Free Practice Questions for Cisco 350-401 Exam

The correct answer is A. The script retrieves device information by sending HTTP requests to the device ' s API endpoints.

The script uses the Python requests library:

response = requests . get( url )

This sends an HTTP GET request to:

http:// < device_ip > /api/device/info

This indicates communication with a REST API endpoint exposed by the network device.

Builds a URL using the device IP

Sends an HTTP GET request to the API

Checks if the response status code is 200 (OK)

If successful:

return response . json()

→ Converts the API response into a Python dictionary

Prints the retrieved device information

The script is clearly performing a read operation (GET)

It interacts with a REST API

It retrieves device information, not configuring anything

B. Configures device settings via secure connection ❌ No POST/PUT/PATCH methods are used ❌ No HTTPS or authentication shown

C. Establishes SSH connection ❌ No SSH libraries (like Paramiko or Netmiko) are used

D. Parses JSON into tabular structure ❌ It only returns and prints JSON ❌ No formatting (like pandas/table conversion) is performed

requests.get() → Retrieve data (READ)

requests.post() / put() → Modify or create data

.json() → Converts API response into Python dictionary

Key takeaway:

REST API + GET request = data retrieval from device
