Multiple choice

What is the purpose of the SSL/TLS protocol in mobile device connectivity?

  1. To encrypt data

  2. To establish a connection between two devices

  3. To ensure reliable data transmission

  4. To assign IP addresses to devices
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The SSL/TLS (Secure Sockets Layer/Transport Layer Security) protocol is responsible for encrypting data transmitted between two devices. This ensures that the data is protected from eavesdropping and unauthorized access.

Multiple choice

What is the primary function of a network intrusion detection system (IDS)?

  1. Data Transmission

  2. Data Encryption

  3. Data Routing

  4. Network Security
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

A network IDS's primary function is to monitor network traffic for suspicious activities and potential security threats, alerting network administrators to potential security breaches.

Multiple choice

How can robots be utilized to improve access control and identity verification in secure facilities?

  1. By scanning and verifying biometric data (e.g., fingerprints, facial recognition)

  2. By issuing and managing access cards or credentials

  3. By monitoring and controlling entry and exit points

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Robots can be utilized to improve access control and identity verification in secure facilities by scanning and verifying biometric data (e.g., fingerprints, facial recognition), issuing and managing access cards or credentials, and monitoring and controlling entry and exit points.

Multiple choice
