform runs its analytics services in containers on hosts that are themselves virtual machines.
Which statement describes what each virtualization technology contributes?
a) Both technologies exist only in the cloud tier and cannot be used on gateway or edge hardware
b) Containers divide one host into machines each with an operating system, while the hypervisor packages an application
c) Both technologies perform the same isolation, so stacking them adds only overhead
d) The hypervisor divides one host into machines each with its own operating system, while containers package an application to share one
09. Two obstacles are reported on the same IoT program. At a rural site, devices cannot hold a link to the platform long enough to report. At an older urban plant, the machinery predates any network interface and cannot be connected without physical modification.
Which pairing correctly names the two challenges?
a) The rural site is a retrofit concern; the urban plant is a coverage concern at the mounting point
b) The rural site is a coverage concern; the urban plant is a retrofit concern
c) Both sites present connectivity and coverage concerns at different scales
d) Both sites present scalability concerns arising from legacy solutions
10. Following a safety event on a connected packaging line, an operator both repairs the machine that failed and changes the inspection interval for every machine of that type across its sites.
How do those two responses map onto the corrective and preventive halves of the approach?
a) Repairing the machine that failed is the preventive half, and changing the interval across the fleet is the corrective half
b) Both responses are preventive, because both reduce the chance of a further event
c) Repairing the machine that failed is corrective; changing the interval fleet-wide is preventive
d) Both responses are corrective, because both follow an event that has already occurred
