NEW QUESTION # 39
Which statement is correct about node synchronization?
Answer: D
Explanation:
Node synchronization is a process of keeping the NFM-T database in sync with the nodes in the network. The synchronization process will download all the items from the node, including NE parameters, ports, alarms, internal links, etc., to the NFM-T database. This ensures that the NFM-T database is up to date and the network is running efficiently.
NEW QUESTION # 40
Is it possible to mix PSS-24x and PSS-8x shelves In an SWDM configuration?
Answer: A
Explanation:
No, it is not possible to mix PSS-24x and PSS-8x shelves in an SWDM (Short Wavelength Division Multiplexing) configuration. The two shelves are not compatible, and cannot be used within the same node.
NEW QUESTION # 41
Which of the following statements about coherent transmission in WDM technology is TRUE?
Answer: A
Explanation:
Comprehensive and Detailed Explanation From Nokia Optical Networking Fundamentals:
Coherent transmission represents a massive leap in optical technology, moving beyond simple "on-off keying" (Intensity Modulation) to more complex modulation formats like QPSK or 16-QAM. A fundamental requirement of a coherent receiver is the ability to recover and track the carrier phase information of the incoming signal. This is achieved by using a Local Oscillator (LO) laser at the receiver that interferes with the incoming signal, allowing the receiver to extract phase and polarization data.
Unlike legacy 10G direct-detection systems, coherent systems (like Nokia's PSE-V engine) perform Digital Signal Processing (DSP) to electronically compensate for impairments. This makes Option D false, as physical Dispersion Compensation Modules (DCMs) are actually detrimental and usually removed in coherent networks. Option B is incorrect as coherent transmission is designed for Single-Mode Fiber (SMF). Option C refers to Flex-grid technology; while coherent signals often use Flex-grid, the defining characteristic of coherent technology is the phase-sensitive detection at the receiver.
NEW QUESTION # 42
A user needs to check for interface details against the commands is the correct one?
Answer: D
Explanation:
show interface 11starla 1/17/L1 detail is the correct command to check for interface details. This command will display detailed information about the specified interface, including its status, configuration, and statistics.
NEW QUESTION # 43
A user needs to retrieve the active alarm list from a network element. Which command should be issued through an 1830 PSS CLI?
Answer: D
Explanation:
Comprehensive and Detailed Explanation From Nokia Optical Networking Fundamentals:
The Nokia 1830 PSS uses a Command Line Interface (CLI) that is distinct from the Nokia SR-OS used in routers. For technicians performing local maintenance or troubleshooting via a serial or SSH connection to the Shelf Controller (EC), the command to view the current status of the network element's alarms is show fault-database or the shorthand alm.
When the alm command is executed, the system displays a table containing all active alarms, their severity (Critical, Major, Minor, or Warning), the timestamp of the occurrence, and the specific object (e.g., a specific port or card) that is reporting the fault. This is the primary method for "Layer 0" local troubleshooting. While management software like WS-NOC provides a Graphical User Interface (GUI) to view these alarms, knowing the CLI command is essential for field operations where a connection to the central management system might not be available. Option B, C, and D are incorrect as they do not follow the specific syntax of the 1830 PSS CLI environment.
