Click the Exhibit button. In the DCN connection shown in the exhibit, all non-GNE nodes are located on different subnets from the GNE. There are no static routes or external OSPF on any elements. CTC Workstation and GNE have Cisco Router as their default gateway.
Can the CTC workstation see the entire SONET network?（）
A. Yes, but only if OSPF is enabled around the ring.
B. Yes, because the GNE will only serve as a proxy-ARP for elements on the same subnet.
C. Yes, but only if the router's address is entered as a static route in the non-GNE elements.
D. Yes, because the GNE will serve as a proxy-ARP for all elements, regardless of their subnets.
A. line timing
B. loop timing
C. internal timing
D. through timing
E. external timing
