JN0-106 Junos OS Fundamentals Practice Question
An engineer wants to view the current active configuration file that the device is using. Which command displays this information?
⚠ Common exam trap
Watch out — candidates often confuse 'show configuration' with 'show configuration | display set' or think 'show system commit' shows the active config, when in fact it only shows commit history, not the current running configuration.
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 configuration
The 'show configuration' command displays the current active configuration that the device is using, which is the committed configuration stored in /config/juniper.conf.gz. This command reads the active configuration file directly from the file system, showing the exact operational configuration that Junos applies to the device.
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 configuration candidates
Why it's wrong here
Invalid command; candidates are shown via 'show | compare' or similar.
- ✗
show system commit
Why it's wrong here
This shows the commit log, not the active configuration.
- ✓
show configuration
Why this is correct
This displays the active committed configuration.
- ✗
show configuration | display set
Why it's wrong here
A valid command that displays the current active configuration in 'set' format, but the question asks for the command that displays the configuration information. While 'show configuration | display set' shows the active configuration, the most direct command without a pipe is 'show configuration', making option C the correct answer.
