Core Knowledge Areas for 1H0_25
The 1H0_25 Horizon Administrator - 2025 exam is organized into six main sections that reflect the day-to-day responsibilities of an Omnissa Horizon administrator.

4. Troubleshooting
Troubleshooting is a major part of the exam and covers common problems involving connectivity, provisioning, RDS farms, authentication, desktop performance, network performance, user sessions, DEM, App Volumes, and Omnissa Access. Candidates should know how to use logs, consoles, diagnostic tools, and monitoring data to identify root causes and restore service.
5. Security and Compliance
This section focuses on protecting Horizon environments and managing secure user access. Candidates should understand how to configure session timeout policies, global security settings, authentication controls, and compliance-related settings through Horizon Console.
6. Automation and Integration

Best Study Tips for the 1H0_25 Exam
1. Understand the Horizon Architecture First
Before focusing on individual settings, understand how Connection Server, Horizon Agent, Horizon Client, vCenter, Active Directory, Unified Access Gateway, pools, and farms work together. A strong architecture foundation makes operational questions easier to solve.
2. Practice Horizon Console Administration
Spend time navigating Horizon Console and performing common tasks such as creating pools, configuring farms, assigning users, managing administrators, and reviewing environment status. The certification is administrator-focused, so hands-on familiarity is especially valuable.
3. Review Desktop Pools and RDS Farms Carefully
Desktop and application delivery are central to Horizon. Make sure you understand pool configuration, user assignment, instant-clone concepts, RDS farms, published applications, and session behavior.
4. Strengthen Identity and Access Knowledge
Review Active Directory integration, user entitlements, authentication, administrative roles, and delegated permissions. These areas appear frequently in real-world Horizon administration.
5. Learn Administrative Roles and Privileges
Understand how roles, privileges, and access groups control administrative access. Practice identifying which permissions are required for common administrative tasks.
6. Prepare for Different Question Formats
The 1H0_25 exam may include multiple-choice, multiple-selection, matching, drag-and-drop, point-and-click, hot-area, and build-list questions, so preparation should not be limited to standard single-answer questions.
7. Use Updated 1H0_25 Practice Tests
Use the latest Omnissa Horizon Administrator 1H0_25 OCA-H Practice Test from Passcert after reviewing each major topic. Practice results can help you identify weak areas and determine which Horizon technologies or administrative tasks need additional study.
