350-401 Practice Question: An engineer is using a Python script to retrieve…
An engineer is using a Python script to retrieve interface statistics from a Cisco IOS-XE device via the REST API. The script sends a GET request to 'https://device/restconf/data/ietf-interfaces:interfaces/interface=GigabitEthernet1/statistics' and receives a 404 Not Found response. The interface exists and is operational. What is the most likely issue?
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
✓
The URI is incorrect; statistics are under 'interfaces-state' not 'interfaces'.
The 404 error indicates the resource was not found. In RESTCONF, the URI must use the correct encoding for interface names, especially if they contain special characters like a slash. The interface name 'GigabitEthernet1' should be URL-encoded as 'GigabitEthernet1' (no encoding needed here), but the issue is that the URI path must match the YANG module structure exactly. The statistics data is often under a separate container like 'interfaces-state' in the ietf-interfaces model, not directly under 'interface'. The correct URI for operational statistics is typically 'ietf-interfaces:interfaces-state/interface=GigabitEthernet1/statistics'.
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 interface name must be URL-encoded because it contains a slash.
Why it's wrong here
Incorrect because 'GigabitEthernet1' does not contain a slash; URL encoding is not the issue here.
- ✓
The URI is incorrect; statistics are under 'interfaces-state' not 'interfaces'.
Why this is correct
Correct because operational state data like statistics is in the 'interfaces-state' container, while 'interfaces' contains configuration data.
- ✗
The device requires authentication; the script must include a valid token.
Why it's wrong here
Incorrect because a 404 error indicates resource not found, not authentication failure (which would be 401).
- ✗
The REST API is not enabled on the device; the engineer must enable it first.
Why it's wrong here
Incorrect because if the API were not enabled, the response would likely be a connection error or 403, not 404.
