I recently passed the Nokia Optical Networking Fundamentals exam, and I have to say, the Pass4Success practice questions were incredibly helpful. One question that stumped me was about the different types of WDM networks and their applications. I wasn't entirely sure about the specific advantages of CWDM over DWDM, but I managed to get through it.

Free Nokia 4A0-205 Exam Actual Questions

Note: Premium Questions for 4A0-205 were last updated On Apr. 24, 2025 (see below)

Question #2

Which statement is correct about the NFM-T network map?

Reveal Solution Hide Solution
Correct Answer: C

The NFM-T network map provides a graphical view of the network with different colors used to represent each node, physical connection, and active alarm. It allows the user to quickly identify any issues in the network and provides context sensitive navigation.


Question #3

Which of the following statements is true about chromatic dispersion (CD)?

Reveal Solution Hide Solution
Correct Answer: C

Different wavelengths propagate at different speeds within the same media and therefore different colors travel in the fiber with different speed. This phenomenon is known as chromatic dispersion and causes light to spread out as it travels through the fiber over distance, leading to signal attenuation and distortion. The fiber attenuation does not introduce inter-channel interference, but it can cause attenuation of the signal. Different channels have different bandwidths, but this does not affect CD performance.


Question #4

What is the definition of OSNR?

Reveal Solution Hide Solution
Correct Answer: C

The OSNR is defined as the ratio between the average optical signal power and the average optical noise power over a specific spectral bandwidth. This is also known as the signal-to-noise ratio (SNR), and it is a measure of how much signal is present in the optical signal compared to the noise, usually expressed in decibels (dB).
