Nokia NRS II Composite Exam (4A0-C01) Practice Exam
Nokia NRS II Composite Exam (4A0-C01)
Nokia NRS II Composite Exam (4A0-C01)
The Nokia Network Routing Specialist II (NRS II) certification builds on the foundational knowledge established in the NRS I certification. The goal of NRS II training is to provide students with a strong foundation in the core aspects of Nokia service routing including the Internet Routing Protocol (IRP), IP/MPLS networks, and implementing Nokia layer 2 and layer 3 services.
Prerequisites
To achieve the certification, candidates are not required to enroll in the recommended course to achieve the NRS II certification however passing the mandatory exams and the NRS II practical lab exam are required.
Candidates have the option to write the single NRS II Composite Exam (4A0-C01) or write the following three individual exams.
- Nokia Interior Routing Protocols (4A0-101)
- Nokia Multiprotocol Label Switching (4A0-103)
- Nokia Services Architecture (4A0-104)
The NRS II Composite Exam (4A0-C01) combines content from three individual exams into a single, integrated exam.
Course Structure
The following list provides broad guidelines for the type of content that may be included in the exam.

● Configure RSVP-TE LSPs using each of the possible protection mechanisms
● Understand how to manage, monitor and perform basic troubleshooting of LDP-established LSPs on the Nokia 7750 Service Router (SR) and Nokia 7450 Ethernet Service Switch (ESS)
● Understand how to manage, monitor and perform basic troubleshooting of RSVP-TE-established LSPs on the Nokia 7750 SR and Nokia 7450 ESS
● Demonstrate a basic overall understanding of Nokia services
● Differentiate between the service access point (SAP) and network ports
● Provide an explanation for a service delivery point (SDP) and differentiate between mesh and spoke SDPs
● Differentiate between transport tunnels and service tunnels

● Explain the different types of SAP encapsulations and describe their behavior
● Correctly configure a VPLS service
● Define and configure an Internet enhanced service (IES)
● Configure an IES spoke termination to a VPLS service
● Identify reasons to use mirror services and differentiate between local and distributed mirror services
● Configure and verify the operation of a remote mirror service
● Identify the protocols and technologies required to implement VPRN service
● Explain the interaction between the control and data plane of a VPRN service
● Configure, verify, and troubleshoot an IPv4 and IPv6 VPRN service
