A script uses an API key in the query string to authenticate to a network device API. The company security policy requires all API traffic to be encrypted. What is the most important constraint to address?

Use a different HTTP method to hide the key

Use HTTPS instead of HTTP to encrypt the API key in transit

Use a longer API key to prevent brute force

An application retrieves a list of 10,000 network devices from a Cisco DNA Center API. The API returns 500 devices per page. The developer notices that the application only processes the first page. What is the most likely reason?

The application is not following the pagination links or incrementing the page number

The API does not support pagination for this endpoint

The API returns all 10,000 devices in one response but the application truncates it

The network latency is too high to fetch additional pages

An API client has a valid API key but receives a 403 Forbidden response when trying to access a specific endpoint. What is the most likely reason?

The API key is invalid or expired.

The client is authenticated but lacks the necessary authorization to access that endpoint.

The API server is experiencing a network outage.

The client is sending too many requests and is being rate limited.

Why is it important for an API client to implement a retry policy with exponential backoff?

To convert error responses into successful responses.

To avoid overwhelming the API server with immediate retries after transient errors.

To bypass authentication requirements for subsequent requests.

To ensure that all requests are retried exactly three times.

What is the primary purpose of API throttling?

To control the rate at which requests are processed to protect the API server from overload

To transform data from one format to another, such as XML to JSON

To encrypt data transmitted between the client and the API server

To authenticate users before they can access the API
