How does an untrusted interface at the boundary of an administrative domain handle incoming packets?
An untrusted interface at the boundary of an administrative domain handles incoming packets by remarking all values to a CoS of 0. This is done to ensure that any QoS markings from untrusted sources are not accepted and only the trusted devices within the administrative domain can set the QoS policies.
These questions need to be more explanative. I was thinking untrusted in the context of VLANs.
It's A In the context of Quality of Service (QoS) and trust boundaries, an "untrusted" interface typically does not trust the markings (like DSCP or CoS values) on incoming packets.
