Port isolation can be deployed on an Ethernet network to implement both Layer 2 communication...

Comprehensive and Detailed Explanation:

Port isolationis a feature used to enhance security andnetwork segmentationby restricting communication between certain switch ports atLayer 2while allowing them to communicate throughLayer 3.

Layer 2 Communication:Devices within the same VLAN can communicate with an upstream gateway or router.

Layer 3 Isolation:Devices cannot communicatedirectlyat Layer 2 but must pass through a Layer 3 device (e.g., a router or firewall).

Use Case:Typically used in enterprise networks, hotel networks, and campus networks to preventunwanted direct communicationbetween clients.

Thus, the statement iscorrect, and the answer isTRUE.
