Selected Answer: C
C. 300 seconds Explanation: By default, an EX Series switch retains a learned MAC address in the bridge table for 300 seconds (5 minutes). This is known as the MAC address aging time. If the switch receives no traffic from that MAC address within the aging time, the MAC address is removed from the bridge table. The default aging time can be modified if required.
