350-601 Automation Practice Question
Which THREE components are required to successfully use NETCONF for configuration automation on a Nexus 9000 switch?
⚠ Common exam trap
Cisco often tests the misconception that NX-API is a prerequisite or fallback for NETCONF, but in reality they are independent automation interfaces with different transport and data encoding methods.
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
✓
SSH connectivity must be established to the switch
B is correct because NETCONF operates over SSH as its transport protocol (RFC 6242), so SSH connectivity to the switch is mandatory for establishing the NETCONF session. Without SSH, the NETCONF client cannot connect to the NETCONF server running on the Nexus 9000.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The NX-API must be enabled as a fallback
Why it's wrong here
NETCONF operates independently; NX-API is not required.
- ✓
SSH connectivity must be established to the switch
Why this is correct
NETCONF uses SSH as its transport protocol (RFC 6242).
- ✓
The NETCONF agent must be enabled via 'feature netconf' configuration
Why this is correct
Without the feature, the NETCONF server will not listen for connections.
- ✓
YANG models must be installed or supported for the target configurations
Why this is correct
NETCONF uses YANG as its data modeling language; the switch must support the models needed.
- ✗
The switch must be running the NX-OS Essentials license
Why it's wrong here
NETCONF is available on all NX-OS versions without additional licensing.
