What does it mean to configure a switch port to 'trust' incoming DSCP markings?

The switch ignores the DSCP value and uses the 802.1p priority instead

The switch uses the DSCP value in the incoming packet to determine the QoS treatment

The switch drops all packets that do not have a DSCP value

The switch overwrites the DSCP value with a default value

What is the primary role of DSCP in an IP packet?

To mark the packet with a QoS class that can be used by network devices to apply appropriate forwarding treatment

To encrypt the packet payload for secure transmission

To identify the application that generated the packet

To indicate the source and destination IP addresses of the packet

When a switch port is configured to 'override' incoming DSCP markings, what happens to the DSCP value?

The switch uses the 802.1p priority to set the DSCP value

The switch preserves the incoming DSCP value

The switch removes the DSCP field from the IP header

The switch replaces the incoming DSCP value with a configured default value

A network engineer is configuring QoS on Dell PowerSwitch campus switches. The organization uses DSCP AF41 (34) for video conferencing traffic. The engineer needs to ensure that when this traffic traverses Layer 2 segments, it receives the highest-priority treatment that the 802.1p standard provides. Which 802.1p priority value should the DSCP AF41 marking map to?
