- 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
Answer: Option F.
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.
