TRUE

FALSE

It may exceed PIR of the queue.

It may be exceeded by the average servicing rate of the queue.

It varies depending on the traffic characteristics.

It is the rate at which packets are forwarded out of the queue.

The root arbiter can be the parent of a tier 2 arbiter.

A tier 1 arbiter can be the parent of a policer.

A child policer can have a priority level from 0 to 10.

Weight is used by a parent arbiter to allocate bandwidth among children of equal level

H-QoS capabilities must be enabled globally on the router

A scheduler-policy must be configured.

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

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

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

The scheduler-policy must be applied on the service SAP.

Set the CBS to 0.

Set the MBS equal to the CBS.

Set the high-priority-only equal to the MBS.

Set the MBS to 0.

Set the high-priority-only to 0.

512 MB ingress, 512 MB egress

256 MB ingress, 256 MB egress

1 GB dynamically allocated between ingress and egress.

768 MB dynamically allocated between ingress and egress.

768 MB, with a minimum of 256 MB ingress and egress, and an additional 256 MB dynamically allocated.

It sets both the forwarding class and the packet’s dot1p, lsp-exp, precedence, or dscp field to the same value.

It groups all packets together into a single aggregate stream, and gives all packets the same treatment.

It copies the three most significant bits in the packet’s dscp field into the forwarding class.

It assigns a forwarding class based on the packet’s dot1p, lsp-exp, precedence, or dscp value.

Scheduler policies cannot be children of an egress port-scheduler.

HQoS provides a static method of allocating scheduling resources to each queue and/or child.

Scheduler policies can be applied to the MDA to schedule network ingress traffic.

Every time a scheduler-policy is assigned to a SAP, a new hardware scheduler is created to service the SAP.

A scheduler applied to multiple SAPs within the same service will result in a single hardware scheduler operating across all SAPs within the service.
