Exam Number: 4A0-C01
Credit Towards Certifications: Nokia Network Routing Specialist II
Nokia Service Routing Architect
Mandatory Exam Prerequisites: N/A
Exam Duration: 120 minutes
Exam Appointment Duration: 165 minutes. This is the exam duration plus a 45 minute tutorial on computer-based examinations.
Number of Questions: 70
Language: English

The NRS II Composite Exam combines content from the three individual exams required for NRS II certification into a single, integrated exam. The three individual exams are:

  • Nokia Interior Routing Protocols (4A0-101)
  • Nokia Multiprotocol Label Switching (4A0-103)
  • Nokia Services Architecture (4A0-104)

The NRS II Composite Exam will be used for both certification and recertification purposes:

  • For NRS II certification, candidates will have the option to write the single NRS II Composite Exam or write the three individual exams outlined above.
  • For NRS II recertification, the NRS II Composite Exam replaces the previous recertification requirement, which was to write the Nokia Services Architecture exam (4A0-104). Writing the 4A0-104 exam is no longer an option for NRS II recertification. In addition to the composite exam, there are also other NRS II recertification options available to you which can be reviewed at networks.nokia.com/src/recertification.

The NRS II Composite Exam covers topics from all three of the recommended prerequisite courses for NRS II certification:

  • Nokia Interior Routing Protocols
  • Nokia Multiprotocol Label Switching
  • Nokia Services Architecture

The following list provides broad guidelines for the type of content that may be included in the exam. Other material not described here may be incorporated into the exam.

  • 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
