1Y0-312 Advanced Provisioning and Image Management Practice Question
An administrator is using Machine Creation Services (MCS) to provision a new catalog of 200 non-persistent Windows 10 desktops from a master image. The master image was created on a host with a different CPU generation than the target hosts. Users report that after provisioning, the desktops fail to boot with a STOP error 0x0000005A. Which action should the administrator take to resolve this issue?
⚠ Common exam trap
The trap here is assuming that the error is related to storage or graphics when it is actually a CPU instruction set mismatch.
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
✓
Recreate the master image on a host with the same CPU generation as the target hosts.
The 0x0000005A STOP error indicates an unsupported processor. When using MCS, the master image must be created on a host with the same CPU generation as the target hosts to ensure compatibility. Recreating the master image on a compatible host resolves the issue, while other options do not address the CPU mismatch.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Modify the catalog to use a different storage repository with higher IOPS.
Why it's wrong here
Storage performance does not cause a STOP 0x0000005A error. This error is specifically related to CPU compatibility. Changing the storage repository would not resolve the boot failure and would waste time and resources without addressing the root cause.
- ✗
Run the 'Update Machines' wizard to push a new image to the existing desktops.
Why it's wrong here
Updating machines would not fix the CPU mismatch because the same incompatible master image would be used. The error occurs at boot time due to processor differences, so updating with the same image will not help. The master image must be recreated on compatible hardware.
- ✗
Enable the 'Use machine creation services (MCS) with a hardware-accelerated graphics' option in the catalog.
Why it's wrong here
This option is for GPU acceleration and does not address CPU instruction set mismatch. The STOP error 0x0000005A indicates a driver or hardware abstraction layer issue, not graphics. Enabling hardware acceleration would not resolve the boot failure and could introduce additional complexity.
- ✓
Recreate the master image on a host with the same CPU generation as the target hosts.
Why this is correct
The STOP error 0x0000005A (UNSUPPORTED_PROCESSOR) occurs when the image was prepared on a CPU with a different instruction set. Recreating the master image on a host with the same CPU generation ensures compatibility and allows the desktops to boot successfully.
