Cisco CCIE Service Provider Optical Recertification Set 5

Selecting specific wavelengths from the signal and filtering only those out. ✘ Filtering out the required wavelengths and then regenerating the new signal. ✘ Terminating every wavelength and then regenerating the ones required. ✘ Efficiently amplify all signals in the same fiber ✔

Switched Fabric ✘ Arbitrated Loop ✘ Point to Multipoint ✘ Loop Channel bypass ✔ Point to Point ✔

Prisms ✘ Dielectric thin film interface filter ✘ Diffraction grating ✘ Semi-conductor filter ✔ Bragg Grating ✔

The Frame Relay network, to inform the DTE receiving the frame that congestion was experienced in the
path from source to destination ✘ The Frame Relay network, in frames traveling in the opposite direction from those frames that encounteredcongestion ✘ The receiving DTE, to inform the Frame Relay network that it is overloaded and that the switch shouldthrottle back ✘ The sending DTE, to inform the Frame Relay network that it is overloaded and that the switch should throttleback ✔ Any device that uses an extended DLCI address ✔
