1Y0-312 Advanced Provisioning and Image Management Practice Question
Exhibit
Provisioning_Server_Log: [ERROR] 2023-10-12 14:20:05: Failed to connect to vDisk store: \\FileServer01\Store\Windows10_Gold.vhdx. Access Denied. Check permissions for the Citrix Provisioning Computer Account.
Refer to the exhibit. An administrator is troubleshooting a vDisk access error in the Provisioning console. The Provisioning Server is unable to access the vDisk store on the file server. What is the most likely cause of this error?
⚠ Common exam trap
Candidates often assume the issue lies with Active Directory domain membership or local firewall rules rather than checking direct file share access permissions for the server account.
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
✓
The Provisioning Server's computer account lacks necessary permissions on the file share.
The error 'Access Denied' clearly points to a permission mismatch between the Provisioning Server's computer account and the file share. In Citrix Provisioning, the service account or the computer account of the Provisioning Server must have 'Full Control' or at least 'Read/Write' access to the underlying storage share. This is critical for the server to stream vDisks and manage lock files during the target device boot sequence.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
The Provisioning Server's computer account lacks necessary permissions on the file share.
Why this is correct
The Provisioning Server uses its computer account (or a configured service account) to access the vDisk store. If the NTFS or share permissions do not grant this account appropriate rights, the server cannot access the .vhdx files, resulting in the reported Access Denied error during the streaming process.
- ✗
The vDisk is currently locked by another Provisioning Server in the farm.
Why it's wrong here
While vDisk locking occurs, the specific error returned would indicate a file lock conflict rather than an 'Access Denied' permission issue. If a lock conflict occurred, the log would explicitly mention that the file is in use by another process or server, not that access is denied.
- ✗
The target device is attempting to mount a vDisk that has not been assigned.
Why it's wrong here
If a vDisk were not assigned, the error would manifest during the target device handshake, stating that no vDisk was found for the device's MAC address. The error shown occurs at the server level, indicating the server itself cannot read the file from the designated storage location.
- ✗
The Provisioning Server has reached the maximum number of concurrent vDisk connections.
Why it's wrong here
Reaching a maximum connection threshold would result in a performance degradation or a specific 'connection limit reached' error message, not an 'Access Denied' message. The system is failing at the file system access layer, which suggests a security or permission misconfiguration rather than a performance or capacity constraint.
