최신 Nokia Optical Network Professional 4A0-205 무료샘플문제 (Q51-Q56):

질문 # 51
Where is the OPS card equipped to provide the optical channel protection?

A. Between the transponder and the amplifiers
B. Between the transponder and the filter
C. Before the transponder, on the client side, towards the external device
D. Between the filters and the amplifiers

정답：A

설명：
According to the Nokia's 1830 Photonic Service Switch (PSS) product documentation, the Optical Protection Switching (OPS) card is equipped in the transponder and is responsible for providing optical channel protection between the transponder and the amplifiers. The OPS card monitors the optical signal and switches to a pre-configured protection path in case of signal degradation or loss.

질문 # 52
With reference to trails and services, which of the following sentences is correct?

A. Services are transported over trails; that is, services are clients with respect to trails.
B. A trail can interconnect three ports, while a service always two.
C. Trails are transported over services; that is, trails are clients with respect to services.
D. A service is always associated to a single wavelength, while a trail can involve multiple wavelengths.

정답：A

설명：
Services are transported over trails; that is, services are clients with respect to trails. A service is a logical connection that is used to transport data from one point to another. It is created over a trail, which is a physical connection that is established by using multiple wavelengths. As such, services are clients with respect to trails, as they are transported over them.

질문 # 53
Which of the following statements about Optical Add/Drop Multiplexers (OADMs) is FALSE?

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

정답：C

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 # 54
What is the metro area network?

A. The metro area network is located between access and core domains.
B. The metro area network is that portion of network that passes through a city to provide connections to several customers.
C. The metro area network is made of OCS/SWDM nodes only, as no pure photonic nodes are used here.
D. The metro area network is located in between two access area networks and made of photonic nodes only (no OCS/SWDM nodes are used there).

정답：B

설명：
The Metro Area Network (MAN) is a telecommunications network that spans a metropolitan area and connects multiple local area networks (LANs) or business networks together. It typically covers an area that is larger than a LAN but smaller than a wide area network (WAN). The purpose of a MAN is to provide a high-bandwidth, low-latency communication infrastructure for businesses and other organizations in a metropolitan area.

질문 # 55
Which of the following is NOT a troubleshooting functionality of the Wavelength Tracker?

A. Detecting unexpected or missing channels.
B. Performing channel power monitoring.
C. Testing a node's internal fiber connectivity before service provisioning.
D. Tracing a service along an optical path.

정답：C

설명：
Comprehensive and Detailed Explanation From Nokia Optical Networking Fundamentals:
The Nokia Wavelength Tracker is a unique and powerful technology used within the 1830 PSS portfolio to provide "layer 0" visibility. It works by embedding unique optical signatures (keys) onto each wavelength at the source (transponder). These signatures allow the system to identify and monitor individual channels as they traverse the optical network without the need for expensive Optical Spectrum Analyzers (OSAs) at every site.
Specifically, the Wavelength Tracker enables tracing a service along its path by identifying these unique keys at various monitoring points. It also excels at channel power monitoring, as it can measure the power level of each specific wavelength independently. Furthermore, it is instrumental in detecting unexpected or missing channels (ghost signals or misrouting) by comparing the detected keys against the expected provisioning data in the management system. However, it is not used for testing a node's internal fiber connectivity before service provisioning. Internal fiber connectivity is typically verified during the commissioning phase using the Commissioning and Power Balancing (CPB) tool within WS-NOC or through manual physical inspection and "fiber-it" procedures. Wavelength Tracker requires an active, keyed optical signal to function, which generally exists only during or after the service provisioning stage.
