- A
Guest Shell
Why wrong: Guest Shell provides a bash environment, not REST API.
- B
NX-API REST
NX-API REST uses XML/JSON over HTTP/HTTPS for configuration.
- C
NETCONF
Why wrong: NETCONF uses XML over SSH, not HTTP/HTTPS.
- D
NX-API CLI
Why wrong: NX-API CLI sends CLI commands, not REST.

350-601 Automation Practice Question
This 350-601 practice question tests your understanding of automation. 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. 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.
A network engineer wants to automate the configuration of VLANs on a Nexus 9000 switch using REST-based APIs. Which approach should be used to send NX-OS commands via HTTP/HTTPS in JSON format?

Correct answer & explanation
✓
NX-API REST
NX-API REST supports XML or JSON over HTTP/HTTPS and allows configuration via RESTful operations. NX-API CLI sends CLI commands over HTTP, not REST. Guest Shell runs bash scripts. NETCONF uses XML over SSH.
Key principle: A trunk being up does not mean the VLAN is allowed across it. Always verify the allowed VLAN list and whether the VLAN exists on both switches.

Common exam traps
Common exam trap: an active trunk can still block the VLAN you need
A trunk being up does not prove every VLAN is crossing it. Check allowed VLAN lists, native VLAN mismatch, VLAN existence and access-port assignment.
Trap categories for this question
Command / output trap
NX-API CLI sends CLI commands, not REST.
Detailed technical explanation
How to think about this question
VLAN questions usually combine access-port and trunking clues. The key is to identify whether the issue is local to one switchport, caused by the trunk, or caused by the VLAN not existing where it needs to exist.
KKey Concepts to Remember
- Access ports place end devices into a single VLAN.
- Trunk ports carry multiple VLANs between switches.
- Allowed VLAN lists decide which VLANs can cross a trunk.
- Native VLAN mismatch can create confusing symptoms.
TExam Day Tips
- Use show vlan brief to verify access VLANs.
- Use show interfaces trunk to verify trunk state and allowed VLANs.
- Do not treat every same-VLAN issue as a routing problem.
Key takeaway
A trunk being up does not mean the VLAN is allowed across it. Always verify the allowed VLAN list and whether the VLAN exists on both switches.
Real-world example
How this comes up in practice
A help-desk technician troubleshoots why a newly connected PC cannot reach shared printers on the same floor. The cable is good, the switch port is active, but the PC is in VLAN 20 and the printers are in VLAN 10. The uplink trunk only allows VLAN 10. A trunk being up does not mean every VLAN crosses it.
