Which mechanisms can be put in place to increase network survivability?

• A.Protection, where backup resources are allocated upon failure; or restoration, where backup resources are pre-allocated and reserved
• B.Protection, where backup resources are pre-allocated and reserved; or restoration, where each trail can be recovered thanks to a 1+1 protection mechanism
• C.Protection, where backup resources are allocated upon failure; or restoration, where each trail can be recovered thanks to a 1+1 protection mechanism
• D.Protection, where backup resources are pre-allocated and reserved; or restoration, where backup resources are allocated upon failure.

WDM allows transmission systems to:

• A.Share a single signal among multiple fibers doing load balancing, and thus increasing the reliability of the optical transmission
• B.Increase the bit rate of each client signal by spreading it over multiple wavelengths
• C.Transport multiple signals transparently, onto several wavelengths, all together over one single fiber
• D.Allocate different signals to different time slots

Where can the user set the long-haul WT decoder parameter, when designing a network with EPT?

• A.In the audit menu
• B.In the network parameters
• C.In the optimization parameters
• D.In the NE parameters

Is it possible to select the fiber type independently for each segment while designing a network in EPT?

• A.No, as the fiber type is selected for links only and it's one for whole design
• B.No, a unique type is allowed per design for all segments
• C.Yes, during the link creation through the wizard
• D.Yes, during the segment creation phase or editing

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

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