A Python script is automating a series of API calls to a network device. The script must handle rate limiting by the API, which returns a 429 Too Many Requests status. Which strategy should the engineer implement?

Ignore the 429 and continue sending requests

Implement retry logic with exponential backoff and respect the Retry-After header

Switch to a different HTTP method to avoid the rate limit

A Python script is using a session object from the requests library to interact with a network device API that uses cookie-based authentication. The engineer notices that the session is not maintaining the authentication cookie across requests. What is the most likely cause?

The Authorization header is overriding the cookie

The session object is not being reused; a new session is created for each request

The Content-Type header is set incorrectly

The API does not support cookies

A Python script using the requests library sends a GET request to a network device's REST API to retrieve interface statistics. The script receives a response with status code 404. What is the most likely cause?

The API endpoint URI is incorrect or the resource does not exist

The client is not authenticated

The server encountered an internal error

A network engineer is designing a Python script to interact with a REST API that follows the HATEOAS principle. The API returns links in responses to guide the client. Which approach should the engineer take to ensure the script remains robust when the API evolves?

Hardcode the URIs for all resources

Use a different HTTP method for each resource

Follow the links provided in the API responses to navigate resources

Use only the base URI and assume the resource structure
