Refer to the exhibit. How does the switch process the Ethernet frame?

Switches only drop frames under specific conditions such as port security violations or VLAN mismatches, not when the destination MAC is known and valid.

The exhibit's MAC address table contains an entry mapping the destination MAC address to port3, so the switch performs a unicast forward directly to port3 rather than flooding, filtering, or dropping the frame.

Filtering occurs when the source and destination MAC are on the same port, preventing a loop, which is not the case when a learned destination entry exists in the table.

Flooding (unknown unicast) only happens when the destination MAC is absent from the MAC address table, not when a matching entry already exists.
