Multiple choice
  1. Web server

  2. Web bionic

  3. Firewall

  4. Chrome 09

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Firewalls monitor and control network traffic between networks based on security rules. They inspect file transfers, block unauthorized data, and prevent malicious traffic. Web servers host websites, and 'web bionic' is meaningless (likely a typo). 'Chrome 09' is not a security utility. Firewalls are the correct answer as they are specifically designed for monitoring and restricting traffic between networks.
