A. A command that is available in every release of IOS.
B. A command that can be entered in any configuration mode.
C. A command that supports all protocols.
D. A command that is implemented in all IOS versions.
E. A command that is set once and affects the entire router.

Answer: E

When you enter global configuration mode and enter a command, it is applied to the running configuration file that is currently running in ram. The configuration of a global command affects the entire router. An example of a global command is one used for the hostname of the router.


Incorrect Answers:
A. Global configuration commands must be performed while in global configuration mode. For example, when you are in the interface configuration mode, you most likely will need to exit out into global mode to type in the commands.
B. Global commands do not necessarily support every protocol.
C. This is not necessarily true, since there are certain global commands that are supported on one feature set that are not on a different feature set of IOS.
E. Global commands can become outdated, and can be replaced by newer commands in the newer releases of IOS.
