You are designing an optical network. Your goal is to ensure that your design contains the highest
degree of resiliency. In which two ways will you leverage a wavelength-switched optical network
solution in your network design? (Choose two.)

A.
a wavelength-switched optical network assigns routing and wavelength information

B.
a wavelength-switched optical network takes linear and nonlinear optical impairment calculation
into account

C.
a wavelength-switched optical network guarantees restoration based strictly on the shortest
path available

D.
a wavelength-switched optical network eliminates the need for dispersion compensating units in
a network
