The correct answer identifies XML and JSON as the supported output formats for Cisco NX-API, with HTTP/HTTPS serving as the transport protocol. This is because NX-API is designed as a RESTful interface on Nexus switches, where all API calls are made over HTTP or HTTPS, and the switch can return structured data in either XML or JSON format to suit different automation and scripting needs. On the Cisco DCCOR 350-601 exam, this concept tests your understanding of programmatic device access and is often paired with a distractor that incorrectly lists CLI or SNMP as output formats. A common trap is assuming NX-API only supports JSON, but the exam explicitly validates that both XML and JSON are valid. Remember the memory tip: “NX-API speaks two languages—XML and JSON—over HTTP or HTTPS.”
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.

Correct answer & explanation
✓
NX-API uses HTTP/HTTPS as the transport protocol.
Cisco NX-API is a programmatic interface that uses HTTP/HTTPS as the transport protocol, allowing RESTful API calls to configure and monitor Nexus switches. It supports both XML and JSON output formats, enabling flexible data parsing in automation scripts. This makes options C and E correct.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Cisco often tests the misconception that NX-API uses SSH (like NETCONF) or is limited to specific hardware, when in fact it uses HTTP/HTTPS and is widely supported across Nexus platforms.
Detailed technical explanation
How to think about this question
NX-API exposes a RESTful API that accepts HTTP methods (GET, POST, PUT, DELETE) and returns responses in XML or JSON, as defined by the NX-API REST specification. Under the hood, it translates API calls into NX-OS CLI commands or direct configuration changes, making it ideal for integrating with tools like Ansible or Python scripts. A real-world scenario is automating VLAN provisioning across a fabric of Nexus 9000 switches using JSON payloads over HTTPS.

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 practitioner preparing for the 350-601 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
