If you have a fiber cut on all four fibers between nodes C and D in the following diagram put the
events listed below in correct chronological sequence.
1. node A loops back traffic in the direction of node E
2. node D initiates a line switch and signals the fact in the K2 byte
3. node C loops back traffic in the direction of node B
4. both sides switch traffic to the protect channel and the circuit is restored in less than 50 ms
5. nodes C detects the loss of signal and signals the fact in the K1 byte

The diagram shows a campus with a L2 switched backbone. The backbone has a single VLAN (=
subnet) with no loops. The links into the backbone are routed interfaces, not VLAN trunks. Switch
X is the STP root of the core VLAN and switch Y is the standby root. The connection between X
and Y is an EtherChannel. The network architect wants to add more redundancy by connecting
the L3 switches in the distribution layer to both X and Y. What best describes that plan?
