技術者は、マザーボードの障害のトラブルシューティング中に RAID ハードドライブが機能していることに気づきました。技術者は同様の仕様の予備のマザーボードを取り付け、元のコンポーネントを使用しました。ダウンタイムを最小限に抑えて運用を復元するには、技術者が行うべきことは次のうちどれですか?
正解:C
RAID (Redundant Array of Independent Disks) is a technology that combines multiple hard drives into a logical unit that provides improved performance, reliability, or capacity. RAID can be implemented by hardware, software, or a combination of both. Hardware RAID uses a dedicated controller to manage the RAID array, while software RAID uses the operating system or a driver to do the same1.
In this scenario, the technician noted that the RAID hard drives were functional while troubleshooting a motherboard failure. This means that the data on the drives was not corrupted or lost. However, the technician installed a spare motherboard with similar specifications and used the original components. This means that the new motherboard may not have the same RAID configuration as the old one, or it may not recognize the existing RAID array at all. Therefore, the technician needs to reconfigure the RAID in order to restore operations with minimal downtime.
