The MAC address table on a layer 2 switch is shown in the figure.

When the switch receives a frame with a destination MAC address of 00-13-72-8E-4B-C1 from the E1/0/2 interface, the switch will ______ the frame.

On the MSR router, by default, the configuration file is suffixed with ______.

To configure a static route on the router. It is known that the destination address is 192.168.1.0, the mask is 20 bits, the outgoing interface is GigabitEthernet0/0, and the outgoing interface IP address is 10.10.202.1, so which of the following configurations is correct?

Create an aggregate port with port Ethernet1/0/1 and ID 2 on the S3610 switch. The correct command is ______.

There are two hops from the source device to the destination device. Use the tracert command to detect the path. When the first hop is detected, the source device sends a UDP packet with a TTL of 1 to a larger port of the destination device. When the packet reaches the middle hop, the TTL will change to 0, so the device responds to the source device. Respond to an ICMP______ message.
