On a campus network, if two switches are directly connected through three physical links, you...

STP and link aggregation are not mutually exclusive technologies. They solve different problems and can coexist on the same switch. Link aggregation combines multiple physical Ethernet links into a logical Eth-Trunk, increasing available bandwidth and providing member-link redundancy. STP or a related spanning-tree protocol prevents Layer 2 loops by calculating a loop-free active topology and can treat an Eth-Trunk as a logical interface. In a well-designed campus network, several physical links between two switches may first be aggregated into one Eth-Trunk, while STP operates over that logical link together with other Layer 2 paths. Conversely, if separate redundant links are not aggregated, STP may block one or more paths to prevent a loop. Choosing link aggregation can use parallel member links more efficiently than allowing STP to block individual links, but enabling one function does not prohibit use of the other elsewhere on the device. Therefore, the assertion that only STP or link aggregation can be configured on a device at one time is incorrect. The verified answer is FALSE, option B.
