최신 Nokia Optical Network Professional 4A0-205 무료샘플문제 (Q59-Q64):

질문 # 59
Which of the following are the main reasons for fiber attenuation?

A. Chromatic dispersion (CD) and polarization mode dispersion
B. Refraction and reflection
C. Scattering and absorption
D. Small channel spacing

정답：C

질문 # 60
Which of the following statements about Optical Add/Drop Multiplexers (OADMs) is FALSE?

A. OADMs allow the user to pass-through specific services at the wavelength optical level (express channels).
B. OADMs always require O-E-O conversion when passing-through optical channels.
C. OADMs allow the user to terminate specific services through transponders.
D. There are two main general classes of OADMs: FOADMs and ROADMs.

정답：B

설명：
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.

질문 # 61
What is the OAMP LAN interface?

A. It is an RJ-45 interface (common Ethernet port) used to connect one or more client ports (e.g., 1Gb/s or legacy 100Mbit/s client flows)
B. It is an RJ-45 interface (a common Ethernet port) used to export active alarms to an external device, typically equipped with several LEDs
C. It is an RJ-45 interface (a common Ethernet port) that has to be configured with an IP address for node reachability and management
D. It is an RJ-45 interface (a common Ethernet port) used for cascading 1830 PSS nodes (e.g., external shelves)

정답：C

설명：
It is an RJ-45 interface (a common Ethernet port) that has to be configured with an IP address for node reachability and management. This interface is used to connect the OAMP node to the LAN, allowing it to be managed and monitored remotely.

질문 # 62
Which of the following statements best describes the definition of PCT?

A. A tool supporting zero-touch power management on PSS-32 equipment.
B. A tool supporting nodes' automatic provisioning on NFM-T.
C. A tool supporting external links autodiscovery on NFM-T.
D. A tool to validate internal fiber connectivity on CDC-F 2.0 nodes.

정답：D

설명：
Comprehensive and Detailed Explanation From Nokia Optical Networking Fundamentals:
The Photonic Connectivity Tool (PCT) is a specialized utility within the Nokia 1830 PSS ecosystem designed specifically for modern, complex node architectures. As networks evolved toward CDC-F (Colorless, Directionless, Contentionless with Flex-grid), the internal fiber cabling within a single node became significantly more complex, involving numerous connections between WSS modules, Multicast Switches (MCS), and amplifiers.
The PCT is used to validate internal fiber connectivity, ensuring that the physical "patching" matches the intended design before service provisioning begins. It leverages the OSRP (Optical Signal Routing Protocol) or specialized control plane mechanisms to verify that light can flow through the internal cross-connects as expected. This tool is essential for reducing human error during the installation of high-degree ROADM sites, where dozens of internal fibers must be correctly mapped to ensure the "Directionless" and "Contentionless" features function without blocking.

질문 # 63
How can a mesh network be upgraded so that more services can be transported?

A. Upgrading the network to coherent transmission is the only effective way to enable more bandwidth to the existing mesh network.
B. The Protection and Restoration Combined (PRC) mechanism can enable more bandwidth but only for the protected services.
C. Upgrading link capacity and/or installing new links provides more bandwidth to the existing mesh network.
D. Configuring new WSS cards is the most effective way to give flexibility and network bandwidth to an existing mesh network.

정답：C

설명：
Comprehensive and Detailed Explanation From Nokia Optical Networking Fundamentals:
While technologies like WSS (Wavelength Selective Switches) and coherent transmission (100G/200G/400G+) significantly improve the efficiency and reach of a network, the most direct way to increase the total transportable volume of services in a mesh topology is to upgrade link capacity or install new physical links. In Nokia optical planning, upgrading link capacity typically involves moving from a lower-rate system (like 10G) to a higher-rate system (like 100G or 400G) or increasing the number of available wavelengths by expanding from a 40-channel to an 80-channel or 96-channel C-band system.
Adding new links (new fiber spans) creates more degrees in the mesh, providing more paths for traffic and increasing the overall aggregate bandwidth of the network. Option A refers to flexibility (ROADM functionality) rather than raw capacity. Option B (PRC) relates to survivability and availability, not capacity expansion. While Option C (coherent transmission) is a powerful method for increasing capacity per wavelength, it is not the "only" way, as adding more fiber (spatial multiplexing) or more channels (spectral density) are also primary methods for scaling a mesh network to handle more services.
