Which command would you use to view the current system software version on a Juniper device?

• A. show version
• B. show software
• C. show system
• D. show configuration

Answer: (A)

The command to view the current system software version on a Juniper device is "show version." This command provides detailed information about the device's hardware and software, including the specific version of the Junos operating system that the device is running. When you enter this command in the CLI (Command Line Interface), it will return the version number along with other relevant system information such as the router's model and uptime. The other options do not provide the specific software version information. The "show software" command typically relates to software packages and updates rather than the current running version. The "show system" command can provide details about various system aspects, but not specifically the software version. The "show configuration" command displays the configuration settings of the device rather than details about the software or hardware versions. Therefore, using "show version" is the most direct and appropriate choice for checking the system software version.
