1Y0-204 Troubleshooting Practice Question
A Citrix Administrator is troubleshooting a published application that fails to launch for all users in the 'Sales' Delivery Group. The application is configured to run on a Server OS VDI. Users receive the error 'Cannot start app'. The administrator notices that the VDA machines in the Delivery Group are registered with the Delivery Controller, but the application's executable path is missing on the VDAs. Which action should the administrator take to resolve the issue?
⚠ Common exam trap
The trap here is assuming that a registration issue or broker service failure is the cause, when the error specifically points to a missing application executable on the VDA.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Verify the application's executable path in the Delivery Group configuration and ensure the application is installed on all VDAs.
The error 'Cannot start app' typically indicates that the application's executable cannot be found on the VDA. Since the VDAs are registered, the issue is not with the VDA registration or broker service. Verifying the executable path and ensuring the application is installed on all VDAs directly resolves the problem.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Restart the Citrix Broker Service on the Delivery Controller.
Why it's wrong here
Restarting the Citrix Broker Service is a troubleshooting step for broker-related issues, but the VDAs are registered and the error is specific to the application executable. This action would not install or correct the missing executable on the VDAs, and it would disrupt all users' sessions unnecessarily.
- ✗
Reinstall the VDA software on all machines in the Delivery Group.
Why it's wrong here
Reinstalling the VDA software is unnecessary because the machines are already registered with the Delivery Controller, indicating the VDA is functioning. The issue is specifically that the application's executable is missing, which is not resolved by a VDA reinstall. This action would not restore the missing executable and would cause unnecessary downtime.
- ✓
Verify the application's executable path in the Delivery Group configuration and ensure the application is installed on all VDAs.
Why this is correct
The error 'Cannot start app' often occurs when the application's executable is not present on the VDA. The administrator should check the published application's properties to confirm the correct path and ensure the application is installed on all VDAs in the Delivery Group. This directly addresses the missing executable issue.
- ✗
Recreate the Machine Catalog and add the VDAs again.
Why it's wrong here
Recreating the Machine Catalog is a drastic measure that does not address the root cause. Since the VDAs are registered and the issue is isolated to a missing application executable, recreating the catalog would not install the application. It would also require significant effort and disrupt the environment without resolving the problem.
