As of March 11, 2026, Cisco's live public path for exam 200-901 is branded CCNA Automation, while the older DevNet Associate name remains common in study materials and job postings. Cisco publishes a 120-minute limit, a $300 fee, six weighted domains, and pass/fail scoring with results available online within 48 hours, but it does not publish a fixed passing score or a fixed public question count. The heaviest domains are Understanding and Using APIs and Infrastructure and Automation at 20% each, with the other four domains weighted at 15% each.

Sample DevNet Associate Practice Questions

Try these sample questions to test your DevNet Associate exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 200+ question experience with AI tutoring.

1A team building an internal network automation tool wants faster feedback and fewer large releases. Which development approach best supports that goal?

A.Short iterative development cycles with regular stakeholder review

B.A single waterfall release after all features are completed

C.Manual script changes made directly on production devices

D.Delaying testing until the project reaches feature complete

Explanation: Iterative delivery lets the team ship small, testable increments and adjust based on feedback. That lowers release risk compared with waiting for one large cutover at the end.

2A Python script parses a REST API response and needs to access values by field name such as `response['hostname']`. Which data type should the parsed JSON object become?

A.List

B.Dictionary

C.Set

D.Tuple

Explanation: A JSON object maps naturally to a Python dictionary because it stores key-value pairs. That allows direct access by field name and is the standard structure returned by JSON parsers.

3Why are YANG models useful in network automation workflows?

A.A YANG model defines structured data, types, and constraints for configuration and state

B.A YANG model encrypts API traffic between clients and devices

C.A YANG model replaces the need for HTTP status codes

D.A YANG model converts every API into a command-line interface

Explanation: YANG gives automation tools a predictable schema for network data instead of ambiguous free-form text. That makes validation, serialization, and API interactions more reliable.

4A refactor changes a function that builds a RESTCONF payload for interface configuration. Which test best catches an incorrect JSON structure before deployment?

A.Manual SSH login to one switch after release

B.A unit test that compares the function output against an expected payload

C.A load test that measures CPU usage on the API server

D.A topology diagram review by the network team

Explanation: A focused unit test validates the payload builder against known inputs and expected JSON output. That catches regressions early without needing a live device or full integration environment.

5A developer needs to fix a bug in an automation script without destabilizing the code that other engineers are using. What is the best workflow?

A.Edit the main branch directly and force-push the change

B.Create a feature branch, commit the fix, and merge it through a pull request

C.Wait until several unrelated changes are ready and commit them all together

D.Copy the repository to a shared folder and email the updated file

Explanation: A feature branch isolates the change so it can be reviewed, tested, and merged cleanly. Pull requests also provide traceability and reduce the chance of breaking shared code unexpectedly.

6An operations team wants a human-friendly file format for editing small inventories and variables used by automation tools. Which format is most commonly chosen for that purpose?

A.JSON

B.YAML

C.PCAP

D.JPEG

Explanation: YAML is widely used for inventories and variable files because it is concise and easier for humans to read than many other formats. Tools such as Ansible commonly use YAML for exactly that reason.

7A Python helper is defined as `def collect_device(host, results=[]):`. After several calls, old hosts keep appearing in new results. What change fixes the bug?

A.Change the default to `None` and create a new list inside the function

B.Replace the list with a global variable so every call shares the same state

C.Convert the function into a generator and keep the same default list

D.Sort the list before returning it

Explanation: Default mutable arguments are created once, so the same list is reused across calls. Using `None` and initializing inside the function ensures each call gets a fresh list unless one is explicitly passed in.

8Your team wants every pull request for automation code to fail immediately if linting or unit tests break. Where should that enforcement happen?

A.In a CI job triggered by commits and pull requests

B.In the production deployment stage after the merge

C.In a monthly architecture meeting

D.In a device banner that reminds engineers to test manually

Explanation: CI gives the team a consistent gate that runs automatically for every change. Catching failures before merge is faster and safer than discovering them after deployment has started.

9A client application needs to retrieve the current list of devices from a REST API without changing anything. Which HTTP method should it use?

A.POST

B.GET

C.PUT

D.DELETE

Explanation: GET is the standard HTTP method for reading a resource representation. It is intended for retrieval rather than creation, replacement, or deletion.

10An API consumer needs to change only the `description` field of an existing resource. Which HTTP method is the best fit?

A.PATCH

B.GET

C.HEAD

D.TRACE

Explanation: PATCH is designed for partial modification of an existing resource. It is a better fit than methods intended for retrieval or diagnostics when only one field needs to change.

DevNet Associate Study Tips from Top Performers

1Treat Python control flow, JSON and YAML structure, HTTP methods, and status codes as baseline fluency items. If those basics are slow, scenario questions become much harder.

2Practice real API calls with headers, query parameters, authentication tokens, and parsed responses. DevNet questions are easier when you can visualize actual request and response behavior.

3Weight your study time toward the two 20% domains: APIs and Infrastructure and Automation. Those areas drive the largest share of blueprint coverage.

4Use hands-on labs for RESTCONF, Ansible, Docker, and Cisco platform APIs so you learn common failure modes instead of memorizing only happy-path definitions.

5Know the February 3, 2026 rebrand as context, but do not overstudy the naming change. Cisco's blueprint still rewards practical automation and programmability judgment more than branding trivia.

Frequently Asked Questions

Is DevNet Associate still an active Cisco certification name in 2026?

Cisco's current public branding changed on February 3, 2026, when the active 200-901 path moved under CCNA Automation. Older study materials, resumes, and job postings still commonly refer to the same certification path as DevNet Associate, so both names still appear in the market.

How many questions are on the DevNet Associate exam?

Cisco's current public 200-901 CCNAAUTO exam page does not publish a fixed question count. Cisco does publish the 120-minute time limit, pass/fail scoring, and the weighted domain breakdown, so candidates should prepare for a standard associate-level written exam rather than rely on a guaranteed public question total.

What is the passing score for DevNet Associate?

Cisco does not publish a fixed numeric passing score for the 200-901 exam. The exam is graded pass or fail, and Cisco states that results are available online within 48 hours.

Which domains matter most for DevNet Associate prep?

The two largest official domains are Understanding and Using APIs and Infrastructure and Automation, each weighted at 20%. The other four domains are still meaningful at 15% each, so the exam rewards balanced preparation instead of a narrow single-domain strategy.

What topics should I prioritize first?

Start with Python basics, JSON and YAML, HTTP methods, status codes, and API authentication because those ideas support several domains at once. Then spend extra time on RESTCONF and NETCONF concepts, YANG, Ansible, Cisco platform APIs, and secure deployment workflows because those areas combine higher exam weight with practical scenario depth.

Can I take the Cisco 200-901 exam online, and what is the retake policy?

Cisco written exams are delivered through Pearson VUE, and Cisco maintains an online-proctored testing program where available. If you fail a Cisco written exam, Cisco's published policy requires a 5-calendar-day wait before retaking the same exam, and the full exam fee applies again.
