Top of Form Host A has an IPaddress of 172.16.225.93, a mask of 255.255.248.0, and a default gateway of 172.16.224.1. Host A needs to send a packet to a new host whose IP is 172.16.231.78. Host A performs the ANDing operation on its address and subnet mask. What two things will occur? (Choose two.) |
| Host A will get a result of 172.16.224.0 from the AND process. |
| Host A will send on to the media a broadcast frame thatcontains the packet. |
| Host A will broadcast an ARP request for the MAC of the host 172.16.231.78. |
| Host A will change the destination IP of the packet to 172.16.224.1 and forward the packet. |
| Host A will encapsulate the packet in a frame with a destination MAC that is the MAC address associated with 172.16.224.1. |
