A failure in the Spanning Tree Algorithm can lead up to which two issues? (Choose two)
Decrease in CPU utilization.
A bridging loop.
MAC database instability.
Interface errors increase.
Loss of VLAN information.
When there is more than one Layer 2 path between two end points, a switch (bridge) loop is created. The loops will create broadcast storms which will flood the network with multiple copies of the same unicast. Switching loops can also cause false entries in a switch's MAC database, causing endless unicast frames to be distributed thought the network.
