Questions and Answers

What is one of the main purposes of implementing port security in a network?

  • To protect the network from unauthorized access and malicious attacks (correct)
  • To provide unlimited bandwidth to all devices
  • To increase network congestion
  • To allow all types of traffic to freely access the network

How does port security help maintain the privacy of a network?

  • By allowing unrestricted access to all devices
  • By not monitoring any devices accessing the network
  • By increasing network congestion intentionally
  • By reducing the risk of security breaches (correct)

What role does port security play in reducing network congestion?

  • By allowing all devices to flood the network with traffic
  • By limiting access to only legitimate devices and traffic (correct)
  • By not implementing any access control measures
  • By ignoring any performance issues on the network
