Cisco Cyber Security Practice Exam

What technology connects billions of devices, such as appliances and locks, to the Internet?

1. Blockchain

2. Artificial Intelligence

3. IoT

4. Cloud Computing

The correct answer is: IoT

The technology that connects billions of devices, including appliances and locks, to the Internet is the Internet of Things (IoT). IoT refers to a network of physical objects embedded with sensors, software, and other technologies that communicate and exchange data with other devices and systems over the internet. This capability enables seamless interaction and automation, making it possible for everyday devices to send and receive data, providing enhanced convenience, control, and efficiency. By integrating IoT solutions, various environments—home, industrial, and urban—can be monitored and managed in real-time. For example, smart home devices like thermostats can adjust temperatures based on user preferences, and security systems can alert users of any unusual activities. Understanding IoT is crucial in cybersecurity, as the more devices that are connected to the network, the greater the potential attack surface for cyber threats. This makes knowledge of IoT essential for implementing proper security measures and protocols to protect user data and device integrity.
