JN0-106 Operational Monitoring and Maintenance Practice Question
A network administrator needs to check the current software version and hardware model of a Juniper device. Which command should the administrator use?
⚠ Common exam trap
Watch out — candidates often confuse hardware inventory commands like show chassis hardware with the command that provides both software version and hardware model.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
show version
The show version command is specifically designed to display the Junos OS software version and hardware model. It provides a concise summary that includes the hostname, model, Junos version, and uptime. The other commands either focus on hardware details or are invalid, making show version the correct choice for this scenario.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
show version
Why this is correct
The show version command displays the Junos OS software version, hardware model, and other system information such as uptime and build date. It is the standard command to quickly obtain the device's software and hardware details, making it ideal for inventory and compatibility checks.
- ✗
show system information
Why it's wrong here
The show system information command is not a valid Junos operational command. The correct command to display system information including software version is show version. This option is a distractor that sounds plausible but does not exist in Junos.
- ✗
show configuration version
Why it's wrong here
The show configuration version command is not a valid Junos command. Configuration version information is typically viewed using show system commit or similar, but that does not provide software version. This option is incorrect and would not yield the desired information.
- ✗
show chassis hardware
Why it's wrong here
The show chassis hardware command provides detailed information about the physical hardware components, such as chassis, power supplies, and fans, but it does not display the Junos OS software version. While useful for hardware inventory, it does not meet the requirement to check the software version.
