The answer is that the two key benefits of using Cisco NX-API over traditional SSH-based scripting are its ability to return structured data in JSON or XML format and its support for batching multiple CLI commands into a single HTTP request. This is technically superior because structured data eliminates the need for screen-scraping and is version-independent, meaning your automation scripts won’t break when the CLI output format changes in a future NX-OS release. On the Cisco DCCOR / CCNP Data Center Core 350-601 exam, this question tests your understanding of how NX-API reduces round trips and improves reliability compared to SSH, which requires separate sessions for each command and returns unstructured text. A common trap is confusing NX-API’s batching with simple command concatenation—remember that NX-API sends commands as a single HTTP payload, not as sequential SSH keystrokes. Memory tip: think “JSON batch, no SSH scratch” to recall structured data and command batching as the two core advantages.
350-601 Automation Practice Question
This 350-601 practice question tests your understanding of automation. 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.
Which TWO are benefits of using the Cisco NX-API for network automation compared to traditional SSH-based scripting?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Enables batching multiple CLI commands in a single HTTP request
Option A is correct because the Cisco NX-API allows batching multiple CLI commands into a single HTTP request, which reduces the number of round trips and improves automation efficiency. This is a key advantage over traditional SSH-based scripting, where each command typically requires a separate connection or session.
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.
✓
Enables batching multiple CLI commands in a single HTTP request
Why this is correct
The NX-API supports the 'chunk' parameter to batch commands, reducing round-trips.
Related concept
Read the scenario before looking for a memorised answer.
✓
Returns structured data (JSON/XML) that is version-independent
Why this is correct
Structured output reduces parsing errors and is less affected by output formatting changes.
Related concept
Read the scenario before looking for a memorised answer.
✗
Supports direct configuration of IPSec and SSL VPNs
Why it's wrong here
NX-API can configure VPNs, but this is not a specific benefit over SSH; both can.
✗
Eliminates the need for any authentication
Why it's wrong here
Authentication (e.g., basic or token) is still required.
✗
Allows for real-time streaming of syslog messages
Why it's wrong here
NX-API does not stream syslog; that is done via other means.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Cisco often tests the distinction between NX-API's structured output and SSH's text-based output, and the trap here is that candidates may confuse NX-API's command batching with real-time streaming features like telemetry or syslog, which are separate technologies.
Detailed technical explanation
How to think about this question
NX-API uses a REST-like interface over HTTP/HTTPS, where requests can contain multiple commands in a JSON or XML array, and the response returns structured data (JSON/XML) that is version-independent, meaning the output schema remains consistent across NX-OS releases. This contrasts with SSH-based scripting, which often requires parsing unstructured text output that can change between versions, breaking scripts. In real-world automation, batching commands reduces latency and simplifies error handling by allowing atomic execution of related configuration steps.

Real-world example
How this comes up in practice
A small business has 20 workstations on the 192.168.1.0/24 network and one public IP from its ISP. The router uses PAT (NAT overload) so all 20 devices share one public address using different source ports. NAT questions test whether you understand the four address terms and which direction each translation applies.

Variation 1. Which tool provides a programmatic HTTP-based interface to execute CLI commands on Cisco Nexus switches and returns structured JSON data?
easy
A.Ansible
B.pyATS
C.Netmiko
✓ D.NX-API
Why D: NX-API (Option D) is the correct answer because it provides a programmatic HTTP/HTTPS-based interface that allows you to send CLI commands to Cisco Nexus switches and receive structured JSON (or XML) responses. This enables automation and integration without requiring an SSH session, directly fulfilling the question's requirement for an HTTP-based interface with structured JSON output.
