Two switches, S$1$ and S$2,$ are connected to each other. To realize segmentation and greater security, each switch has three VLANs configured $($students$,$ faculty, and IT$).$ When a faculty endpoint connected to S$1$ communicates with a faculty endpoint connected to S$2,$ how does S$2$ know the message belongs to the faculty VLAN?

Group of answer choices

S$1$ tags the message, indicating it belongs to the faculty VLAN when sending it to S$2.$

A logical VPN implemented between the two switches tags the message when sending it$.$

S$1$ uses the vendor$-$neutral IEEE $802\mathrm{.}11$ protocol to tag the message when sending it to S$2.$

A router needs to be used between the switches to ensure successful delivery of VLAN messages.
