Nokia Certification 4A0-255 Exam Is For Nokia Optical Network Design Expert Certification & Nokia Optical Network Architect Certification

4A0-255 Nokia Advanced Optical Network Design certification exam is a popular Nokia certification exam, which towards two certifications as below:

Nokia Optical Network Design Expert Certification

Nokia Optical Network Design Expert Certification is an intermediate level certification in the ONC program that is focused on network design. It targets intermediate to senior level professionals who wish to acquire advanced practical knowledge and experience in the design of Wavelength Division Multiplexing WDM networks based on the Nokia 1830 Photonic Service Switch (PSS), using the 1830 Engineering and Planning Tool (EPT). In addition, it provides a solid background on related topics including optical system engineering, network and site optimization, node architectures, Optical Transport Network (OTN), Generalized Multiprotocol Label Switching (GMPLS), availability and survivability (protection and restoration), as well as advanced requirements such as latency and encryption.

To earn Nokia Optical Network Design Expert Certification, you must pass all mandatory written exams before attempting the Nokia Optical Network Design Expert lab exam.

Nokia Optical Network Architect Certification

Nokia Optical Network Architect certification is designed for intermediate to senior-level professionals and focuses on advanced-level topics in the three core areas:

● Network design

● Network management

● Diagnostics and troubleshooting

Nokia Optical Network Architect Certification requires candidates to pass all four exams and then go on for the lab exam:
