Exam SY0-701 topic 1 question 164 discussion

Port security is a feature available on network switches that helps secure access to the physical network by restricting which devices can connect to each network port based on their MAC address. Port Security: This is a network security feature that restricts input to an interface by limiting and identifying MAC addresses of the devices allowed to access the port. It can be configured to block devices that do not match the allowed list. -Control Over Physical Access: By enabling port security on the network jacks, the organization can ensure that only authorized devices with specific MAC addresses are allowed to connect. Any unauthorized devices, such as a visitor's laptop, would be blocked from accessing the network. -Dynamic or Static Configuration: Port security can dynamically learn and store allowed MAC addresses or use a predefined list, providing flexibility in securing physical network ports. This why it is the best answer: Port security directly addresses the issue of unauthorized access through physical network connections by controlling which devices can use the network ports. It prevents unauthorized devices from gaining network access, making it the most appropriate solution for this scenario.

I go more for TLS which is part of EAP-TLS used with 802.1X on the NAC to authenticate. On the other hand, Port Sec. you'll need to either identify the MAC address or Sticky MAC address, so it makes sense to go with C. ### Maybe I'm over-thinking ### :D
