The correct answer is C. The backplane of the enclosure is faulty. When all blades in an enclosure fail simultaneously after migration, the shared backplane is the most likely cause since it provides power and communication to every blade installed.
Question
An administrator has been tasked with consolidating six individual servers into one blade enclosure. The administrator completed the task successfully. A week later, all of the blades would not boot properly. Which of the following would MOST likely be causing this issue?
Options
- AThe blade servers are faulty.
- BThe network module on the blade enclosure is faulty.
- CThe backplane of the enclosure is faulty.
- DThe management modules in the enclosure are faulty.

Why each option
When all blades in an enclosure fail simultaneously after migration, the shared backplane is the most likely cause since it provides power and communication to every blade installed.
A faulty blade server would cause only that individual blade to fail, not all blades in the enclosure simultaneously.
A faulty network module disrupts network connectivity after the OS loads but does not prevent all blades from booting.
The backplane is the shared internal bus connecting all blade servers within the enclosure, supplying power, data, and management connectivity to every blade. A faulty backplane would cause every blade to fail at the same time, which matches the symptom of all blades failing to boot after a full migration. Individual component failures would not produce a simultaneous, enclosure-wide boot failure.
Faulty management modules impair out-of-band management access but do not prevent all blades from completing the boot process.
