Cisco Certified DevNet Associate Intermediate Practice Exam: Medium Difficulty 2025

A developer is writing a Python script that consumes a REST API returning a list of device objects as JSON. The script must transform the data into a simplified list of dictionaries and handle missing keys without crashing. Which approach best balances readability and resilience?

You are troubleshooting an API integration where a POST request to create a resource is returning HTTP 415. The endpoint is documented to accept JSON. Which client-side change is the most likely fix?

A script polls a network controller API every 5 seconds for device health. During an incident, the API begins responding with HTTP 429. The operations team still needs near-real-time data but must be a good API consumer. What is the best client behavior?

A developer uses a REST API that supports pagination. They must retrieve all items efficiently without missing or duplicating results when new items are created during the collection process. Which strategy is most appropriate?

You are building an internal tool that uses Cisco platform APIs to push configuration changes. Security requires least privilege and short-lived access without embedding user passwords in scripts. Which approach best meets these requirements?

A team needs a lightweight integration that subscribes to network events (such as interface up/down) from a Cisco platform and triggers an automation workflow. They want to avoid constant polling. Which design is most appropriate?

You are containerizing a Python API client that will run as a scheduled job in a CI/CD pipeline. The job needs a secret API token and must avoid leaking it in logs or container layers. Which practice is best?

A script uses SSH to configure 200 switches. It works manually but intermittently fails in automation due to timing and prompt differences across device models. You want a more reliable and idempotent approach. What is the best next step?

An automation job must update access lists across multiple devices. If any device fails mid-run, the team needs a predictable outcome and easy recovery. Which pattern best supports this requirement?

A developer is building an app that must reach a device management API on a different subnet. Connectivity works from the developer laptop but fails from a container running in a Kubernetes cluster. The API uses HTTPS on TCP/443. Which set of checks is most relevant to isolate the issue?
