Nokia Optical Networking Fundamentals Sample Questions (Q44-Q49):

NEW QUESTION # 44
Which of the following statements about coherent transmission in WDM technology is TRUE?

A. Coherent systems need carrier phase information at the receiver.
B. At each receiver, a dispersion compensation unit is often necessary, depending on the fiber length.
C. Only multi-mode fibers can be used with coherent transmissions.
D. The channel allocation is flexible, according to the channel size of the signals.

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 # 45
Is it possible to modify node parameters within the edit EPT menu?

A. Yes, the user can apply manual changes directly from this view
B. Yes, but the user can modify only the node name and location
C. No, this view is used to display a close-up view of the node
D. Yes, the user can apply manual changes but only for non-GMPLS nodes, as the control plane reserves node resources not editable by the user

Answer: D

Explanation:
Yes, the user can apply manual changes but only for non-GMPLS nodes, as the control plane reserves node resources not editable by the user. The edit EPT menu allows the user to view information about a node but is not used to modify node parameters. The user can only apply manual changes to non-GMPLS nodes, as the control plane reserves node resources which cannot be modified by the user.

NEW QUESTION # 46
A user needs to check for interface details against the commands is the correct one?

A. config card 11star1a interface 1/17 detail
B. show interface 11starla 1/17/L1 detail
C. 11starla 1/17 port-detail
D. config interface detail 1/17/L1

Answer: B

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 # 47
Which statement is correct about node synchronization?

A. Node synchronization is executed to align the time of the node to the time of the NFM-T platform
B. Node synchronization is executed to test the reachability of a node
C. Full synchronization retrieves the correlated alarms from the node
D. Full synchronization retrieves all items from the node (NE parameters. Ports, Alarms, Internal Links, etc)

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 # 48
Which of the following is an example of optical protection mechanism?

A. GR and SBR combined
B. OSNCP (e.g., via Y-cable or OPS card)
C. GMPLS-enabled SBR
D. Optical regeneration (e.g., back-to-back regeneration)

Answer: B

Explanation:
It can be implemented through the use of a Y-cable or an optical protection switch (OPS) card, which allows for the switching of traffic to a secondary path in the event of a failure on the primary path. This type of protection is commonly used to protect against fiber cuts and other types of physical layer failures in the optical transport network.
