Definitely TRUE. It's a security feature for VLANs.

So, does that mean they can't even ping each other?

Yep, that's how isolation works. No traffic between hosts.

B) FALSE, obviously. Who designs a switch that can't even talk to itself?

B) FALSE, for sure. Port isolation shouldn't affect Layer 3 communication.

I feel like it might be FALSE since VLANs usually allow communication, but port isolation changes that, right?

I practiced a similar question, and I believe it was TRUE. Port isolation really restricts traffic between devices in the same VLAN.

I'm not entirely sure, but I remember something about port isolation limiting Layer 2 communication. Could it be FALSE?

I think it's TRUE because port isolation is meant to prevent communication between hosts in the same VLAN.

Hmm, I'm not sure about this one. I'll need to carefully consider the implications of port isolation at each layer. Better not to guess on this.

I've got this! Port isolation blocks Layer 2 switching between ports, but Layer 3 routing should still work. The answer is FALSE.

Wait, I'm a little confused. Isn't port isolation supposed to prevent communication between ports on the same VLAN? I'll have to review my notes.

Okay, I remember learning about port isolation in class. I think the key is understanding how it impacts Layer 2 and Layer 3 connectivity.

Hmm, this one seems tricky. I'll need to think through the layers of the OSI model to figure out how port isolation affects communication.
