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
✓
Place transaction log files on high-speed, low-latency storage.
Separating data, logs, and backups across different physical drives reduces I/O contention and improves recovery speed.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Place data files (.mdf) and transaction log files (.ldf) on the same physical drive.
Why it's wrong here
This creates contention as logs are sequential and data files are random access.
- ✓
Place transaction log files on high-speed, low-latency storage.
Why this is correct
Transaction logs are write-intensive and impact performance if slow.
- ✗
Place backup files on the same drive as the database data files.
Why it's wrong here
If a drive fails, you lose both the data and the ability to restore it.
- ✓
Use separate physical volumes for data files and backups.
Why this is correct
This increases I/O throughput and provides fault isolation.
- ✓
Store data files on a separate physical volume from the operating system.
Why this is correct
This prevents OS overhead from impacting database I/O.
