Based on the network shown in the graphic, which option contains both the potential networking problem and the protocol or setting that should be used to prevent the problem?

A. routing loops, hold down timers

B. switching loops, split horizon

C. routing loops, split horizon

D. switching loops, VTP

E. routing loops, STP

F. switching loops, STP

Correct Answer: F

Section: Switching

Explanation

Explanation/Reference:

There are no routers, so no routing loops. We do have redundant links between switches, so we have switching loops. The Spanning Tree Protocol (STP) prevents

loops by disabling frame forwarding on some of the switches’ ports.
