Correct Answer:
B. Data redundancy and performance.
Explanation:
The correct answer is Data redundancy and performance. because RAID 5 stripes data and parity information across three or more drives to balance fault tolerance and speed.
- Step 1 (Redundancy through Parity): RAID 5 protects against data loss by calculating parity data and distributing it across all drives in the array, allowing the system to completely reconstruct data if a single drive fails.
- Step 2 (Performance Enhancement): Because data blocks are striped across multiple disks simultaneously, the system can read data from several drives at once, significantly boosting read performance.
- Incorrect Options:
- Speeding up internet connections is incorrect because RAID 5 is a local physical storage configuration that does not affect external network bandwidth or internet speeds.
- Cooling down server rooms is incorrect because storage array configurations relate to data management, whereas cooling relies on dedicated HVAC and fan infrastructure.
- Scanning for malware is incorrect because malware detection is executed by specialized antivirus software applications, not by underlying hard drive storage architecture.
