Who Should Take the 2H0_25 Exam?
The exam is intended for experienced administrators and engineers who deploy, operate, integrate, and troubleshoot Omnissa Horizon environments. Suitable roles include:
- Horizon administrators and engineers
- Virtual desktop infrastructure specialists
- End-user computing engineers
- Consultants responsible for Horizon deployments and upgrades
- Support engineers who diagnose complex VDI issues
Candidates should be comfortable working across Horizon rather than studying one component in isolation. The guide expects advanced administration, deployment to stated requirements, troubleshooting, and integration with Workspace ONE UEM.
2H0_25 Exam Objectives
Omnissa does not publish domain weights for this exam. The official guide lists seven numbered areas, even though one line in the guide refers to six sections.
| Domain | Main Focus |
| Infrastructure Planning and Management | Connection Servers, UAG, Active Directory, licensing, Edge Gateway, DEM, App Volumes, upgrades, recording, FIPS, GPU allocation, and resource planning. |
| Desktop, Application, and Profile Management | The official guide lists this heading but does not provide detailed task statements beneath it. |
| Monitoring and Optimization | Display protocols, golden-image tuning, login performance, pool capacity, and resource limits. |
| Troubleshooting | Connection failures, resource bottlenecks, storage I/O, GPU issues, storms, entitlements, drivers, and instant-clone debugging. |
| Security and Compliance | Certificates, MFA, two-factor authentication, clipboard controls, client-drive redirection, and USB policies. |
| Scale and Recovery | Component scaling, Cloud Pod Architecture, global entitlements, home sites, backup, recovery, and high availability. |
| Automation and Integration | Pool administration through APIs, Omnissa Access integration, Edge Gateway, DEEM agents, and Omnissa Intelligence. |
Skills and Technologies Covered
The largest body of published objectives sits under infrastructure planning and management. Candidates should understand component placement, high availability, certificates, load balancing, directory integration, licensing, upgrades, and capacity choices.
The remaining objectives test practical operations: improving display and login performance, diagnosing VDI failures, securing access and redirection, scaling a pod architecture, restoring services, and connecting Horizon with other Omnissa products.
2H0_25 Preparation Priorities
- Map the Horizon components and write down their dependencies before studying individual settings.
- Practice deployment and upgrade sequencing for Connection Server, UAG, App Volumes, DEM, and Horizon agents.
- Build a troubleshooting routine that separates connection, compute, storage, graphics, and entitlement problems.
- Review Cloud Pod Architecture, Global Entitlements, Home Sites, backup, and recovery tasks.
- Know where certificates, SAML, RADIUS, smart cards, redirection policies, and FIPS mode affect the design.
- Leave time to practice interactive question formats, especially matching and sequencing.
Common Preparation Mistakes
Studying Components Separately
A design can fail even when each component is configured correctly. Pay attention to dependencies among Connection Server, UAG, Active Directory, App Volumes, DEM, load balancers, and certificates.
Treating Every Slow Session as a Protocol Problem
Slow performance can come from login processing, storage I/O, CPU, memory, GPU profiles, pool capacity, or display settings. Check the evidence before changing protocol values.
Memorizing an Upgrade Order Without Reading the Scenario
Upgrade questions may change the answer by adding product dependencies, agent versions, backups, or required maintenance windows. Identify those constraints first.
Turning the Scaled Score Into a Percentage
The published threshold is 285 on a scaled system. It does not mean that candidates need 28.5 percent or any other direct percentage of correct answers.
Frequently Asked Questions
Is 2H0_25 mainly an administration exam?
It goes beyond routine administration. The blueprint expects candidates to plan deployments, manage dependencies, troubleshoot complex failures, secure access, scale services, recover components, and handle integrations.
Does the official guide publish domain weights?
No. It provides numbered objectives but does not assign percentages. The number of listed tasks should not be treated as an unofficial weighting system.
What is the best way to prepare for troubleshooting questions?
Practice starting with symptoms and available evidence. Separate access, entitlement, compute, storage, graphics, and configuration causes, then choose the next diagnostic step instead of jumping straight to a fix.
Are practice questions enough?
They are useful for checking coverage and improving timing, but they should support hands-on work and official documentation. Review why each wrong option fails, especially in design and troubleshooting scenarios.
