200-901 Cisco Platforms and Development Practice Question
This 200-901 practice question tests your understanding of cisco platforms and development. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. 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.
Exhibit
Router# show running-config | include username
username admin privilege 15 secret 5 $1$abc$xyz
username devuser privilege 1 secret 5 $1$def$123
Refer to the exhibit. A developer needs to authenticate to this router via NETCONF using the devuser credentials. Why might authentication fail?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The devuser has privilege level 1, which is not enough for NETCONF access
NETCONF access requires a minimum privilege level of 15 on Cisco IOS/IOS-XE devices. The devuser has privilege level 1, which restricts the user to basic monitoring commands and prevents NETCONF operations. Even with correct SSH and authentication, the privilege level mismatch causes the NETCONF session to be rejected.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
NETCONF requires AAA authentication
Why it's wrong here
NETCONF can use local accounts.
✓
The devuser has privilege level 1, which is not enough for NETCONF access
Why this is correct
Privilege level 1 is too low for NETCONF.

Common exam trap: answer the scenario, not the keyword
Cisco often tests the misconception that any valid SSH user can use NETCONF, but the trap is that NETCONF requires privilege level 15 regardless of SSH access or authentication method.
Detailed technical explanation
How to think about this question
NETCONF over SSH (RFC 6242) relies on the underlying SSH session for transport, but the NETCONF subsystem enforces its own authorization checks. On Cisco devices, the 'netconf-yang' feature requires privilege level 15 for all NETCONF operations, including 'get' and 'edit-config'. This is because NETCONF effectively provides full device configuration access, and Cisco restricts it to the highest privilege level to prevent unauthorized changes.

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
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
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.
