Options :

A : H-QoS capabilities must be enabled globally on the router

B : A scheduler-policy must be configured.

C : The queues in the SAP-ingress and SAP-egress policies do not require additional configuration attributes to make use of the hierarchical schedulers.

D : The network queue policy must be configured to make use of the scheduler-policy.

E : The scheduler-policy must be referenced in the SAP-ingress and SAP-egress policies.

Options :

A : The loopback control PDU instructs the remote port to enter loopback mode.

B : Putting a port in loopback does not affect customer data flow

C : Both ports must rediscover the OAM capabilities of each other once the port is put back into service.

D : Both ports must still send Information PDUs to avoid going back to discovery mode.

E : When a port is in loopback mode, service mirroring will still work if it is a mirror-source or mirror-destination.
