NEW QUESTION # 20
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 # 21
How many PM bins can be stored, for each data collection point, on PSS systems?
Answer: B
Explanation:
Comprehensive and Detailed Explanation From Nokia Optical Networking Fundamentals:
Performance Monitoring (PM) is critical for maintaining the health of a Nokia 1830 PSS network. The system collects data such as FEC corrected bits, optical power levels, and ODU-layer errors. According to Nokia's standard node management architecture, each data collection point (such as an optical port or an ODU termination point) stores a specific number of historical "bins" locally on the card or the shelf controller.
The standard storage capacity for these PM statistics is 33 x 15-minute bins (covering the last 8 hours and 15 minutes of granular data) and 8 x 1-day bins (covering the last week of daily totals). Additionally, there is 1 raw bin which contains the "current" accumulating data that has not yet been shifted into a completed 15-minute or 24-hour historical bin. This allows network operators using WS-NOC (WaveSuite Network Operations Center) to retrieve recent historical performance data directly from the NE (Network Element) even if the management system was temporarily disconnected. If longer-term history is required, the management system must be configured to poll and archive these bins into its own database before they are overwritten on the hardware.
NEW QUESTION # 22
Which of the following statements about the ODUk unit is TRUE?
Answer: B
Explanation:
Comprehensive and Detailed Explanation From Nokia Optical Networking Fundamentals:
In the Optical Transport Network (OTN) hierarchy, the ODUk (Optical Data Unit of order k) is the fundamental unit for electronic grooming and switching. Unlike the OTUk layer, which is tied to a specific physical optical interface and includes the Forward Error Correction (FEC), the ODUk layer is "path-oriented." This means that in a switched WDM system like the Nokia 1830 PSS-24x, the ODUk containers can be switched across a backplane from one line card to another without needing to deconstruct the entire optical signal.
To clarify the other options: Option A is false because FEC is part of the OTUk (Transport Unit) layer. Option C is false because ODUk processing is entirely electrical (O-E-O must occur to access the ODUk overhead). Option D is false because the OPU (Optical Payload Unit) is actually the "first" container where the client signal is mapped; the ODUk then wraps around the OPU to add path-level monitoring and maintenance signals. Therefore, the ODUk acts as the "virtual container" that allows the network to manage services end-to-end across multiple optical spans.
NEW QUESTION # 23
Which of the following statements about Optical Add/Drop Multiplexers (OADMs) is FALSE?
Answer: C
Explanation:
Comprehensive and Detailed Explanation From Nokia Optical Networking Fundamentals:
In the context of the Nokia 1830 PSS (Photonic Service Switch) and general WDM principles, the statement that OADMs always require O-E-O (Optical-Electrical-Optical) conversion for pass-through channels is fundamentally incorrect. The primary purpose of an OADM is to provide the ability to "add" or "drop" specific wavelengths while allowing other wavelengths (known as express or pass-through channels) to continue through the node entirely in the photonic domain.
By remaining in the optical layer, these express channels avoid the latency and cost associated with O-E-O conversion. FOADMs (Fixed OADMs) use static filters to achieve this, while ROADMs (Reconfigurable OADMs) use Wavelength Selective Switches (WSS) to dynamically route traffic. O-E-O conversion only occurs at the transponder or muxponder level when a service is terminated (dropped) or initiated (added) to convert the client signal into a compliant DWDM wavelength. Therefore, the efficiency of an optical network relies on the fact that pass-through traffic stays as light, bypassing the need for electrical processing at every node.
NEW QUESTION # 24
What does it take to get connected to the NSP platform?
Answer: D
Explanation:
To get connected to the Nokia Service Platform (NSP) platform, you need a browser and the NSP IP address. Then, you need the credentials to access the web-based interface (WebUI) for the NSP platform. Once you have these, you can access the NSP platform from a web browser.
