Selected Answer: B

To recover an LVM-mirrored volume after a failure in one of its physical volumes, the systems administrator should replace the failed drive and reconfigure the mirror. Therefore, the correct option is B. LVM mirroring provides redundancy by creating an identical copy of a logical volume on another physical volume. If one of the physical volumes fails, the system can continue to function using the copy on the remaining volume. To recover the volume, the failed physical volume should be replaced and the mirror should be reconfigured to ensure redundancy is restored. Depending on the configuration of the volume, the system may need to be rebooted to recognize the new physical volume.
