Answer: F
Explanation: The Spanning-Tree Protocol (STP) prevents loops from being formed when switches or
bridges are interconnected via multiple paths. Spanning-Tree Protocol implements the
802.1D IEEE algorithm by exchanging BPDU messages with other switches to detect
loops, and then removes the loop by shutting down selected bridge interfaces. This
algorithm guarantees that there is one and only one active path between two network
devices.
