After a partition on a hard disk drive is formatted with a filesystem, all partitions on that hard disk drive must use the same filesystem. True or False?

False

Which of the following statements are true?

Quotas can limit both user space and the number of files a user can own. Hard limits can never be exceeded Soft limits allow a user to exceed them for a certain period of time

A command used to identify any users or processes using a particular file or directory

Use the fdisk command to create one or more partitions on each of the hard disk drives. Mount any partitions created on the two hard dries such that they are accessible by the operating system. Format any partitions created with a valid filesystem recognized by Linux

Which of the following statements regarding LVM structure are correct?

VGs are comprised of one or more PVs

The storage devices that transfer data to and from the system in chunks of many data bits by caching the information in RAM
