Nokia Nokia Quality of Service 4A0-107 Exam Dumps: Updated Questions & Answers (October 2025)

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.

The default forwarding class defined in the SAP-egress policy.

The forwarding class inherited from network ingress classification.

Best Effort.

If there is no match, packets will be dropped.

The IOM3 adds more memory to both forwarding complexes which increases the total number of queues available.

The IOM3 only contains a single forwarding complex which reduces the number of queues used.

The IOM3 allows multiple forwarding classes to be assigned to a single queue.

The IOM3 allows queues to be dynamically allocated between ingress and egress.

The IOM3 has a larger CPU capable of tracking active hardware queue utilization and adjusting memory allocation accordingly.

Queue 5 is using priority mode.

UDP traffic can be serviced at a maximum rate of 20 Mbps.

Ping traffic is place in queue 5.

Queues 5 and 6 will receive equal portions of any remaining available bandwidth to meet their above-CIR bandwidth requirements.

Queue 3 is scheduled before queue 5.

The three most significant (first) bits define 8 forwarding classes.

The three least significant (last) bits of the DSCP specify the drop probability.

The full 8 bits of the TOS field are used for DSCP.

To convert DSCP to IP precedence, the three most significant (first) bits are matched.

DSCP provides for eight drop probabilities.

A network policy for every network interface configured on the port.

A slope policy for the port on ingress.

A network queue policy for the corresponding MDA on ingress.

A network queue policy for the port on egress.

HQoS schedulers cannot be children of an egress port-scheduler.

HQoS schedulers provide a dynamic method of allocating scheduling resources to queues.

HQoS scheduler policies can be applied to an MDA to schedule network ingress traffic.

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