Refer to the exhibit. Host A is connected to the LAN, but it cannot get access to any resources on the Internet. The configuration of the host is shown in the exhibit. What could be the cause of the problem?

The host subnet mask is incorrect.

The default gateway is a network address.

The default gateway is a broadcast address.

The default gateway is on a different subnet from the host.

What two things will happen if a router receives an ICMP packet which has a TTL value of 1 and the destination host is several hops away? (Choose two.)

The router will discard the packet.

The router will decrement the TTL value and forward the packet to the next router on the path to the destination host.

The router will send a time exceeded message to the source host.

The router will increment the TTL value and forward the packet to the next router on the path to the destination host.

The router will send an ICMP Redirect Message to the source host.
