What is the Omnissa Horizon Engineer exam?
It is the exam that earns the Omnissa Certified Engineer - Horizon (OCE-H) credential: code 2H0_25, listed on Pearson VUE's public Omnissa exam list as "Horizon Engineer - 2025". Omnissa's official launch post says the credential equips engineers with advanced skills to design, optimize, and secure enterprise-scale VDI environments - high availability, seamless user experience, and robust integration with Omnissa solutions. It launched on December 10, 2025 as the engineer-level rung of the rebuilt ladder, replacing the retired OCAP track. The sitting costs 250 USD, requires the OCA-H first, runs at a Pearson test center or online from home via OnVUE, and issues a credential valid for two years.
What the OCE-H Actually Validates
The level jump is the point. The OCA-H proves administrator craft - deploying, managing, and troubleshooting virtual desktops and applications with Horizon, App Volumes, and Dynamic Environment Manager. The OCE-H proves engineering judgment on top of it: designing for high availability, optimizing the user experience at enterprise scale, securing the environment, and integrating Horizon with Omnissa Access and Omnissa Intelligence. The launch post frames the outcome plainly - OCE empowers you to configure resilient environments, automate workflows, and integrate cutting-edge solutions.
The vendor's own audience math tells you who the exam is written for. Omnissa addresses the Horizon track to IT professionals with five or more years of experience and twelve months managing Horizon environments, and it maps two recommended courses - Horizon 8: Deploy and Manage, and Horizon Troubleshooting - before adding the standing caveat that courses cover most topics but not all, and knowledge that can only be gained from hands-on experience is also needed to pass. Training is recommended, not required; the blueprint is the gate.
Omnissa's exam-day FAQ adds a hands-on signal worth heeding: candidates who hit a technical issue with the live lab during the exam are told to report it to the proctor immediately and ask for a Pearson VUE VSS support ticket, because issues reported after the exam cannot be validated. Read that as the vendor telling you the sitting involves doing, not just describing.
The Prerequisite: OCA-H First
The engineer level is the only rung of the live ladder with a formal entry requirement, and Omnissa states it in one line: all you need to apply for the Omnissa Certified Engineer certification is an Omnissa Certified Administrator credential in the respective track. For the 2H0_25 sitting, that means the OCA-H earned through exam 1H0_25. Registration runs through the Clarus portal, which checks the prerequisite against your credential record before the attempt exists.
The practical sequence for a candidate starting cold is two sittings, not one: the 1H0_25 administrator exam first, the 2H0_25 engineer exam second, each 250 USD. Unexpired legacy credentials from the VMware era are honored as prerequisites for higher-level certifications under the retirement rules, so a candidate holding a current legacy credential should check its standing in Clarus before assuming the OCA sitting is required.
There are no training prerequisites anywhere in the program - Omnissa removed mandatory training on August 29, 2025 - so nothing administratively blocks a qualified candidate's booking except the OCA gate itself. And language is not a barrier either: Omnissa's certification team confirms the OCE exams run in Japanese as well as English, with identical rules, passing scores, and proctoring standards.
Codes, Fees, Validity, and Registration
The administrative facts are unusually clean for this program. The exam code is 2H0_25 and the listing name is "Horizon Engineer - 2025" on Pearson VUE's public Omnissa exam list. The fee is 250 USD - Omnissa's official FAQ states that every certification exam in the program costs the same flat amount, paid in the Pearson VUE booking flow by card or by applying a voucher code on the payment and billing page. And the credential is valid for two years from the issue date, like every other Omnissa credential.
Registration is a two-account flow. You start in Omnissa's Clarus portal to register the credential attempt and manage your records, then schedule the sitting itself through Pearson VUE. After the exam, the certificate and digital badge are issued into the same Clarus My Credentials dashboard, which is also where you download the certificate PDF and push the badge to a profile. Candidates with certification history from the VMware era find those legacy records in CertMetrics and Credly, not in Clarus.
Retake and reschedule specifics live in the Omnissa Testing Policies document linked from Pearson's program page - confirm them there when you book rather than trusting any summary, including this one.
At Home via OnVUE or at a Pearson Center
Both routes are live for this exam, verified at the strongest tier available to the public. Pearson's registration flow for 2H0_25 presents "In-person at a test center" and "Online with OnVUE" as the two delivery models - checked on the delivery-models step for this exact exam code in a real browser on 2026-10-05 - and Omnissa's own certification journey says the same thing in the vendor's words: take your exam online or at a testing center with Pearson's proctoring options. Nothing on Pearson's Omnissa pages restricts at-home delivery by country.
The at-home route comes with a published environment bar: Windows 10 or macOS 14 or higher; a working webcam, microphone, and speaker with no headphones or headsets; one display only - multi-monitor setups are not permitted; at least 6 Mbps down and 2 Mbps up; and every application except OnVUE closed. Pearson warns that failing these minimums on exam day can cancel the sitting and forfeit the fee, and it offers a system test to run in advance on the exact machine. Identification at check-in must come from the accepted list: international passport, plastic driver's license, national, state, provincial, or EU ID card, alien registration card, or an approved Aadhaar card.
What Omnissa Publishes About the Format - and What It Does Not
Here is the part most prep sites get wrong. Omnissa publishes the blueprint-level facts - question count, sitting length, passing score, and objective weights - inside the official OCE-H exam guide, and its launch post tells candidates to download that guide from the Omnissa Certification page for the detailed blueprint, recommended resources, and key focus areas. Those numbers are not republished on any official marketing or registration page we can verify today. This guide deliberately does not quote them.
That discipline matters because third-party dump and prep sites fill the vacuum with invented figures - fixed question counts, exact pass marks, even "exam durations" presented without a source. None of those numbers trace to Omnissa. If your planning depends on the precise item count or time limit, the only compliant move is to read the official OCE-H exam guide before you schedule, and to treat any un-sourced number you find elsewhere as unverified.
The Retired OCAP Track and What Replaced It
The OCE did not appear in a vacuum. Omnissa retired the OCP exams on August 29, 2025, kept the OCAP exams available until November 2025, and then replaced the OCAP and Specialist tracks with the OCE on December 10, 2025. Legacy credentials remain valid until they expire, and unexpired ones are honored as prerequisites for higher-level certifications - the retirement kills the exams, not the credentials already earned.
Candidates caught mid-transition get a clean choice in Omnissa's own FAQ: if you hold a scheduled OCAP or Specialist exam with Pearson VUE, you can proceed with it, or cancel for a full refund and register for the OCE instead. Pearson's public exam list still displays the legacy-era codes 3V0-61.24, 5V0-61.22, and 5V0-62.22 alongside the 2025 family - their bookable status for new attempts is a Clarus question, not a website question. For anyone starting today, the live engineer exam is the 2025-coded 2H0_25.
Get the OCE-H Sitting Handled
If the 2H0_25 sitting is the obstacle between you and the engineer credential - the OCA sequencing, the OnVUE room rules, the Clarus-to-Pearson flow, or simply the calendar - Exam Assist handles the sitting end to end: the exam-code and prerequisite confirmation, the delivery-route compliance check, the scheduling coordination, and the proctored sitting itself. The service fee is due only after the agreed result posts and you have verified it in your Clarus dashboard. Send your OCA-H status, your delivery preference, and your deadline for an honest feasibility answer.
