Free CompTIA Linux+ XK0-005 Practice Question

After expanding an existing disk array on a Linux file server, a systems administrator observes reduced performance during write operations. The original configuration consisted of four disks managed by the server's hardware controller, and a fifth disk was introduced to enhance storage capacity. What is the most probable cause of the observed decrease in write operation speed following the expansion?

  • The block size of the array is not properly configured for the number of disks, leading to inefficient write operations.

  • The overhead of parity calculations is higher now with the additional disk, slowing down the overall write performance.

  • The recent disk added to the server is defective, causing a delay in the array's ability to write data effectively.

  • Suboptimal cable quality is causing a bottleneck in data transfer between the controller and the disks.
