Nokia Optical Networking Fundamentals - 4A0-205 模擬練習

A. Wavelength Tracker monitoring points are settled on IRDMxx line interfaces only.

B. Wavelength Tracker monitoring points are settled on ITL mux interfaces and on OTs line interfaces.

C. Wavelength Tracker monitoring points are settled on IRDMxx and OTs line interfaces.

D. Wavelength Tracker monitoring points are settled on IRDMxx line interfaces and on CWR CLS interfaces.

A. The ControlPlane status column on the node list displays the GMRE status for the selected node

B. The GMRE reachability can be tested via ping request from NFM-T

C. The GMRE activation status is reflected on the color of the icon representing the node

D. The GMRE activation status is reported in the supervision state column on the node list

A. These windows correspond to three different minimum and maximum optical power levels used for optical transmission.

B. These windows are three different wavelength intervals where the WDM optical transmission occurs.

C. Different optical transmission windows correspond to different safety requirements and rules for the related lasers operating with these windows.

D. These three windows are three different angles of incidence of the light injected by the laser into the fiber.

A. The NSP package should be downloaded from the Nokia website and properly licensed for the specific workstation to be used.

B. A browser and the NSP IP address; and from the landing page, the NSP application should be downloaded and launched.

C. A browser and the NSP IP address. Then, a browser plugin needs to be installed and the laptop rebooted before the NSP can be correctly reached.

D. A browser, the NSP IP address, and the credentials to access the web-based interface (WebUI).

A. Yes, although this is not happening in case of GMPLS-enabled nodes because existing slots cannot change as they are controlled by another manager (GMRE).

B. It depends, the user is prompted to choose whether to delete or leave the previously designed elements.

C. Not the design is always progressive, on top of the previous design.

D. Yes, they are but only the first time the command is launched as - for future design phases - the existing packs need to keep the same slotting.

A. The metro area network is made of OCS/SWDM nodes only, as no pure photonic nodes are used here.

B. The metro area network is located between access and core domains.

C. The metro area network is that portion of network that passes through a city to provide connections to several customers.

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).

A. It is the range between the receiver overload power and its sensitivity.

B. It is the maximum receiver power to prevent an overload.

C. It is the range between the maximum transmit power and the minimum transmit power.

D. It is the minimum power to be received for a given BER.
