4A0-107 Exam Dumps - Nokia Quality of Service

Several Tier 1, Tier 2, and Tier 3 schedulers can be defined within a policy.

A queue’s parent scheduler must be a Tier-3 scheduler.

The parent must have a higher level in the hierarchy.

If no parent is configured, the queue/scheduler is considered orphaned.

When applied at the FP (Forwarding Path) level for access egress

When applied at an access port for ingress or egress

When applied at the FP (Forwarding Pass) level for access ingress

When applied at the port level for network egress

Has the ability to distinguish traffic in 32 different ways.

Uses the RSVP protocol to create microflows through a network.

Has the ability to manually configure foiwarding classes through a network.

Uses the RSVP protocol to create macroflows through a network.

The EXP field in the bottom MPLS header will be marked.

The EXP field in both the top and bottom MPLS headers will be marked.

For Layer 2 services, the top MPLS header will be marked; for Layer 3 services, the bottom MPLS header will be marked.

The EXP field in the top MPLS header will be marked.

Neither the top nor the bottom EXP field will be marked since EXP remarking can only be done on the network ingress.

Profile-mode and priority-mode queues can only be configured on SAP ingress.

For network egress, egress re-classification can change the profile marked at ingress.

For SAP egress, the profile marked at ingress may change based on the scheduling loop.

For network ingress, the network policy can classify the packet as either in-profile, or out-of-profile.
