- A
Set the class (set system login user <name> class <class>), then set the authentication method to plain-text-password (set system login user <name> authentication plain-text-password), then commit the configuration.
This is the correct order. First, set the class to define the user's privilege level. Then, set the authentication method to plain-text-password, which will prompt for a password. Finally, commit to apply the configuration.
- B
Set the authentication method to plain-text-password first, then set the class, then commit the configuration.
Why wrong: This order is incorrect. Setting authentication before class is not a supported sequence in Junos; the user must first have a class assigned. Attempting to set authentication without a class may result in an error or ineffective configuration.
- C
Set the class, commit the configuration, then set the authentication method to plain-text-password.
Why wrong: This is incorrect because committing before setting authentication leaves the user without a password, making it impossible to log in.
- D
Set the authentication method to plain-text-password, commit the configuration, then set the class.
Why wrong: This is incorrect because committing before setting the class results in an incomplete user configuration; the user would not have a privilege level.
How to Configure a User Account in Junos
This JNCIA-JUNOS practice question tests your understanding of junos os fundamentals. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. A key principle to apply: user account configuration. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.

Correct answer & explanation
Set the class (set system login user <name> class <class>), then set the authentication method to plain-text-password (set system login user <name> authentication plain-text-password), then commit the configuration.
The correct order for configuring a user account in Junos is to first set the class to define the user's privilege level, then set the authentication method (e.g., plain-text-password), and finally commit the configuration. Option A follows this sequence. Option B is incorrect because setting authentication before class can lead to a configuration error; Junos requires the class to be set first. Option C is wrong because committing before setting authentication leaves the user without a password, preventing login. Option D is incorrect because committing before setting the class results in an incomplete user configuration with no privilege level.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Many candidates erroneously think that the order of class and authentication does not matter, but Junos requires class to be set first for the authentication to be applied correctly.

Treat this as a scenario question. Identify the problem, the constraint, and the best action. Then compare each option against those facts.
KKey Concepts to Remember

TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
user account configuration
Real-world example
How this comes up in practice
A junior network technician can log in to a core router but cannot reach the enable prompt or configuration mode. The AAA server is authenticating the login — but the authorisation policy only grants privilege level 1, not 15. Authentication (who you are) is working; authorisation (what you can do) is not.
