Q4:
According to the SAP-egress policy configured and applied, which queue will EF traffic use?

A
Queue 2 in 'policer-output-queues,' the default queue group used by policers on egress, because there are no queues in the 'qg-10' queue-group template.○
B
The local SAP's queue 1, because there is no queue in the 'qg-10' queue-group template for EF traffic.○
C
Queue 1 in the 'qg-10' queue-group, because it exists by default and all traffic is mapped to it.○
D
EF traffic is dropped because there are no queues in the 'qg-10' queue-group template.
