Nokia Exam 4A0-205 Topic 5 Question 21 Discussion

Actual exam question for Nokia's 4A0-205 exam

Question #: 21
Topic #: 5

WDM allows transmission systems to:

ATransport multiple signals transparently, onto several wavelengths, all together over one single fiber

BIncrease the bit rate of each client signal by spreading it over multiple wavelengths

CShare a single signal among multiple fibers doing load balancing, and thus increasing the reliability of the optical transmission

DAllocate different signals to different time slots

Show Suggested Answer

Suggested Answer: B

A trail is a transparent transport of a client signal. A trail is a physical link between two points in an optical network, allowing for the transport of a client signal from one point to the other. It is a low-order signal, such as a 10G Ethernet or a Fibre Channel signal, encapsulated into a high-order container, such as a 40G or 100G signal. This allows for the transport of the client signal over longer distances, increasing the power budget of the optical link.

I think the answer is A, because WDM allows multiple signals to be transported over one fiber.
