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?
You copied the wrong configuration into RAM.
You copied the configuration into flash memory instead.
The copy did not override the shutdown command in running-config.
The IOS became corrupted after the copy command was initiated.
Answer: Option
Explanation:
Since the configuration looks correct, you probably didn't screw up the copy job. However, when you perform a copy from a network host to a router, the interfaces are automatically shut down and need to be manually enabled with the no shutdown command.
