In Dell SONiC QoS, what is the role of a scheduling algorithm like strict priority or WRR?

To mark packets with a DSCP value

To determine the order in which packets from different queues are transmitted

To classify packets into different traffic classes

To determine which packets are dropped during congestion

A service provider runs Dell SONiC switches. TCP traffic (AF21) and UDP traffic (AF22) share a queue. During congestion, the engineer wants to preferentially drop UDP packets to protect TCP throughput. Which congestion management mechanism should be configured?

WRED with different drop thresholds for AF21 and AF22

Strict priority scheduling for AF21

A retail chain uses Dell SONiC switches. Point-of-sale (POS) traffic is classified by VLAN 100. The network team wants to mark this traffic with 802.1p priority 5 so that downstream switches can prioritize it. The traffic is currently untagged. Which action should be configured?

Set the DSCP value to 46 in the policy map for VLAN 100 traffic

Set the 802.1p priority to 5 in the policy map for VLAN 100 traffic

Configure WRED on VLAN 100 to drop low-priority packets

Apply a shaper to VLAN 100 to limit its rate
