When a payload of data is passed through a network of routers to travel from a source host to a destination host, the IP source and destination addresses (in the IP header) change under the following circumstances:Question 14Select one:They change for every hop (sender to first router, first router to second router, etc.)They remain unchanged, even while passing through routersThey change at BGP (Border Gateway Protocol) gatewaysThe destination address remains unchanged, but the source address changes at each router

What header address information does a router change in the information it receives froman attached Ethernet interface before information is transmitted out another interface?A. only the Layer 2 destination addressB. only the Layer 3 source addressC. only the Layer 3 destination addressD. the Layer 2 source and destination address

Which of the following is true of the Ethernet header.Group of answer choicesAs routers move a packet from one LAN to the next, they remove their MAC address from the destination field. The source field, which contains the MAC address of the originating computer does not change.As routers move a packet from one LAN to the next, they remove both the source and the destination MAC address from the packet and replace those values with two new values. The router's MAC becomes the source address and the MAC address of the next device along the route becomes the destination address.As routers move a packet from one LAN to the next, they do not alter the source or destination MAC address (the do change the source/destination IP address).

The _______ address in the header of a packet in a datagram network normally remains the same during the entire journey of the packet.a.Sourceb.Nonec.Destinationd.Local

If a sending host wants to send a packet to another host on the same network, the logical address that must be mapped to a physical address is _____?Question 2Select one:The destination IP address in the header.The IP address of the router found in the routing table.The ISP router's routing table.None of the above.

Which of the following are true about a LAN-connected TCP/IP host and its IP routing (forwarding) choices? (Choose two answers)Question 9Select one or more:The host sends packets to its default gateway if the destination IP address is in a different class of IP network than the host.The host sends packets to its default gateway if the destination IP address is in the same subnet as the host.The host always sends packets to its default gateway.The host sends packets to its default gateway if the destination IP address is in a different subnet than the host.
