In the exhibit, you have a DWDM ring between two sites that are approximately 75 km apart for each (east/ west) span of the ring. The DWDM ring has been constructed so that there is failover from the active span to the passive span in the event of a failure of the active span. These optical multiplexers will drop frames during the 50 ms switch from Span 1 to Span 2. You do not want to suffer an IFCC during a ring failover. Which two configurations will prevent IFCC from occurring? (Choose two.)
