Which of the following technique is used for encapsulation?

None of these

a technique used in best-effort delivery systems to avoid endlessly looping packets.

a technique used by protocols in which a lower level protocol accepts a message from a higher level protocol and places it in the data portion of the low level frame.

One of the pieces that results when an IP gateway divides an IP datagram into smaller pieces for transmission across a network that cannot handle the original datagram size

All of these

You copy a configuration from a network host to a router's RAM. The configuration looks correct, yet it is not working at all. What could the problem be?

The IOS became corrupted after the copy command was initiated.

You copied the wrong configuration into RAM.

The copy did not override the shutdown command in running-config.

You copied the configuration into flash memory instead.
