Exam N10-008 topic 1 question 433 discussion

Port security, also known as persistent MAC learning or Sticky MAC, is a security feature that enables an interface to retain dynamically learned MAC addresses when the switch is restarted or if the interface goes down and is brought back online. This is a security feature that can be used to prevent someone from unplugging their office computer and connecting their own laptop to the network jack without permission since the switch port connected to that network jack would only allow the computer with the original MAC address to gain connectivity. Prevents unauthorized access to a switchport by identifying & limiting the MAC addresses of the hosts that are allowed. Port security refers to blocking unauthorized access to the physical switchport that's being used to allow the host to communicate on the LAN & mitigate MAC flooding by allowing only specific MAC addresses to communicate over a given switchport. This makes sure that only packets with a permitted source MAC address can send traffic through the switchport.

To ensure that only a specific workstation can connect to port 1 on a switch, the computer engineer should configure: B. Port security Port security is a feature that allows the restriction of access to a switch port based on the MAC address of the connected device. By configuring port security, the engineer can specify which MAC address is allowed to connect to the designated port, thereby controlling access to that port. Options A (Port tagging), C (Port mirroring), and D (Port aggregation) are different features used for various purposes: - A. Port tagging is related to VLANs (Virtual Local Area Networks). - C. Port mirroring is used for traffic analysis and monitoring by copying traffic from one port to another. - D. Port aggregation involves combining multiple physical ports into a single logical port for increased bandwidth and redundancy.
