What is the Omnissa Horizon Administrator exam?
It is the exam that earns the Omnissa Certified Administrator - Horizon (OCA-H) credential: code 1H0_25, listed on Pearson VUE's public Omnissa exam list as "Horizon Administrator - 2025". Omnissa's own launch post says the credential validates core skills for deploying, managing, and troubleshooting virtual desktops and applications using Horizon, App Volumes, and Dynamic Environment Manager. It is the current administrator-level rung of Omnissa's end-user-computing ladder, introduced on a modern blueprint after the vendor retired the OCP exams on August 29, 2025. The sitting costs 250 USD, runs at a Pearson test center or online from home via OnVUE, and the credential it issues stays valid for two years from the date it posts.
What the OCA-H Actually Validates
Omnissa positions the OCA-H as proof of the day-one skills a Horizon administrator actually uses: deploying virtual desktops and applications, managing them through their lifecycle, and troubleshooting when users cannot connect or performance sags. The three product families named in the launch post - Horizon, App Volumes, and Dynamic Environment Manager - are the exam's center of gravity: brokering and pools on the Horizon side, application packaging and assignment on the App Volumes side, and user-environment personalization and policy on the DEM side.
The vendor's recommended-course mapping reinforces that reading. Omnissa points candidates at App Volumes and Dynamic Environment Manager training and the Horizon administration and operations course, then adds the honest caveat in its own FAQ: the recommended courses cover most topics but not all, and knowledge that can only be gained from hands-on experience is also needed to pass the exams. An administrator who has never built an instant-clone pool, attached an AppStack, or written a DEM condition set is studying descriptions of the exam, not the exam.
Because the credential launched on what Omnissa calls a modern blueprint reflecting current technologies and job roles, preparation material written for the retired OCP is not a safe proxy. The OCP exams stopped taking new registrations on August 29, 2025; the 2025-coded 1H0_25 is the live administrator exam now.
Codes, Fees, Validity, and Registration
The administrative facts are unusually clean for this program. The exam code is 1H0_25 and the listing name is "Horizon Administrator - 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.
At Home via OnVUE or at a Pearson Center
Both routes are live for this exam. Pearson's registration flow for 1H0_25 presents "In-person at a test center" and "Online with OnVUE" as the two delivery models, 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 OCA-H exam guide, and candidates are directed to that guide for exam details by every official channel, including the vendor's launch posts. 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 OCA-H exam guide before you schedule, and to treat any un-sourced number you find elsewhere as unverified.
Where OCA-H Sits in the Ladder
The OCA-H is the first rung of a four-level ladder that Omnissa rebuilt through 2025 and 2026: Administrator (OCA), Engineer (OCE), Design Engineer (OCDE), and Platform Engineer (OCPE). The engineer-level OCE-H launched on December 10, 2025, and Omnissa's eligibility rule for it is an OCA credential in the same track - so the OCA-H is the formal entry ticket to everything above it. The design-engineer exams are announced as coming later this year, and the platform-engineer cap goes to candidates who hold the design credential in both the Horizon and Workspace ONE tracks.
Omnissa's recommended profile for the OCE-H is IT professionals with five or more years of experience and at least 12 months managing Horizon environments - which tells you how the vendor expects the ladder to be climbed: administrator skills first, production depth second, then the advanced exam. Planning an OCA-H sitting inside that sequence is a career decision, not just an exam booking.
Get the OCA-H Sitting Handled
If the 1H0_25 sitting is the obstacle between you and the credential - the OnVUE room rules, the Clarus-to-Pearson flow, or simply the calendar - Exam Assist handles the sitting end to end: the exam-code 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 background, your delivery preference, and your deadline for an honest feasibility answer.
