NEW QUESTION # 19
Where can the user set the long-haul WT decoder parameter, when designing a network with EPT?
Answer: D
Explanation:
The long-haul WT decoder parameter can be set in the NE parameters when designing a network with EPT. This parameter is used to adjust the sensitivity of the decoder and can help to improve the accuracy of the measurements for long-haul WTs.
The Network Element (NE) parameters in EPT (Element Planning Tool) are used to configure various settings and options for the network elements in the network. The long-haul WT decoder parameter is one such setting that can be configured in the NE parameters section. The user can access the NE parameters by navigating to the NE Parameters menu within the EPT interface. The user can then select the appropriate network element and modify the settings as needed. This information can be found in the Nokia guide for EPT.
NEW QUESTION # 20
Which sentence about NFM-T is correct?
Answer: D
Explanation:
NFM-T is a network management system designed to manage optical networks in a unified manner. It is used to design, manage, and provision optical services having IP nodes as extremities. It supports a variety of technologies, including optical and IP, and fully supports LO, LI, L2, and GMPLS applications. It is mainly focused on the Nokia 1830 PSS product family, as well as other older product families.
NEW QUESTION # 21
Which of the following statements about Wavelength Tracker monitoring points in CDC-F architecture is TRUE?
Answer: C
Explanation:
Comprehensive and Detailed Explanation From Nokia Optical Networking Fundamentals:
In a CDC-F (Colorless, Directionless, Contentionless, Flex-grid) architecture, the placement of monitoring points is vital for end-to-end visibility of wavelengths. Nokia's Wavelength Tracker technology relies on these points to detect the unique "keys" or signatures associated with each wavelength. In a CDC-F node, the primary monitoring points are located on the IRDMxx (Intelligent Reconfigurable Demultiplexer/Mux) line interfaces and the CWR (Colorless Wavelength Router) CLS (Colorless) interfaces.
The IRDM monitoring points allow the system to verify the power and presence of wavelengths as they enter or leave the fiber spans (degrees). The CWR CLS monitoring points are critical because they provide visibility at the "Colorless" add/drop stage. By having monitoring at both locations, the WaveSuite Network Operations Center (WS-NOC) can pinpoint exactly where a signal loss or power degradation is occurring-whether it's in the external fiber plant or within the internal colorless switching fabric of the ROADM. This granular visibility is what allows Nokia's "Power Management" to automate balancing across complex mesh topologies.
NEW QUESTION # 22
Which of the following statements about the contentionless feature on a CDC-F node is TRUE?
Answer: B
Explanation:
Comprehensive and Detailed Explanation From Nokia Optical Networking Fundamentals:
The term CDC-F stands for Colorless, Directionless, Contentionless, and Flex-grid. While "Colorless" allows any wavelength on any port and "Directionless" allows any port to be routed to any output fiber (degree), Contentionless solves a specific physical limitation of traditional multiplexers. In a standard ROADM, you cannot drop the same wavelength (e.g., Channel 21) from two different directions (e.g., North and West) into the same add/drop structure because they would "contend" or collide on the same internal fiber.
A Contentionless architecture (typically utilizing a Multicast Switch or MCS) allows the node to drop the same wavelength from different degrees simultaneously without interference. This is critical for high-availability mesh networks where a single transponder might need to receive a specific wavelength from a primary path and a backup path. Without contentionless capabilities, operators would have to carefully manage wavelength assignments across the entire network to ensure no two identical frequencies ever meet at the same drop structure, which significantly complicates planning and restoration.
NEW QUESTION # 23
Which of the following are the main reasons for fiber attenuation?
Answer: D
Explanation:
Scattering and absorption are the main reasons for fiber attenuation. Scattering occurs when light bounces off the sides of the fiber, while absorption happens when light is absorbed by the glass or other materials that make up the fiber. Chromatic dispersion (CD) and polarization mode dispersion (PMD) are also factors that can cause attenuation, but they are not the main causes. Small channel spacing can also cause attenuation, but it is a secondary factor and is only significant in certain cases.
