CompTIA A+ Core 2 (220-1202)Operating SystemsHard
A technician needs to perform a clean installation of Windows 11 on a new solid-state drive (SSD) for a client. The client wants to ensure that the drive is formatted with a file system that supports advanced features like self-healing, data integrity checks, and improved performance for very large files, which are common in their video editing workflow. Given these requirements, which file system should the technician choose during installation?
- AReFS
- BFAT32
- CNTFS
- DexFAT
Show answer & explanationAnswer & explanation
Correct answer: A. ReFS
ReFS (Resilient File System) is Microsoft's next-generation file system designed for data integrity, scalability, and advanced features like self-healing, which are crucial for demanding workloads like video editing where data corruption can be catastrophic. While NTFS is common, ReFS offers superior resilience and performance for these specific needs.
Why the other options are wrong
- B. FAT32 is an older, legacy file system with severe limitations (e.g., 4GB file size limit) and no advanced features, making it entirely unsuitable.
- C. NTFS is the standard Windows file system, but it lacks the advanced data integrity and self-healing features of ReFS, which are specifically requested.
- D. exFAT is designed for flash drives and external media, supporting larger files than FAT32, but lacks the journaling, security, and advanced data integrity features of NTFS or ReFS. It is not an OS installation file system.
ReFS (Resilient File System)
A Microsoft proprietary file system designed to maximize data availability, scale efficiently to large data sets, and provide data integrity with features like self-healing and checksumming.
- Designed for high data availability and resilience against corruption.
- Includes integrity streams (checksums) for metadata and optionally user data.
- Supports 'integrity scanners' for proactive corruption detection and repair.
- Optimized for large data sets and high-performance storage scenarios.
