NEW QUESTION # 41
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 # 42
What is the metro area network?
Answer: D
Explanation:
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.

NEW QUESTION # 43
Which application generates the commissioning file(s)?
Answer: C
Explanation:
The CPB (Commissioning Parameter Builder) application is used to generate the commissioning files for a Nokia 1830 Photonic Service Switch (PSS-1). The CPB application allows the user to create multiple commissioning files [1][2], which can be used to configure a variety of different features on the device. The CPB also allows users to view, edit and modify the commissioning files before they are uploaded to the device. The NSP (Network Service Platform) and EPT (Element Provisioning Tool) are used to manage the devices and network elements within the network, but do not generate commissioning files.
NEW QUESTION # 44
Which of the following statements best describes the definition of PCT?
Answer: A
Explanation:
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.
NEW QUESTION # 45
Which of the following is NOT a troubleshooting functionality of the Wavelength Tracker?
Answer: D
Explanation:
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.
