1Y0-204 Troubleshooting Practice Question
A Citrix Administrator is troubleshooting an issue where a published application fails to launch for all users. The administrator has verified that the VDA is registered and the application is installed on the VDA. Which TWO actions should the administrator perform to identify the cause? (Choose two.)
⚠ Common exam trap
The trap here is focusing on client-side or StoreFront components when the failure affects all users, indicating a server-side or brokering issue.

Correct answer & explanation
✓
Review the Delivery Controller's Citrix Broker Service logs.
When a published application fails to launch for all users, the issue is likely on the VDA or in the brokering process. Checking the Windows Event Log on the VDA can reveal application-specific errors, while the Delivery Controller's Citrix Broker Service logs can show brokering failures. These two sources provide complementary information to pinpoint the cause. Other actions like restarting StoreFront or reinstalling Workspace app are either disruptive or irrelevant to a systemic failure.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Use Citrix Director to view the application's historical launch data.
Why it's wrong here
Citrix Director provides monitoring and historical data on sessions and applications, but it may not provide detailed error information for a specific application launch failure. While Director can show failure trends, it often lacks the granular error details found in event logs. For a complete picture, logs from the VDA and Delivery Controller are more direct and informative.
- ✓
Review the Delivery Controller's Citrix Broker Service logs.
Why this is correct
The Citrix Broker Service logs on the Delivery Controller record brokering activities, including application launch requests and failures. If the application fails to launch for all users, the broker may have logged an error during the launch process, such as a failure to contact the VDA or an invalid application configuration. These logs help isolate whether the issue is in brokering or on the VDA.
- ✓
Check the Windows Event Log on the VDA for application errors.
Why this is correct
The Windows Event Log on the VDA records application-specific errors, such as missing DLLs, permission issues, or crashes. When an application fails to launch for all users, the VDA is the common point of failure. Reviewing the Application log can reveal the exact error, such as a side-by-side configuration error or a .NET exception, guiding further troubleshooting.
- ✗
Restart the StoreFront server.
Why it's wrong here
Restarting StoreFront would affect all users and is not a diagnostic step. StoreFront is responsible for authentication and enumeration, but if the application fails to launch after enumeration, the issue is likely not StoreFront. Restarting would not provide any diagnostic information and could disrupt other users. It is an unnecessary and disruptive action.
- ✗
Reinstall the Citrix Workspace app on a user's device.
Why it's wrong here
Reinstalling Workspace app on one user's device would not address a failure affecting all users. The issue is systemic, likely on the VDA or Delivery Controller. Workspace app reinstallation is a client-side fix and would not resolve a server-side problem. It is a time-consuming step that does not yield diagnostic data for this scenario.
