SK0-005 Exam Dumps : CompTIA Server+ Certification Exam

The administrator should rebuild the volume to restore it after replacing the failed hard drive. A volume is a logical unit of storage that can span across multiple physical disks. A volume can be configured with different levels of RAID (Redundant Array of Independent Disks) to provide fault tolerance and performance enhancement. When a hard drive in a RAID volume fails, the data on that drive can be reconstructed from the remaining drives using parity or mirroring techniques. However, this process requires a new hard drive to replace the failed one and a rebuild operation to copy the data from the existing drives to the new one. Rebuilding a volume can take a long time depending on the size and speed of the drives and the RAID level.

To free up storage space on a SAN with minimal effort and no additional cost, the following methods can be used:

Configuring compression (Answer A):Compression reduces the size of files stored on the SAN, allowing more data to be stored in the same space.

Enabling deduplication (Answer E):Deduplication identifies and removes duplicate copies of data, reducing the amount of space required for storage.

Deleting old and unused files (Option B):While effective, this requires manual effort and may not be the best long-term solution.

Increasing the number of IOPS (Option C):This relates to improving performance, not reducing storage space.

Decreasing the RAID level (Option D):Lowering the RAID level could reduce redundancy, which may free up space but also decreases fault tolerance.

Upgrading the filesystem type (Option F):This is a complex process that doesn’t directly reduce storage usage.

The technician should boot from the media to install the firmware on the server. Firmware is a type of software that controls the low-level functions of hardware devices, such as BIOS (Basic Input/Output System), RAID controllers, network cards, etc. Firmware updates are often provided by hardware manufacturers to fix bugs, improve performance, or add new features to their devices. To install firmware updates on a server, the technician needs to boot from a media device (such as a CD-ROM, DVD-ROM, USB flash drive, etc.) that contains the firmware files and installationprogram. The technician cannot install firmware updates from within the operating system because firmware updates often require restarting or resetting the hardware devices.
