Nokia 4A0-107 Exam Questions

Exam Name: Nokia Quality of Service Exam
Exam Code: 4A0-107
Related Certification(s):
  • Nokia Service Routing Architect Certifications
  • Nokia Triple Play Routing Professional Certifications
Certification Provider: Nokia
Actual Exam Duration: 90 Minutes
Number of 4A0-107 practice questions in our database: 231 (updated: Jun. 02, 2026)
Expected 4A0-107 Exam Topics, as suggested by Nokia :
  • Topic 1: Introduction to QoS: This section of the exam measures the skills of IP Network Engineers and covers foundational knowledge of Quality of Service (QoS). It includes an overview of different types of traffic behaviors and their requirements, outlines the QoS mission statement, and introduces IntServ and DiffServ models. Candidates are expected to understand customer traffic rate limitations and the application of QoS specifically on Nokia 7750 SR platforms.
  • Topic 2: Traffic Classification: This section of the exam assesses the capabilities of Service Delivery Specialists and focuses on classifying incoming traffic based on QoS-related packet header fields. It includes configuration techniques for classifying traffic on SAP-ingress and network-ingress points, as well as the precedence rules for matching criteria. The section also introduces default network policies and outlines how traffic classification is managed at the egress point.
  • Topic 3: Queues and Policers: This part of the exam evaluates the knowledge of IP Network Engineers in handling traffic using queues and policers. It introduces token bucket metering, queue-based traffic shaping, and the concept of Fair Information Rate (FIR). Candidates are expected to understand the process of creating queues and directing traffic to them, differentiating between priority and profile mode queues, and configuring various types of policers. The section also includes buffer management and the use of Weighted Random Early Discard (WRED) techniques, slope policies, and queue groups for traffic redirection.
  • Topic 4: Hierarchical Bandwidth Allocation: This module tests the ability of Service Delivery Specialists to implement bandwidth management using hierarchical approaches. It begins with an overview of Class Fair Hierarchical Policing (CFHP), followed by enabling CFHP for both SAP and queue-group policers. It also covers Hierarchical Scheduling (H-QoS), including its activation for queues, policers, and queue groups on SAP and network interfaces. The section ends with a focus on egress port scheduling strategies for standalone and H-QoS-based queues and policers. Module 5 – Marking and Remarking This section evaluates the proficiency of IP Network Engineers in the marking and remarking of packet headers to support QoS policies. It includes concepts related to modifying encapsulated packet fields and handling customer packet headers in Layer-2, VPRN, and IES services. The goal is to ensure that candidates understand how marking decisions influence traffic handling within QoS-enabled services.

Traffic policing versus shaping questions were calculation-heavy, often giving a traffic profile and asking whether packets get dropped or delayed under a given token bucket. A colleague passed after doing hands-on labs to internalize CIR, PIR and burst math. Practice token bucket calculations and simulate device behavior under bursts.

Traffic classification and marking came up in scenario questions asking which DSCP to assign for voice, video, and best-effort flows and how the PHBs will treat them. I passed the Nokia Quality of Service exam and thanks Pass4Success for a good collection of exam questions that helped me prepare quickly. Study DSCP values, classification rules, and how marking interacts with downstream policies.

Interestingly, on the Nokia 4A0-107 one question framed classification and DSCP re-marking in layers which made the packet flow logic confusing until I traced each hop.
