Question 4 of 347
Which command prompt indicates that you are in operational mode?
    Correct Answer: D

    In many networking devices, particularly those using Juniper's Junos OS, the command prompt for operational mode is denoted by the '>' symbol. This prompt (user@router>) indicates that the device is ready to accept operational commands, which are used for tasks such as monitoring and diagnostic queries. The other prompts, such as '&', '#', and '%', are not used to indicate operational mode.
