How to Pass the Nokia 4A0-107 Exam: Comprehensive Nokia Quality of Service Guide and Tips

A customer is complaining that his VoIP traffic is being dropped even though it is sending the correct DSCP markings. Packets are not being dropped on ingress.

A customer is complaining that his VoIP traffic is being dropped even though it is sending the correct DSCP markings. Packets are being dropped on ingress.

A commercial builder has requested numerous dot1Q epipes, VPRNs, and VPLS services to a business park and is only paying up to a maximum 200Mbps.

An equipment manufacturer has requested a NULL epipe service that will transparently pass dot1Q between the new location and national headquarters.

If CIR = PIR, then all packets will be considered as in-profile.

CIR can be set to 0.

CIR can be larger than PIR.

CIR can be set to ‘max’.

Limiting the maximum forwarding rate of each individual policer and, at the same time, marking, packets as in-profile or out-of-profile.

Putting packets in a buffer as they are received, and marking packets as in-profile or out-of-profile as they are removed from the buffer.

Rate-limiting the collective output of several policers, and to reallocate bandwidth that is not utilized by some policers to other policers that need to use it.

Rate-limiting the collective output of several policers towards each egress FFPC, while maintaining control of the maximum overall forwarding rate.

During the allocation of within-CIR bandwidth.

During the allocation of above-CIR bandwidth.

During the allocation of both within-CIR and above-CIR bandwidth.

The port scheduler does not use the level of a child for making bandwidth allocation decisions

Packets can be classified into 16 different FCs when using priority mode queuing.

This feature is available on egress SAPs within any service.

MPLS EXP bits can be changed based on multi-field classification.

If a Behavior Aggregate (BA) and Multi-field (MF) match occurs, only the MF override parameters will take effect.

If a Behavior Aggregate (BA) and Multi-field (MF) match occurs, the BA classification can override the forwarding class while the MF classification can override the profile.

It enables CFHP.

It more scalable than using policers.

It allows a separate set of queues/policers for each VLAN on a port.

It allows a set of queues to be shared among multiple SAPs.
