A. B. C. D. E.A.
When a server has a faulty hard drive, it is crucial to replace it as soon as possible to prevent data loss and minimize downtime. In this scenario, the administrator needs to replace the hard drive while the server is still running. Therefore, the new hard drive must support hot swapping, which is the ability to add or remove hardware components while the server is still operational.
The correct answer to this question is A. Hot swappable. This means that the server supports hot-swappable hard drives, which can be removed and replaced without powering down the server. Hot-swappable hard drives are often used in RAID configurations, where data is distributed across multiple drives for redundancy and improved performance.
Option B, Hot spare, is incorrect because it refers to a spare hard drive that is pre-installed in the server as a backup in case of a failure. It is not relevant to this scenario.
Option C, SAS (Serial Attached SCSI), is a type of hard drive interface that provides high-speed data transfer rates and supports hot swapping. However, not all SAS drives are hot-swappable, so this answer is not entirely accurate.
Options D and E, USB and Firewire, respectively, are incorrect because they are not suitable for use as internal hard drives. They are primarily used for external storage devices and peripheral devices such as cameras and printers.
In summary, the server needs to support hot-swappable hard drives, which allow for the replacement of faulty hard drives while the server is still running. Therefore, the correct answer is A. Hot swappable.
