You work as a network engineer at domain .com. Study the topology exhibit carefully. L3 switches domain .com 1 and domain .com 2 are in the backbone of the network. They are connected by a routed EtherChannel bundle consisting of eight Gigabit Ethernet ports. The routed link is represented as subnet X.0 in the diagram. Since X.0 is routed, it is not a VLAN trunk. How can spanning tree loops be prevented in the backbone of this network?
Exhibit:
A.
Since EtherChannel X is routed there are no spanning tree loops.
B.
Configure seven of the eight ports in the bundle as passive interfaces
C.
Configure UplinkFast on domain .com 1 and domain .com 2
D.
Disable Spanning Tree Protocol (STP) on domain .com 1 and domain .com 2
E.
Disable VLAN X on seven of the eight ports in the bundle
