JN0-106 Junos OS Fundamentals Practice Question
A company wants to implement best practice for password recovery on Juniper devices to avoid service disruption. Which of the following is the recommended method?
⚠ Common exam trap
Candidates often confuse Juniper's single-user mode recovery with Cisco's password recovery process, which often involves a configuration register change and may require a factory reset; Juniper's method is designed to preserve the configuration, while Cisco's recovery can sometimes erase the startup configuration if not done carefully.

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
✓
Boot the device into single-user mode from the console and reset the root password
Booting the device into single-user mode from the console is the standard, secure method for password recovery on Juniper devices. This process allows an administrator with physical console access to reset the root password without affecting the running configuration or causing service disruption, as the device boots with a minimal kernel and does not load the full configuration.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Perform a factory reset to default configuration
Why it's wrong here
Factory reset wipes all settings, causing unnecessary downtime and data loss.
- ✓
Boot the device into single-user mode from the console and reset the root password
Why this is correct
This is the standard Juniper password recovery procedure, allowing password reset without affecting configuration.
- ✗
Use SNMP to modify the password field in the configuration
Why it's wrong here
SNMP cannot change passwords; it is for monitoring and basic configuration, not authentication.
- ✗
Contact JTAC to remotely reset the password
Why it's wrong here
JTAC cannot remotely reset passwords; physical access or out-of-band management is required.
