Which device permits or denies network traffic based on a set of rules (CCNA 200-301)
Which device permits or denies network traffic based on a set of rules?
A. switch
B. firewall
C. wireless controller
D. access point
Solution
Correct answer: B. firewall.
A firewall is a security device that monitors and filters incoming and outgoing network traffic based on a set of security rules and policies. It is designed to prevent unauthorized access to or from a private network, and it can be configured to block or allow traffic based on various criteria, such as the source or destination IP address, the type of traffic, or the port number.
Switches, wireless controllers, and access points are network devices that are used to forward or manage network traffic, but they do not have the capability to permit or deny traffic based on a set of rules like a firewall does.
