FC0-U71 Practice Question: Based on the exhibit, what is the most likely…
Exhibit
Refer to the exhibit. Server log entry: [ERROR] Disk write failure at sector 0x3F2. System halted.
Based on the exhibit, what is the most likely cause of the error?
⚠ Common exam trap
A common mix-up: candidates confuse a 'Disk Boot Failure' with a memory or power issue because they all can cause the system to fail to start, but the specific error message isolates the problem to the storage device.
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
✓
Disk error
The exhibit shows a 'Disk Boot Failure' or similar error, which indicates the system cannot find a valid boot sector on the hard drive. This is most commonly caused by a disk error, such as a corrupted master boot record (MBR), bad sectors, or a disconnected data cable. Option D is correct because the error message directly points to a storage device issue, not a network, power, or memory problem.
