No. This is independent study material produced by an independent study platform. We are not affiliated with, endorsed by, or sponsored by Juniper Networks or Hewlett Packard Enterprise. Always confirm certification details on the vendor's own certification site before you register, pay, or schedule an exam appointment.

We cannot state this. The official certification page returned an HTTP 404 error when retrieved on 2026-11-06, so no question count, time limit, or format information could be verified. Any number you see elsewhere may be outdated. Check the vendor's current certification page or your testing account before scheduling.

Unknown from our permitted source. The certification page was unavailable, so the passing score, exam fee, and any regional pricing differences are unverified and shown as null on this page. Confirm both directly with the certification provider, since fees and cut scores change between exam revisions.

Associate-level DevOps content assumes comfort with Junos configuration plus basic scripting. Candidates who only know CLI often struggle with data formats (JSON, YAML), reading API responses, and version-control workflow rather than with Junos itself. Expect to practise Python and templating in a lab, not just read about them, before attempting the exam.

Start with DevOps culture and version control, because everything else depends on committing and reviewing changes. Then learn data formats and scripting, move to configuration templating and infrastructure as code, and finish with APIs and CI/CD pipelines that push validated configuration to Junos devices. Practise each stage in a lab rather than studying topics in isolation.

Candidates typically lose marks on YAML indentation, confusing JSON objects with arrays, misreading a REST or RPC response, and describing a pipeline they have never built. Another frequent problem is memorising syntax without understanding idempotency. Build one small automated workflow end to end and be able to explain each step before exam day.

We cannot confirm the retake policy. The official page was not reachable on 2026-11-06, so waiting periods, attempt limits, and any retake fees are unverified. Check the certification provider's policy page or your candidate agreement, which states the binding rules for your account at the time you sit the exam.

Unverified. The validity period could not be sourced because the certification page returned a 404 error. Recertification rules also change, sometimes tied to continuing education or a newer exam version. Confirm the current validity and recertification options with the certification provider before you plan your study timeline.

Yes, practical Junos knowledge is assumed. Automation content makes little sense without understanding hierarchy, commit and rollback, candidate configuration, and how a device exposes its state. You do not need expert routing depth, but you should be able to configure, commit, verify, and roll back confidently on a lab device.

A lab is strongly recommended. Automation topics such as templating, API calls, and pipelines are procedural skills that reading alone rarely cements. A virtual Junos device plus Git and a scripting environment is enough to practise committing changes, parsing responses, and validating configuration before deployment.
