  The graph represents optical signal power versus wavelength measurement from 1550nm to 1560nm. What is the gain tilt of all of the seven channels?

  A. 10dB
  B. i5dB
  C. 20dB
  D. 25dB
  E. 30dB

• Question 46:

  EIGRP applies the principle of Feasible Successor (FS) in resolving a new path to a lost route. What statement regarding the FS is correct?

  A. Information is stored for the FS as part of the Link-State Routing updates forwarded for EIGRP.
  B. EIGRP estimates the FS from each neighbor for each network after an exchange of database information during the normal update process. It uses this information for path selection when a route is lost.
  C. When EIGRP is notified that a route is lost, it will always send requests to each neighbor for ways to reach the lost route. The neighbor that returns the best path will qualify as the FS.
  D. EIGRP nominates a central router as the FS for all lost routes during configuration.
  B. EIGRP estimates the FS from each neighbor for each network after an exchange of database information during the normal update process. It uses this information for path selection when a route is lost.

  A. Polarization-mode dispersion
  B. SelF. phase modulation
  C. Cross-phase modulation
  D. Four-wave mixing
  A. Polarization-mode dispersion
