In Cisco IOS, which symbol denotes privileged EXEC mode?

In Cisco IOS, privileged EXEC mode is indicated by the '#' symbol. When a user enters privileged EXEC mode from user EXEC mode, the prompt changes to include this symbol, indicating that the user has elevated privileges to execute a wider range of commands, including configuration commands and access to all commands available in the operating system.

This is an important aspect of Cisco IOS, as it establishes the user's ability to perform more advanced network management and troubleshooting tasks. In contrast, user EXEC mode, which is indicated by the '>' symbol, has limited command capabilities and is primarily used for basic command execution and view-only access to certain information about the device.

The other options listed, such as (config)# and (config), are indicative of the global configuration mode where the user can make changes to the device's configuration but are not relevant to identifying privileged EXEC mode specifically. This makes it crucial to recognize the '#' symbol as the definitive marker of privileged EXEC mode in Cisco IOS.
