The Nokia Quality of Service Exam course teaches and expands on the theory, tactics, and methodologies to implement quality of service (QoS) approaches in IP/MPLS networks. The course teaches the basic QoS performance measures and describes the fundamental QoS functions required to guarantee that varied traffic flows are treated appropriately. The QoS functions of traffic categorization, marking, buffering, buffer leadership, scheduling, and rate restriction are thoroughly described and reinforced with hands-on laboratories that allow participants to see the impact of each.

After completing this course, students will grasp the ideas and principles of QoS, comprehend the necessity for QoS, and learn how to set up QoS using the Nokia 7750 Service Router (SR) to create differentiated services.

The 4A0-107 Nokia Quality of Service Exam Certifications are connected to Nokia Quality of Service and contribute to the Nokia Services Routing Architect Credential. This 4A0-107 exam confirms the ability to define the business drivers of QoS and describe traffic categorization, queuing, scheduling, and marking concerning QoS. It also addresses the ability to specify the necessity for a multi-tiered scheduling (HQoS) architecture on SAP entrance and expression and how to apply QoS ideas to the relevant service.

  1. Packets for a layer-2 service might be pre-marked at SAP-ingress.
  2. Packets about a layer-2 service can be pre-marked at network entry.
  3. Packets about layer-3 services can be pre-marked at SAP-ingress.
  4. Packets about a layer-3 service may have been pre-marked at network entry.

Question 2:

When selecting how to distribute the bandwidth available among its smaller siblings, when can a port scheduler look at the ”level” of a child?

  1. During the allotment of internal CIR bandwidth
  2. During the distribution of higher-CIR bandwidth
  3. During the distribution of bandwidth within and above the circumference of the CIR.
  4. The connection scheduler doesn’t employ a child’s level to determine bandwidth allocation.

Question 3:

Which of the following phrases reflects a queue’s value parameter for hierarchical scheduling?

  1. The weight sets the queue’s priority during scheduling up to its CIR.
  2. The weight sets the queue’s priority for above-CIR planning up to the PIR.
  3. The weight determines how this queue and other queuing or schedulers at the same CIR level split the available CIR throughput at that level.
  4. The weight determines how this queue, alongside additional queues or planners at the same level, splits the available above-CIR bandwidth at that tier.

Question 4:

Which of the following assertions concerning CFHP’s police hierarchy is false?

  1. A root judge can be the parent of a layer 2 arbiter.
  2. A tier 1 arbitrator can be the parent of a law enforcement officer.
  3. A kind police officer’s priority level might range from zero to ten.
  4. A parent arbiter uses weight to allocate bandwidth between children with equal levels.

Question 5:

An egress port planner connected to an Ethernet connection has a data rate of 100 Mbps. All frames sent via the port are 80 bytes. What is the total transmitting capacity for all queues utilizing the port scheduler?

  1. 100Mbps multiplied by 20/(80 + 20) equals 20 Mbps.
  2. 100Mbps multiplied by 80/(80 + 20) equals 80Mbps.
  3. 100Mbps
  4. 100+ 100 * 20/(80 + 20) = 120 Mbps
