Palo Alto Networks (PANW) Certified Cybersecurity Entry-level Technician (PCCET) Practice Exam

Which category of IoT enables real-time use cases, such as autonomous vehicles, with 4G LTE Advanced Pro delivering speeds in excess of 3Gbps and less than 2 milliseconds of latency?

1. Low-power WAN

2. Satellite

3. Cellular

4. Short-range wireless

The correct answer is: Cellular

Cellular technology is indeed the correct choice for enabling real-time use cases like autonomous vehicles, particularly with advancements in 4G LTE Advanced Pro. This category of IoT supports high-speed data transmission exceeding 3Gbps and maintains extremely low latency under 2 milliseconds. Such performance is crucial for real-time decision-making and data exchange needed in applications like autonomous driving, where responsiveness can significantly impact safety and efficiency. The reliability and coverage provided by cellular networks further enhance their suitability for critical IoT applications, allowing devices to communicate over vast distances without being constrained by range limitations typically associated with other wireless technologies. This makes cellular a strong backbone for connecting a myriad of devices in various environments, especially those requiring constant connectivity and rapid data transfer. Other categories such as low-power WAN, satellite, and short-range wireless each have their own use cases and limitations that might not align with the demanding requirements of real-time applications like autonomous vehicles. For instance, low-power WAN is optimized for devices needing long-range communication with minimal power, while satellite delivers global coverage but typically involves higher latency. Short-range wireless technologies, like Bluetooth or Zigbee, enjoy low power consumption but are not suitable for the extensive ranges or high speeds required for these innovative applications. Thus, the performance capabilities
